Our posted lead times are only estimations and rely on various factors, many times outside of our control. Historic challenging times within our industry have caused ripples in the supply chain world that have repercussions even on the smallest of components at times. As you would imagine, many companies in our industry are experiencing the same.

Our bed racks are super cool, with the ability to be customized. But this causes a series of challenges due to the thousands of possible combinations regarding compatibility, availability, etc. However, we are constantly aiming at improving our processes, hiring and training our people to achieve a reliable fulfillment process.

If you have additional questions about our lead times, please check our current estimations and reach out to our team if you need additional information. We thank you for your continued support and patience as we improve our processes.

While we would do our best to accommodate a specific need, please do not plan any trips or outings based on the estimated lead times.

THIRD PARTY PRODUCTS

Xtrusion Overland started supplying various brands that go hand in hand with our own products, to provide a complete service and help us grow. This includes products that are drop shipped. Please be advised that availability and lead times of those product are solely impacted by the third-party vendor's schedule. Many products are sold under an open inventory method, as the technology to sync inventories is limited, therefore please reach out if a specific product is needed by a specific date for us to double check with the supplier for you!

Any potential delay that occurs in the sourcing, processing, or drop shipment at the third party level will be communicated to the best of our ability to the customer.

ESTIMATED DATE | LEAD TIMES

The estimated lead time provided when you placed your order is JUST AN ESTIMATE. It is not a guarantee that the product will be shipped on that date. The estimated lead time gives you some sense of what the current times to source, cut, pack and ship takes. Many times the lead time can be shorter, but likewise it can extend, depending on factors such as previous demand and current supply. We manufacture many components in house, but extenuating circumstances such as down time for maintenance or unscheduled downtimes for repairs might impact dates as well as delays related to our sourced components. There is a constant flow of parts and shipments, and sometimes the visibility becomes a challenge to pinpoint exactly when your product will ship.

Feel free to check on your order at any time. Be aware that our customer service team may not be able to give you an exact date for completion but rest assured we are tracking your order and it will be built in the order that it was received.

Xtrusion Overland also reserves the right to cancel items from an order, offer an alternative substitution or issue refund accordingly when product is delayed at an unacceptable time frame or at the request of the customer.

Rack Angle Guide

Overland Rack Angle Compatibility

One Angle.
Every Build.

XTR bed racks use three rack angles — 9°, 13°, and 20° — each matched to specific vehicle setups and accessory families. Find the right angle for your build so every rail, crossbar, and mounting kit lines up perfectly.

Engineered quality

CNC billet strength

We didn't just join the strong extrusions with some sheet metal corner brackets — we put the aluminum where it makes a difference. Every angle variant uses the same 6061-T6 Aerospace grade billet, machined to precision to join all components with exact angular alignment.

✓ All three angles share the same billet standard
✓ 9°, 13°, and 20° brackets machined to exact specs
✓ No sheet metal corners — pure aerospace aluminum

CNC billet corner brackets for XTR bed racks — available in 9°, 13°, and 20° angles

Quick Reference

Angle Compatibility

Rack Angle	Product Line	Compatible Accessories
9°	Gladiator Series	All Gladiator bed racks (XTR1, XTR3 and XBRS), Gladiator mounting kits, Gladiator-specific crossbars, including Softopper versions on Gladiator.
13°	Soft Topper Series	Soft Topper bed racks for all truck models (except Gladiator).
20°	Universal / Crossbars	All XTR1, XTR3, XBRS Bed Racks, universal mounting rails, standard rack accessories (except Gladiator or Softopper)

9° angle

Gladiator Series

The 9° angle is dedicated to the Gladiator product line. This angle was engineered specifically for Gladiator rails and their mounting geometry, ensuring a flush, secure connection between your rails and any Xtrusion add-on accessories. This includes Softopper Gladiator Builds and XBRS for Gladiator.

Xo Skeleton Note: The XO.SKLTN Uses a complete different system not to be confused with Gladiator XTR 9 Degree components.

13° angle

Soft Topper Series

The 13° angle serves Soft Topper products. This intermediate angle provides the right compromise between load clearance and low profile when mounting accessories to Soft Topper rails and their compatible hardware.

