Upgrade Your Stance Without Sacrificing Ride Quality

If you're ready to give your 2025 Sierra or Silverado 1500 a real presence on and off the pavement, the Fabtech K1213M 3" Uniball UCA System delivers everything you’re after. This lift kit isn’t just about adding height, it’s about unlocking a more capable and aggressive truck without turning it into a stiff, rattling mess. With 3 inches of added clearance, you’ll have the space to throw on larger wheels and tires, opening the door to serious trail potential and a much tougher street look. The ride stays smooth thanks to quality components like Fabtech’s Stealth monotube shocks and precision-built upper control arms. Installation is straightforward and doesn’t require cutting or welding, which means you’ll spend more time driving and less time wrenching. Everything you need is in the box, including hardware, rear lift blocks, and U-bolts. It’s a complete system that upgrades your stance, improves wheel travel, and keeps your truck daily-driver friendly. Plus, it’s backed by a solid 5-year, 60,000-mile powertrain warranty, giving you confidence long after the install is done.

Built With Strength Precision And Daily Comfort In Mind

This Fabtech 3" Uniball UCA System is engineered specifically for the 2025 GM Sierra and Silverado 1500, both 2WD and 4WD, and is designed to directly replace the factory suspension with high-strength components built for long-term performance. The system features heavy-duty upper control arms equipped with 1-inch FK uniball joints, offering superior articulation and durability over stock ball joints, especially under off-road conditions. Front strut spacers are included to lift the front end without affecting factory alignment specs, while the rear is leveled with lift blocks and heavy-duty U-bolts to maintain proper geometry and load support. This kit also includes Fabtech Stealth monotube shocks, which are nitrogen-charged and built for consistent damping in both on-road and off-road conditions. With its bolt-on design, no cutting or major modifications are required, allowing for a clean installation that retains the truck’s factory ride comfort. The complete kit also includes all necessary hardware, ensuring a smooth install process from start to finish. OEM wheels and tires cannot be reused with this kit, so aftermarket wheel fitment will be required to fully take advantage of the added clearance.
