Custom Works Machined Outdrive Blades. This is a replacement for the Intimidator 7, Enforcer 7, Outlaw 3 and Rocket Stage 3 kits equipped with aluminum outdrives. Package includes two blades. This is the best blade Custom Works makes and will last multiple races provided you put a tad bit of diff lube on it prior to the race day. The blade type design allows the rear suspension to move easier while under constant drive from the motor making the car turn easier thru the centers of the corner and off. Blade type outdrives are suggested for all dirt oval racing using foam tires, mod to stock. Also they are suggested for loose dirt rubber tire cars provided the power of the class is 13.5 blinky or less.
