Hot Rod Sled Shop HRSS8 Ramp for Improved and Prostock 700, 800 & 1000
This ramp for the Ski-doo Tra-2 clutches was designed for improved and prostock 700,800, & 1000 triple cylinder race application. This ramp design combines a ski-doo PX and 280 style ramp for a hard launch like a notched 280 for a tremendous holeshot yet loads the motor much harder from half shift to full shift. In the comparison pics you can see the lower belly and transition to tip than the 280 ramp. The tip profile is .015" taller than a PX. This ramp when tuned properly makes more mph than a 280 ramp setup. Track dyno testing at Pro-line as well as in field testing on grass and ice is showing good track horsepower gains over proven older setups. We have helix combos that work really well for many applications with these ramps. Customer feedback and testing suggests this blend of 280/PX style ramp is the ultimate big hp triple ramp set. Ramps are sold as a set of 3. PLEASE NOTE THAT WE NOW HAVE A TEAM TSS04 SECONDARY CLUTCH AND HELIX SETUP IN STOCK THAT WORKS REALLY WELL WITH OUR HRSS8 RAMP. THE 48-40/44-40 HELIX WITH A 160-260 IS A GREAT STARTING POINT FOR DRAG APPLICATIONS. THIS CLUTCH WILL FIT ANY SKI-DOO SPLINED JACKSHAFT. YOU CAN USE A CK3 OR ZX SPLINED JACKSHAFT IN F-CHASSIS OR CK3 CHASSIS APPLICATIONS.
