HRSS TRA RAMPS, PDRIVE RAMPS, 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 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.

HRSS POLARIS P-22 ADJUSTABLE CLUTCH WEIGHTS FOR ALL 2022-23 POLARIS BOOST MODELS. THIS IS A STOCK PROFILE WEIGHT THAT ADJUSTS FROM 72-89 GRAMS WITH MAGNETS. THIS WILL ALLOW EASY TUNING FOR ECU FLASHES AND CLUTCHING CHANGES BY ADJUSTING THE FLYWEIGHT EASILY. THERE IS ALSO A NEW HRSS P22 WEIGHT COMING SOON WITH HRSS-PDM STYLE PROFILE AND FULL CLUTCH KITS!

HOT ROD SLED SHOP PDL2 RAMP SET:

ALL 3 OF OUR HRSS PDM SERIES WEIGHTS FEATURE:

*4130 CHROMOLY STEEL CONSTRUCTION * HEAT TREATED AND HARDENED * SAME CUSTOM HRSS SHIFT CURVE * 1.1 GRAM EPOXY COATED MAGNETS * IGUS I-GLIDE BUSHINGS * BLACK OXIDE COATED SURFACES

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 for 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, PDM2, & PDM2H all have the same shift curve. 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 apllications. 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 & 900 turbo trail or lake race 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! Regular price: $299.99

HOT ROD SLED SHOP PDM22 SERIES CLUTCH RAMPS FOR THE POLARIS P-22 DRIVE CLUTCH ON 850, 9R, AND 850 BOOST SLEDS. We have 2 versions with the same shift curve.

HRSS POLARIS PDM22 IS 72 - 89 GRAMS

HRSS POLARIS PDM22H IS 87-103 GRAMS

A new profile from HRSS aimed specifically at the POLARIS P-22 clutch on the 850, 850 Boost, and 900 motor. This curve has increased track horsepower on every sled we've put them on. For the tuners, a stock BOOST to Stage 2 pump gas flashes from HRSS can use the 72 gram base weights, anything more than 222 hp need our heavy weights. Our weights are machined from 4130 chromoly steel that is heat treated, and then Black Oxy treated 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 tstock components. Our shift curve is similar to the factory 14-76 & 78 weights in the first 1/2 of the shift but engages smoother yet is laid down more from 2/3rds shift to full shift. This tucks this weight a little more than any stock profile. It loads the motor harder from 1/2 shift to full shift. ECU Flash tunes of additional 20-60 horsepower are possible on the 850 BOOST with these weights. Sold in sets of 3 with best in the world IGUS bushings and epoxy coated magnets. Base weight on the PDM22 is 72 grams and adjusts to 89 grams. Base weight on the PDMH is 87 and adjusts to 103 grams. Our ramps are built with chrome-moly billet steel that is machined, hardened, and black oxy treated. 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!

NEW FOR 2024 HRSS PDM3 CLUTCH RAMP SET: 84 GRAM BASE WEIGHT: Hot Rod Sled Shop Ski-doo PDrive Adjustable PDM3 CLUTCH RAMPS were specifically designed for higher horsepower 850, 850 turbo and 900 turbo aplications. These have the same profile as the PDM2 weight but are a heavier base weight with a large amount of the weight concentrated toward the base keeping great backshift and throttle response. 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. Comes with 62 magnets … enough to fill the weights plus 2 extra. ALL OF OUR HRSS PDM SERIES WEIGHTS FEATURE:

*4130 CHROMOLY STEEL CONSTRUCTION * HEAT TREATED AND HARDENED * SAME CUSTOM HRSS SHIFT CURVE * 1.1 GRAM EPOXY COATED MAGNETS * IGUS I-GLIDE BUSHINGS * BLACK OXIDE COATED SURFACES
