Tacoma Lift Kit and Tire Size by Height

How much lift do you need for each tire size?

There is no single lift number that unlocks a tire size, because the Tacoma runs independent front suspension (IFS): the tire and the fender move together through the travel, so lift alone rarely stops a tire from rubbing at full compression. Lift buys you static clearance and a taller stance, while trimming does the real work of clearing a bigger tire when the suspension stuffs. The two levers you actually pull are ride height and how much you are willing to cut - and your generation changes both answers.

Can a leveling kit fit bigger tires, or do you need a real lift?

A leveling kit raises the front about 1.5 to 2 inches to remove the factory rake, so the truck sits flat and gains a little static gap between the tire and the fender. That is enough to make a 285/70R17 (a true 33 at about 32.7 inches) look right and clear while parked and driving straight. What a level does not do on an IFS truck is create clearance at full compression: when the suspension compresses over a bump or at full lock, the tire still travels up toward the same fender liner and cab mount it always did, because the strut sits higher but the travel window is unchanged.

• What a level buys you: a flatter stance, more static tire-to-fender gap, and an easy path to a 285/70R17 on a 4th-gen truck (near bolt-on) or on a lightly trimmed 3rd-gen truck.
• What it does not buy you: extra clearance when the suspension is fully stuffed - so 33s on a leveled 3rd gen still commonly need mud-flap removal and fender-liner trimming, and sometimes a cab-mount chop, to stop rub at full lock.
• It also does not add ground clearance under the axle the way a full suspension lift does, and it slightly steepens the front CV angle.

The practical takeaway: a leveling kit is a fine, low-cost way to run a 33 if you are ready to trim, but it is not a substitute for a taller coilover or spacer lift when you want a genuine ride-height increase, more droop for off-road, or the room for a 35.

Suspension lift vs body lift on a Tacoma's IFS - which does what?

The two lifts do very different jobs, and only one of them meaningfully helps tire fitment on a Tacoma. A suspension lift (spacers, or replacement coilovers and a rear block or new leaf pack) raises the frame off the axle and lower control arms, so a 3-inch suspension lift nets roughly 3 inches of ground clearance and repositions the whole suspension. A body lift instead spaces the cab and bed up off the frame with pucks; it raises the sheet metal but leaves the frame, axles, and suspension where they were, so it adds essentially no ground clearance.

Body lifts are common on solid-axle trucks to squeeze tire room, but they are uncommon and rarely recommended on the Tacoma. They do open up a little space between the tire and the body, but they leave a visible gap at the frame, need bumper and steering fixes, and do nothing for the IFS geometry that actually limits tire travel. For almost every Tacoma build, a suspension lift or leveling kit is the right tool, and trimming handles what lift cannot.

Do you need upper control arms, alignment, and new CV angles?

Once you go past roughly 2.5 inches of front lift, aftermarket upper control arms (UCAs) move from optional to strongly recommended. Stock UCAs run out of adjustment for caster and camber at that height and can contact the coil or bind at droop; a good UCA restores proper alignment angles, adds droop clearance, and usually upgrades the ball joint. Budget about $600 to $1,200 for a quality set, and plan on an alignment (roughly $100 to $200) after any suspension change - skipping it leads to fast, uneven tire wear.

• Caster and camber: lift pulls the front geometry out of spec; UCAs bring caster back for stable steering and let a shop set camber correctly.
• CV axle angle: lifting the front steepens the CV joint angle, which can add vibration and wear over time. Small lifts are usually fine; taller lifts benefit from a differential drop or CV-friendly design.
• Droop and contact: at full extension a lifted strut can let the coil or arm hit the stock UCA - another reason the aftermarket arm earns its place above ~2.5 inches.

How does the 4th gen make 35s easier?

The 2024+ 4th-gen Tacoma is markedly friendlier to 35s than the 3rd gen. Its wheel opening is more forgiving, and the frame is laid out so that the main obstacle up front is a bolt-on crash bracket (crash plate), not the cab mount. On a 4th gen, roughly a 3-inch lift plus a crash-plate delete is enough to run 35s without any permanent frame cutting. The crash plates come off with two bolts per side, free up several inches of clearance, and can be reinstalled at any time - a fully reversible modification.

The 3rd gen is a bigger project for the same tire. A 35 (315/70R17, sold as 35x12.50R17, about 34.4 inches) typically wants 4 to 6 inches of lift and permanent metalwork: a cab-mount chop (CMC), and often a body-mount chop (BMC), on top of liner and pinch-weld trimming. That is irreversible cutting, so it is worth being sure about the build before you commit. In short, 4th-gen 35s lean on reversible parts and lift; 3rd-gen 35s lean on lift plus the saw.

What does a lift and bigger tires cost, and when do you regear?

Costs swing widely with parts quality and whether you install yourself, but these ballparks help you budget. A leveling kit is the cheapest entry; a full coilover lift with UCAs and an alignment is a bigger jump; and a true 35 build with a regear is a multi-thousand-dollar project by the time everything is on the truck.

• Leveling kit: ~$150-500 in parts, or ~$300-700 installed with an alignment.
• 2-3 in suspension lift (spacers or coilovers): ~$1,000-2,500 in parts; ~$1,500-4,000 installed.
• Aftermarket UCAs: ~$600-1,200; alignment ~$100-200.
• Front and rear regear: ~$2,500-4,000 installed (you regear both axles to keep the front and rear ratios matched).
• 35-inch tires and wheels: varies widely by brand and size, on top of the above.

On gearing, bigger tires act like taller (numerically lower) axle ratios and sap acceleration and towing. A jump to 33s is usually livable without a regear, though a mild 4.56 or 4.88 helps if you tow or run a heavy tire. At 35s a regear is strongly recommended - commonly 4.88, or 5.29 for the biggest tires and heaviest use - to recover drivability. Run your tire diameter and stock ratio through a gear-ratio calculator to see the effective ratio and pick a target.
