Features

• Complete OEM+ assembly - arms arrive fully built with SuperPro polyurethane bushings and HD ball joints pre-installed, no press required
• Eliminates worn factory rubber bushings and tired ball joints in a single replacement, restoring precise steering response and front-end composure
• SuperPro polyurethane bushings outperform OEM rubber across the full operating range - unaffected by oils, extreme heat, and the compression cycles typical of off-road use
• HD uprated ball joints replace the OEM units for greater durability under the load demands of a 4WD lifestyle
• Arms are manufactured to OEM tolerances for factory-accurate geometry - a direct, no-modification fitment
• Eliminates the need for a press or bushing installation tools - saves workshop time and reduces labour costs

Product Description

The SuperPro TRC491 is a complete front upper control arm kit for the Toyota 4Runner, FJ Cruiser, Land Cruiser Prado 120/150, and Lexus GX470/GX460 - vehicles that share a common front independent suspension architecture and a common aging profile. As the upper control arms on these platforms accumulate years of off-road use, the OEM rubber bushings crack, harden, and lose their ability to control arm deflection, while the ball joints wear, introducing clunking, steering wander, and inconsistent alignment. SuperPro developed the TRC491 to address both issues in one bolt-in kit: each arm arrives with SuperPro polyurethane bushings pre-installed at all inner pivot points and a heavy-duty ball joint in place, so the replacement job becomes a direct swap rather than a multi-stage rebuild.

The TRC491 maintains OEM-equivalent geometry, making it the appropriate choice for vehicles running stock or near-stock ride height. The integrated SuperPro bushings resist the degradation of off-road conditions - heat cycling, compression under load, and exposure to oils and road chemicals - far more effectively than OEM rubber, while maintaining an acceptable NVH level for daily use. A front wheel alignment is required after installation. Arms and ball joints are covered by SuperPro's 3-Year Warranty; the polyurethane bushings are covered by a Lifetime Warranty.