Crossbars: XTR1 and XTR3 use 13° when mounted on Soft Topper setups.

20-degree universal rack crossbar — XTR universal and crossbar series

20° angle

Universal / Crossbars

The 20° angle is the default for all other Xtrusion products — universal mounting rails, standard crossbars, and general overland rack accessories. This is the most common angle in the industry and works with the widest range of roof rack and truck bed rack systems.

XBRS: XBRS crossbars use 20° components, the same as XTR1 and XTR3, so the joints stay compatible if you upgrade to a full rack. The one exception is XBRS for the Jeep Gladiator, which uses 9°.

Quick Reference

Xo Skeleton — Angle Breakdown

The Xo Skeleton uses two angles Gladiator Specific or Universal. However, some accessories might be compatible with both, because the top rail consolidates both angles into one. Crossbar mounts or awning mounts are compatible with both versions.

How To Choose

The Right Rack Angle,
Explained

Every XTR accessory — crossbars, mounting brackets, add-on hardware — is cut for one specific angle. The right angle depends on your primary rail system or vehicle setup. Choosing the matching angle ensures every component in your build aligns correctly and carries load as designed.

Identify your rail system. Gladiator = 9°, Soft Topper = 13°, universal = 20°.
Check your crossbar type. XTR1/XTR3 come in all three — order the one matching your rails.
Stick to one angle per build. Mixing angles creates misalignment and stress points.

What determines the rack angle I need? +

Your rack angle is determined by your primary rail system or vehicle setup. Gladiator rails use 9°, Soft Topper setups use 13°, and universal or standard rack accessories use 20°. Choosing the matching angle ensures every accessory — crossbars, mounting brackets, and add-ons — aligns correctly.

Can I use a 20° crossbar with a Gladiator rail? +

No. Gladiator rails are engineered for 9° accessories. Using a 20° crossbar on a Gladiator rail will result in misalignment and improper load transfer. Always match your crossbar angle to your rail system.

Do Soft Toppers and Gladiator rails use the same angle? +

No. Soft Toppers use a 13° angle while Gladiator rails use a 9° angle. These angles are not interchangeable. If you're building with both types, you'll need separate angle-specific accessory sets.

Are XTR1 and XTR3 crossbars angle-specific? +

XTR1 and XTR3 crossbars come in three angle variants — 9°, 13°, and 20° — to match each rack system. The 20° variant is the default and works with universal racks. The 13° variant is used when paired with Soft Topper setups. Order the angle that matches your primary rail system.

Why do overland racks use different angles? +

Different rack angles exist to accommodate varying vehicle roof geometries, rail profiles, and load requirements. The 9° angle works well with Gladiator-style tubular rails. The 13° angle provides a middle ground for Soft Topper mounting systems. The 20° angle is the industry standard for universal applications and offers maximum load clearance.

Description

A third brake light, amber chase light and white scene light in one housing, made for the rear extrusion of your XO.SKLTN topper system. Inside are two US-made Feniex Quad Q3 lights, pre-programmed so the brake, chase and scene functions work out of the box.

Why an XO.SKLTN topper needs its own third brake light

Like any camper shell, a cab-height XO.SKLTN topper sits right behind your truck's factory third brake light, and a rooftop tent on top blocks even more of the view. That's why toppers carry their own brake light. This housing puts one at the top of the XO.SKLTN's rear extrusion, where the driver behind you can see it. The amber chase function makes you easier to follow on dusty trails and convoy runs, and the white scene function lights up the tailgate and the ground behind the truck when you're opening the rear hatch or setting up camp after dark.

Made for the XO.SKLTN system

XO.SKLTN is our all-in-one system: one aluminum frame that runs as a bed rack, closes up as a topper with the topper panel kit, and becomes a camper with the camper tent add-on. This housing is shaped for that frame. It mounts at the center of the rear extrusion, and the harness runs inside the extrusion to a corner bracket and out through the bracket's pre-bored wiring hole, so the wiring stays tucked away instead of crossing your panels or rear hatch.

