{"product_id":"rear-axle-assembly-with-4-10-gearing-and-g80-locking","title":"Rear Axle Assembly with 4.10 Gearing and G80 Locking","description":"The GMC GT5-G80 is a rear axle assembly that integrates a 4.10 gear ratio (GT5 RPO code) with an automatic locking rear differential (G80 RPO code).\n\nThe GT5-G80 axle is known for its compatibility with a range of GM vehicles. Fitment has been identified for specific model ranges including the 1988-2000 Chevrolet C2500 and 1998 GMC 3500 pickup trucks. It is also noted as being compatible with 2001-2006 Chevrolet Silverado and GMC Sierra 3500 HD Dually models, specifically the Cab \u0026amp; Chassis configurations, as well as the Suburban 2500.\n\nWhen considering this axle assembly, it's important to note that while it shares RPO codes GT5 and G80, direct bolt-up compatibility between different truck platforms (e.g., 2500 to 1500) may require further investigation into specific year and model variations. The 'G80 Locking rear-end' is a mechanical system that engages automatically when wheel slip is detected, providing a significant traction advantage in low-grip scenarios.\n\nApplications discussed in forums include potential swaps for 2008-2009 Silverado models, and it's noted that earlier S-10 and Blazer models might have also used these RPO codes, though specific fitment for those smaller platforms requires careful verification.","brand":"GMC","offers":[{"title":"Default Title","offer_id":52664224022840,"sku":"GT5-G80","price":350.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687547476.jpg?v=1784335446","url":"https:\/\/store.motormia.co\/products\/rear-axle-assembly-with-4-10-gearing-and-g80-locking","provider":"MOTORMIA","version":"1.0","type":"link"}
