- Precision machined grooves, tightly sync with all OEM and aftermarket belts.
- The PERRIN crank pulley is machined from 6061T6 billet aluminum, anodized black or red and laser etched for increased belt life and a precision fit.
- Gates Micro-V Stretch Fit Belt
- Gates stretch fit belts may look like standard V-ribbed belts but inside they are dramatically different. The secret is Gates new TwistLock Technology where the strength and flexibility of advanced polyamide tensile cord is surrounded by a specially formulated adhesive that literally locks on to the cord - allowing the cord to elongate and stretch but never lose tension.
