Billet Spanner Wrench Kit Icon Vehicle Dynamics

The ICON Vehicle Dynamics Billet Spanner Wrench Kit is a purpose-built aluminum tool designed for coilover preload adjustment — and it's more thought-out than anything else in this category. We like this kit because ICON addressed every friction point in the adjustment process and packed the solutions into one billet piece.

Two 3/8-inch dowels cover your access scenarios: the hooked dowel gives you leverage against the adjuster nut in open applications, while the straight dowel handles tight clearance situations without forcing awkward angles. A 5/32-inch allen wrench rides magnetically on the back of the handle — ready when you need to hit the collar set screw, gone when you don't. No more walking back to the toolbox mid-adjustment.

The laser-marked measurement guides are the spec we keep coming back to. On-the-spot preload measurement without a separate device cuts real time out of the process. When you're done, the magnetic back sticks to any ferrous surface for clean storage in the garage or the truck bed.

ICON also machined in a bottle opener — which sounds like a gimmick until you've finished a suspension setup in a parking lot. It's not a gimmick.

Black anodized aluminum handle. Non-adjustable, fixed 3/8-inch opening. Built for home garages, professional shops, and trail-side adjustments alike. If you're running ICON coilovers, this wrench belongs in your kit.
