Eibach and Old Man Emu BP51 coilovers take metric hardware, so Coachbuilder builds this dedicated M10 bolt kit for 2007–2021 Toyota Tundra owners installing strut shims on those coilovers. You get eight M10x1.50x40mm bolts plus eight flat washers and eight lock washers — full coverage for both sides of the truck in a single kit. If the coilovers under your Tundra say Eibach or BP51, this is the hardware to put in the cart next to your shims; the SAE 3/8" kit that fits ADS, Fox, Icon, and King setups won't do the job here.
Features
- Eight M10x1.50x40mm bolts — the metric thread Eibach and Old Man Emu BP51 coilovers require
- Eight flat washers and eight lock washers complete the kit
- Covers both sides of the truck — four bolts per corner
- Required when installing Coachbuilder strut shims with Eibach or OME BP51 coilovers
- Sized for the 2007–2021 Toyota Tundra
- Metric counterpart to the SAE 3/8" kit used with ADS, Fox 2.5, Icon 2.5, and King coilovers
Pair it with the shim that sets your ride height — from the .25" Tundra shim up to the 1.00" Tundra shims. If your truck runs ADS, Fox 2.5 Series, Icon 2.5 Series, or King coilovers, order the SAE 3/8" Shim Bolt Kit instead. Browse the full Coachbuilder lineup for the rest of the build.

Specifications
Coachbuilder Strut / Coilover Shim Bolt Kit | Metric M10x1.50 for Eibach & Old Man Emu BP51 Coilovers | Fits Toyota Tundra 2007–2021 | Ekstrom Design FAQs
Will this kit work with my Fox, Icon, or King coilovers?
No — this is the metric kit, built for Eibach and Old Man Emu BP51 coilovers on the 2007-2021 Toyota Tundra. ADS, Fox 2.5 Series, Icon 2.5 Series, and King coilovers use SAE hardware and take the separate 3/8" Grade 8 Shim Bolt Kit. Match the bolt kit to the coilover brand before ordering.
What exactly is included in the kit?
Eight M10x1.50x40mm bolts, eight flat washers, and eight lock washers — four of each per side, covering both sides of the truck. That's the full hardware set Coachbuilder specifies for installing its strut shims on Eibach or Old Man Emu BP51 coilovers on a 2007-2021 Tundra.
Do I need this kit to install shims on my BP51 coilovers?
Yes. Coachbuilder lists this metric bolt kit as required when using its strut shims with Eibach or Old Man Emu BP51 coilovers. The M10x1.50 thread and 40mm length are matched to that combination on the 2007-2021 Tundra, so skip the hardware-store guesswork and order it with your shims.
