Our Process and Quality Assurance

We take pride in our precision rebuilding process, utilizing advanced equipment like computer-controlled indexing machines and vulcanizing tools to ensure accuracy. This process includes thorough cleaning, inspection, and high-strength silicone injection, leading to improved stability and performance. Our rebuilt dampers use cross-linked carbon rubber for superior durability compared to aftermarket alternatives, meeting or exceeding OEM standards. We are committed to providing quality, even if that means we might not always be the cheapest option.

The Importance of Harmonic Balancers

Harmonic balancers play a crucial role in maintaining your engine’s health. When not functioning properly, they can cause vibrations that may lead to serious damage. Our customers have shared stories of improved performance, reduced noise, and a smoother drive after installing our rebuilt harmonic balancers. One customer, restoring his 1963 Corvette, even credited our restored balancer with protecting his engine’s crankshaft from further damage. We are dedicated to preserving your engine’s performance and longevity through expert craftsmanship and high-quality materials.
