POLARIS PRO R / SLINGSHOT ADJUSTABLE CAM GEARS
Machined from hardened steel alloy and fully compatible with the stock Pro R timing chain, these are the perfect way to gain top end or low end torque depending on how you dial in the gear settings. Widen the lobe separation for more top end, smoother idle, less valve overlap if running boost. Go the other way for a tighter center for better bottom end torque and mid-range gains, enhanced lope at idle. Allows for 5 degrees of advance or retard for both intake and exhaust cams with easy to read indicator marks on hard anodized gold center sections. Includes 4 x ARP stainless steel clamping bolts for added peace of mind. Fits all Polaris Pro R and SlingShot engine platforms.
