Rancho 19-22 Chevrolet Silverado 1500 Suspension System Component - Box One

The upper control arms in this Rancho suspension system component are fabricated from high-strength, low-alloy steel, offering a solid foundation for your truck's lift. This specific box, RS66311R9-1, is the first of three required for the complete Rancho 3-inch suspension system designed for your 2019-2025 Chevrolet Silverado 1500 or GMC Sierra 1500 (excluding Trail Boss and AT4 models). It includes upper control arms with pre-installed, OE-style ball joints and durable rubber bushings, which are designed for easy maintenance and quiet operation. These control arms also provide additional caster to help with alignment and keep the ball joints within their normal operating range.

When paired with the other components of the master kit, this system lifts the front of your truck by 3 inches and includes rear blocks to raise the back by 1.5 inches, leveling the stance. It's engineered to maintain OE alignment specifications and won't interfere with the electronic stability system, allowing the use of your factory wheels and tires. This box also contains the Rancho RS9000XL front struts and rear shocks, which feature a nine-position knob for customized damping control, giving you flexibility for both on-road and off-road driving.

This is a bolt-on installation, making it a straightforward upgrade. Remember, this is only Box 1 of 3 for the complete RS66311R9 kit; you'll need to order RS66311R9-2 and RS66311R9-3 to complete the installation.
