1988-1991 Chevrolet/GMC C1500 Standard Cab 2WD 6" Lift Kit with 2" Rear Leveling Block - 1" Rotors + Front & Rear Shocks | Trekline 1350LFT110020
If your 1988-1991 OBS C1500 is a standard cab, 2WD, and actually measures approximately 1 inch across the front rotor, this 6-inch front lift is the correct light-duty-brake Trekline family. SKC names the package by its 6-inch front lift height; the 2-inch rear block is listed separately because it is the rear stance/leveling component, not a second advertised lift-kit height.
Why This 6" Setup Is Different
The 6-inch front setup pairs lift spindles with 2-inch coil spacers for a noticeably taller GMT400 stance. It is a common height range for owners building an OBS C1500 around larger wheels and tires while retaining the factory coil-spring front layout. The 2-inch rear block adds useful rear clearance while still allowing the front lift to visually lead the stance. Final ride height and rake can vary with spring age, accessories, bed load and vehicle condition.
This version includes matched front and rear lift shocks plus the required shock mounting hardware, so the suspension package is more complete out of the box.

Exact Vehicle Fitment

Measure the Front Rotor Before Ordering
Standard cab does not automatically mean 1-inch brakes. Measure the front rotor thickness before ordering. These lift spindles do not fit the approximately 1.25-inch heavy-duty brake package and do not fit factory 454 SS models. SKC also carries the separate Trekline 1.25-inch-rotor C1500 lift-kit family for those trucks.
Installation & Wheel Notes
- 2WD C1500 coil-spring front suspension only; not for K1500/4WD or C2500.
- Requires 15-inch or larger wheels with a maximum 4.5-inch backspacing.
- Some 15-inch wheels may require minor spindle grinding or a wheel spacer for clearance.
- Lift spindles increase front track width approximately 1 inch per side.
- Factory alignment knockouts must be removed for fine alignment adjustment.
- Aftermarket upper control arms are recommended with this front coil-spacer height.
- Professional installation and a complete wheel alignment are recommended.
- Check brake hoses, ABS wiring, steering, suspension, tire and wheel clearance through full travel.
- Check rear shock travel, brake-hose clearance and driveline angles after lifting.
- U-bolts may need to be shortened after final torque; verify thread engagement and clearance before trimming.
