This Straightline .040 Large Timing Key is a precision clutch component built for snowmobile drivetrains. At 0.040 inch thickness, it sets the timing clearance your clutch needs to engage smoothly and hold consistent shift points.

Sold individually, it measures 11 x 10 x 1 inches and weighs 0.5 lbs, so it is easy to keep a spare on hand for rebuilds and tuning sessions.
