Fabtech Suspension Lift Kit Component Box
4? Budget Uca System W/ Performance Shocks
Our 4" Ultimate System provides less lift than our 6" RTST system but still allows use of 33" or 35" tall tires with cutting for street and offroad use. We have developed this system utilizing replacement upper control arms constructed of 1.50" OD .120" thick wall DOM tubing that attaches to heavy duty Fabtech ductile iron steering knuckles. The factory torsion bars remain in the stock position and use new forged adjusting keys to provide the proper amount of lift.
- Upper Control Arms Built With Same Materials Found On Trophy Trucks
- .120" Wall 4130 Chromoly Tubing. 1.50" OD
- .250" wall DOM Bushing Barrels
- Extended Range Ball Joints
- Ductile Iron Steering Knuckles
- Forged Torsion Bar Keys
