HRSS RAMPS WEIGHTS & TEAM TSS04 CLUTCH

The Hot Rod Sled Shop Inc. HRSS2 custom ramp is a new ramp we've developed that fills another void in oem ramp design. It is designed with a lower engagement notch and lower starting height for reduced initial rpm while still loading the motor and not building rpm too quickly. It has a less aggressive start than our HRSS1 or 414 ramp. It allows the use of primary springs of 160lbs.- 200 lbs. start force or greater without the aggressive grab and rpm. This helps prevent track spin, reduces belt slip , and of course belt and sheave heat. We also made the tip profile approximately .020" taller than the HRSS1 ramp. This places the tip profile right between a stock 414 and the HRSS1 ramp. the HRSS2 ramp also works really well with oversize rollers by reducing the "buzzy" feel of let's say a 414 for comparison at mid rpm (which really is increased rpm at mid throttle positions of 5000-6800 rpm). The taller tip profile helps maintain full shift rpm with the additional tip weight that oversize rollers create. We have tested these extensively with stock to 2mm oversize rollers with great success. Check out the comparison pics with 414 back, HRSS2 center and HRSS1 front. Please call for setup information or tech questions as we are glad to help.

Hot Rod Sled Shop Ski-doo PDrive Adjustable weights available 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 heat treated steel. We then use Igus I-glide German made bushings for almost 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 compressed spring rate in most cases from stock weights. The PDM weights will easily load a 300 hp motor with a 250pound compressed primary spring. The Ski-doo HRSS- PDM2 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 applications.. 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 850 Summit, and 850 MXZ applications, 850 BIG BORE applications, 850 R applications, as well as 900 ACE Turbo & Turbo R 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 high elevation and SUMMIT models as well as MXZ 600R. Our SUmmit kit is spot-on offering 5-10 mph 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 slows 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. HRSS-PDM2 series weights 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. 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 HRSS-PDL2 with a weight from 62-73 grams was designed for high altitude applications and has the same shift curve as our PDM2. 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 apllicatios. 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 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. All of our weights sets include 3 weights and also include a set of epoxy magnets for adjusting weight and are either nickel plated or Black Oxy coated to prevent corrosion. Please note the black oxy penetrates into the steel even though the outer "black" coating scratches off!

HOT ROD SLED SHOP PDM2 ADJUSTABLE WEIGHTS FOR POLARIS. THESE ARE HRSS REPLACEMENT WEIGHTS FOR POLARIS 10 AND 11 SERIES WEIGHTS. THIS IS OUR ROCKETFIRE CLUTCH WEIGHT PROFILE WHICH IS LOWER FROM HALF SHIFT TO FULL SHIFT THAN A POLARIS 10 SERIES WEIGHT. THIS LOADS THE MOTOR LOWERING RPM BY 250 RPM THAN AN EQUIVALENT 10 SERIES WEIGHT. tHIS CREATES MORE MPH AND TRACK HORSEPOWER IN MOST APPLICATIONS. IT HAS WORKED REALLY WELL ON THE NEW 650, 800, & 850 POLARIS MODELS IN BOTH LOW AND HIGH ELEVATIONS. WE HAVE A UNIQUE SHIFT CURVE SIMILAR TO OUR FAMOUS SKI-DOO PDM2 CURVE THAT IS NOW APPLIED TO POLARIS CLUTCHING. WE HAVE BEEN ABLE TO ACHIEVE MORE TRACK HORSEPOWER THAN 10 SERIES PROFILE WHICH IS WHAT ALMOST EVERY COPYCAT WEIGHT OUT THERE REALLY IS. OUR WEIGHTS WILL ADJUST FROM 64-80 GRAMS IN ONE GRAM INCREMENTS. OUR PDM WEIGHTS LOAD HARDER AT FULL SHIFT SO YOU NEED TO RUN MORE PRIMARY SPRING FORCE AT FULL SHIFT TO KEEP THE RPMS UP. SOLD PER SET WITH RARE EARTH MAGNETS.
