Chevrolet/GMC 2500/3500 HD 4WD 3" Adventure Series UCA Lift System 01-10

Zone Offroad Chevy/GMC 2500/3500 HD 4WD 3" Adventure System 2001-2010

This new addition to the Adventure Series lineup of lift systems is built around the Zone Offroad heavy-duty replacement upper control arms already available for the 01-10 HD trucks. The arms are made from 3/16" steel that is precision laser cut, formed and fully welded. Preinstalled Raybestos brand ball joints and rubber bushings provide an easy installation and long service life. The ball joint is repositioned to compensate for the added lift and maintain a neutral position at ride height. To complement the improved upper ball joint angles, the kit address the other area often ignored at this lift height - the CV shafts. 

The new Adventure Series kit for the 01-10 HDs includes a full differential drop system that relocates the differential down 2" for near stock angles at the 3" lift height. This is accomplished with a drop spacer on the passenger's side, (2) drop brackets for the front driver's mount and a integrated "half crossmember" for the driver's rear mount. A new different skid plate is included to protect the differential in its new position. The rear is lifted via a 2" block and u-bolts. 

Front and rear Nitro shocks are included.