Because it's on the frame, not on a panel, it stays in place whichever way you run the system:

Bed rack mode, with MOLLE panels, awning mounts or a rooftop tent on top
Topper mode, with the topper panels and rear hatch installed
Camper mode, with the camper tent add-on set up

It fits XO.SKLTN systems on every truck we build them for — Toyota Tacoma and Tundra, Ford Ranger, F-150, Raptor and F-250/F-350, Chevy Colorado/GMC Canyon, Silverado/Sierra 1500 and 2500HD/3500HD, Ram 1500 and 2500/3500, Nissan Frontier and Titan, and the Jeep Gladiator.

XO.SKLTN or XTR: which version do you need?

We make this light in two versions, and the housings are physically different. This one is for the XO.SKLTN. If you run an XTR1, XTR3 or XBRS bed rack, order the XTR Third Brake Light & Chase Light Housing instead. Both versions use the same Feniex Quad Q3 lights, wiring and camera options.

Choose your version

With Camera Opening: a cutout for a WolfBox rear camera
No Camera Opening: a clean face, lights only
Third Brake Light With WolfBox G900 PRO: the camera-opening housing plus a WolfBox G900 PRO smart dash cam and camera. When the topper panels block the view out your rear window, the camera at the top of the rear extrusion shows you what's behind the truck.

Every housing comes in matte black or gray.

Brake, chase and scene lighting

Red brake light (dimmed setting), triggered by your truck's brake light output
Amber chase light at full brightness, on its own switched circuit
White scene light at full brightness, on a switch or on your reverse circuit, where it doubles as backup lighting

The Feniex Quad Q3 is a four-color light (red, blue, amber and white) that Feniex makes for police and first-responder vehicles. Each light can be reprogrammed with other colors and patterns; if you do, it's at your own risk, since blue light isn't legal on civilian vehicles. Follow the Feniex Q3 instructions, and look up your state's rules before using chase or scene lighting while driving.

In the box

One housing, 3D printed from carbon-fiber-filled PETG (CF PETG) in matte black or gray
2 Feniex Quad Q3 lights, programmed for brake, chase and scene lighting
Wiring harness: a sealed IP67 4-pin plug a few inches from the housing lets you disconnect the light. From the plug, about 9 ft of wire runs to bare ends that you connect to your truck's brake, reverse and switched circuits.
With the WolfBox G900 PRO version: one WolfBox G900 PRO smart dash cam and camera, plus a USB-C hardware kit

Not included: no version includes switches. The WolfBox camera comes only with the Third Brake Light With WolfBox G900 PRO version; the With Camera Opening housing has the cutout, but no camera.

How it installs

Mark the center of the XO.SKLTN's rear extrusion and drill a 1/2" hole.
Run the harness into the hole and through the extrusion to a corner bracket. Open that bracket's pre-bored wiring hole and pull the wire out.
Seal the 1/2" hole and the wire exit at the corner bracket with RTV silicone. The XO.SKLTN topper is weather-tight, not waterproof, so sealing keeps water out of the frame and away from the wiring.
Match the leads (the wiring photo shows them): black is ground; blue powers the red brake light, brown the amber chase light and green the white scene light, each at +12V. Wire colors may vary.
Connect blue to your truck's brake light output, brown to a switched circuit and green to a switched or reverse circuit. Look up your truck's wiring options first.

FAQ

Will this fit my XO.SKLTN?

Yes. It fits the rear extrusion of XO.SKLTN systems on every truck we build them for. Running an XTR1, XTR3 or XBRS rack instead? Order the XTR version; the housings are different.

Does it work with the topper panels on and off?

Yes. It mounts on the XO.SKLTN frame, not a panel, so it works in bed rack, topper and camper mode.

Why does a topper need its own third brake light?

A cab-height topper, or a rooftop tent on top of it, can hide the third brake light on your cab. A light at the top of the topper's rear keeps a center brake light in view of the driver behind you.

Can I use the chase and scene lights on the road?

That depends on your state. Rules for amber and white rear lighting vary, so check your local laws first.

Do I need switches?

Yes, since none are included with any version. Most setups use one switch for the chase light and one for the scene light; if you wire the scene light to your reverse circuit, it doesn't need one.

Can I reprogram the lights?

You can, using the Feniex Q3 instructions, at your own risk. Don't use blue: it isn't legal for civilian vehicles.
