7 1/2 Inch GM Ring Gear Spacer with Bolts
SKU-91048305
                        

Allows you to install a bigger series gear set onto a smaller series carrier. Precision ground to ensure trueness and provide proper backlash. Fits 7.50" diameter ring gear with 1.438" diameter pinion (27 spline). Longer, LH thread ring gear bolts are included with this spacer.

Red Line 58204 Heavy Shockproof Synthetic Gear Oil, 1 Quart
SKU-60720100
                        

Red Line Shockproof synthetic gear oil is designed for heavily loaded racing and street differentials that see heavy shock loading. It contains a unique solid dispersant that cushions gear teeth to help prevent breakage. Red Line Shockproof gear oil provides the protection of a 75W250 with the fluid thickness properties of a 75W90.

Ideal for use in sprint, midget, and dirt late model differentials as well as in rear ends using spools or lockers.

  • Fully-synthetic gear oil formula created from polyol ester base stocks offers excellent lubrication under extreme conditions
  • High viscosity-index to provide relatively constant viscosity and film thickness with varying temperature change
  • Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oil
  • Exceed API GL-5 specifications
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
  • Not recommended for most synchro applications due to the product's extreme slipperiness
