About this kit
Vertex 2.5 Adjustable Front Coilovers, fitment-checked
Rough Country 689031 is a pair of Vertex 2.5 adjustable front coilovers for 2007-2018 Chevrolet Silverado 1500 and GMC Sierra 1500 trucks, plus the 2019 Silverado 1500 LD. The set is intended for trucks already set up with 3.5 in of lift and cannot be run alongside a strut spacer. Driver and passenger units are both in the box; the adjustment wrench, SKU 10402, is a separate purchase.
These Vertex 2.5 adjustable front coilovers cover 2007-2018 Silverado 1500 and Sierra 1500 applications in 4WD, RWD and AWD, the 2019 Silverado 1500 LD, and 2010-2018 Sierra SLE and SLT trims listed in the fitment section. Each unit uses a monotube, nitrogen-charged body with a 2.5-inch piston, an 18mm chrome-hardened rod, and a remote reservoir on a steel-braided line. Ride height must already sit at 3.5 in of lift, and strut spacers must come out first. Rough Country lists install time at 2-3 hours, and a downloadable installation and adjustment guide is available.
