🔥 WHAT AN ABSOLUTE BAD ASS TRANS BUILD! 🔥

This one is pretty much a full RevMax build and it turned out SWEET! 💪

🔩 RevMax billet pump cover
🔩 Full RevMax valve body with all billet accumulators
🔩 Billet flex plate
🔩 Goerend billet input shaft
🔩 “Big Stack” clutch packs

Built to handle some serious power and abuse. 💪🔥

Another nasty build heading out the door! 🛠️

If you own a 6.7 Power Stroke, the S&S Diesel DCR conversion is one of the best upgrades you can make.

For just $1,200 installed, we can have your truck in and out the same day.

Ask yourself this: would you rather spend $2,500 on prevention, or $15,000+ replacing a fuel system after a CP4 failure?

The CP4 pump has a well-known history of failures, and when it lets go, it can send metal through the entire fuel system—turning a simple upgrade into a very expensive repair.

Don’t wait until you’re stranded. Get ahead of the problem and protect your investment.

Even if your old diesel truck has been sitting in the weeds or parked behind the barn for years and you think the job is too far gone — think again. At J&R Diesel we love bringing old trucks back to life.

This customer’s 2001 Cummins had been sitting for a long time, but we got it diagnosed and back on the road where it belongs. We replaced the VP44, fuel filters, battery terminals, and gave the whole truck a thorough check-over to make sure it was ready to roll again.

Don’t let your old project or work truck rot away — give us a call and let J&R Diesel bring it back to life.
