B & M – Hi-Tek Aluminum Differential Cover for AAM 11.5 – Black (Part No.11317)

Hi-Tek Aluminum Differential Cover for AAM 11.5 - Black

from

$506.99
Our engineers designed the line of Hi-Tek differential covers to not only look good but address a number of weaknesses of the factory-stamped steel covers. First, they started by constructing the covers of thick A356.0-T6 aluminum, which dissipates heat much faster than the factory steel unit keeping the fluid temperature lower under high-stress loads vs. a steel cover. Then for added durability, we added a reinforced center bar for extra strength along with load bolts to help prevent bearing cap deflection under severe loads. The internal shape of the cover retains the smooth round back internally to help keep the fluid flow going over the ring gear to properly lubricate the gears and bearings. Additional features include a magnetic drain plug for catching ferrous metal particles, MIL-Spec (MIL-A-8625) black anodized finish, machined B&M logo, all necessary hardware, and easy-to-follow detailed instructions for a quick and simple installation you can do at home.

Product Features:
  • Load Bolts for Additional Support for Bearing Caps
  • Magnetic Drain Plug for Easy Servicing
  • A356.0-T6 Aluminum Construction
  • Over 65 Years of B&M Quality
  • Limited Warranty
  • Additional Fluid Capacity
  • Black Anodized Finish
  • Machined B&M Logo

Royal Purple – MaxGear SAE 75W90 High Performance Gear Oil w/Friction Modifier Additive, 1 QT (Part No.01300)

MaxGear SAE 75W90 High Performance Gear Oil w/Friction Modifier Additive, 1 QT

from

$24.99
Max Gear is recommended for truck and automotive differentials, outboard motor lower units or in rear axles or manual transmissions requiring an API fluid. Max Gear is a high performance automotive gear oil designed to provide maximum protection to heavily loaded gears while increasing power throughput through the drive train. Max Gear virtually eliminates both gear and bearing wear-even under severe squeeze film conditions caused by extremely high loads, sudden shock loads or low RPMs. Slippery, synthetic molecules not only reduce wear and friction but significantly increase Max Gear’s cold weather fluidity and lubricity, making it the ideal choice for vehicles operating in cold climates. Gears run smoother, quieter, cooler and longer without overhauls. It is noncorrosive to both ferrous and nonferrous metals.

Product Features:
  • Maximizes horsepower
  • Extends gear and bearing life
  • Reduces operating temperature
  • Lower coefficient of friction
  • Superior corrosion protection
  • Separates rapidly from water
  • For use with open, limited-slip and locking differential
  • Contains limited-slip friction modifier
  • Made in USA
