Together with the lowers, these arms set where the axle sits and how its pinion and caster angles change, and both shift when a Jeep is lifted. Replacement arms are how many modified Wranglers get their geometry back into range. It suits lifted JKs that see trail use as well as daily driving.\u003c\/p\u003e\u003cp\u003eOut-of-range geometry shows up as tires that wear on one edge, a car that pulls or wanders, and steering that does not return to center cleanly. Replacement trailing arms restore or correct that geometry, which often means better tire life and a more planted Wrangler.\u003c\/p\u003e\u003ch3\u003eKey features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eSuperPro part number TRC1186\u003c\/li\u003e\n\u003cli\u003eUpper trailing arm set\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e2007-2022 Jeep Wrangler Rubicon, Unlimited Sahara and Unlimited Rubicon\u003c\/li\u003e\n\u003cli\u003e2007-2017 Jeep Wrangler Sahara; 2007-2011 X and Unlimited X; 2009 X-S\u003c\/li\u003e\n\u003cli\u003e2010-2022 Jeep Wrangler Sport and Unlimited Sport; 2016-2022 Sport S and Unlimited Sport S; 2010-2021 Islander\u003c\/li\u003e\n\u003cli\u003e2010-2012 Unlimited Mountain; 2011 70th Anniversary; 2012 Unlimited; 2012-2015 Unlimited Altitude; 2014 Willys Wheeler; 2015 Unlimited Hard Rock\u003c\/li\u003e\n\u003cli\u003e2016 75th Anniversary and Unlimited Black Bear; 2017 Unlimited Smoky Mountain and Winter Edition\u003c\/li\u003e\n\u003cli\u003e2018 Jeep Wrangler JK Sport, Sport S, Sahara, Rubicon and Unlimited versions; 2018-2019 Unlimited Moab\u003c\/li\u003e\n\u003cli\u003e2021 Freedom, Islander and 80th Anniversary; 2021-2022 Willys, Willys Sport, Unlimited High Altitude, Sport Altitude, Sahara Altitude, Sahara 4xe, Rubicon 4xe and Rubicon 392; 2022 Unlimited High Tide\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eCheck your year, trim and drivetrain against the list above before ordering.\u003c\/p\u003e\u003ch3\u003eInstall notes\u003c\/h3\u003e\u003cp\u003ePlan an alignment after installing the new trailing arms.\u003c\/p\u003e","brand":"SuperPro","offers":[{"title":"Default Title","offer_id":68171884396845,"sku":"8QWZN","price":224.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/8295\/1469\/files\/107413f78c26b564ae5d39f59d23fae3L.jpg?v=1793835548","url":"https:\/\/lowerhq.com\/products\/superpro-07-17-jeep-wrangler-jk-2018-jeep-wrangler-jk-upper-trailing-arm-set-trc1186","provider":"LowerHQ","version":"1.0","type":"link"}
