Overview
The Rancho RS999949 is a loaded front strut assembly that lifts the front 2 inches on 2014 through 2019 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks.
The quickLIFT Loaded assembly levels and lifts the truck, and it allows larger wheel and tire packages without the cost of a complete suspension system or the long installation time that comes with one. Each unit is a gas charged modular assembly with an application-specific coil spring and an upper mounting plate already installed.
The assembly uses RS9000XL nine-position adjustability, which lets owners tune the ride to the terrain and their preference. The units carry a limited lifetime warranty.
Key features
- Gas charged complete modular strut assembly
- Application-specific coil spring installed
- Upper mounting plate included
- RS9000XL nine-position adjustability
- 2-inch front lift
Before and after a strut swap
A loaded strut replaces the complete strut assembly, so the work is more involved than swapping a coil spring. Before the old unit comes off, support the truck safely and note the position of any brake lines and wiring. Plan on a wheel alignment once the new assembly is in, since a lift changes camber and caster settings and the steering can pull if the truck is left unaligned.
Most owners replace the whole unit when wear appears rather than rebuilding the strut. Signs of a worn strut include fluid on the body, a bouncy ride after bumps, and uneven tire wear. Check the upper mounts and bump stops while the front end is apart, since they often wear alongside the strut. Keeping tires at the correct pressure reduces extra load on the new assembly.
- Confirm alignment after installation
- Check upper mounts and bump stops
- Look for fluid on the body

Vehicle fitment
It fits the 2014–2018 Chevrolet Silverado 1500 and the 2014–2018 GMC Sierra 1500, plus the 2019 Silverado 1500 LD and the 2019 GMC Sierra 1500 Limited.
The list does not include HD trucks or any model years after 2019. Confirm your vehicle’s year, model and trim before ordering.
Installation notes
A 2-inch front lift changes the front geometry, so have the alignment checked after installation. Because the unit arrives with its coil spring and upper mounting plate, the job is a complete strut swap rather than a spring-only change.
