The 2011–2019 Chevy Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD 2WD/4WD can utilize this 3.5" System featuring Fabtech’s premium Uniball Upper Control Arms. These arms are constructed from .120" wall 4130 Chromoly tubing with a 1.50" OD and equipped with 1" FK Stainless PTFE-lined Uniballs, providing up to 9" of front wheel travel and increased suspension strength.
The system includes heavy-duty ductile iron steering knuckles and forged torsion bar adjusting keys designed to achieve the proper amount of lift while preventing CV bind.
This system levels the vehicle’s stance by eliminating the factory nose-down rake while retaining the stock rear suspension. For customers who prefer the original nose-down look, optional 1" rear block kits are available (2500HD Part # FTS21110) or (3500HD Part # FTS21111).
