Stiffest Aftermarket Shocks

[StandoutAlpha]

What is the stiffest shock brand out there for the Hummer H3? I'm coming from driving a lowered stiffer sport car. I dislike all the soft and body roll on the Hummer H3. *I'm not doing any off-roading or towing so I can careless about the stiff or harse ride. I just want a stiffer ride on the H3. A stiffer ride also feels like I have more control of the car.

Typically the shocks for towing are the stiffest, also more sidewall more body roll.

I have a fairly stiff car with the electromagnetic shocks and my H2 on 37s and I personally find enjoyment in both, you get used to body roll and how to maintain control while pushing it with enough experience.

May also be helpful to replace swaybar bushings and end links to reduce roll and tighten everything back up.

On the H3, there are the standard shocks and the off road shocks, both from GM/AC Delco. The off road ones are stiffer. A better ride can be achieved with Bilstein 5100s. I added a leaf on the rear springs to help with the weight of off road equipment and the ride is measurably stiffer. Additionally, if you've got an I5 H3 you can put in the torsion bars from an Alpha and that may help as well.

Iwillnc has a good point in that lower profile tires will go a long way towards reducing body roll and achieving a stiffer ride.

I found a set of Rancho RS9000XL shocks that has a adjustable of 9 different damper modes I think that's the one to buy next.

The Fox 2.0 are rebuildable can make them as stiff as you want. Came across one seller that you got one free rebuild/set up after buying and trying it out. If you have a truck with big heavy tires lifted up in the air not going to be sports car. Stiff ride translates to more than just stiff get a lot of chattering on street bumps. Springs are the stiffness the shocks are for dampening

I know that the H3 is not a sport car but my 08 Alpha is cammed when I bought it and when I floor the pedal *wide open throttle* just for fun the rear goes down and front goes up. I don't like that especially I when I go on a roundabout ramp at higher than usual speed there is alot of body roll. I just want a straight flat stiff/firm ride/suspension if I can get it.

Right now I have Bilstein B8 5100 shocks in the front and I think the rears are still oem stock. Still to soft for me I need something more firmer and stiffer.

FIRST - You need to replace those rear shocks before you dive into anything serious.


Depending on miles the rear leafs could be worn out, I don’t have an H3 so the others may be a better help in that regard.

Everything with power is going to shove the front end up and the rear down to some degree, my SS sedan I mentioned earlier can lift the front end a lot even with the suspension on performance/track mode when I push the LS3 hard enough.

There’s only so much you can do with a truck suspension to keep it compliant. I would suggest some HD sway bar replacements if that’s a top priority.

I had the same issue until I replaced the rear springs with emu leaf springs. Stiffer than stock and diffenetly a huge difference over 100K miles leaf springs.
Now the front lifts up at WOT but the rear doesnt squat, which is good since Im no longer looking at the sky.

One of the stiffest shocks I've had the pleasure to try to date has got to be the Bilstien 4200 shocks. I mean buck board stiff lol! Rattle your teeth.
I agree though that it may be time to update rear leafs and sway bar / end links.
My humble opinion.... I'd rip it all out at this point and put in a higher rate pack. Maybe add a extra help spring and air bags.
