Differential Overhaul Kits

Differential overhaul kits supply the bearings, seals, and shims needed to eliminate play, noise, and leaks in a tired differential. Whether you're addressing a persistent whine, a clunk during engagement, or prepping for a ring-and-pinion swap, these kits bundle the wear items that restore proper backlash, preload, and fluid sealing.

  • Typical kits include carrier bearings and races, pinion bearings and races, a pinion seal, crush sleeve or solid spacer, and ring gear bolts.
  • Many also contain threadlocker, marking compound, and a cover gasket or RTV where applicable.
  • Bearings are produced to tight tolerances that mirror OE specifications, ensuring reliable function under load.
  • Seals resist high-temperature gear oil and thermal cycling to maintain a leak-free housing.

Choosing the correct kit means matching your differential type (open, limited-slip, locking) and axle model. Steps like counting ring gear bolts and checking the carrier break help narrow the selection. If you need assistance, our support team can walk you through identifying the right overhaul kit for your rebuild.
