Third Party 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.

Description

If you’re upgrading your 80 Series to a CS144 high-output alternator, this harness makes the wiring portion of the swap clean, simple, and reliable.

The factory charging system on the 1993–1997 Land Cruiser and LX450 uses a Toyota oval 3-pin connector (IG–S–L). Most CS144 alternators use a GM-style regulator plug, which usually means cutting and splicing your factory wiring. This plug-and-play adapter eliminates the guesswork and lets you connect your high-output alternator the right way — no hacked wiring under the hood.

Whether your build includes a winch, dual batteries, lighting, onboard air, a fridge, or a full overland electrical system, a CS144 upgrade helps your 80 Series keep up with modern electrical demands — especially at idle.

Built in-house by TEQ Offroad for Land Cruiser owners who actually use their rigs. Finished in classic Toyota retro colors as a small nod to the heritage — even when you’re running GM charging power.

Why Upgrade to a CS144?

The factory alternator is typically 80–100 amps. Once you add modern accessories, charging performance — especially at idle — becomes a limitation.

A CS144 provides:

Higher output at idle
Support for winches and dual battery systems
Stable voltage for overland accessories
Proven durability for expedition and off-road use

Built for Land Cruiser Owners

At TEQ Offroad, we design parts the way we’d want them on our own trucks — simple, durable, and made to work the first time. No shortcuts. No unnecessary complexity. Just a clean solution for a common 80 Series charging upgrade.
