Product Details
The Honda OEM Rear Suspension Trailing Arm Bolt is a genuine factory replacement designed to secure the rear suspension trailing arm and associated suspension components on compatible Honda and Acura vehicles. This essential suspension fastener helps maintain proper suspension positioning, alignment, and secure attachment during everyday driving.
Featuring a 12mm diameter, 68mm length, and M12 x 1.5 thread pitch, this genuine Honda bolt is manufactured to original equipment specifications for dependable performance and factory-correct fitment.
Commonly used on the 2002–2006 Acura RSX, 2001–2005 Honda Civic, and select Honda Accord applications, this OEM suspension bolt is an excellent replacement for damaged, seized, corroded, or missing original hardware.
Rear suspension mounting bolts are frequently exposed to moisture, road debris, and corrosion. Over time, the original bolt can seize inside the suspension bushing sleeve, making removal difficult during shock absorber replacement, suspension upgrades, or routine maintenance.
Whether you're replacing worn rear shocks, installing coilovers, rebuilding the rear suspension, or restoring factory suspension hardware, this genuine Honda OEM Trailing Arm Bolt provides the correct replacement hardware for compatible applications.

Installation Notes
- Proper rear suspension bolt installation is essential for safe suspension operation and dependable handling.
- Before installation, inspect the trailing arm, suspension bushings, mounting brackets, and surrounding components for damage or corrosion.
- Confirm that the replacement bolt matches the original fastener and is compatible with your specific suspension mounting location.
- Seized Suspension Bolts: On older Honda and Acura vehicles, the original bolt may become seized inside the metal sleeve of the suspension bushing. Penetrating oil, appropriate removal tools, or cutting the original bolt may be necessary during disassembly.
- If the original bolt must be cut or forcibly removed, inspect the suspension bushing and mounting bracket for damage before installing the replacement hardware.
- Carefully position the suspension components and install the new Honda OEM bolt without cross-threading.
- Always follow the factory service manual for the correct tightening sequence and torque specifications for your vehicle.
- For suspension mounting locations that use bonded rubber bushings, perform final tightening at the specified suspension ride-height position to prevent unnecessary bushing preload.
- After installation, verify that all suspension hardware is properly tightened and that the components move through their intended range without interference.
- A professional wheel alignment is recommended after suspension repairs that affect rear suspension geometry.
Note:
- Includes one genuine Honda 12x68mm Rear Suspension Trailing Arm Bolt. Mounting nuts, suspension bushings, trailing arms, shock absorbers, coilovers, and additional hardware are sold separately unless otherwise specified.
For Honda and Acura enthusiasts replacing seized rear suspension hardware, installing upgraded suspension components, or restoring factory mounting hardware, this genuine Honda OEM Trailing Arm Bolt provides the correct factory dimensions and dependable construction needed for a secure suspension installation.

2001 Honda civic. The original bolts were seized in the bushings and had to cut them off. These bolts are OEM and fit perfectly. Great product and great price!

This part almost always breaks when you replace rear struts as it often rusts in place and either is stripped as you remove it or you have to cut the rear strut off to remove it. This replacement fits perfectly. Do yourself a favor. Just buy these before you replace your struts. Saves you time :)

Couldn't ask for anything different, quick service for a bolt that had seized up on me and needed to be cut out. Genuine Honda part in Honda packaging. Thank you!
