D3 LT4 Boost Pulley w.9.0 Boost Ring


Product Description

D3 Boost Pulleys are manufactured in the USA and are specifically engineered for the LT4 motor.  It is not a re-hash or generic fit pulley kit.

Weight has been drastically reduced by an amazing 4.5 lbs with which allows the pulley to spin freely and without restriction under load. D3 Harmonic Dampers offer the most precise and advanced execution of the proven elastomer-style harmonic damper (also called Torsional Vibration Damper) design. Most engine designers prefer elastomer-type dampers because of their durability, superior high-frequency damping qualities, and ability to dampen all types of vibrations: torsional, axial and radial. Other damper designs are limited to damping torsional vibrations only.

All D3 Pulley Kits are manufactured in the USA out of T-6061 billet aluminum and CNC Machined to MILSPEC tolerances for unparalleled quality.
