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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e","brand":"Superpro","offers":[{"title":"Default Title","offer_id":53500598812991,"sku":"SPRTRC491","price":259.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0832\/7308\/9343\/files\/4de6f8759b82832c1615931879ce0aecL.jpg?v=1780453223","url":"https:\/\/wcaperformance.com\/products\/superpro-2010-lexus-gx460-premium-front-upper-standard-alignment-upper-control-arm-kit","provider":"WCA Performance","version":"1.0","type":"link"}
