Lifting your Toyota Tacoma 3.5 V6 transforms its capability on trails, improves ground clearance, and gives it a commanding stance. But a successful lift requires careful planning, the right components, and meticulous installation. This guide expands on the essential steps, tire fitment rules, and pro tips to help you avoid common mistakes and get the most out of your Tacoma’s new suspension.

Understanding Lift Kits: Body vs. Suspension

Before buying parts, you need to know the difference between the two main lift types and how they affect your Tacoma.

Body Lift Kits

A body lift uses polyurethane spacers between the frame and body to raise the cab and bed. It does not change suspension geometry, ground clearance at the axles, or ride quality. Body lifts typically provide 1–3 inches of lift and are a budget-friendly way to fit larger tires. However, they offer no improvement in off-road articulation or shock travel.

Suspension Lift Kits

Suspension lifts modify the actual suspension components—coil springs, struts, control arms, and sometimes the rear leaf springs or shackles. These lifts improve wheel travel, ride comfort, and ground clearance at the differentials. They range from simple leveling spacers (1.5–2.5 inches) to long-travel systems (4+ inches) that require new upper control arms, differential drops, and brake line extensions.

For most Tacoma 3.5 V6 owners who plan moderate off-roading, a 2–3 inch suspension lift paired with quality shocks is the sweet spot. It clears 33-inch tires without major NVH (noise, vibration, harshness) changes, and it maintains good on-road manners.

Choosing the Right Lift for Your Driving Style

Your choice should align with how you use the truck. Consider these factors:

  • Daily driver with occasional dirt roads: A 2-inch front leveling spacer or a budget coilover lift (like Bilstein 5100s) is sufficient. This clears 32–33-inch tires and retains factory ride quality.
  • Moderate off-road (trails, camping): A 2.5–3-inch complete suspension lift with aftermarket upper control arms (to correct alignment) and new rear leaf packs or add-a-leafs. This handles 33–34-inch tires and improves articulation.
  • Hardcore rock crawling or desert running: Long-travel suspension with 4+ inches of lift, custom coilovers, bypass shocks, and significant cutting or trimming. Expect to run 35-inch tires or larger, which requires regearing and axle upgrades.
  • Budget and warranty: Entry-level spacers are inexpensive but don’t improve performance. Premium kits from brands like 4x4 Parts or Toytec offer valving matched to the spring rate and come with warranties.

Tools and Preparation

Installing a lift kit is a medium-difficulty DIY job. Gather these tools before you start:

  • Floor jack and four jack stands (rated for your truck’s weight)
  • Metric socket set (10mm to 24mm) with swivels and extensions
  • Wrenches (combination and ratcheting)
  • Torque wrench (ft-lb and in-lb ranges)
  • Spring compressor (for coilover disassembly, if not using pre-assembled struts)
  • Impact wrench (saves time, especially on lower control arm bolts)
  • Ball joint separator or pickle fork
  • Thread locker (Loctite blue or red, depending on location)
  • Disposable gloves, safety glasses, and penetrating oil for rusty bolts

Safety note: Always support the vehicle on jack stands placed under the frame rails, not on the axle or suspension control arms. Never work under a truck supported only by a jack.

Step-by-Step Installation: Front Suspension (Tacoma 3.5 V6 4WD)

This procedure is generic for most 2–3 inch lift kits. Always follow the specific instructions that come with your kit. The Tacoma’s front suspension uses a double-wishbone design with coilover struts.

1. Preparation and Disassembly

Park on level ground, apply the parking brake, and chock the rear wheels. Loosen the front lug nuts while the truck is on the ground. Jack up the front of the truck and place jack stands under the frame rails behind the lower control arm mounts. Remove the front wheels.

2. Disconnect Sway Bar and Brake Lines

Unbolt the front sway bar end links from the lower control arms. You may need to loosen the sway bar frame brackets to allow droop. Also unbolt the brake line brackets from the frame (do not open the hydraulic system) and the ABS sensor wire clips so they don’t stretch when the suspension droops.

3. Remove the Lower Control Arm and Coilover Assembly

Support the lower control arm with a jack. Remove the lower shock bolt and the upper strut nuts (usually under the hood, at the strut tower). Slowly lower the jack to decompress the spring. If your kit replaces the entire coilover, you can now remove the assembly. For spacer lifts, you’ll need to compress the spring and add the spacer on top of the strut.

Note: The Tacoma’s front knuckle has a ball joint taper that can make separation difficult. Use a ball joint separator or tap the knuckle with a hammer to release it. Do not pry against the rubber boot.

4. Install New Components

If using new coilovers, pre-assemble them per the manufacturer’s spring perch settings. Install the new strut assembly, hand-tightening the top nuts. Then raise the lower control arm with the jack and attach the lower bolt. Torque all fasteners to spec with the vehicle’s weight on the suspension (see below for “settling the suspension”). Reattach the sway bar end links and brake line brackets.

5. Repeat for Driver Side and Rear

The driver side is identical. For the rear suspension (leaf spring or coil spring depending on year), you’ll typically replace the rear shocks, add-a-leaf or install new leaf packs, and possibly use lift shackles. Follow the same principle of supporting the axle, removing U-bolts, and carefully lowering the spring.

