Perfect for anyone looking to change gear ratios or beef up their rear end to handle the abuses of increased power on the street and at the track!! Upgrade your S197 rear end with our low friction rear end kit which includes specially micropolished and treated gears as well as treated bearings. Our rear end package greatly increases efficiency resulting in less horsepower lost to friction.

Many people focus on big blowers or turbos to make much more power than they really need to meet their goals. This results in extra stress on many expensive parts including the engine. At Weir Racing, our engineering and focus on quality and efficiency is what makes us competitive at record-breaking levels while maintaining maximum driveability and reliability. This kit was used on our  2013 TVS GT500 street car to set the world’s fastest TVS standing mile record at 218.6mph while maintaining full interior, air conditioning, power steering, GPS navigation and heated seats.
