About this kit
Vertex 2.5 Adjustable Front Coilovers, fitment-checked
Rough Country 689034 is a matched pair of Vertex 2.5 adjustable front coilovers for 2007-2021 Toyota Tundra 4WD models, supplied as a left and right 3.5 in unit. They are intended for trucks already running a 3.5 in lift and cannot be installed alongside a strut spacer. The adjustment wrench, SKU 10403, is a separate purchase. Carries a 3 Year Limited Warranty.
This Vertex 2.5 adjustable front coilover set covers 2007-2021 Toyota Tundra 4WD applications from SR and SR5 through Limited, Platinum, 1794 Edition, Nightshade, Trail, and TRD Pro. Each side uses a monotube, nitrogen-charged body with a 2.5 in piston, an 18mm chrome-hardened rod, and a remote reservoir on a steel-braided line to move heat away from the damper. Zinc plating with a double clear coat handles corrosion. Confirm your truck already has a 3.5 in lift and no strut spacer, then plan on roughly 2-3 hours with the downloadable installation guide.
