Damper (shock absorber) for the suspension, controlling the motion of the spring to keep the wheel in contact with the road.

The damper resists and dissipates the energy of suspension movement, damping the oscillation of the spring after the wheel meets a bump or dip. This controls body movement and maintains consistent tyre contact and ride stability.

Frequently asked questions

What does the 420412020AH damper do?
The 420412020AH is a BWI suspension damper, or shock absorber. It controls the motion of the spring by absorbing suspension energy, settling the spring after each bump so the wheel keeps firm contact with the road and the body stays stable.
How do I know if the 420412020AH damper has failed?
A failed 420412020AH damper usually shows as a bouncing or wallowing ride, clunking over bumps, longer stopping with nose-dive, scalloped tyre wear, or fluid on the damper body. Damping fades gradually as the internal seals and valving wear.
Do dampers need replacing on both sides of the axle?
Dampers are best replaced as an axle pair. Running a new 420412020AH opposite a worn unit gives unequal damping side to side, which affects handling, so fitting both sides of the axle together keeps the vehicle balanced.
