Our 4” Ultimate System provides less lift than our 6” RTS™ 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

DIRT LOGIC 2.25 SHOCK

Dirt Logic 2.25’s are designed to replace factory shocks with a larger, more robust configuration. The 2.25 size is what separates it from other replacement take apart shocks for a superior ride, both on and off road. Shocks are pretuned for each Fabtech suspension, accounting for larger tires, providing the finest all around damping.

• 2.25″ OD Stainless Steel Body
• 2.0″ OD Billet Aluminum Piston
• 7/8″ NitroSteel® Black Piston Rod
