Coachbuilder Coilover Bolt Kit | Metric M10x1.50 for Eibach & Old Man Emu BP51 Coilovers | Fits Toyota Tacoma, 4Runner, FJ Cruiser 2005+ & Tundra 1999–2006 | Ekstrom Design
Coachbuilder shims go onto Eibach and Old Man Emu BP51 coilovers with metric hardware, and this kit supplies exactly that: six M10x1.50x40mm bolts with six flat washers and six lock washers, covering both sides of a 2005+ Tacoma, 4Runner, or FJ Cruiser — or a 1999–2006 Tundra. It does the same job the SAE kit does for ADS, Fox, Icon, and King setups, just in the thread BP51 and Eibach coilovers actually take. Match the kit to the coilover brand, not the truck, and the shim install goes through without a second parts run.
Features
- Six M10x1.50x40mm bolts — metric thread for Eibach and Old Man Emu BP51 coilovers
- Six flat washers and six lock washers round out the kit
- Covers both sides of the truck — three bolts per corner
- Required when installing Coachbuilder shims on Eibach or OME BP51 coilovers
- Fits 2005+ Tacoma, 4Runner, and FJ Cruiser plus 1999–2006 Tundra
- Not for ADS, Fox 2.5, Icon 2.5, or King coilovers — those take the SAE 3/8" kit
Order it with the .50" shim or 1.00" shims for these trucks — first-gen Tundra owners can pair it with the .50" shim for the 1999–2006 Tundra. Running ADS, Fox 2.5 Series, Icon 2.5 Series, or King coilovers instead of BP51s? That calls for the SAE 3/8" Coilover Bolt Kit.

How is this different from the SAE coilover bolt kit?
Thread standard. This kit's six M10x1.50x40mm bolts are metric, matched to Eibach and Old Man Emu BP51 coilovers, while the SAE kit's 3/8"-16 Grade 8 bolts fit ADS, Fox 2.5 Series, Icon 2.5 Series, and King coilovers. Both cover the same trucks — 2005+ Tacoma, 4Runner, and FJ Cruiser plus the 1999-2006 Tundra — so pick by coilover brand.
What's included, and does it cover both sides?
Six M10x1.50x40mm bolts, six flat washers, and six lock washers — three of each per side, so one kit covers both front coilovers. That's the hardware Coachbuilder specifies for installing its shims on Eibach or Old Man Emu BP51 coilovers on these trucks.
Will this fit my 2018 4Runner with BP51 coilovers?
Yes. The kit covers 2005+ Tacoma and 4Runner along with the FJ Cruiser and 1999-2006 Tundra, and Old Man Emu BP51 is exactly what it's built for — Coachbuilder lists this metric kit as required when running its shims on BP51 or Eibach coilovers.
