I have an 08 H3 with 20s. The thing bounces all over the place. Are there aftermarket shocks that will handle the added weight of the larger wheels?
Any other recommendations?

 

P.S. Im aware that there is a ride quality difference because of the lower profile tire. This thing is bouncing all over the place. Thanks all!

 

I've upgraded to 20's on my other car with no problems other than a firmer ride. It could be the brand of tire or the air pressure.

Before diving into shock replacement, also check your swaybar bushings for wear too.

 

^^^^ What he said. Mine has been lowered on 24"s. Rides the same as it did before. No bounce at all.

 

Have you done anything else to it besides the tires & rims. sometimes when the front is raised to level it out people have had conditions like you describe, most add cognito front shocks & trailduty's longer bump stops. also what psi are your tires at?

 

As you lower the profile of your tire the sidewalls becomes shorter. Nearly all the tire flex comes from the sidewall. When it is shorter it reduces sidewall flex, thus the ride becomes firmer...unless your a$$ is dead!

 

Bought it with the rims on it. As far as I can tell there are no aftermarket alterations to the susspention. The tire pressure is 36-38 in rear and 34-35 up front. I am used to driving lowered cars so I understand there will be a stiller ride with the shorter side wall of the tires but this thing really bounces all over the place I.E. bad bump steer and rear bouncing alot. I am under the impression that heavier wheel/ tire combo needs a heavier shock to handle the added weight.
I'll get under it today and take a look at the end links and post back
Thanks

 

Don't forget to look for leaking shocks too, maybe one or more have failed. Otherwise:

The only suspension difference between standard and Adventure are the front and rear shock absorber part numbers. The springs remain the same between the two. It seems like the factory tweaked shock absorber specification to account for just the heavier 285 tires.

I guess the question when running an even heavier wheel/tire combo is how much more shock do you really need and what brand/model to choose to get there?

 

Most of the larger aftermarket wheels are very heavy. They may look cool but the extra weight is what auto enthusiasts call unsprung weight. To improve your car's handling also consider stiffer sway bars for flatter cornering and adjustable shock absorber that you can fine-tune to your liking.
