1988-1991 GMC C1500 2WD Standard Cab 2" Front / 1-2" Rear Drop Spindle Kit
Build a clean OBS stance with a complete Trekline package matched to the GMC C1500 chassis and the listed front/rear drop combination.
This is the dedicated 1988-1991 Standard Cab version. Trekline separates these trucks from its broader 1988-1998 C1500 kits, so this SKU should not be substituted with a 1300-series kit.
Kit Contents:
- 2-inch front drop spindles (pair)
- 1-2 inch adjustable rear drop shackles
Vehicle Fitment:
- 1988-1991 GMC C1500 2WD Standard Cab only
Important Fitment & Installation Notes:
- Cab fitment: 1988-1991 GMC C1500 2WD Standard Cab only. Do not use on Extended Cab trucks or 1992+ models.
- Brake rotor check: the Standard Cab spindle application is associated with the 1.00-inch front rotor setup. Measure rotor thickness and verify the complete brake/spindle configuration before ordering.
- Drop shocks are not included. Select shocks with travel appropriate for the final lowered ride height; deeper rear drops generally require shorter shocks.
- Measure the truck before ordering. Lowering amounts are referenced from stock OEM ride height, so worn springs or previous suspension changes can affect the measured result.
- Perform a professional alignment after installation and verify wheel/tire clearance, brake-hose routing, bump-stop clearance, shock travel and fastener torque before regular road use.
Front Drop: 2 inches
