Hasport Bushing Guide

U62A (Street) is best for most street applications and many road race applications. Stiffer than stock with the least noise, vibration and harmonics.

U70A (Race) is about the maximum needed for hard core road racing applications. It also works well for the occasional drag racer a long as you aren’t launching on slicks in a sub 11 second car.

U88A (Extreme Race) is very stiff for almost total control of the engine movement. If you are launching on slicks at the drag strip these will help you transfer more power by limiting engine movement. These will cause significant noise and vibration in the car chassis.

U94A (Most Extreme Race) is our stiffest urethane bushing without going to solid aluminum bushings. These bushing are red.

6061 (SOLID BILLET ALUMINUM) is for full out race cars only. The solid billet aluminum bushings has zero give.
