Power steering, aggressive wheel alignment geometry, wider wheels and lower profile tyres have all put radically increased loading on the steering systems of modern cars. Add to that engine bay contaminants such as oil leaks that also help to degrade the performance of steering rack mount bushings. Nolathane steering rack mounts are engineered to outlast and enhance steering precision and feedback.
Soft factory bushings whilst they do a good job of not transmitting engine vibration, they do create vague and unresponsiveness in the vehicles drive train. Under hard acceleration, the engine and transmission rotates, Nolathane engine mount bushings work in conjunction with the OE rubber bushing giving your car better throttle response as well as more crisp and defined gear shifts.
The 33mm front sway bar on my 2006 Chevy Colorado took 2 of us to pry it into place, but the 50% increase in stiffness keeps it on the road with more control. With the new Bilstein gas shocks all around I'm happy.
