Product Details

The Yukon Gear & Axle ZG GM8.5-538 is a high-performance ring and pinion gear set designed for GM 8.5-inch rear differentials. This gear set features a 5.38:1 ratio, providing excellent acceleration and torque multiplication for off-road, towing, or performance applications with larger tires.

Key Features:

  • 5.38:1 gear ratio for improved low-end torque and throttle response
  • Fits GM 8.5-inch rear axles (requires notched cross pin design)
  • Manufactured in the USA using advanced gear cutting technology
  • Precision-engineered tooth design for quiet operation and durability
  • Heat-treated alloy steel construction for maximum strength
  • Designed for easy installation and setup
  • Backed by a one-year manufacturer warranty

This gear set requires a notched cross pin (X-pin) differential case for proper installation. The 5.38 ratio is ideal for vehicles running 35-inch or larger tires, restoring lost power and improving drivability. USA Standard Gear sets are engineered to meet or exceed OEM specifications for reliable performance in street, off-road, and heavy-duty applications.

Easy shopping and best, or close enough, price.

First time buyer. Giving you a chance.

best price found, easy order process. Free shipping a BIG plus!

I just bought two of the new Aeromotive pumps from autoplicity at the best price found online.. They were shipped out quick and arrived even faster than I thought. Autoplicity.com will be in my favorites when it comes to ordering parts for my 94 Supra from now on!!!

Easy to navigate website with great prices.

using amazon pay is easy I was not able to track the UPS shipment until the day of delivery. Maybe the number did not scan correctly at the time of shipment. Customer service did show it was shipped on time, and it arrived quickly.
