The best 600 class sled ever made just got better with the addition of this 660 Big Bore Kit. This 660 Kit delivers an additional 15.7 horsepower and 7.6 ft/lbs of torque and reduces weight by 4.5 lbs on 2013-16 models (3.7 lbs on 2012 models). With snappy throttle response, this quick revving motor pulls hard throughout its power band, legging out well on top and beating most larger displacement stock sleds. From the moment you grab a handful of throttle you are sure to be impressed by the performance of this kit.

Requires cylinders, exhaust valve assemblies and stock head to be sent to SLP for modification.

*ERA 2014 Silencing Technology

NOTE: We recommend adding our Powder Valve™ for maximum performance in deep powder snow conditions.

Not for Axys Chassis
