DRAG RACING NOTCHED ADJUSTABLE CLUTCH WEIGHTS 144-176 GRAMS

SPECIAL DRAG RACING NOTCHED CLUTCH WEIGHTS FOR PRO R MODELS WITH TURBO OR SUPERCHARGER INSTALLED AND A TWO-STEP LAUNCH CONTROL. 

144-176 GRAMS ADJUSTABLE

I RECOMMEND USING THESE WEIGHTS WITH A STARTING SPRING RATE OF 110 LBS OR HIGHER.  OUR 115-240 SILVER-WHITE SPRING WORKS VERY WELL WITH THESE.  IT IS ALSO ADVISED TO GET TWO OF OUR PRIMARY CLUTCH SPRING SPACER WASHERS SO YOU CAN ADJUST THE ENGAGEMENT RPM EVEN HIGHER IF NEEDED.  

3000-3800 RPM ENGAGEMENT WITH A 110+ LB START RATE SPRING

IF YOU ARE RUNNING HIGH BOOST 16+ PSI, YOU MAY NEED TO USE A FEW OF OUR TUNGSTEN SLUGS IN THESE WEIGHTS TO ADD ENOUGH MASS TO ACCOMMODATE THE HIGH POWER LEVELS. THE TUNGSTEN SLUGS ARE SOLD SEPARATELY ON OUR SITE. 

INCLUDES MAGNETS TO ADJUST MASS AND TWO ALIGNMENT WASHERS TO CORRECT CLUTCH ALIGNMENT IF NEEDED.
