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.
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

Angle Compatibility
| Rack Angle | Product Line | Compatible Accessories |
|---|---|---|
| 9° | Gladiator Series | All Gladiator bedracks, 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) |

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

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.

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.
Exception: XBRS Crossbars use 9 Degree components, in case you decide to upgrade to full rack, so it remains compatible on joints.
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.
9° Angle
XOSKLTN Gladiator
- Gladiator rail mounts
- Gladiator-specific hardware
- Gladiator crossbar slots
13° Angle
XOSKLTN
- Soft Topper rail mounts
- Soft Topper mounting kits
- Soft Topper crossbar slots
Note: The Xo Skeleton never uses the 20° angle.
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.
