Customers say

Customers highly praise the product for its ease of installation, adjustability, and compactness, allowing for more clearance. They emphasize its strength and high cranking power despite its lightweight. The starter fits perfectly in various models, including 57 Chevy 350, ZZ4 crate motor, small block 383 stroker, and more. Some experienced increased starting speeds after installation. One downside noted was a slightly tough to understand wiring diagram. A few reviewers had issues with gear wobbling leading to premature wear but this was not common. Many customers would purchase again due to its efficiency, reliability, and value for money. It's compared as superior to rivals, notably MSD Dynaforce.
