07-20 GM LOWER STRUT SPA CRS

The 07-20 GM Lower Strut Spacer Crossmember by Skyjacker is an essential suspension component designed for vehicles experiencing suspension geometry changes from lift kit installation. This spacer addresses a critical clearance issue that occurs when lifting your truck or SUV—the lower strut mounting point moves relative to the frame, potentially compromising suspension travel and component alignment. Anyone planning a serious lift installation on 2007–2020 General Motors platforms needs to understand that proper suspension geometry maintenance directly impacts ride quality, tire wear, and handling dynamics.

This lower strut spacer functions by repositioning the lower control arm attachment point relative to the strut assembly, maintaining correct suspension angles as your vehicle sits higher. Skyjacker's engineering ensures the spacer maintains OEM-equivalent load paths while accommodating increased ride height, preventing binding and excessive angle changes that would accelerate ball joint and bushing wear. The compact 6.4 x 4.3 x 7.2 inch design fits seamlessly into tight suspension packaging, and at 4.75 lbs it adds minimal unsprung weight—critical for preserving ride quality and shock response. Precision machining and proper material composition allow this component to withstand the dynamic stresses of off-road use and aggressive driving without flexing or degrading over time.

Mechanics and lift enthusiasts who run 4-inch or larger suspension packages on Silverado 1500, Sierra 1500, or other applicable GM platforms will find this spacer mandatory for maintaining suspension geometry integrity. Installation pairs perfectly with full lift kits, extended control arms, and adjustable track bars, ensuring all components work in harmony rather than fighting against misaligned geometry. Proper installation—which requires removing the lower strut mount and installing the spacer before reassembly—takes roughly 30–45 minutes per side once the vehicle is properly supported. This is not a bolt-on cosmetic upgrade; it's engineering-focused suspension maintenance that protects your investment in both the lift kit itself and your vehicle's long-term suspension health.
