Graziano L140 solutions

Drop Gear sets

Replacements are manufactured in a superior alloy, with optimised tooth counts and geometry that eliminate this failure point. These are offered in several ratios, depending on vehicle use, engine choice and desired MPH.

High Performance Clutch Kits

These clutch kits are produced in Kevlar, ceramic and carbon facings with lightweight aluminium pressure plate lids.  Custom flywheels made of high-quality steel or aluminium can be provided to suit any engine selection and are balanced as a rotating assembly with the clutch. Supporting applications from 300lb-ft to 2500lb-ft+.

Sequential Paddle Shift System
