We had our rear shocks replaced and now the jeep bounces like a 70s Cadillac. We have a 2" RC lift and the old shocks where fine. The dealer says the shocks are being stretched and that is the reason for the bounce. They are using Mopar shocks #52090247.

Are these the right shocks?

@Beeks;

I don't know that I agree with the Dealers diagnosis;

However, you might consider replacing your rear shocks with some version of the Bilstein 5100's;

Just make sure they are longer than the stock shocks, so that they allow the rear axle to travel when necessary.

If your rear shocks are the originals from the factory and haven't been replaced yet, you're definitely overdue to replace them with how many miles you have on your XK.

Thanks of the reply. I'm resisting trying to pay for the shocks as they are under warranty (lifetime plan). One had been replaced about a year ago (again under warranty) and it was fine. Now it's bouncing all over the place with two new MOPAR shocks. Does the RC lift stretch them? That's what they are saying.

The RC lift could potentially be maxing out the extension of those stock shocks, meaning that the rear axle is not being allowed it's full range of travel when hitting bumps or dips - the limiting factor being the length of the stock rear shocks.

I don't know if that would cause the bouncing you're describing though.

I chatted with RC and they said the lift does not change the geometry of the suspension. Also the dealer said they would try another set of shocks on the back end. I'll let you know how it goes.

Sounds like a plan, I'll be interested to hear which shocks you actually decide on.

Took it back to the dealer. They replaced the shocks with the same Chrysler parts and that seems to have fixed the issue. Turns out both shocks were bad. :unsure:
