Product Details

The Yukon Gear & Axle YSPSPR-004 is a replacement Trac Loc spring designed specifically for Ford 8.8-inch rear differentials with 28-spline axles. This spring is a critical component in limited-slip differential clutch packs, providing the preload pressure necessary for proper Trac Loc operation and torque transfer between axles.

Key Features:

  • Engineered for Ford 8.8-inch rear axle assemblies
  • Compatible with 28-spline axle shafts
  • Direct replacement for worn or weakened Trac Loc springs
  • Restores proper clutch pack preload and limited-slip performance
  • Manufactured to OEM specifications for reliable fitment

Over time, Trac Loc springs can weaken or fatigue, resulting in reduced limited-slip effectiveness and poor traction performance. Replacing worn springs during differential service or rebuild helps restore factory-level performance and ensures consistent power distribution to both rear wheels during acceleration and cornering.

Great prices and simple Amazon account checkout.

Quick and easy. Cheap to.

It was quick and easy to find what I needed.

I'm a stickler for finding the best prices on my purchases, while also making sure that the products I buy are legit and not some cheapo knock-offs.<br>I did my homework on the Clutch Stage 2 kit I wanted for my Spec V and found that Autoplicity had the best price anywhere, even a spot where I had 10% off came out to be more expensive.<br><br>I received my Clutch Stage 2 clutch kit pretty quickly (about 1 week) and everything was as expected.<br><br>Overall I would rate Autoplicity a perfect 10, although I did not have to contact their customer service or initiate a return, so the '10' would be on product selection, communication, website experience, and overall feeling that I got the best deal out there.<br><br>Thanks!
