Ring Gear Nut & Bolt Kit

The Winters Ring Gear Nut & Bolt Kit (Part Number 7165) is a precision fastening solution engineered for differential assembly, repair, and rebuild applications where OEM-specification hardware is critical. This kit delivers the exact 3/8-24 thread fasteners needed for ring gear mounting on non-threaded ring gear differentials, ensuring proper torque retention and positional stability under high-load conditions.

The kit features slotted-head bolts and matching nuts in black oxide or cadmium finish—both finishes providing corrosion resistance essential for differential housings exposed to moisture and road salt. The 3/8-24 UNC thread pitch is the industry standard for this application class, and the black oxide coating offers superior durability in wet environments compared to bare steel. Each component is manufactured to close tolerances, ensuring repeatable engagement and secure fastening across multiple installation cycles.

Technicians rebuilding differentials for street, off-road, or performance applications rely on kit fasteners like this to maintain OEM specifications without sourcing individual bolts from multiple suppliers. The slotted head design accommodates standard flat-blade fastening tools and allows for positive lock confirmation during torque-down operations. This kit is compatible with Winters quick-change differentials and similar non-threaded ring gear housings requiring 3/8-24 fastening hardware.

Whether you're performing a full differential overhaul, replacing worn fasteners, or building a complete gearset assembly, having the correct fastening kit on hand eliminates downtime searching for compatible hardware. The compact 0.87 lb kit stores easily in a toolbox and provides everything required for one complete ring gear fastening application.
