It installs in under an hour, is adjustable, and can be easily removed, eliminating pinion angle changes, wheel hop, and differential deflection while increasing traction. It's made in-house from billet 6061 aluminum.\u003c\/p\u003e\u003cp\u003eThis is not a permanent modification — there's no drilling, cutting, or pressing required. Simply loosen and remove a couple of bolts and the kit installs in less than an hour. Aluminum bushings are included for both the front and rear differential mounting locations, with Grade 10.9 hardware and zinc-plated washers.\u003c\/p\u003e\u003cp\u003eNote: This is a race-only part that will increase NVH and gear noise. For street and competition use, Steeda's 555-4443 kit with urethane bushings is recommended instead. Does not fit GT350 or Mach 1. Due to changes in the OE subframe bushings, will not fit 2021 GT500s or 2022 Mustangs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProduct Benefits:\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eLimits IRS differential movement while increasing traction and eliminating wheel hop\u003cbr\u003eDesigned for the abuse of racing down the quarter mile\u003cbr\u003eEasily removable, not a permanent modification\u003cbr\u003e100% designed, manufactured, and made in the USA\u003cbr\u003eInstalls in one hour or less\u003c\/p\u003e","brand":"Steeda","offers":[{"title":"Default Title","offer_id":62382011875698,"sku":"555-4440","price":149.95,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0960\/6643\/7490\/files\/555-4440-bushing-irs-kit__05214.1681300018.jpg?v=1789816428","url":"https:\/\/hypermotive.com\/products\/steeda-mustang-race-differential-bushing-insert-system-aluminum-2015-2021","provider":"Hypermotive Performance","version":"1.0","type":"link"}
