Finally here! Slipper delete for the Serpent SRX2 line it is design for stock 17.5 racing buggies. The design is easily the lightest delete kit on the market , the complete assembly with exotek top shaft(not included) weighs under 9G! to put that in persepective the stock steel top shaft is 10.2g by itself. This is a huge amount of static weight loss and rotational mass loss. This allows the car to accelerate quicker, brake faster and run cooler all of which you need for stock racing. Kit comes with Spur, Adapter, draw screw, lock nut and screw for the adapter. The design also allows you to use stock spur gears by using the adapter itself as a drill jig and you simply just drill 3 1.5 holes in the stock spur gear and screw together, the "ring" on the adapter centers the spur gear! The design also allows you to use stock spur gears by using the adapter itself as a drill jig and you simply just drill 3 1.5 holes in the stock spur gear and screw together, the "ring" on the adapter centers the spur gear!
