About this product

TRIALLI shock absorber (AG 18052) restores factory damping characteristics by controlling spring oscillation on both compression and rebound strokes, recovering steering precision and reducing body roll. Damping configuration — Fitting Position: Front Axle, Shock Absorber Type: Aluminium, Shock Absorber Design: Aluminium, Shock Absorber System: Aluminium — is tuned to the original suspension geometry so spring rates and ride height are unaffected, preserving the manufacturer's comfort and handling balance. Mounting dimensions, piston diameter, and stroke length replicate the OEM unit on AUDI applications, allowing a straight-swap installation without drilling or bracket modification. Supersedes manufacturer part numbers: 060584GB, 1142107500, 1142107509, 1266250004 and 55 more. TRIALLI dampers are gas-pressure charged, zero-leakage tested on a servo-hydraulic rig, and carry a 2-year unlimited-mileage warranty against manufacturing defects. Shock absorbers gradually lose damping force over time and should be inspected at 50,000 miles and replaced by 80,000–100,000 miles — even if they are not visibly leaking, internal valve wear reduces their effectiveness. Warning signs include excessive body roll in corners, nose-dive under braking, rear-end squat during acceleration, uneven tyre wear, and a bouncy or floaty ride — a simple bounce test (push down on each corner and release) can reveal weak dampers. Shock absorber replacement is an intermediate DIY task that requires spring compressors (for strut-type assemblies), a torque wrench, and penetrating oil for corroded fasteners — allow 2–3 hours per axle. When selecting shock absorbers, match the damper type (twin-tube, monotube, or gas-pressurised) to the original specification — upgrading to a different type can alter ride height and handling characteristics. Always replace shock absorbers in pairs (both sides of the same axle) to maintain balanced handling, and have the wheel alignment checked afterwards — worn dampers often allow geometry to drift out of specification. Every part is dispatched with tracked delivery and a 14-day money-back guarantee with hassle-free returns.
