The established construction of the H.A.R.M. Racing shocks has been transferred to these Big-Bore shocks.

The Big-Bore shocks are equipped with double leaded opposed piston a very precise screwing of the piston plate as well as a very good lower sealing system adjustable through distance discs.

The very big inner diameter of 17 mm ensures maximum volume what guarantees constant damping behaviour.

The outer diameter of the Big-Bore shocks is 19,8 mm. All springs with the appropriate inner diameter made of H.A.R.M., Mecatech, Genius, TRF and other manufacturers can be used without problems.
