S/S Rear End Cover Bolt Kit - 10-Bolt Chevy

The ARP Stainless Steel Rear End Cover Bolt Kit for 10-Bolt Chevy differentials is a purpose-built fastening solution designed to secure differential covers on GM 10-bolt rear axle assemblies. This kit consists of ten 5/16-18 stainless steel bolts, each 0.750 inches in length with a polished 12-point head configuration. The stainless construction resists corrosion from road salt, moisture, and harsh environmental exposure—a critical factor for vehicles operating in coastal regions, winter conditions, or high-mileage service where differential integrity depends on secure fastening.

The 5/16-18 thread specification and 0.750-inch length are engineered to match OEM bolt patterns on GM 10-bolt differentials, ensuring proper engagement without bottoming or thread stripping. The polished stainless finish provides both corrosion resistance and visual appeal, eliminating the dulling and oxidation common to zinc-plated fasteners. The 12-point head design distributes load across a wider bearing surface compared to six-point heads, reducing stress concentration at the bolt head and improving resistance to galling during installation and removal cycles. For rebuilds, restorations, and high-performance applications where differential cover security is non-negotiable, these bolts offer the material and geometric precision that OEM fasteners provide.

This kit serves technicians, restoration shops, off-road builders, and DIY enthusiasts performing differential service, gear replacement, or fluid maintenance on Chevy trucks and performance vehicles equipped with 10-bolt rear axles. Whether you're rebuilding after a fluid flush, upgrading to a performance differential cover, or restoring a classic Chevy, ARP's stainless fasteners eliminate the risk of bolt failure or corrosion-induced leaks that compromise differential performance and create safety hazards during towing or high-load driving.

ARP fasteners are engineered for reliability in demanding applications where standard hardware fails. The stainless material specification and controlled manufacturing tolerances distinguish this kit from bulk hardware store bolts, ensuring repeatable fitment and consistent performance across multiple installations.
