Bushings; rubber, poly, & delrin
We carry lots of parts for different year models of Corvettes, but all of them need a bushing or two along the way. Depending on how and where you drive your Vette is typically the determining factor for choosing your flavor of bushings. We’ll cover how we use them in our assemblies and when we recommend them for you when rebuilding your parts.
Rubber, polyurethane, and Delrin are all materials used for making control arm bushings, which are components of a vehicle’s suspension system. The key differences between them are their durability, stiffness, and resistance to wear and tear.
Rubber bushings are the most common type of bushing used in vehicle suspensions. They are inexpensive and provide a comfortable ride because of their ability to absorb shocks and vibrations. However, they tend to wear out relatively quickly and may deteriorate over time, especially if exposed to high temperatures or chemicals. We only have these available for 63-82 Corvettes.
Polyurethane bushings are an alternative to rubber bushings. They are stiffer and more durable than rubber, which improves handling and reduces flex in the suspension. Polyurethane bushings also last longer than rubber and are more resistant to wear and tear. However, they can be more expensive than rubber and may produce more slightly more road noise and vibration in the vehicle. We have these available for 63-96 Corvettes.
Delrin bushings are a type of thermoplastic bushing that is highly durable and resistant to wear and tear. They are much stiffer than rubber or polyurethane bushings, which improves handling and reduces flex in the suspension. Delrin bushings are also less susceptible to changes in temperature and are less likely to squeak or produce noise. However, they can be more expensive than both rubber and polyurethane bushings. These are available on our 63-82 front coilover kits and 1984-2019 Corvettes.
