DO YOU HAVE FRONT DIFF NOISE? IS YOUR 4WD LOCKED UP?/h1>
YOUR DIFF IS FAILING
Your Differential Case isn’t the problem. The OE Front Differential is a capable design but many of the internal components are manufactured overseas, which results in poor quality and high failure rates. Your Bearings, Sprague, Spring Retainer & Seals are the high failure points.


BEST – BOMBPROOF DIY KITS
Winner of the BAJA 1000 2020, the steel sprague BOMBPROOF kit’s name says it all. Heat Treated Carbon Steel (10X STRONGER THAN OEM) 2-Piece bombproof sprague and armature plate with upgraded seals, bearings, pin and spring retainer. This is the best we have to offer.
BETTER – BULLETPROOF DIY REBUILD KITS
The BULLETPROOF kit by SANDCRAFT replaces the seals, dowell pin and bearings but also upgrades the critical 4WD components including the Sprague Carrier, Armature Plate and Spring Retainer. These kits eliminate all cheap metal and plastic components completely.
GOOD – BEARING AND SEAL DIY KITS
These kits are easy on the ears and the wallet. Replace your leaky seals with SANDCRAFT Seals and the best quality bearings you can buy to reduce noise and failure rates. A solid tapered dowell pin is also included where applicable.
