Lifting your truck adds ground clearance and capability, but it also shifts suspension geometry, including the rear pinion angle on longitudinal engine layouts. The TRC497 lets you dial the pinion angle back in while upgrading to SuperPro's polyurethane bushings for improved durability, higher articulation, and a maintenance-free design that holds up to years of on-road and off-road use.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eHeavy duty adjustable design corrects rear pinion angle after a lift\u003c\/li\u003e\n\u003cli\u003eSuperPro polyurethane bushings replace worn factory rubber bushings\u003c\/li\u003e\n\u003cli\u003eImproves articulation for better off-road wheel travel\u003c\/li\u003e\n\u003cli\u003eMaintenance-free bushing design, no grease fittings required\u003c\/li\u003e\n\u003cli\u003eReduces deflection for more predictable rear axle control\u003c\/li\u003e\n\u003cli\u003eDirect bolt-on fitment at factory mounting locations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2010-2014\u003c\/td\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003eFJ Cruiser\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eYear Range\u003c\/th\u003e\n\u003cth\u003eMake\u003c\/th\u003e\n\u003cth\u003eModel\u003c\/th\u003e\n\u003cth\u003eTrim\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2010-2023\u003c\/td\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003e4Runner\u003c\/td\u003e\n\u003ctd\u003eSR5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2010-2023\u003c\/td\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003e4Runner\u003c\/td\u003e\n\u003ctd\u003eTRD Off-Road\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2010-2023\u003c\/td\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003e4Runner\u003c\/td\u003e\n\u003ctd\u003eLimited\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e2015-2023\u003c\/td\u003e\n\u003ctd\u003eToyota\u003c\/td\u003e\n\u003ctd\u003e4Runner\u003c\/td\u003e\n\u003ctd\u003eTRD Pro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eSpecifications\u003c\/h4\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eDetail\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eSuperPro\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMPN\u003c\/td\u003e\n\u003ctd\u003eTRC497\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSKU\u003c\/td\u003e\n\u003ctd\u003eSPRTRC497\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eUPC\u003c\/td\u003e\n\u003ctd\u003eNot published by manufacturer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePosition\u003c\/td\u003e\n\u003ctd\u003eRear, lower trailing arm, adjustable kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBushing Material\u003c\/td\u003e\n\u003ctd\u003eSuperPro polyurethane\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAdjustability\u003c\/td\u003e\n\u003ctd\u003eThreaded, adjustable length\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWarranty\u003c\/td\u003e\n\u003ctd\u003eManufacturer limited warranty against defects\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ch4\u003eWhat's Included\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e2 x SuperPro TRC497 adjustable lower trailing arms\u003c\/li\u003e\n\u003cli\u003eIntegrated polyurethane bushings\u003c\/li\u003e\n\u003cli\u003eMounting hardware\u003c\/li\u003e\n\u003cli\u003eInstallation instructions\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eAbout SuperPro\u003c\/h4\u003e\n\u003cp\u003eSuperPro has engineered performance suspension components since 1972, specializing in polyurethane bushings and suspension hardware designed to improve handling, durability, and control while maintaining daily drivability.

Even at stock ride height, upgrading to SuperPro's polyurethane bushings improves durability and articulation compared to the factory rubber bushings, which soften and wear over time.\u003c\/p\u003e\n\u003cstrong\u003eIs this a direct bolt-on replacement for the factory trailing arms?\u003c\/strong\u003e\n\u003cp\u003eYes.

The adjustable design and upgraded bushings allow for improved wheel travel and articulation compared to the factory trailing arms, which is especially useful on lifted trucks.\u003c\/p\u003e\n\u003cstrong\u003eHow do I know if my pinion angle needs correcting?\u003c\/strong\u003e\n\u003cp\u003eCommon signs include a vibration that increases with speed, driveline clunking, and premature wear on U-joints or the carrier bearing after installing a lift or leveling kit.\u003c\/p\u003e\n\u003cstrong\u003eCan this be installed with basic hand tools?\u003c\/strong\u003e\n\u003cp\u003eYes.
