On my heckler yes, on my trance x no
I had an RP23 on my 2008 Heckler, waste of money as the Float R does does the same job as the RP23 minus the Pro Pedal…. all Santa Cruz air shocks come with a Low Compression tune so no need for the Pro Pedal.
When I sold my Heckler and upgraded to a Butcher I just went for the Float R, and the bike climbs pretty good with no need for Pro Pedal. With the Pro Pedal OFF the RP23 & Float perform identical.
All in all a great Air Shock!
