Four-Wheel Drive Adapters

Repairing, restoring and customizing a 4WD vehicle is always easier with the right adapters. If you’re using components that didn’t come stock with a truck or SUV, adapters are necessary to connect them to the OEM parts — or other aftermarket upgrades. Since 1971, Advance Adapters has been developing quality conversion products made in the U.S. Shop hundreds of 4WD adapters for Jeeps, Fords, Chevys and other popular off-road vehicles.

Off-Road Adapter Kits

We offer 4WD adapter kits and parts for almost any DIYU project. Use transmission-to-transfer case adapters and engine-to-transmission adapters to mate a variety of popular components, such as connecting a GM TH350 transmission to a Jeep Dana 300 transfer case. Our team has also put together 4WD conversion packages that include the hardware and accessories needed to install new transmissions. With retrofit kits, you can add an AX15, NV4500, NV3550 and other transmissions to your existing engine while utilizing the available space.

4WD Adapter Hardware

If a part has failed within your current conversion, you don’t need to replace the entire assembly. Individual hardware and accessories are available to fix your custom vehicle at a fraction of the price. Shop spline outputs and inputs, couplers, gears, seals and other components made of premium materials. Some of these parts also can be used to r fine-tune your setup for the right amount of power and torque. Use the search options to find adapters that fit your goals or call to speed with a four-wheel drive expert. We provide leading customer service to support our leading conversion products.
