Fitment Table
| Year | Drive | Make | Model |

| 2007–2018 | 4WD | GMC | Sierra 1500 |
Key Performance Features
Unlike other “stacked” systems that use extended spacers on 6-inch kits, this Superlift kit was purpose-built for a true 8-inch lift from day one. All components are matched for long-term performance and structural accuracy.
Highlighted Features
- True 8-Inch Lift System with geometry-correct steering knuckles and differential drops
- Engineered using OE CAD files for factory-level fitment and compatibility
- Maintains ride quality and integrates with GM Stabilitrac® system
- Brake lines and sway bar brackets relocated to eliminate suspension binding
- Diff skid plate adds rigidity and protects critical components
- Rear lift achieved using fabricated blocks with full upper/lower plate lock-in
- Captive U-bolts reduce axle wrap and secure the leaf pack
Why It’s a TRUE 8-Inch System
Unlike kits that cut corners by stacking spacers onto 6" designs, Superlift’s knuckles, crossmembers, and diff drops are engineered specifically for a full 8" of lift. This ensures all drivetrain, brake, and steering components operate within correct tolerances, preserving long-term performance and safety.
Rear Block Innovation
The included rear fabricated lift blocks are among the strongest in the industry. Their upper and lower plate design locks U-bolts in place and integrates seamlessly with the leaf spring pack, reducing the risk of axle wrap or misalignment under heavy torque.
