Product Details

The Motive Gear GM82373E Excel Ring and Pinion Gear Set is engineered for GM 8.2-inch rear differentials in 1955-1964 applications. This precision-matched gear set delivers a 3.73:1 final drive ratio, providing an excellent balance of acceleration and highway efficiency for classic GM vehicles.

Key Features:

  • 3.73:1 gear ratio for improved performance and drivability
  • Designed specifically for GM 8.2-inch rear axles (early 1955-1964 models)
  • Excel series quality with precision-cut gearing for quiet operation
  • Case-hardened steel construction for maximum durability
  • Computer-controlled CNC machining ensures optimal gear tooth contact
  • Sold as a matched ring and pinion set for proper mesh and longevity

Motive Gear's Excel line offers high-quality replacement gears at a value price point, making them ideal for restoration projects, gear ratio changes, or replacing worn differential components. Professional installation with proper setup tools and measurements is required to ensure correct backlash, bearing preload, and gear pattern.

Can't believe the price :) unbelievable, very good for poor people

Navigation was very good, having parts in stock was a plus. Hopefully processing and shipping out order is as quick.

Quick and easy but I'd like to have my part before writing a review

I purchased an extend-a-truck on autoplicity. It was the best price on the Internet. Autoplicity beat amazon by approximately $30. I received a confirmation it shipped the following day.

"Great prices and quick shipping. I was impressed on how easy it was to order online!"
