Four-Wheel Drive Adapters

Repairing, restoring and customizing a 4WD vehicle is always easier with the right adapters.

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.

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.

Some of these parts also can be used to r fine-tune your setup for the right amount of power and torque.
