Instead of screwing the 2 stock outdrive cups to the plastic spool, which is known to come loose, this redesigned cup allows 1 long M3 screw to pass through the spool and is screwed directly into this threaded cup instead, for solid and reliable assembly holding. This includes 1 hard anodized 7075 alloy cup and M3x20 screw.

New super light alloy locked spur mount with titanium center bolt for our lightest spur locker yet. Excellent for stock buggy racing to reduce rotating mass and a lower cg. The complete set with optional spur gear shown weighs 9gr- the stock slipper set weighs 22.2grams! Uses a wider range of available spur gear sizes by Exotek and Kimbrough. Attaches right to the stock top...

Almost half the weight of the stock screw at 2.4gr (stock is 4.3gr), this titanium screw lightens your rotating mass and lowers your CG. Direct fit on the stock laydown top shaft and slipper.
