Needed addition stiffness in rear suspension when towing 30 ft. Travel trailer. Works beautifully!

my 2006 gmc sierra pick-up was sagging when loaded for work, if I took the trailer it would bottom out pulling into job sites. After installing a pair of Gabriel ultra on the front and Gabriel Hijackers on the rear of the truck I could easily adjust the ride about 70 for loads 60 for pleasure back to professional grade again.
