Adjustable Armstrong Damper Valve (Each) MGA MGB MGC+MIDGET+Z/ZB - new product

Factory fitment on many classic MGs, Armstrong lever shock absorbers provide their function by cycling oil back and forth via internal porting to a bi-directional relief valve. The valve which screws into the body of the damper uses springs for bump and rebound control these being specific to their application. Today owners wishing to alter the operation of their original dampers (typically for competition purposes) can either replace the valves with an alternative assembled with 25% stiffer springs and/or change the weight of the oil from standard road SAE20 to heavier SAE30 viscosity for increased stiffness. Provides in situ rebound adjustment (from soft to hard) using the original damper making them ideal for competition use. Designed to convert standard Armstrong lever dampers in a similar fashion to the Roadholder lever dampers available from Armstrong in the 1960s. Suitable for MGAs, MGBs, MGCs and Midgets, installation requires removal of the damper, draining/refilling of oil and priming. Features include; Wide range of adjustment (more than adjustable telescopic dampers), Straightforward on-car adjustment via 8mm hex, Manufactured in the UK, Retains the original look, No external pipework, Proven in competition, Recommended for use with mineral or synthetic SAE 20 oil.
