The 2011–2019 Chevy Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD 2WD/4WD can be equipped with this 3.5" System featuring Fabtech’s premium Uniball Upper Control Arms. These arms are built from .120" wall 4130 Chromoly tubing with a 1.50" OD and utilize 1" FK Stainless PTFE-lined Uniballs, providing up to 9" of front wheel travel and increased suspension strength.
The system also includes heavy-duty ductile iron steering knuckles and forged torsion bar adjusting keys designed to achieve proper lift height without inducing CV bind.
This setup levels the stance of the vehicle by eliminating the factory nose-down rake while retaining the stock rear suspension. For those who prefer the original nose-down appearance, optional 1" rear block kits are available (2500HD Part # FTS21110) or (3500HD Part # FTS21111).
