Advice wanted on PolyUrethane bushings. As I replace worn out suspension parts, I want to upgrade to Polyurethane bushings. Any company/product you guys recommend?

 

@badicedog , many opinions on this topic.
(but if you wanted a ride like an old corvette, why not just buy a corvette, lol)

 

Some of the stock bushes allow a degree of twist, which rigid bushes don't, allowing the suspension to move in the intended arc. Whether polyurethane bushings are really an upgrade to the sophisticated bushes originally used is open to debate. Jaguar, especially in the days of Mike Cross, weree pretty good at suspension design so somewhat random changes can degrade the original good work done.

 

Prothane is one supplier.
They have a good selection of urethane bushings for Jaguars.

I have had problems with squeaking and creaking noises so have tended to stay with rubber or OEM bushings.
Especially on a quiet luxury car like a Jaguar.

I use Powerflex and have never had any squeeks or noise or failure.

 

Polyurethane bushing are great for the track, but a bit stiff for the street. So if you track your car, go for it, but otherwise you may grow tired of the ride.
Just IMHO.
Cheers.

 

thank you

 

I was told by a mechanic the poly bushings wear out very quickly.

 

Don't use that mechanic.
