Description
Proper ring gear spacing is critical for differential assembly—it ensures correct backlash and prevents premature gear wear that can compromise your entire drivetrain. This Allstar Performance spacer delivers the precision fit your GM 10-bolt differential demands, eliminating guesswork during assembly and helping you achieve the tight tolerances that separate a reliable setup from a catastrophic failure.
Whether you’re rebuilding a street machine or prepping for competition, this kit includes everything needed for a professional-grade installation without the fabrication headaches.
