I've only driven the truck a few miles but a few things stand out. The RTs have always had a left hand pull but it's completely gone and the truck tracks perfectly straight. Grooves in the road no longer pull the truck either. Feedback through the wheel is greatly minimized.

I'll know tomorrow, I kept it 50mph and under today. 50mph in 6th gear runs about 1500 RPM.

A few observations. The transmission feels like it is holding less torque. I don't know if I'm just hyper sensitive but I haven't had any clunky shifting today. I did calibrate the computer to 4.88 with a ProCal, no idea if that does anything at all though. Also, the truck holds 6th going up hill where it used to down shift into 5th or 4th.

As far as installation goes, I was going to do the install but I found a local installer that knew what he was doing. I used AAM 11.5 OE Chrysler 5.13, these are gears out of an older Cab and Chassis 3500 and are different that OE AAM 11.5 Chrysler 4.10 or 4.30. This R&P requires pinion conversion bearings and the crush sleeve to be machined slightly shorter. There might be an off the shelf sleeve available but the supplier was unaware of it. The front gears are Yukon 9.25 GM 5.13 with a Yukon Chrysler application conversion spacer and ring gear bolts. There was some concern about the length of the ring gear bolts included with the spacer being too short. However, the Yukon bolts are actually longer than the OE ring gear bolts. The gears set up fine, the only hang up was sourcing the correct pinion bearings and then machining the spacer.

Just curious, what are your RPMs with the 5.13s in 6th gear at 65mph and 75mph?

Nice work on your truck, that things is a real beast.

2000 RPMs at 70mph.
