What is better rubber or polyurethane bushings?

Ride Quality: Because rubber is softer than polyurethane, it’s much better at warding off road noise and vibrations. This means that rubber bushings make for a much smoother ride. They’re also a lot more prone to damage from oil, UV, road chemicals, and heat.

Do polyurethane bushings improve handling?

They will upgrade your handling, suspension stability, and have increased lifespan so they will be more favorable to folks that enjoy track car handling from their car or for heavy-duty and off-road vehicles, but they won’t do you any favors when it comes to vibration absorption.

What happens if you don’t grease polyurethane bushings?

There isn’t much that will degrade or otherwise harm polyurethane bushings, but enough friction on anything without the proper lubrication can damage it.

Do you need to grease polyurethane bushings?

Polyurethane bushing manufacturers advise to never use a petroleum based grease for poly bushing lubrication. Polyurethane should only be lubricated with one specific type of grease to insure long bushing life, and squeak-free performance, Silicone based synthetic water-proof grease.

Are polyurethane bushings bad?

Polyurethane bushings last much, much longer than rubber. Even without the stress of several hundred pounds of vehicle squeezing and smashing rubber bushings they are susceptible to vehicle chemicals, road salts, costal climates, and heat.

How long do polyurethane bushings last?

With proper care, polyurethane bushings can last the lifetime of the vehicle. The bushings will need to be re-greased every few years. Without proper lubrication, the bushings can wear, squeak, and bind. Some polyurethane bushings have a grease fitting.

Do you grease polyurethane bushings?

Can you over grease bushings?

Chassis/bearing greases(i.e. lithium soap-based greases) can quickly deteriorate rubber bushings. Of course there’s silicone-based/dielectric greases that are fine for use on or near rubber or poly bushings. Even polyurethane bushings should be lubricated with oil or petroleum based lubricants.

Can you lubricate bushings?

Answer: You can lubricate a squeaky bushing, but you need to be careful about the lubricant you use.

Why do polyurethane bushings need to be sealed?

It works great in a closed system like your engine where metal on metal parts are creating enormous amounts of friction and heat, but polyurethane bushings are not sealed and when your suspension travels whatever lubricant is between the bushing and the metal is going to be exposed to the elements.

How many bushings are in a universal polyurethane set?

Each set includes 4 bushings halves and 2 metal sleeves. These bushings have Kevlar weaved into a polyurethane blend to provide an even more durable performance bushing with incredible tensile strength while maintaining the comfort level of other aftermarket replacement bushings.

Can you replace rubber bushings with urethane?

It all has to do with the bushings on the inner pivots. SCCA Street Touring rules allow for alternate bushing material, so long as you don’t replace non-metallic components with metallic components. So you can replace rubber bushings with urethane or nylon or Delrin or some other non-metallic material.
