Best Upper Control Arms for 95-04 Tacoma & 4Runner

Adjustable upper control arms are the single most important alignment upgrade for a lifted 95–04 Toyota Tacoma or 96–02 4Runner, and the SPC Performance 35460 pair is the arm most first-gen owners end up buying. The moment you add a 2 to 3-inch front lift — whether it comes from a leveling spacer, a coil spacer, or a full ICON coilover — the factory suspension geometry falls out of spec. Caster drops, the front end wanders at highway speed, the inner tire edges wear fast, and the stock upper arm starts contacting the coil spring at full droop. This guide compares the best upper control arms and lift options we stock for the first-gen Tacoma and third-gen 4Runner at NLP Performance in Tampa, FL, with real part numbers, adjustment ranges, and prices so you can build the front end once and do it right.

Why Does a Lifted 95-04 Tacoma or 96-02 4Runner Need Adjustable Upper Control Arms?

A lifted first-gen Tacoma needs adjustable upper control arms because lifting the front end reduces caster and pushes camber negative, and the factory cam bolts do not have enough range to bring those angles back into spec. The 1995–2004 Tacoma and 1996–2002 4Runner share the same independent front suspension (IFS) with a coil-over shock and a stamped-steel upper control arm. From the factory these trucks run only a few degrees of positive caster. Add 2 to 3 inches of front height and you lose roughly 1.5 to 2.5 degrees of caster, which is what makes a leveled Tacoma feel darty, follow road grooves, and refuse to self-center after a turn.

There are three specific problems adjustable arms solve. First, caster restoration — a quality aftermarket arm builds caster back in and lets an alignment tech dial it further, which brings back straight-line stability. Second, clearance — a taller ride height cycles the suspension into a range where the stock arm can contact the coil spring at full droop; a purpose-built arm relocates the ball joint and clears it. Third, tire rub — running maximum positive caster moves the wheel forward in the well, which is exactly what you want when you fit a 33-inch tire on a first-gen truck.

This is not optional on a serious build. ICON explicitly states that its extended-travel coilovers for this platform require aftermarket upper control arms to use the full wheel travel — the arm is what unlocks the droop the longer shock is capable of. If you are lifting a first-gen Tacoma or third-gen 4Runner past a mild level, budget for the arms in the same build.

Top Pick: SPC Performance 35460 Adjustable Upper Control Arms

The SPC Performance 35460 is a bolt-in adjustable upper control arm pair engineered specifically for the 1996–2002 Toyota 4Runner and 1995–2004 Toyota Tacoma. It uses SPC's patented pivoting ball joint to deliver 0 to +4° of caster and ±2° of camber adjustment, with an extra +1° of caster built into the casting for these first-gen trucks. The upgraded greaseable ball joint offers 80° of articulation, and SPC's SpecRide bushings free-pivot to give you maximum droop travel without binding — while keeping factory-smooth ride quality on the street.

What Are the Best Lift and Leveling Options for the First-Gen Tacoma?

The best lift setup depends on your budget and how far you plan to go. A strut or coil spacer levels the truck for under $300 and keeps the factory ride, an ICON 2.5 Series coilover gives you 0 to 3 inches of adjustable lift plus a genuine performance shock, and a diff-drop kit protects your CV axles once you go past a mild level. Below are the front-end options we stock for the 95-04 Tacoma and 96-02 4Runner, from budget to premium.

ICON V.S. 2.5 Series Coilover Kit (0-3 inch Lift)

The ICON 58610 is a vehicle-specific 2.5-inch internal-reservoir front coilover that replaces the tired factory strut with a rebuildable performance unit. It offers 0 to 3 inches of adjustable ride height, uses ICON's larger 2.5-inch body and increased piston area for more travel and control, and rides better on-road than the stock shock while soaking up washboard off-road. The extended-travel version (ICON 58615) steps up to a 700 lbs/in spring rate to carry the weight of an aftermarket bumper or winch and is recommended with a 33 x 11.50-inch tire — but it requires adjustable upper control arms to use its full travel.

Skyjacker 1998-2004 Tacoma Front Leveling Kit

If you want the leveled stance without spending coilover money, the Skyjacker front leveling kit raises the nose roughly 2 inches to match the rear and keeps the factory ride. At $298.74 it is the middle-ground option: more than a bare spacer, less than a coilover. Early 1995-1997 trucks use a dedicated Skyjacker front leveling kit ($161.22), so match the kit to your exact year. Even at this modest height a leveled first-gen truck benefits from the caster correction that adjustable UCAs provide.

MaxTrac 2.5 inch Front Leveling Strut Spacers (Budget Pick)

The cheapest way to level a first-gen Tacoma is a strut spacer, and the MaxTrac 836925 delivers 2.5 inches of front lift for $109.81 (down from $127.15). It bolts on top of the factory coil-over, fits both 2WD and 4WD 6-lug trucks from 1995.5 to 2004, and gets you a level stance and room for a slightly larger tire without touching the spring. It is the entry point — but any spacer lift changes your alignment, so plan on adjustable arms and an alignment if you push the height.

Here is how the front-end options for the 95-04 Tacoma and 96-02 4Runner stack up side by side. The SPC arms are the alignment fix; the coilovers and spacers set your height. Most complete builds combine one height option with the SPC UCAs.

What Supporting Mods Should Go With a Front Lift?

Two supporting parts turn a good front lift into a reliable one. Once you clear 3 inches, a diff-drop kit re-angles the front differential to keep your CV axles running at a safe angle and stops the boots and joints from wearing out early. And because the SPC arms and ICON coilovers unlock more front droop, matching rear shocks keep the back of the truck controlled instead of topping out.

ICON Diff Drop Kit

The ICON 51050 diff-drop kit lowers the front differential to correct CV-axle plunge angle on lifted 96-04 Tacoma, 96-02 4Runner, and 00-06 Tundra models. At $128.57 with 15 in stock, it is cheap insurance against premature CV failure on any build running 3 inches or more of front lift.

ICON Rear 2.0 Series Aluminum Shocks

To match the upgraded front, the ICON 56502 rear 2.0 Series aluminum shocks are monotube units tuned for 0 to 1.5 inches of rear lift on the 96-04 Tacoma 4WD. At $195.65 with 9 in stock, they finish the job by controlling the rear the same way the 2.5 coilovers control the front.

How Hard Is It to Install Upper Control Arms on a First-Gen Tacoma?

Installing adjustable upper control arms on a 95-04 Tacoma is a moderate driveway job that most DIYers finish in about 2 to 3 hours per side with hand tools. You support the frame, unload the front suspension, remove the two frame bolts and the upper ball-joint nut, swap the arm, and torque everything to spec. The one non-negotiable step is a professional alignment afterward — the arms are worthless until a technician sets caster and camber back to spec. In our Tampa, FL shop we set maximum positive caster on lifted first-gen trucks to bring back straight-line stability and push the tire forward for clearance.

If you are pairing the arms with a coilover or leveling kit, install the height change first so the alignment tech is working with the final ride height. Browse the full NLP suspension collection or our lift kits to build the complete package in one order.
