Ski-Doo TRA replacement Primary clutch
For Ski Doo 670, 670HO, 670 SUMMITS models only please see application below, please specify exact year, make, model, including track length and elevation in notes if purchasing.
One thing to consider in purchasing this clutch, your stock used TRA is probably worth $250-350 on Ebay, off setting the cost of this clutch and making cheaper than the average rebuild cost of a TRA clutch.
2 year Warranty / rated and tested to 320HP / Precision Balanced
Electric Start compatible, just bolt your stock ring gear onto this clutch.
4 lbs lighter than a TRA clutch (13.3lbs vs 9.4lbs) / Center of mass is considerably closer to the motor and the centerline of the crankshaft. This provides superior throttle response, faster revving, allowing for lower engagement without hesitation and resulting in better applied traction.
Used exclusively by MCB on all their personal and shop sleds
Considerably smoother than any other clutch we have ever used.
More torque sensing than an OEM clutch. Senses track spin and overall track load and makes seem less adjustments, holding constant RPM. Low end sensing has an almost traction control like feeling.
Excellent deep snow, take off and load sensing!
Considerably less sensitive to snow conditions than an OEM clutch!
Easily tuned. Weights can be changed trail side with a 36mm socket and the holding tool (sold separately). The face cover plate is not under any spring load, this allows weight changes to be made in minutes with a flat bladed screwdriver. The spring cup / retention design is identical to a Ski Doo design with the addition of a much better spring and spring cup guide tower for easy assembly.
Uses the same puller as your stock clutch (applies to Ski Doo only)!
Don’t be fooled by the looks of this clutch, very simple, yet the most effective clutch we ever used or tested! 50% less moving parts as compared to OEM Ski Doo. No Ramps. no rollers, no thrust washers, No arms. Weight adjustable sliding blocks have constant leverage at all shift points / speeds as compared to the exponential leverage loss OEM designs! Simply the best, most durable easily tunable clutch we have used or tested in our 26 years of business and 40 years of snowmobiling!
