The McLeod RXT HD Twin Disc Clutch Kit is built for high-horsepower street and strip applications, delivering exceptional holding capacity without sacrificing everyday drivability. Rated for up to 1,300 horsepower, the RXT HD is designed for vehicles with superchargers, turbochargers, nitrous oxide, or other high-output engine combinations. Ceramic-lined twin clutch discs provide outstanding torque capacity, smooth engagement, and a moderate pedal effort, making it an excellent choice for enthusiasts who demand both street comfort and track-ready performance. Whether you're driving to the drag strip, making repeated quarter-mile passes, or heading home after a day at the track, the RXT HD delivers the durability and performance to handle the challenge. Available in multiple configurations, the system can be matched to your specific setup. Choose an adapter ring version that mounts to your compatible flywheel, or a complete clutch and dedicated flywheel package that includes a billet steel flywheel or a billet aluminum flywheel.
