Frankensled’s Oil tank sleeve is designed to stop oil from seeping out of the oil cap due to warped reservoir necks and uneven sealing surfaces. The Oil Sleeve installs easily into place using a blow dryer or a heat gun. Our thick wall design creates a larger taper which makes for a smoother insertion, even on the most warped oil tanks. Fits: Polaris Edge,IQ, RMK, SKS, Switchback, Indy, Rush, Fusion, Evolved and Aggressive Chassis; Ski Doo XP, XR, Rev, ZX, CK, F and S chassis; Arctic Cat Crossfire, M-Series and Sno Pro Chassis. Fits all oil tanks with a 1.75” opening.
