2.5" External Bypass Coilover

Here we have our 2.5” External Bypass Coilover.  Our proprietary and patented design provides unparalleled performance and adjustability, with a bump stop, in one single shock.

Not only that, every single Compression and Rebound Zone is adjustable while on your car.  There are no valve shims to mess with whatsoever, simply turn the adjusters and dial in your car, easy as that. 

Our bypass shock does not use basic port holes, flapper check valves, or even valve shims of any kind.  We’ve got Externally Adjustable bypass tubes with Coil-Spring Check Valves just the same as any External Bypass Shock.  

We offer the 2.5” in two different configurations:  A 3-Valve Bypass and a 6-Valve Bypass.

The 3-Valve has two Compression Adjusters (one is the Bump Zone) and a single bypass adjuster for Rebound.  These were designed to be a simple and cost-effective upgrade to any car where a 2.5” shock is appropriate. 

The 6-Valve has three Compression Zones (one of them is the Bump Zone), two Rebound Zones, and a Free-Bleed Adjuster (works in both directions).  This is a more advanced solution that offers much more tuneablity and performance than the standard 3-Valve.
