They are constructed from 0.120 inch wall cold rolled steel tubing that is boxed for maximum strength and to eliminate flex, and they use fluted, greasable polyurethane bushings on both ends in place of the soft stock rubber bushings. Keeping the tires planted more firmly improves traction and gives a more predictable, better handling car. The arms are powder coated gloss black for a long lasting finish and are sold as a pair.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eSpecifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eType: lower boxed trailing arms, sold in pairs\u003c\/li\u003e\n\u003cli\u003eConstruction: 0.120 in wall cold rolled boxed steel tubing\u003c\/li\u003e\n\u003cli\u003eBushings: fluted, greasable polyurethane on both ends\u003c\/li\u003e\n\u003cli\u003eFinish: gloss black powder coat\u003c\/li\u003e\n\u003cli\u003eInstall: bolt-in\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003cli\u003ePart number: 5221\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eVehicle Applications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e1979 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1980 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1981 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1982 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1983 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1984 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1985 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1986 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1987 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1988 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1989 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1990 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1991 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1992 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1993 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1994 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1995 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1996 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1997 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1998 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1999 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e2000 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e2001 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e2002 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e2003 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e2004 Ford Mustang\u003c\/li\u003e\n\u003cli\u003e1979 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1980 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1981 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1982 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1983 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1984 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1985 Mercury Capri\u003c\/li\u003e\n\u003cli\u003e1986 Mercury Capri\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003ca href=\"https:\/\/d32vzsop7y1h3k.cloudfront.net\/18018d84476951bcef059cb7efd04f25.PDF\"\u003eInstallation Instructions\u003c\/a\u003e\u003c\/p\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\u003ch5\u003eWhat does the QA1 5221 trailing arm kit include?\u003c\/h5\u003e\u003cp\u003eIt includes two lower boxed trailing arms with greasable polyurethane bushings, sold as a pair.\u003c\/p\u003e\u003ch5\u003eWhat vehicles do the 5221 trailing arms fit?\u003c\/h5\u003e\u003cp\u003eThey fit 1979-2004 Ford Mustang and 1979-1986 Mercury Capri.\u003c\/p\u003e\u003ch5\u003eAre these a bolt-in installation?\u003c\/h5\u003e\u003cp\u003eYes.
