3.5 Inch Lift Kit | Mono Leaf Rear | N3 Struts | GMC Sierra 1500 (25-26)

Elevate your GMC Sierra 1500 (model years 2025–2026) with Rough Country's 3.5-Inch Suspension Lift Kit. This upgrade adds height and presence while preserving ride quality, ideal for drivers who want more than a level—without jumping to a full 6-inch lift.

• Upper Control Arms: Forged aluminum upper control arms maintain factory-like suspension geometry for predictable handling and reduced tire wear.
• Shock Configuration: Configurable to pair with Rough Country N3 nitrogen-charged shocks or Vertex reservoir shocks, so you can choose dampers that suit your driving style.
• Tire Clearance: Supports up to 295/55R20 tires for a more aggressive look and improved off-road capability.
• Compatibility: Specifically designed for GMC Sierra 1500 (25–26 model years).
• Installation: Strut compressor required; estimated 5–6 hours; feasible for a capable DIY install.
• Warranty: Limited Lifetime Replacement Warranty against manufacturing defects.

This lift preserves essential suspension geometry to deliver a smooth, controlled ride with larger tires and a more capable stance. By keeping angles close to stock, it helps maintain steering response, steering wheel feel, and tire wear characteristics, while the enhanced ground clearance enables confident off-road excursions and improved approach/departure angles. The ability to choose between N3 or Vertex shocks lets you tailor damping for comfort on daily commutes or refined performance on rough trails. Best suited for Sierra 1500 owners seeking a balanced upgrade for daily driving, weekend adventures, and light-to-moderate off-roading, all with a factory-backed, peace-of-mind warranty.
