I installed Thuren's Fox 2.0 RR front 0.5" level kit on my '22 PW and loved the improvements. I immediately installed their rear Fox 2.0 shocks and stock-height spring kit, but I'm having the opposite effect - the rear-end ride characteristics are noticeably worse than stock.

At almost all speeds (especially over 50mph), the rear end never stops bouncing around unless the highway is absolutely perfect - it feels too soft. Could it be that this setup isn't ideal for 37s? Anyone have similar experiences? Looking for all options before reverting to the stock springs & shocks.

Could I possibly run their Fox 2.0 IFP rear shocks with the stock PW springs? The information on their site seems to say no, but it seems people are doing it?

FYI - All testing has been done with an empty bed. Improved ride quality is my ultimate goal. Running 37" Toyo Open Country ATs.

Thanks!

Have you replace the rear track bar with Thuren's?
It's been a very common issue with the rear suspension on these trucks

I don't think it's the rear track bar. I replaced mine with the Thuren kit and felt no difference. Nice track bar though.

I can't speak to the rear springs, I first used Icon rear springs. Absolutely loved the ride with those, but they weren't up to the task of handling the weight of my 4WC. I now have Carli rear springs, they are a bit stiff, but do the job.

For ride quality without the camper I would rate:
1. Icon
2. Stock spring
3. Carli

Hope you find what's causing this.

How many miles have you put on it? I installed fox 2.0s and within 500miles I blew 2 shocks out.

Thanks for the recommendations!

I've only put about 100 miles on the new setup. I'm not sure if these have a break-in period, so I'm planning to give it 1k miles before I revert to stock. Also planning to play around with rear tire pressures and may throw some weight in the rear to see how it impacts ride quality.

air pressure in the tires defiantly make a big change. I know Thuren tuned shocks are set up for their spring rates. if you want utilize the shocks you will need Thuren springs as well.

Tire psi? The rears should be significantly less than the front to get it to work right……unless you’re towing or loaded heavy then tire psi needs to come up.
