CPP Diesel curates proven ring & pinion sets, master install kits, lockers & limited-slips, differential covers, wheel hub/bearing assemblies, U-joints & yokes, and axle hardware for the 1998.5–2002 Ram 2500/3500 with Dana 60/70/80 axles.
Complete your build with STEERING / SUSPENSION stability and BRAKES for control under load.
Heavier trailers or larger tires benefit from numerically higher ratios (e.g., 4.10+). For mixed daily/tow use, many 24-valves are happy at 3.73–4.10. We can help match ratio to tire size and cruising RPM.
Lockers (air/electric) provide maximum traction when engaged; helical limited-slips improve grip with smooth manners. Choose based on terrain, snow/ice use, and budget. See examples like the Yukon Zip Locker.
Use complete units such as Dorman 951-834 (01–02 2500 4WD / 00–02 3500 4WD)—confirm ABS and axle options before ordering.
Yes—high-capacity finned covers like MAG-HYTEC and ATS increase fluid volume and cooling area for towing/heat control.
If your housing, gears, and bearings are tired, a Zumbrota reman assembly can save setup time and include new wear parts—core return required.
