Installation Notes

Proper rear shock mounting bolt installation is important for safe suspension operation and dependable handling.
Before installation, inspect the rear shock absorber mounting bushing, lower mounting bracket, and surrounding suspension components for damage, corrosion, or excessive wear.
Confirm that the replacement bolt matches the original fastener and is compatible with your specific suspension configuration.
Seized Suspension Bolts: On older Honda Civic models, the original rear shock mounting bolt may become seized due to corrosion. Penetrating oil and appropriate removal tools may be necessary during disassembly.
If the original bolt must be cut or forcibly removed, inspect the shock mounting bushing and threaded mounting point for damage before installing the replacement hardware.
Carefully align the rear shock absorber with its mounting location and install the new Honda OEM bolt by hand to prevent cross-threading.
Always follow the factory service manual for the correct tightening procedure and torque specifications for your specific vehicle.
For suspension mounting points that use bonded rubber bushings, follow Honda's specified suspension position during final tightening to prevent unnecessary bushing preload.
When installing aftermarket coilovers, verify that the factory Honda mounting bolt is compatible with the coilover manufacturer's lower mounting configuration.
After installation, verify that the rear shock absorber is properly positioned and all mounting hardware is securely tightened.
