{"product_id":"pontiac-ultra-serpentine-conversion-kit","title":"Pontiac Ultra Serpentine Conversion Kit","description":"The March Performance Pontiac Ultra Serpentine Conversion Kit provides a reliable, high-strength solution for upgrading engine drive systems. This system utilizes a serpentine belt design that prevents belt slippage and throwing, while CNC-machined 6061-T6 billet aluminum components offer increased wear resistance and a refined appearance for the engine compartment. All parts are finished with a maintenance-free clear or black powder coat to prevent the need for polishing in tight spaces.\n\nTechnical configuration requires a 1968 or newer balancer (without a v-groove) and a 1969 or newer 11-bolt water pump. The system features a spring-loaded tensioner with stainless steel rods and chrome moly ends for precise tensioning. Please note that for 1971-1974 applications, the return hose clocking will differ from original specifications but remains compatible with this setup. Users should also note the pump type distinction: keyed pumps were used through 1976, while press-fit pumps were used in 1977 and later models. This specific kit requires a 49.5-inch belt.","brand":"March Performance","offers":[{"title":"Default Title","offer_id":52662944661816,"sku":"MAR-13100-100x-105","price":495.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687502861.jpg?v=1784321924","url":"https:\/\/store.motormia.co\/products\/pontiac-ultra-serpentine-conversion-kit","provider":"MOTORMIA","version":"1.0","type":"link"}
