ARP 250-3009 Cylinder Head Fasteners
Ring Gear Bolt Kit
For 8in Rear
The tremendous shock loads generated at launch by most any drag
racing vehicle equipped with todays sticky tire compounds or the
acceleration and deceleration of oval track cars put considerable
strain on the ring gear. For this reason, the fastener experts at
ARP have developed the Pro Series ring gear bolts.
Theyre forged from premium grade 8740 chrome moly steel and are
heat-treated to a nominal rating of 200,000 psi tensile strength.
Specially hardened, precision-ground washers are included where
required. Available to fit most any ring gear setup ranging from
popular 9 Ford GM 10 & 12-bolt rear ends to the
beefy Strange differentials found in Top Fuel and Funny Car
It is critically important to properly tighten ring gear bolts and
make sure they dont loosen. This is especially important in drag
cars with tire shake. Its also a good idea to check bolt tightness
on a routine basis. If you use a locking compound (like Loc-Tite),
it is best to install the ring gear first without any compound,
then remove the bolts one at a time, reinstalling them with the
compound. Be sure and torque each bolt before going on to the next
one, because the Loc-Tite sets up fast. Install and torque the
bolts in an alternating or crossing pattern to distribute the load
evenly around the ring gear.
