1988-1998 GMC C1500 2WD 3"/5" Coil Lowering Kit + Shocks
Build a clean OBS stance with a complete Trekline package matched to the GMC C1500 chassis and the listed front/rear drop combination.
Cab / Rotor Fitment: This is a coil-spring-based lowering package and does not use front drop spindles. It fits 1988-1998 GMC C1500 2WD trucks with Standard or Extended Cab when the listed engine/suspension requirements are met. The 1.00-inch versus 1.25-inch front rotor distinction applies to spindle-based kits, not to this coil-only front lowering method.
Kit Contents:
- 3-inch front lowering coils (pair)
- 6-inch rear axle flip kit
- 1-inch rear lift shackles
- front drop shocks (pair)
- rear drop shocks (pair)
Vehicle Fitment:
- 1988-1998 GMC C1500 2WD
Important Fitment & Installation Notes:
- 454 SS: do not assume compatibility from rotor thickness alone. The 454 SS uses a different heavy-engine vehicle package; verify the exact front coil application before ordering.
- Cab fitment: fits Standard and Extended Cab 1988-1998 GMC C1500 2WD applications when the remaining kit-specific fitment requirements are met.
- Front and rear drop shocks are included so shock travel is matched more closely to the supplied lowering combination.
- 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.
