1988-1991 Chevrolet C1500 2WD Standard Cab 4"/6" Spindle + Coil Lowering Kit + Shocks
Build a clean OBS stance with a complete Trekline package matched to the Chevrolet 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)
- 2-inch front lowering coils (pair)
- 6-inch rear axle flip kit
- front drop shocks (pair)
- rear drop shocks (pair)
Vehicle Fitment:
- 1988-1991 Chevrolet C1500 2WD Standard Cab only
Important Fitment & Installation Notes:
- Cab fitment: 1988-1991 Chevrolet 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.
- Front and rear drop shocks are included so shock travel is matched more closely to the supplied lowering combination.
- A C-notch is not included with this SKU. Verify axle-to-frame clearance at full compression; a notch may be required or strongly recommended depending on final ride height and use.
- Inspect driveshaft operating angle after lowering. Trucks with a 2-piece driveshaft may need carrier-bearing geometry correction depending on the final setup.
- 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.
