When I ran my 44, I had installed the Teraflex big brake kit and optional master cylinder. When I swapped to the RJ's, I still have the larger rotors but had to go back to the original single piston calipers. They do work pretty well but was curious about adapting a dual piston caliper with larger pads. Looked around at Napa and decided on these from an 08 Ram 1500 4x4.
Picked up so 1/2" thick bar stock and started roughing out the new mounting adapters.
Drilled and tapped. Had to get some longer bolts due to the mounting ears of the calipers being wider. Also had to reduce the size of the spacer to account for these.
All mounted up and compared to stock caliper
Nice pedal feel and great braking power. I don't have any scientific data to compare but "seat of pants" says well worth it.
