2007 Toyota 4Runner Upper Control Arms

Upper Control Arms Engineered for 2007 4Runner Suspension Upgrades

Your 2007 Toyota 4Runner suspension needs components that survive lift kits and trail abuse. JBA upper control arms replace factory parts with tubular steel construction, CNC-machined Max 90 ball joints, and EZ Lube Bushings that extend service life through field maintenance. These UCAs are built similarly to the 2019 toyota 4runner control arm to give you additional caster correction on lifted rigs while maintaining steering geometry. Every kit ships with stainless hardware and installation instructions.

The Gen 4 4Runner platform shares front suspension architecture across 2003-2009 model years. JBA upper control arm geometry restores alignment specs after a 2-inch lift or larger, preventing premature tire wear and steering wander. Max 90 ball joints provide 90-degree articulation and are machined from 4140 chromoly steel. Unlike sealed OEM joints that fail without warning, these components rebuild in the field with replacement boots and bearings.

EZ Lube Bushings Replace Factory Control Arm Mounts

Factory upper control bushings bind under articulation and crack after UV exposure. JBA EZ Lube Bushings feature 8 individual grease ports and pressure relief valves that push contaminants out during maintenance intervals. Grease every 5,000 miles or after water crossings. This system eliminates the squeak and bind common in polyurethane bushings while outlasting rubber OEM mounts by years.

Each bushing housing is CNC-machined and accepts standard grease gun fittings. The pressure relief design prevents over-greasing. Field crews running jungle fleet operations grease these bushings monthly and report zero bushing failures across thousands of service hours. This is the durability you need when parts availability is measured in weeks, not hours.

Max 90 Ball Joints Outperform Sealed Factory Components

OEM ball joints seal grease inside a boot that tears on rock contact. Once contamination enters, the joint grinds itself to failure. JBA Max 90 ball joints use a rebuildable design with replaceable boots, bearings, and studs. When a boot tears on the trail, you replace the $12 boot instead of the $180 joint. Stud taper matches factory specifications for direct bolt-in fitment.

The 90-degree articulation range prevents bind at full droop, critical when running 33-inch tires on a lifted 2007 4Runner. Ball joint housings are forged, not cast, eliminating the porosity failures common in budget suspension parts. Toytec and other lift manufacturers specify JBA arms tubular construction for compatibility with their coilover and spacer kits.

Tubular Steel Construction Reduces Unsprung Weight

JBA upper control arms use DOM tubular steel, not stamped sheet metal. This drops 3 pounds per side compared to OEM cast arms while increasing strength. Lower unsprung weight improves suspension response over stutter bumps and washboard sections. Welds are TIG-finished and powder-coated in JBA Red for corrosion resistance in salt and mud environments.

The tubular design positions the ball joint for optimized caster gain. On a 3-inch lift, you gain 1.5 degrees of caster, improving high-speed stability and steering return. This correction eliminates the need for aftermarket caster shims or cam bolts. Alignment shops can dial in spec without workarounds.

Lifetime Structural Warranty Backs Every Part Included

JBA covers the tubular steel frame, ball joint housings, and bushing mounts under a lifetime structural warranty. Ball joints and bushings are wear items covered for the first year, then available as rebuild kits. This warranty has been honored since 2003 across four generations of upper control arm refinements. Gen 4.5 arms incorporate two decades of field feedback from expedition operators and trail builders.

If a weld cracks or a housing fails, JBA replaces the arm. No receipt required if you're the original buyer. This is the confidence that comes from engineering parts in-house and controlling the full manufacturing process. Thousands of JBA upper control arms run worldwide in conditions that destroy sealed, non-serviceable suspension components.

Install JBA Upper Control Arms on Your 2007 4Runner

Installation requires basic hand tools and a floor jack. Remove the factory upper control arm by unbolting the frame mounts and pressing out the ball joint taper. JBA UCAs bolt directly into OEM locations with no drilling or modification. Torque specs are included in the kit documentation. Plan 2-3 hours for a driveway install.

After installation, get a professional alignment within 50 miles. The adjustable cam bolts on JBA arms allow full caster and camber correction. Grease all 8 EZ Lube ports before the first trail run, then maintain every 5,000 miles or after submersion. Inspect ball joint boots every oil change and replace at the first sign of tearing.
