Re: Coil Spacers?
I just put coil spacers on my H2. I took it offroading last week and had no problems. I used Supermaxx torsion keys and coil spacers. It added 1.5 inches. I bought them from Trail Duty. You can see the results on in the photo section of this site. The heading is 2003 H2 with 40x13.50x18's. Here is there link.

Re: Coil Spacers?
those look reat and i really wish i would have seen the supermaxx torsion keys before i bought the readylift set. i have had no problems out of them but i know they dont have the versatility of 3 inch lift. so before i click the buy button did you need to change shocks or can you still use stock?
Thanks
Bentley

Re: Coil Spacers?
If you look on Supermaxx web site and download the instruction, I think they recommend not changing your shocks. I did not change mine, and so far no problems.

Re: Coil Spacers?
Why spend $250 on TB keys when can can use GM/Chevy 1/2 ton keys for $60 that do the same thing?
You can go up to 1.5" rear spacer on H2 coil spring suspension without issue.
To get the most out of your front suspension, you should use the longer Cognito-Bilstein shocks.
There is also a set of Bilsteins for the rear that allow you to get 2" more travel. Works great with the coil spacers.
If you guys are careful in your product selection- you can add more travel/flex in the front & rear on the H2, raise the height several inches, strengthen the weak OEM steering components and keep a relatively low center of gravity

Re: Coil Spacers?
I got my TB Keys over a year ago, so I already made that mistake. I am getting the spacers within the week and I have not decided what shocks to do yet. I have been looking at the Rancho RS9000XL's. I like the adjustability on them and I can pick them up for 250. Can argue to much with that.
