They were a bear to install on my 2005 GMC crew cab but am totally satisfied with the end results. Wanted to remove the 4" lift block to eliminate the spring wind up. The spring actually gained about a 1/2" in height and got rid of the spring wind up problem

I own a GMC Sierra 1500 and tow a 7'x12' 7000# gvw enclosed trailer full of shelves and carpentry tools. It is quite heavy. Before I installed the suppersprings the rear of my truck would settle down 2" when I coupled up the trailer. It took me about a 1hr to install in my driveway. I put the rollers on the hole closer to the spring. Now the rear of my tuck only settles about 5/8" to 3/4". Preloading the spring brought up the rear about 2" from stock, which I was looking for also.
