Thunder Shift                                                                                                   Heavy Hitter

  • Get all the horsepower to the ground, fast & easy, no guesswork

  • You can't buy a better clutch kit for any amount of money!

The Thunder Shift and Heavy Hitter are the highest quality weight arms ever built!! The best engineering, materials, and production methods were employed in their manufacturing. Fasteners are made from billet stock (no hardware store parts are used). The weight arms and fasteners meet strict weight requirements.  Each set of weight arms are perfectly matched to a tenth of a gram.

The Thunder Shift and Heavy Hitter have routinely survived spin tests exceeding the RPM and stress limits of any clutch on the market without a single failure. Our testing as well as tests by leading magazines and tuners prove that where weight is placed has a dramatic effect of performance. TS/HH offer many weight combinations while being easy to tune to perfection. Gain two to five sled lengths. It works!!

Heavy Hitters
The Heavy Hitter clutch weight by Thunder Products, Inc. is the ultimate in high performance weights! The unique weight distribution is designed to "get the power to the ground". It is easily adjusted in low range without being removed from the clutch. It is also adjustable in mid range and top end with resolution as fine as 0.4 grams. The patented weight distribution system allows you to easily "dial in" a perfect shift pattern every time with no guesswork. The Heavy Hitter has undergone extensive field and dyno testing to insure total performance. The Heavy Hitter is an easy bolt on performance product that fits Arctic Cat, Polaris, Yamaha, or Comet clutches with special wide roller.
No clutch machining is required!

The Heavy Hitter is a bushed weight that is billet machined from the finest materials available, stress relieved, heat treated, and matte finished. Each set of weights comes perfectly gram weight match balanced. The Heavy Hitter weights have been spin tested at over 17,000 rpm's insuring the strength and durability required. Each set of Heavy Hitters comes with a complete set of tuning components and a tuning manual that is easy to understand and follow. NOTE: Heavy Hitter weights are available for sleds that normally run weights in the mid to high forty gram range up to seventy grams plus.

Thunder Products as well as its dealers and distributors continue to offer the finest full time technical support in the industry.
