Double Adjustable Base Valve Shocks

Genesis Adjustable Instructions Sheet

The GXB3 is a mono - tube double adjustable base valve it's available in 5" - 6" - 7" - 8" and 9" stroke and any possible valving or split valving.

The GXB3 has a fully anodized aluminum body with a large built-on gas reservoir. This increases the volume of gas the shock will hold, which lowers the unwanted increase in rod pressure that comes with stroke. It also has a base valve that allows the shock to be effectively operated from zero to 300 PSI gauge pressure.


The GXB3 is completely rebuildable - revalvable.
