Installation Position

Optimized Heavy-Duty Structural Design

1. High-pressure nitrogen sealed twin-tube structure: Balanced compression and rebound damping, reliable anti-fade performance during long highway and mountain driving
2. Seamless cold-drawn cylinder tube + hard chrome plated piston rod: Wear-resistant and rust-proof, effectively preventing hydraulic oil leakage under frequent suspension compression
3. Multi-layer fluorine rubber composite oil seal: Resists hydraulic oil erosion and high-low temperature aging to extend service life
4. Integrated PU impact buffer + textile reinforced dust boot: Blocks gravel scratches on the piston rod and eliminates metal collision noise at full suspension compression stroke
5. Galvanized anti-corrosion top base and bottom fork bracket: Guards against erosion from rain, snow and winter road salt
6. Complete one-piece shock strut assembly, supplied with standard installation hardware for direct replacement

Core Vehicle Handling & Riding Comfort Functions

1. Delivers consistent fixed damping force to balance soft smooth city cruising and rigid stable high-speed cornering handling for mid-size luxury sedans
2. Suppresses excessive spring rebound after hitting road bumps, eliminating continuous front-end floating shaking
3. Reduces front body tilt during sharp lane changes and turning, boosting vehicle road holding and driving safety
4. Filters harsh road vibration transmitted to the cabin and upgrades premium ride comfort of domestic FAW Audi A4L
5. Prevents irregular cupped front tire wear and extends tire service life
6. Maintains factory-standard vehicle ride height and avoids unilateral front suspension sinking caused by shock absorber failure

Common Solvable Vehicle Faults

• Front end bounces repeatedly multiple times after crossing speed bumps and potholes
• Obvious metal clunk knocking noise from front wheel arches on uneven roads
• Severe front body tilt and unstable steering during high-speed lane changes
• Visible oil stains and hydraulic leakage on the shock absorber cylinder outer wall
• Cupped scalloped uneven wear on front tire tread surfaces
• Obvious nose diving of the vehicle during heavy emergency braking

Brief Step-by-Step Installation Guide

Required Tools

1. Park vehicle on flat ground, lift front axle and secure firmly with jack stands, remove front wheel.
2. Use spring compressor to pre-compress front coil spring to release suspension tension.
3. Loosen top piston rod fixing nut and bottom fork axle bolts, take out the old shock strut assembly.
4. Thoroughly clean rust, brake dust and dirt on suspension mounting brackets and axle contact surfaces.
5. Install new 8W0413031M shock absorber, align top piston rod and bottom fork clamping position accurately.
6. Tighten all mounting fasteners to factory specified torque values.
7. Slowly release the spring compressor, reinstall front wheel and lower vehicle fully to the ground.
8. Manually press down front vehicle corners repeatedly for slow compression tests to check abnormal collision noise.
9. Complete low-speed road test to verify stable damping performance without bouncing or abnormal noise.
