Massive Speed Adjustable Supercharger Tension System
When runnning smaller pullies, the stock belt will tend to be too large and “orbit” around the blower pulley resulting in lower boost levels and eventual belt failure.
This is the first idler system that’s truly adjustable, the pulley mount features a T slot so it can be moved effortlessly and infinitely. Mounting to the blower face also eliminates the spindly M6 bolts and long bracketry used on other’s designs. This system bolts directly to the snout and applies addtional pressure and removes slack from belt meaning repeatable, safe, BIG boost for you – far superior belt wrap than any other design. Billet aluminum constuction for good looks and light weight. Bracketry anodized Massive PURPLE so folks know you use the best, pulley in HARD COAT BLACK for long service life. All stainless hardware looks great and won’t corrode.
Massive’s exclusive idler features super high quality NSK DOUBLE BALL BEARINGS that will give years of trouble free service. Don’t be fooled by other’s low quality single bearing units.
