$380/ add shipping.

SamCo rear coil springs for the rear of an H2 provide approximately 1/2" to 1" of lift for the rear of your H2 Hummer, compared to the factory rear coil springs. They also provide the potential for more wheel travel, as they were designed for pre runners and race H2's. The springs have a 2.5" longer free length, but less spring rate than the factory springs to provide a ride quality similar to the factory air bag suspension. The additional free length would allow for about 20% more wheel travel with the use of longer shocks and refabricated shock mounts. Sold in pairs.

Cool option, but they seem awfully expensive versus stock as they only provide for .5 to 1" of lift and only allow 20% more flex when the vehicle is fitted with longer shocks/new shock mounts.

I replaced my airbags and now my Service Air Suspension warning won't go away. Anyone find a permanent solution to this? I've already tried removing the fuse in the front left wheel well.

Yep, depending on teh year, you either need a new pcm OR they reflash for 3 issues. I'll get you list when I get mine done. The Castlerock HUMMER dealer is going to do mine. 06 gets re-flashed.

Edit: Did you remove your bags for springs ? I have been reading through your post here and am a little confused. This post says you replaced your air bags, http://www.elcovaforums.com/forums/s...t=38979&page=2 to me that means you had new air bags installed but I guess it could mean you replaced them with coil springs (sorry, I am a little slow on reading between the lines) . But, I went over to the "other" site you said that you put springs in, if that is the case, try unplugging the compressor control module in pic below, remove the relay completly under the fenderwell and disconnect the battery, the light should go out.

P.S. Nice looking truck from what I've seen at the other site.

Easy Ed thanks for keeping me in line. I actually posted and forgot to check to see if anyone replied. I don't see a picture in your post? My truck is a 2003. Thanks for the compliment on the looks. You should see it with my boat

My bad, I posted the wrong link, duh.

Try looking at the pic at the bottom of this post http://www.elcovaforums.com/forums/s...ad.php?t=38543

I will also edit my other one with the bad link/no pic. Edit: won't let me edit my own post ??

Good luck, Ed
