Product Details

The Yukon Gear & Axle ZG F9-513 is a USA Standard ring and pinion gear set engineered for Ford 9-inch differentials with a 5.13:1 gear ratio. This gear set is designed to deliver reliable performance for street, off-road, and performance applications requiring lower gearing for improved acceleration and torque multiplication.

Key Features:

  • 5.13:1 gear ratio for enhanced torque and acceleration
  • Designed specifically for Ford 9-inch rear axle assemblies
  • Exceeds OEM specifications for quality and durability
  • Undergoes rigorous in-house dimensional, material, and fitment testing
  • Precision-cut gear teeth for quiet operation and long service life
  • Ideal for lifted trucks, rock crawlers, and vehicles with larger tire diameters

USA Standard Gear sets are manufactured to strict tolerances and quality standards, ensuring proper fitment and reliable performance. The 5.13 gear ratio is particularly popular for off-road vehicles and street machines that need to regain optimal RPM range after installing larger tires or for drivers seeking improved low-end torque. Professional installation with proper setup and break-in procedures is recommended for optimal performance and longevity.

Very content, look to shop again if need arises.

good pricing on a lot of parts

So Far So Good!

Autoplicity was easy to order from price was great. But not a fan of Fedex never have been took two trips to get what i ordered one day and then the next.

I am very pleased with the customer service and quality of the product provided by your company.

Fast shipping quality product A+ all around

The best price for Hyperco coilover springs

Great Company with awesome support!!

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!!!

Very easy to use website, Found the right match and checked out easy. Parts easy to install, was to read and understand directions. Quality product.

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>
