{"product_id":"9-irs-conversion-kit-w-s-trac-differential","title":"9\" IRS Conversion Kit w\/ S-Trac Differential","description":"The GForce 9” IRS conversion kit is engineered to enhance the strength and reliability of your vehicle's differential, especially in high-power scenarios. It replaces the OEM differential with a robust assembly featuring a Strange Engineering aluminum center section and a Strange S-Trac differential, capable of handling significant torque while preserving the factory IRS setup. The kit includes a GForce fabricated rear housing, front mount, Renegade Axles (with an option to upgrade to Outlaw Axles), and a 4-inch aluminum driveshaft designed to bolt directly to OEM-style transmissions. Gear set options include 3.0, 3.25, 3.50, 3.70, 3.89, and 4.11.\n\nInstallation may require modifications for driveshaft clearance, particularly around exhaust components or the differential housing, due to the lower pinion height and larger driveshaft diameter. Clearance around suspension components, such as shocks and axle boots, should also be checked by the installer. Some aftermarket shocks or control arms may present fitment challenges. If CV boots are too close to suspension parts, low-profile boots are available as an upgrade, though they reduce available axle angle and are not ideal for lowered vehicles or those with high axle angles. This kit is not guaranteed to fit with other aftermarket products.\n\nIt is important to note that no driveline component is \"bomb-proof.\" GForce does not assign a power rating due to the numerous variables affecting driveline components. The customer is responsible for proper installation and the lifespan of the components, which are subject to wear and fatigue based on driving style and performance demands. CV joints are wear items and can be serviced, as can individual axle components, to extend their life. This kit is specifically designed for 2015-2026 Ford Mustangs.","brand":"GForce Engineering","offers":[{"title":"Default Title","offer_id":52688552034616,"sku":"FOR10904A","price":9338.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/664202087.webp?v=1784890892","url":"https:\/\/store.motormia.co\/products\/9-irs-conversion-kit-w-s-trac-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
