looking to convert my gpx to polaris hydro brakes,can i use my splined brake rotor? or do i need a keyed shaft and brake disc from an exciter?
 

thanks Mike,wasn't sure.all the conversions i saw were on EX'S and Srx's with the keyed rotor.are you racing ovals this year?
 
i will run a few places but for the most part i will have a driver for the sleds ...old 338 gpx oval sled was retired this spring so i may put the engine in the 433 chassis which was last run at ER in 2013 ..... may also pull out the old SS 440 which has not been out since 2011 also have the SSR clone and 92 "Mutt" Phazer
