To correct AOE, this modification is necessary before installing our sorbothane pad on a Recoil Shock cylinder head. Otherwise the piston will sit too far back in the gearbox, preventing the teeth from meshing properly and thereby reducing piston lifespan dramatically.

Please allow 7-10 working days.

Cylinder head and sorbo pad are not included.

You will either need to purchase a cylinder head from us or send us one to modify:
