Ford 9in Ring Gear Bolt Kit .940 UHL

The Ford 9in Ring Gear Bolt Kit .940 UHL from ARP is a precision-engineered fastening solution designed for professionals who demand reliability in high-stress drivetrain applications. Built for Ford 8.8 and 9-inch differentials, this ring gear bolt kit serves heavy-duty users including mechanics, fabricators, and performance enthusiasts who require OEM-quality or superior replacement fasteners. Ring gear bolts anchor the differential's most critical rotating component, and any compromise in material or design compromises vehicle safety and drivetrain longevity.

This kit comprises ten chromoly bolts manufactured to ARP's exacting standards and finished in black oxide for corrosion resistance and professional appearance. Each bolt features a 7/16-20 inch thread specification, 0.94-inch length, and a 12-point head design that maximizes contact area and reduces fastener rounding under high torque loads. Chromoly steel provides superior tensile strength compared to standard grade bolts, critical when ring gears experience shock loads during acceleration, deceleration, and off-road use. The black oxide coating protects against rust and degradation in harsh underbody environments while maintaining consistent friction characteristics for accurate torque application.

Technicians restoring or upgrading Ford 8.8 and 9-inch differentials will find this bolt kit essential for reassembly, particularly in cases where original fasteners show wear, corrosion, or damage. Professional installers and fabricators appreciate the 12-point head configuration, which reduces the risk of fastener failure during torque-down procedures and provides superior grip compared to 6-point alternatives. Installation requires standard metric sockets and a calibrated torque wrench set to manufacturer specifications for the Ford platform; ARP publishes precise torque values to ensure proper clamping force without exceeding material yield strength.
