TJ/LJ Cummins R2.8 Conversion Kit
- Current Stock:
Our complete R2.8 TJ/LJ kit is designed for Jeep TJ/LJ with Manual Transmissions, and was built around a stock suspension and fenders.
We designed this with aftermarket fenders in mind. Majority of our parts should work with little to no modification for other fenders and suspensions.
With our kit we designed everything around the stock placement of the Transmission and T/C. What this means is you don't have to get new driveshafts, or change any of the T/C shifter linkages.
This kit will not work for jeeps with the 42RLE automatic transmission as there are no standalone controllers available for this trans.
If you are wanting an Automatic Transmission, please call to discuss your options.
Out kit is a full solution and comes with majority of the parts you need to adapt the R2.8 into a TJ\LJ.
Kit does NOT include the R2.8 engine. That is to be supplied by the customer.
Customer will also need to rework there factory wiring harness, and finish out the exhaust from the D0C flange (which is supplied) to the factory muffler.
Note: We tend to run the Banks 2.5" stainless exhaust kit with these engine, as it is high quality and we love the sound of the muffler.
