Product Details
The Honda OEM K-Series Differential Ring Gear Bolt is a genuine factory replacement designed for select Honda and Acura manual transmissions equipped with an open differential. This specialized 11mm fastener secures the differential ring gear to the differential assembly, providing the clamping force required for reliable operation and proper power transfer.
Commonly used in Honda K20 and K24 manual transmission applications, this genuine Honda bolt is an essential component when rebuilding a transmission, replacing differential components, or servicing the final drive assembly.
The differential ring gear plays a critical role in transferring engine power through the transmission to the drive wheels. Its mounting bolts must withstand substantial rotational loads, drivetrain vibration, and repeated acceleration and deceleration while maintaining a secure connection between the ring gear and differential.
Manufactured to Honda's original equipment specifications, this genuine ring gear bolt provides factory-correct fitment and fastening characteristics for compatible open differential applications.
Whether you're rebuilding an Acura RSX transmission, servicing a Civic Si gearbox, or refreshing the differential in a K-series-powered Honda, this genuine Honda OEM Differential Ring Gear Bolt is an excellent choice for maintaining factory-quality drivetrain hardware.

Installation Notes
- Proper differential ring gear bolt installation is critical for transmission reliability and drivetrain safety.
- Before installation, inspect the differential assembly, ring gear mounting surfaces, and threaded holes for damage, contamination, or debris.
- Confirm that the replacement bolts match the original fasteners and are compatible with the differential being installed.
- Position the ring gear correctly against the differential mounting flange and align all mounting holes.
- Install the new Honda OEM bolts by hand initially to prevent cross-threading.
- Always follow the factory service manual for the correct tightening sequence, torque specifications, and thread preparation requirements.
- Use a calibrated torque wrench and follow any specified torque-angle procedure. Do not reuse torque-to-yield hardware when the applicable service instructions require replacement.
- For aftermarket differential installations, follow the differential manufacturer's instructions regarding bolt design, thread-locking compound, and tightening specifications.
- After assembly, verify that the ring gear is properly seated and that the differential operates correctly before completing transmission installation.
