Product Description

Hot Rod Sled Shop Ski-doo PDrive Adjustable weights for Ski-doo 600R ETEC, 850ETEC, 850 ETEC TURBO, and ACE 900 Turbo applications, and Arctic Cats with Team BOSS clutches are now available in 2 base weights and fully adjustable and tuneable to sleds with 300 hp. Our weights are machined from 4130 chromoly steel that is heat treated, and then electroless nickel plated for the the strongest and finest weight in the business. We then use I-glide German made bushings for zero bushing failures and a 25% closer tolerance on the axle for more precise weight travel as it goes through its cycles than the oem Ski-doo "shaker" style weights as we call them. Our weight eliminates the stock clicker system which we believe is a great benefit in even more precise tuning in exact shift locations than the Ski-doo OEM ramps. Our shift curve is different than any stock ramp. It loads the motor harder and then aggressively upshifts for quicker acceleration while maintaining good top mph with a lower full shift profile. Our ramps squeeze the belt harder, sooner and softer at engagement than the twitchy stock ramps. The PD series weights require more compressed spring pressure than your stock ramps - for you tuners you need a 50 pound stiffer spring. The PDM weights will easily load a 300 hp motor with a 250pound compressed primary spring. The NEW 2020 SERIES 2 profile is similar to a 968 in clicker #4 at engagement and then loads more than a 968 in clicker #1 at full shift. The HRSS-PDL2 with a weight from 62-73 grams was designed for REV GEN4 850 high altitude applications and the new Gen4 600R. We have reduced belt temps significantly with our weights in every application with more precise rpm control in more diverse conditions than the OEM style weights. The HRSS-PDM2 ramp with a weight from 73-92 grams works really well for low elevation application in both Summit, and MXZ applications as well as 900 ACE Turbo and Arctic Cat models. We have complete clutch kits available and kit reviews on DOOTALK.com have been stellar with superior performance over all other kits with both OEM weights and OEM style weights that are adjustable. Our HRSS PD2 series weights create a shift curve that puts more HP to the track than any of the oem style weights can.

Our PDL2 ramp has hundreds of hours testing on the Ski-doo 850 ETEC Turbo. Our kit is spot-on offering 10mph more track speed than the early release and brings the rpm down on the 2021 so it pulls much harder. Buy some tune-able ramps and clutch your own or try our kit. It's perfect for guys wanting more track speed, better backshift, cooler clutch temps, and consistent rpm. by the way you don't need a big weight with a fat belly to make your turbo fly- It just sows down backshift and has no advantage at all but everyobody needs something to sell ! Fluctutating RPM and over rev without a hard pull is the biggest complaint we hear and these PDL2 ramps allow you to tune that out of your turbo. Ramps or kits are available from HRSS online or at Star Valley Ski-doo, and Diamond S Mfg. in Utah.

Our Arctic Cat Boss weights offer super smooth engagement with the same famous aggressive ramp profile with quick upshift offering more track horsepower than conventional/ typical Arctic Cat weight profiles. We have a deeper final shift curve which creates more load and tack speed /mph at full shift. We offer 2 base weights with the lighter PDL 2best suited for 800 mountain sleds and high elevation, and the heavier PDM2 for 800 trail sleds. We will have complete clutch kits available soon.
