1988-1991 Chevrolet/GMC C1500 Standard Cab 2WD 7" Lift Kit with 5" Rear Leveling Block - 1" Rotors | Trekline 1350LFT110033
Built specifically for light-duty-brake GMT400 standard cabs, this Trekline package gives a 1988-1991 Chevy or GMC C1500 approximately 7 inches of front lift without using the heavy-duty 1.25-inch-rotor spindle. SKC names the package by its 7-inch front lift height; the 5-inch rear block is listed separately because it is the rear stance/leveling component, not a second advertised lift-kit height.
Why This 7" Setup Is Different
This is the tallest front-lift combination in this Trekline 1-inch-rotor standard-cab family. The 4-inch spindles and 3-inch front spacers create the full 7-inch front rise, so upper-control-arm geometry, alignment range and wheel clearance deserve extra attention. The 5-inch rear block provides the most rear lift in this family, favoring rear clearance and a more pronounced rake compared with the lower block choices. Final ride height and rake can vary with spring age, accessories, bed load and vehicle condition.
This base version does not include shocks, which is useful when the truck already has compatible extended-length shocks or the builder wants to choose a specific shock separately.

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.
