Jeep TJ Conversion Packages

Jeep TJ V8 Conversion Packages

Adding a GM LS V8 engine to your Jeep TJ Wrangler will give you more power, better acceleration and even more efficiency during off-road driving. At Advance Adapters, you can find the right Jeep TJ engine swap kit to make a V8 conversion easily, safely and cleanly. Even after rebuilds and modding, the I4 and I6 engines that came stock on the 1997-2006 Jeep Wrangler lag behind other powerplant options. Use a Jeep TJ LS swap kit to switch to this family of Chevy small block engines that give you the extra horsepower and torque for rock-crawling, overlanding, mudding, snow wheeling and other adventurous outings.

Make a Jeep Wrangler Engine Swap Easier

Going to an LS engine can seem daunting when you think about making all the parts and accessories fit. Among other things, you need to mate the engine to the rest of the powertrain and keep it properly cooled. Sometimes you need to shift other components around and even lift the suspension so there's enough room.

A TJ LS swap kit from Advance Adapters is designed using more than 50 years of four-wheel drive and conversion experience plus feedback from customers. These kits include every component you need depending on your vehicle and your installation goals, including the bell housing, engine mount systems, shifter brackets, pressure plates, radiators, slave cylinders and more. Check each kit to see the components included so you know what you're receiving.

Each of our kits is designed with a specific transmission in mind so making a change perfect for your vehicle is easier than ever. There are Jeep TJ engine swap packages for the NV3550, AX15, AX5 and other factory transmissions. We also have separate kits for Gen 1/2 and Gen 3/4 LS engines to account for the different flywheels.
