It includes a coupling damper, rubber bellows, and a secondary coupling cable. The damper has a total length of 530mm and a body length of 370mm, suitable for trailers ranging from 1500kg to 2600kg. The bellows have hole sizes of 45mm and 60mm diameter, with an approximate natural length of 130mm. The secondary coupling is 1m long and features high visibility yellow with a thicker 3mm cable for extra strength. This kit is ideal for refreshing your trailer's braked coupling and fits trailers with a standard 50mm tow ball coupling. It is not compatible with trailers using towing ring or nato ring couplings. While efforts have been made to ensure part accuracy, it is essential to verify that all parts are identical to the original ones before fitting, as trailer parts can vary.
This guide helps owners of trailers with ALKO 251S braked couplings maintain and service their hitches using the AB Tools service kit. The key benefit is restoring the smooth and safe operation of your trailer's braking system. A crucial caveat is ensuring the replacement parts match the originals exactly, as variations exist. This kit includes a coupling damper, rubber bellows, and a secondary coupling cable, designed for trailers with a 50mm tow ball coupling and a weight capacity between 1500kg and 2600kg.
