The Coachbuilder BulletProof 10"–12" Upgrade Kit is a complete supporting-hardware package for 2007–2021 Toyota Tundras already sitting on a BulletProof 10"–12" lift. Rather than chasing steering, ride height, and driveline fixes one part at a time, this bundle adds additional lift, strength, and travel in a single box: front coilover shims worth 1.00" of lift, a Coachbuilder steering kit, a rack and pinion polyurethane bushing kit, a driveline spacer, and +3" shackles that raise the rear about 2". Every component is made in the USA by Ekstrom Design and Fabrication Corporation.
Features
- Front coilover shim kit — provides 1.00" of additional front lift
- Coachbuilder steering kit with rebuildable chromoly joints, matched to the BulletProof application
- Rack and pinion polyurethane bushing kit
- Coachbuilder driveline spacer
- Coachbuilder +3" shackles — roughly 2.00" of rear lift
- All hardware included
- Made in the USA by Ekstrom Design and Fabrication Corporation
Only need one piece of the puzzle? The BulletProof 6"–8" & 10"–12" Steering Kit, +3" Shackle Kit, and Power Steering Rack Poly Bushing Kit are all available individually — or browse the full Coachbuilder lineup to build the package your truck actually needs.

Specifications
Coachbuilder BulletProof 10"–12" Upgrade Kit | Adds Lift, Steering & Driveline Upgrades | Fits Toyota Tundra 2007–2021 | Ekstrom Design FAQs
What exactly is included in this upgrade kit?
Six things: a Coachbuilder front coilover shim kit good for 1.00" of front lift, a Coachbuilder steering kit, a rack and pinion polyurethane bushing kit, a Coachbuilder driveline spacer, +3" shackles providing about 2.00" of rear lift, and the hardware to install it all. It is designed specifically for 2007–2021 Toyota Tundras already running the BulletProof 10"–12" lift kit.
How is this different from the BulletProof steering kit sold separately?
The standalone Coachbuilder BulletProof steering kit is steering only — billet arms and chromoly heims for the 6"–8" and 10"–12" lifts. This upgrade kit is the full supporting package for the 10"–12" application: it includes a steering kit plus front shims, rear shackles, poly rack bushings, and a driveline spacer, adding lift, strength, and travel in one order.
How much extra lift does it add?
The front coilover shim kit provides 1.00" of lift, and the +3" shackles provide roughly 2.00" of rear lift per the kit spec, on top of your existing BulletProof 10"–12" lift. Plan on an alignment after installing the front shims and steering kit, as with any change to ride height or tie rods on a 2007–2021 Tundra.
