KYB Shock Absorber - Front - 663500

The KYB 663500 is typically sold individually as a single shock absorber insert. For proper suspension balance and performance, it is highly recommended to replace them in pairs.

An oil pressure type shock absorber uses hydraulic fluid under pressure to control the suspension's damping. This generally offers consistent performance across a range of temperatures and driving conditions.

This specific part number (663500) is listed for the 316 E30 1.8 (83-88). While it's a 1.8L engine, it's essential to cross-reference with your exact E30 model year and specific OEM part number to ensure compatibility, as different E30 variants may have different suspension requirements.

This is a shock absorber insert, meaning it fits inside the existing strut housing. A complete strut assembly includes the housing, spring, and mount as one unit.

Symptoms include excessive bouncing after hitting bumps, a tendency for the vehicle to 'porpoise' on undulating roads, visible fluid leaks on the shock body, clunking noises, or a noticeable decrease in handling responsiveness.

The KYB 663500 replaces BMW OEM part numbers 1133224, 1133232, and 31321125150.

This could indicate an alignment issue. Ensure the vehicle undergoes a professional wheel alignment after the new shocks are installed.

Verify that all mounting hardware (top nut, pinch bolts) are securely tightened to the correct torque specifications. Check that no other suspension components are loose.

Confirm the correct part number was installed and that it is compatible with your specific vehicle model. Ensure the shocks were installed correctly and not damaged during the process.

Ensure the shock absorber was not damaged during installation and that no foreign debris entered the seal. Contact the supplier if a defect is suspected.