Setting the Suspension and Final Torque

After all four corners are loosely assembled, it’s critical to settle the suspension before final torquing. With the truck back on its wheels but still on jack stands (axles unsupported), lower the vehicle so the tires are on the ground and the suspension is at ride height. Now torque the following to manufacturer specifications:

  • Lower control arm bolts
  • Upper strut nuts
  • Sway bar end links
  • Rear U-bolts (on leaf spring trucks)
  • Shock bolts

If you tighten these bolts when the suspension is hanging, the bushings will be twisted at ride height, leading to premature wear and harsh ride quality.

Alignment and Post-Installation Checks

Any lift changes the front alignment angles. You must get a professional alignment after installation. Expect the technician to adjust camber and toe. For lifts over 2 inches, aftermarket upper control arms are usually required to bring camber back into spec. Without them, you may have excessive positive camber and poor tire wear.

Check everything after a short test drive:

  • Recheck all bolts for torque after 100 miles.
  • Inspect brake lines for any rub points.
  • Listen for clunks or creaks – signs of loose fasteners or misaligned components.
  • Verify the headlight aim – a lift points the beams higher, so you’ll need to adjust them down.

Tire Fitment: Sizes, Offset, and Avoiding Rub

Choosing the right tire size and wheel specs is just as important as the lift itself. The following recommendations are for the Toyota Tacoma 3.5 V6 (3rd gen, 2016–2023) with a 2–3 inch lift.

Maximum Tire Sizes

  • 2-inch leveling lift (front spacer only): 32–33 x 11.5–12.5 on factory wheels (with some trimming of the front bumper and fender liner for 33s).
  • 2.5–3 inch suspension lift: 33 x 12.5 on stock wheels or 34 x 10.5 with aftermarket wheels (requires aggressive trimming and possibly a body mount chop for 34s).
  • 3+ inch lift with aftermarket control arms: 35 x 12.5 is possible but requires a Cab Mount Chop (CMC), pinch weld flattening, and sometimes a “chop kit” for the front bumper. Regearing to 4.56 or 4.88 is strongly recommended.

Wheel Offset and Backspacing

To prevent rubbing, pay attention to the wheel’s offset and backspacing. The Tacoma factory wheels typically have +30mm to +35mm offset. For lifted trucks, moving to a more negative offset (e.g., 0mm to -15mm) pushes the tires outward, increasing stability and clearance to the upper control arm, but it also pushes the tire into the rear of the front fender at full turn. A safe aftermarket spec is:

  • 17x8.5 or 17x9 wheel with 0mm to -10mm offset for 33-inch tires.
  • 17x9 with -12mm to -18mm offset for 35s (requires trimming and CMC).

Always test fit a front wheel and cycle the steering lock-to-lock before mounting tires. This simple step can save you from buying the wrong wheels. For detailed fitment discussions, forums like TacomaWorld have massive threads with real user photos and tire sizes.

Trimming and Modifications

Even with the right lift and offset, you may still need to trim. Common areas to modify:

  • Front bumper lower valance – most 33-inch tires require trimming the plastic valance below the headlights.
  • Fender liner push-pins – reposition or cut the inner fender liner to prevent rubbing at full lock.
  • Body mount chop – for 35-inch tires, the rear of the front wheel well (the body mount) must be cut and boxed-in. This is a significant fabrication job.

Common Mistakes and How to Avoid Them

Based on countless forum posts and shop experience, here are the top mistakes first-time lifters make on the Tacoma 3.5 V6:

  • Skipping alignment: Drives poorly, eats tires, and can damage ball joints.
  • Over-torquing or under-torquing bolts: Always use a torque wrench; lubricate threads if specified.
  • Not replacing upper control arms for lifts over 2.5 inches: Stock UCA’s ball joint angle becomes extreme, leading to premature failure and poor alignment range.
  • Ignoring brake line length: At full droop, stock brake lines can be taut and damaged. Many lift kits include drop brackets or extended lines – install them.
  • Choosing tires too large for the lift: Rather than trim aggressively, stick to a 33-inch tire on a 3-inch lift for a clean look that works on trails.

Post-Installation Maintenance and Longevity

After lifting, your Tacoma requires some extra care:

  • Re-torque all suspension bolts after 100 miles, then annually.
  • Check shock boots and bushings for mud or damage regularly.
  • Lubricate aftermarket UCA’s polyurethane bushings if applicable.
  • Monitor tire wear – uneven wear may indicate lost alignment due to settling.
  • Inspect CV axle shafts – a lift increases the CV angle, which can accelerate boot wear. If you hear clicking at full turn, replace the axle before it fails.

Final Thoughts

Lifting your Toyota Tacoma 3.5 V6 is a rewarding project that unlocks the truck’s true off-road potential. But it’s not just about adding a spacer and bigger tires—it’s a complete system that includes correct alignment, possibly new control arms, attention to brake lines, and committing to the routine maintenance that follows. By choosing a lift tailored to your driving, using the right tools, and following proper procedures for torque and suspension settling, you’ll build a reliable lifted Tacoma that handles as well on the highway as it does on the trail.
