- 33" x 12.5" tire compatibility: roomier tires for off-road traction without compromising handling.

- Warranty: limited lifetime warranty on leaf springs; all lift kits backed by a limited lifetime warranty for long-term peace of mind.
- Installation notes: average installation time is 4–6 hours with standard tools, making it a practical upgrade for weekend projects.
- Fitment: designed for 1/2-ton GM models and specific 1988–1991 4WD configurations; not compatible with diesel engines.

The combination of heavy front springs, rear blocks, and SX8000 shocks delivers a composed ride, better load handling, and improved tire clearance, helping you tackle trails, snow-covered roads, and everyday driving with added confidence.
