Overrun Brake Damper AL-KO 161S, 161R (up to 12/88), 42.5 mm bush

Product detailed description

Overrun brake damper for AL-KO 161S and 161R overrun devices (version up to 12/1988) with 42.5 mm bush is designed to ensure smooth and safe trailer braking. It is a hydraulic (gas-oil) damper that controls the movement of the drawtube during braking and release. This reduces shocks between the towing vehicle and the trailer, improves driving comfort and decreases stress on individual braking components.

The damper is compatible with AL-KO 161S and 161R overrun brakes manufactured up to December 1988. It corresponds to older versions of these units and serves as a replacement for worn or defective original parts. A properly functioning damper is essential for smooth brake force distribution and safe trailer operation.

Technical specification:

• suitable for AL-KO 161S / 161R (up to 12/1988)
• bush diameter: 42.5 mm
• damper body diameter approx. 24 mm
• double-acting hydraulic damper (effective in compression and extension)
• installation inside the overrun brake housing (internal mounting in the drawtube)

The damper works by controlling the movement of the overrun mechanism during braking. When the towing vehicle brakes, the trailer pushes against the coupling; the damper slows this movement and ensures smooth transfer of braking force to the trailer wheels. It also dampens the return movement when starting off, eliminating unwanted jolts.

Replacement is recommended in case of reduced damping effect, excessive overrun travel or irregular braking. Using the correct type according to the overrun device designation and bush diameter is essential for proper installation and function. This damper provides a reliable solution for repair and maintenance of older AL-KO 161S and 161R overrun brakes and contributes to safe and comfortable trailer operation.
