Aftermarket Assassin P90X Secondary Springs for 2020+ Polaris RZR Pro XP / Turbo / Turbo S / Turbo R

Aftermarket Assassin P90X Secondary Springs for 2020+ Polaris RZR Pro XP / Turbo / Turbo S / Turbo R  

Springs serve as replacements for worn-out AA clutch kit springs or for tuners who have a specific preference for their chosen springs. However, unless proficient in advanced clutch tuning, we strongly advise against using any springs without our recommended clutch kit.

Gold/Green Spring 190-270: Stiffer than the OEM spring for more belt grip on the secondary
Gold/Blue Spring 190-295: One step stiffer than the gold/green and even better belt grip at full throttle
Yellow Spring 165-300: Great spring with less initial rate but a finish rate (full shift rate) high enough to keep belt grip
Red Spring 165-330: Very similar to the yellow but with a stiffer ending rate for those needing even more spring pressure at full shift
Light Blue Spring 170-350: One step stiffer than the red spring

Increased spring stiffness necessitates additional primary clutch weight, potentially resulting in a slowdown in shift responsiveness and a decrease in overall performance.
