{"product_id":"helical-limited-slip-differential-for-fiat-c510","title":"Helical Limited-Slip Differential for Fiat C510","description":"The Blackline HLF150 helical limited-slip differential is engineered for Fiat models featuring the C510 gearbox, serving as a direct performance enhancement over the factory open differential. Its intelligent torque distribution between driven wheels significantly boosts traction, enhances cornering stability, and optimizes power delivery, making it well-suited for spirited road driving and track use.\n\nUnlike conventional clutch-type differentials, the HLF150 utilizes a precision helical gear torque-biasing mechanism. This design bypasses clutch plates and their inherent wear, resulting in smooth, progressive engagement, minimal noise, and virtually no maintenance requirements. The differential actively redirects torque to the wheel with the most grip, drastically improving acceleration traction, especially during corner exits or in low-grip scenarios.\n\nConstructed from high-strength 8620 alloy steel, the HLF150 is built for durability and longevity. Its 5:1 torque bias ratio allows it to transfer up to five times more torque to the wheel with superior traction, maintaining predictable and stable handling even under significant traction imbalances. The unit is a direct replacement for the original differential and is compatible with the C510 5-speed gearbox found in various Fiat and Abarth models, including the 500 Abarth, Bravo\/Brava variants, Coupe models, Punto generations, and specific Uno models.\n\nKey advantages over a standard open differential include improved acceleration traction, reduced inside wheel spin during cornering, faster response than viscous LSD systems, progressive engagement without harsh locking, and quiet operation suitable for both road and track use. Installation is a direct swap, though replacement of gaskets\/seals and two differential bearings may be necessary if the originals cannot be reused. The LSD does not require special oil; OE differential oil is suitable.","brand":"Blackline","offers":[{"title":"Default Title","offer_id":52687144911160,"sku":"HLF150","price":815.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/660679937.webp?v=1784880828","url":"https:\/\/store.motormia.co\/products\/helical-limited-slip-differential-for-fiat-c510","provider":"MOTORMIA","version":"1.0","type":"link"}
