Product Details

The B&M 71504 Hi-Tek Aluminum Differential Cover is engineered to provide superior protection and enhanced cooling for GM 8.875-inch 12-bolt truck differentials. Constructed from robust A356.0-T6 aluminum alloy, this differential cover combines lightweight durability with increased fluid capacity to keep your drivetrain running cooler under demanding conditions.

Key Features:

  • Precision-machined from A356.0-T6 aluminum for exceptional strength-to-weight ratio
  • MIL-spec black anodized finish provides corrosion resistance and a sleek appearance
  • Additional 0.5-quart fluid capacity helps improve heat dissipation and extends service intervals
  • Magnetic drain plug captures metal particles and simplifies differential servicing
  • Load bolts deliver extra support to bearing caps, reducing deflection under heavy loads
  • Machined B&M logo adds a custom performance look
  • Backed by B&M's Lifetime Limited Warranty and over 65 years of drivetrain expertise

This differential cover is ideal for truck owners looking to upgrade their GM 8.875-inch 12-bolt rear end with enhanced cooling capacity, easier maintenance, and added structural support. The increased fluid volume and efficient aluminum construction help manage heat during towing, off-roading, or performance driving.

Not pleased when I got an error when paying with credit card.

Good price. So far so good

I bought a Motive pressure brake bleeder from Autoplicity. I have been looking around for different prices for quite a while, and their price, even with shipping cost, was the lowest. After ordering, I received a notification of shipment and tracking number. The item arrived well packaged, complete, and intact within a few days. I am looking forward to using it.
