Factory leaf spring and shackles utilize a soft rubber bushing to mount the spring to the frame. The rubber is great for reducing the noise and vibrations from being transferred into the cab. Unfortunately, rubber bushings have a short lifespan. Once the rubber fails, due to wear and tear or road grime, a leaf spring's effectiveness is severely reduced. Meaning you will experience a very bumpy ride, the vehicle's ability to carry a load or tow is hindered greatly and you'll experience a loss of control.
Br>Daystar's leaf spring and shackle bushings are made of high-quality polyurethane. Resistant to wear and UV rays, polyurethane is a much better-suited material for leaf spring bushings than rubber. Help your vehicle's load carrying capacity and towing ability with Daystar's polyurethane leaf spring and shackle bushings.
