Learn how to install a 2.5-inch strut spacer on your 2007-2021 Toyota Tundra. Step-by-step instructions, common mistakes, and product tips included.

Quick Answer

Installing a 2.5-inch strut spacer on your 2007-2021 Toyota Tundra is a straightforward bolt-on job that levels the front end without replacing the entire suspension. The Body Armor 4x4 2.5" Strut Spacer is a popular choice for this upgrade.

Why a Strut Spacer Instead of a Full Lift Kit?

A strut spacer lift is one of the most cost-effective ways to level your Tundra. It raises the front by adding a spacer between the strut and the frame, keeping your factory struts and springs. This means you maintain stock ride quality and can return to stock height easily if needed.

The trade-off is that you don't get increased wheel travel or heavier spring rates. If you regularly carry heavy loads or go rock crawling, a full coilover or suspension lift might be a better fit. For daily driving, light off-roading, or fitting larger tires, a strut spacer works well.

Tools and Preparation

Before starting, gather basic hand tools: a floor jack, jack stands, socket set (metric and standard), torque wrench, and a spring compressor (if you plan to disassemble the strut assembly). Some installations can be done without a spring compressor by using the bolt-on spacer method.

Park on level ground, chock the rear wheels, and disconnect the battery negative terminal. Allow the vehicle to cool if it has been driven. Have the Body Armor 4x4 2.5" Strut Spacer kit ready, including the spacer plates, bolts, and instructions.

Step-by-Step Installation

1. Lift and Secure the Front End: Jack up the front of the Tundra and place jack stands under the frame rails. Remove the front wheels. Make sure the vehicle is stable before proceeding. Common mistake: not using jack stands. Never work under a vehicle supported only by a jack.
2. Remove the Strut Assembly: Remove the brake line bracket and ABS sensor wire from the strut. Unbolt the lower strut bolts and the upper strut mount nuts (usually three). Carefully lower the strut assembly out of the vehicle. Checkpoint: mark the orientation of the upper mount before removal to avoid reinstallation errors.
3. Install the Spacer: Place the Body Armor 4x4 strut spacer on top of the strut assembly, aligning the bolt holes. Use the provided hardware to secure the spacer between the strut and the upper mount. Torque to manufacturer specifications (typically around 80-100 ft-lbs). Common mistake: over-tightening can strip threads or damage the spacer. Use a torque wrench.
4. Reinstall the Strut Assembly: Lift the strut assembly back into place. Start the upper mount nuts by hand to avoid cross-threading, then tighten them. Reinstall the lower strut bolts and torque them. Reattach the brake line bracket and ABS sensor wire. Checkpoint: ensure the brake line and ABS wire are not pinched or stretched when the suspension is at full droop.
5. Reinstall Wheels and Lower the Vehicle: Put the wheels back on, hand-tighten the lug nuts, and lower the Tundra to the ground. Torque the lug nuts in a star pattern to the vehicle's recommended spec (usually 80-100 ft-lbs). Common mistake: skipping the final torque check. Loose lug nuts can cause wheel separation.
6. Check Alignment and Test Drive: After installation, the front end will be 2.5 inches higher. This changes the steering geometry, so a front-end alignment is strongly recommended. Drive slowly at first and listen for any unusual noises. Checkpoint: if you hear clunking, re-check all bolts. A misaligned spacer can cause premature tire wear.
