Features: Power Control Slipper Clutch: The big addition to the HPI Baja 5SC SS Limited Edition is the Power Control Slipper Clutch (PCSC). It uses three heavy duty clutch discs to absorb drivetrain jolts for extended drivetrain life and reduced maintenance. The PCSC also improves handling performance, just dial in the spring tension to track conditions for smooth and controllable launches. The amount of slip is easily adjustable using the included wrench and a new easy access gear cover. Included with the PCSC is a precision machined hardened steel 57T spur gear for maximum durability that rides on a ball bearing for long life. For custom looks, the aluminum outer plate is red anodized and laser etched with PCSC and HPI logos. Aluminum Tuned Pipe Set with Heavy Duty Steel Header: The HPI Baja 5SC SS Limited Edition includes a high flow aluminum tuned pipe with steel tubular header, which combine to make an ultra efficient tuned exhaust system that fits securely inside the roll cage.
