2014 Sierra SLE Z71 with a 2/4 (which actually measures 1.75" lower in the front, and 3.25" lower in the rear)
Components:
Helwig Sway Bar
Belltech front adjustable struts
Belltech rear shocks
Belltech rear lowering kit (shackles, U-bolts, plates etc)
Consistent with many other owner's feedback, the Belltech's are a huge improvement in ride quality over the very harsh Ranchos that come on a Z71. As for the Hellwig sway bar, and I gotta tell ya.............it transforms the truck. Sure, it sits flat railing around a cloverleaf on the freeway, but you can really feel the difference ALLthe time, even just pulling away from a light and turning left or right, it feels way tighter/flatter. There are three stiffness settings for the sway bar, and they set me up at the least stiffest of the three to start. I'll have them adjust it to the stiffest and let you folks know how it feels.
