The factory installed ring gear bolts are TTY (Torque To Yield) and are only designed to be used one time. We offer an Bolt Kit from ARP that has the (8) ring gear bolts and (4) bearing cap bolts (enough for one Differential). These bolts are much higher quality with rolled threads and can be used over and over again. We feel like this is added insurance to help keep you H1 Hummer / HMMWV more reliable when your tearing it up on an adventure.
One kit is for one Differential.
Note: We have developed new torque specs for this product that are different than factory to increase clamping forces safely. They are lower torque numbers than factory because the factory uses TTY (torque to yield):
- ARP MM Ring Gear Bolts 75ftlbs
- ARP MM Main Cap Bolts 90ftlbs
