Unity Rear Shock Absorber Kit 2-257080-001

Unity Rear Shock Absorber Kit

The Unity 2-257080-001 kit supplies two nitrogen gas charged rear shock absorbers designed as direct OE replacements. It fits 2010-2015 GLK350 and 2013-2015 GLK250 models on the X204 chassis. The parts are built for trouble-free installation and long-lasting reliability on these specific vehicles.

Upgrading from worn original shocks

This kit replaces factory rear shocks that have lost damping control or developed leaks over time. The twin tube gas charged design restores ride quality and handling stability for the listed GLK models. The jump is worth it when the original units show excessive bounce, uneven tyre wear or fluid seepage.

Limits of twin tube gas charged design

Twin tube gas charged shocks provide reliable daily driving performance but lack the heat dissipation of mono tube units under extreme loads. They are not intended for heavy towing, aggressive off-road use or track applications where sustained high temperatures occur. The kit addresses standard suspension restoration only.
