Review on Enhance Your Vehicle's Performance with AIR LIFT 81560 1000 Series Rear Air Spring Kit by Jason Wright

Update: Worked great while it lasted but after just a year the valve stem broke out of one of the pockets . Disappointing quality. I installed them on the front coil springs of a 1996 G30 van. Prior to installation, I only had 0.5 inches of front suspension travel before hitting the rubber bumpers and hitting the ground many times. Once installed and pumped up to 70psi I have just over two inches and the suspension is much stiffer. The car no longer reaches the ground. Installation took four hours, two hours indoors trying to fold the airbags to a diameter that would fit through the hole in the lower A-arm (it's just over a 1 1/2" ABS tube) .Remove the valve stem. By combining a hot water bath, brute force, and lots of 3/8" zippers, I achieved a triple fold that did the job. The zip ties provided are rubbish. Don't waste your time with it. Pay special attention to the valve so that it rotates around it tight enough. Use the ABS tube as a guide. Lift the front off the ground from the outside to stretch the springs as much as possible. Guide fully inflate the airbag and then cut the top zippers and partially inflate the bag.Insert the top washer, centering it on the bag and pushing the bag all the way into the spring, cut and remove the remaining zipper, inflate the bag until round, and deflate the bag again. bag and place the bottom washer in the spring, centered around the valve. Attach air lines. I pointed mine at the battery compartment and used the zip ties to secure it to the existing hardware. Insert valve stem and inflate to desired pressure. It's been two months and the system is working great.
