Zone Offroad 3" Adventure Series (UCA) Lift System 01-10 GM 2500HD / 3500 2001-2010 GM 2500HD / 3500 4x4

Take your GM to new heights with this complete suspension system from Zone!

This Adventure Series lift systems is built around the Zone Offroad heavy-duty replacement upper control arms 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 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, two 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.
