Product Details

The Yukon Gear & Axle ZG GM8.5-513 is a high-performance ring and pinion gear set engineered specifically for GM 8.5-inch rear differentials. This USA Standard gear set features a 5.13:1 ratio, providing improved acceleration and torque multiplication for trucks, SUVs, and performance applications running larger diameter tires or requiring better low-end power.

Key Features:

  • 5.13:1 gear ratio optimized for GM 8.5-inch differentials
  • Precision-manufactured using advanced CNC machining and heat treatment processes
  • Engineered tooth design for quiet operation and maximum strength
  • Ideal for vehicles with oversized tires or towing applications
  • Easy installation with standard setup procedures
  • Backed by manufacturer's one-year warranty

USA Standard Ring & Pinion sets are manufactured to strict tolerances using the latest gear design technology, ensuring proper tooth contact, reduced noise, and long service life. The 5.13 ratio is particularly popular for restoring lost performance when upgrading to 33-35 inch tires or for applications requiring aggressive acceleration and improved towing capability. Each gear set is quality inspected to meet OEM specifications for fit and durability.

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!!!

I ordered an exhaust setup (headers and a cat-back) late monday night, an it was shipped on wednesday. Thanks for a fast transaction Autoplicity!

Good price for great name brand car parts. AEM fuel filter very low price and new. Hope the shipping is as great as the price. :)

Great website and the ordering was easy too. I like the way they show the full price including shipping and tax. Got the confirmation immediately and the shipment notification the next business day. <br>

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
