Before I put on the LP-15 Hellwig helper springs my 06 Colorado handled and had the ride pretty much like a car. The ride was good but it was a little to soft with more roll in turns than you would expect from a truck. When loaded, not real heavy mind you, it would sag more than one would expect for a half ton truck. With the Lp-15 springs it still has a good ride but it not as soft and has less roll in the curves and turns. They realy transformed the handling more than I expected, without making it a real hard uncomfortable ride. I like the springs adjustment feature also. Want more firmness tightened down the shackle a little more. With added weight the truck will remain pretty level. When you are through hauling the extra weight release pressure on the shackle bolts. I tightened mine a little more than the instructions said to enlist the help of the springs when riding empty to help with the softness and roll. Perfect!One note on installing the springs. It would have taken about 1 hour (BUT) the (unexpected) showed up. I didn't have to disconnect the brake cable which did help save time.I just bent the bracket just a shade to allow the front spring to slide under. Going good until I got to the aft spring. Could not install per the instructions due to the shock bolt hitting the shackle u-bolt. I tried turning the shock bolt around but the head was still to thick. Plus if it had worked I would have to remove the u-bolt when I replaced the shock. I loosened and moved the shock bolt back out of the way. Then I put the u-bolt in place with the bottom plate on it making sure the spring was touching the leaf spring so i could hold a nut up against the u bolt to mark it. I allowed another 1/4 in. to give room to install a 1/2 inch lock washer. I put two nuts on the u-bolt just past my mark and tighten them against each other to keep them from spinning. Then I used my 90 grinder with a cut off dics to cut the u-bolt. After the cut the nuts chased the threads when removed. Hack saw would work but the u-bolt is extremely hard. Before you start have a way to cut the u-bolt and two 1/2 in. lock washers. Note: Did not have to remove the tire. Jack up under the frame to just where the tire starts to leave the ground. Still used a jack stand for safety. Enjoy the New Ride and Control, I am. 5 Stars!

Decided to get these instead of an add-a-leaf system for my 2005 Chevy colorado Crew Cab. I was looking to stiffen the back of the truck without getting a bunch of lift. I cannot be more happy with the results. They installed in about an hour, and work great. I have them cranked about half way, and recently put 3 loads of well over 1000lbs in my truck.... it barely knew it was there. The handling has greatly improved, and the lean on corners I used to have has been greatly reduced. The only thing I did not like was the u bolts are not painted, and stand out like a sore thumb. I am planning on painting them. I also was pleased to get about 1/2" or so of lift. Just enough to make it look a little tougher without looking goofy. I almost could not believe the difference at first...really. As I said, these results are all with them set about half way cranked. I assume you could get more or less of these results by cranking more or releasing them a bit. Overall, great great purchase for my truck!P.S. I did find another way around the shock bolt issue. I installed the u-bolt, tightened it half way, and then was able to slide it up to the end of the spring. This pretty much was "going around" the shock bolt. Then I tightened it with an open ended wrench as opposed to a socket. I did not have to remove the shock bolt or do any cutting whatsoever. I do have the Z71 setup, so the previous review possibly did not.

Installed on these on my 2008 Colorado Crew Cab 4x4. These stiffened up the rear significantly and improved overall handling. They also raised the rear an inch or so. I adjusted the front torsion bars to level the truck which I think gives the truck an overall better look. There is a right and a wrong way to install these, so be sure to read what little instruction there is before you start. Some reviewers indicated some headaches, so my guess is there's variance between model years, etc... but, on my '08, these are not a difficult add-on for your average DIY.

I honestly can't say anything positive about these springs. I bought mine for use on a 2007 Isuzu i-290, which is made by GM and is the sister of the Chevy Colorado and the GMC Canyon. Due to various obstacles, the style designated for this application can't be mounted in a way that provides optimum performance from it's design. Take it from me, these are NOT "custom-fit". After installing these in the best conceivable location, they have delivered little in increased payload or ride-hieght. If you require either of these atttributes, I would suggest you purchase something different.

So, just wanted to add that these fit the Hummer H3. I have a 2010, but I'm sure it will fit all years. They do work well. No rear end sag and greatly reduce body roll.

Made a big difference on my truck. Will order again for my other one.

Really tightened up the rear end on my Colorado and only took about an hour to install.
