Jeep TJ V8 Conversion Packages

Installing a V8 in a Jeep TJ Wrangler is one of the most effective upgrades for increasing power, torque and overall trail performance. Adding a GM LS engine transforms how your 1997 to 2006 Jeep drives, offering stronger acceleration, better efficiency and improved capability in demanding off-road environments. At Advance Adapters, you will find premium Jeep Wrangler LS swap kit options that allow you to complete a clean, reliable and straightforward conversion.

Even after rebuilds or mild modifications, the original I4 and I6 engines struggle to match the output of a modern LS powerplant. A TJ LS swap gives your Jeep the horsepower and torque needed for rock crawling, overlanding, mudding, snow wheeling and any adventure where responsiveness and low-end power matter.

Make Your Jeep Engine Swap Easier

Swapping in an LS engine to create a V8 in a Jeep can seem intimidating. The conversion requires proper alignment, cooling and integration with the existing drivetrain. You may need to adjust accessories, relocate components or lift the suspension depending on your configuration.

A TJ LS swap kit from Advance Adapters simplifies the entire process. Backed by more than 50 years of drivetrain expertise, each package is engineered to include the necessary components for your specific vehicle and transmission setup. Kits may include bellhousing adapters, engine mount systems, shifter brackets, pressure plates, radiators, slave cylinders and other essential parts. Each kit lists its included components so you know exactly what is provided.

These packages are designed for specific factory transmissions such as the NV3550, AX15, AX5 and more. We also offer kit variations for Gen 1 and 2 LS engines as well as Gen 3 and 4, depending on the flywheel and drivetrain requirements. Whether you are upgrading a TJ or researching a Jeep JK LS swap kit, our engineering approach delivers compatibility and simplicity.
