About Coachbuilder by Ekstrom Design

Ekstrom Design is a Salt Lake City company owned by David Ekstrom. It started out making lightweight suspension and interior parts for racing, then turned to off-road, and in 2009 launched Coachbuilder as a brand dedicated to Toyota trucks.

Coachbuilder parts are CNC machined from 6061-T6 billet aluminum, and the company is a SEMA member. It's best known for Tundra lift shackles, strut shims, steering upgrades for lifted Tundras, and carrier bearing and differential drop kits.

What we carry from Coachbuilder

We stock Coachbuilder rear lift shackle kits and rebuild kits, strut and coilover shims and bolt kits (find them under coil spacers), and bump stops, bushings and sway bar end links.

For bigger lifts there are steering and long-travel steering kits in tie rods, carrier bearing drops and driveline spacers in driveline components, front differential drop kits, and brake/ABS relocation and airbag spacer kits. Fitment covers the Toyota Tundra (1999–2006, 2007–2021, 2022+), Toyota Tacoma, 4Runner, FJ Cruiser, Sequoia, Lexus GX 470 and 2024+ Land Cruiser.

How to choose

Small parts, precise numbers. Most Coachbuilder fitment questions come down to reading the spec, not the headline.

• Shackle size isn't lift height. On a 2007–2021 Tundra, the +1" shackle adds about 0.625" of rear lift, +2" about 1.25" and +3" about 1.75".
• Coilover bolt kits come in metric M10x1.50 (Eibach, OME BP-51) or SAE 3/8" (ADS, Fox 2.5, Icon 2.5, King). Match your coilover's thread.
• Bigger lifts usually need support parts. Coachbuilder sells steering, carrier bearing and brake line kits matched to specific lift heights.
