This six-bolt SAE kit is the required hardware for installing Coachbuilder shims with ADS, Fox 2.5 Series, Icon 2.5 Series, or King coilovers on a 2005+ Tacoma, 4Runner, or FJ Cruiser — and it covers the 1999–2006 Tundra too. Inside are six Grade 8 bolts in 3/8"-16 x 1.50" with six Grade 8 flat washers and six lock washers: three of each per side, both sides of the truck in one kit. These platforms take three fasteners per corner, which is why this kit runs six bolts where the 2007+ Tundra version runs eight.
Features
- Six Grade 8 bolts, 3/8"-16 x 1.50" — SAE thread for ADS, Fox 2.5, Icon 2.5, and King coilovers
- Six Grade 8 flat washers and six Grade 8 lock washers included
- Covers both sides — three bolts per corner on these platforms
- Required when installing Coachbuilder shims with the listed coilover brands
- Fits 2005+ Tacoma, 4Runner, and FJ Cruiser plus 1999–2006 Tundra
- Made in the USA
Add it to the order with your shims — the .250" shim and .50" shim for these trucks both install with this hardware. Running Eibach or Old Man Emu BP51 coilovers? You need the Metric M10 Coilover Bolt Kit instead. Sticking with TRD Pro coilovers or OE-style studs? The Coachbuilder Hardware Kit swaps the collar nuts so two shims fit.

Specifications
Coachbuilder Coilover Bolt Kit | SAE 3/8" Grade 8 for ADS, Fox 2.5, Icon 2.5 & King Coilovers | Fits Toyota Tacoma, 4Runner, FJ Cruiser 2005+ & Tundra 1999–2006 | Ekstrom Design FAQs
Which bolt kit fits my coilovers, SAE or Metric?
This SAE kit — six Grade 8 bolts in 3/8"-16 x 1.50" — is required when installing Coachbuilder shims with ADS, Fox 2.5 Series, Icon 2.5 Series, or King coilovers. If your truck runs Eibach or Old Man Emu BP51 coilovers, you need the Metric M10 Coilover Bolt Kit instead. The two use different threads and are not interchangeable.
Why does this kit have six bolts when the Tundra kit has eight?
Because they cover different trucks. This kit fits the 2005+ Tacoma, 4Runner, and FJ Cruiser plus the 1999-2006 Tundra, where six bolts — three per side — cover both coilovers. The 2007-2025 Tundra uses the separate eight-bolt Shim Bolt Kit. Order the kit that matches both your truck and your coilover brand.
Will this fit my 2015 Tacoma with Fox 2.5 coilovers?
Yes — the kit covers 2005+ Tacoma, 4Runner, and FJ Cruiser along with the 1999-2006 Tundra, and Fox 2.5 Series is one of the coilover brands it's specified for, alongside ADS, Icon 2.5 Series, and King. You get six Grade 8 bolts with flat and lock washers, made in the USA, covering both sides of the truck.
