    Product Description

    Description:

    This Trekline Motorsports 4"/6" drop kit lowers a 1999-2006 Chevy Silverado 1500 or GMC Sierra 1500 4WD pickup. Up front, 2" drop spindles and adjustable lowering torsion keys combine for the 4" front drop. Out back, a 6" flip kit relocates the rear axle above the leaf springs for the 6" rear drop. Drop-specific front and rear shocks are included.

    4WD (4x4) models only. Requires torsion bar front suspension. 17"+ rims required — 17"/18" rims must run our lower ball joint hardware kit (see related items). C-Notch is REQUIRED for this drop and is NOT included — see our other listings.

  • 2" Drop Spindles (pair)
  • 2"-3" Adjustable Lowering Torsion Keys (pair)
  • 6" Rear Flip Kit
