Rotating Weight Savings for Faster Acceleration & Quicker Times
Sample 8620 Ring Gear Weights
Xtreme 5.67 ring gear weighs 9.0 lbs.
LW PEM 5.67 ring gear weighs 11.65 lbs.
Standard PEM 5.67 ring gear weighs 12.95 lbs.
Acceleration is improved with weight reduction in the drivetrain. The larger the diameter of the part the more weight reduction helps. Your flywheel and rear ring gear are the largest diameter parts in your drivetrain and will benefit the most from weight reduction.
The ring gear is narrower than a stock ring gear and requires a matching offset spool to reduce the weight and not to reduce strength.
Assembled Package includes: NEW PEM Nodular Iron Case & pinion support, pinion bearings & races, pinion bolts, pinion depth shims, pinion seal, pinion nut, side bearings & races, ring gear bolts, tail bearing and tail bearing retainer plate.
All bearings and seals are Premium Brands (either Timken or Koyo).
Fully assembled 9" Ford center sections are ready to install, complete with new iron case, pinion support, premium bearings, 1310 pinion yoke, solid pinion spacer, and standard ring and Pinion gears for 31-spline axles.
