Ring Gear Bolt 8.5in

The Motive Gear Ring Gear Bolt 8.5in (MOT14066913) is a precision differential component engineered for left-hand threaded applications across various Mopar platforms. This 7/16-20 left-hand thread fastener delivers the exact fitment and holding power required for secure ring gear mounting in high-stress drivetrain environments where slippage or misalignment directly impacts differential performance and vehicle safety.

Manufactured from steel with black oxide coating, this ring gear bolt resists corrosion and wear across diverse operating conditions—whether on asphalt, dirt, or extended storage. The hex head design ensures reliable engagement with standard wrenches and sockets, eliminating compatibility issues during installation or removal. At 0.875 inches long with compact dimensions (0.95 x 0.8 x 2.9 inches) and weighing just 0.06 lbs, this fastener fits within original equipment specifications for seamless drivetrain assembly.

Operators and technicians working on Mopar differentials—whether for street performance, off-road duty, or restoration projects—rely on OEM-specification fasteners to maintain drivetrain integrity. The left-hand thread configuration on this ring gear bolt prevents self-loosening under rotational forces, a critical safety feature in high-torque applications. Individual unit packaging allows selective replacement without purchasing full fastener kits, reducing waste and cost for targeted maintenance or repair work.

Ring gear bolt selection directly affects differential assembly reliability. Undersized or mismatched fasteners create stress concentration points; oversized fasteners risk thread stripping or cross-threading. This Motive Gear specification ensures correct clamping force distribution across ring gear contact surfaces, maintaining proper backlash and load distribution during acceleration, braking, and cornering. Serious builders and service professionals specify Motive Gear components for their proven compatibility with Mopar platforms.
