{"product_id":"wavetrac-02j-limited-slip-front-differential","title":"Wavetrac 02J Limited Slip Front Differential","description":"The Wavetrac 02J Limited Slip Front Differential is engineered for MkIV Volkswagen Golf, Jetta, Bora, and Beetle models utilizing the 02J 5-Speed Manual Transmission. This performance differential drives both wheels for improved acceleration and faster cornering, offering a significant upgrade over stock open differentials. Its unique wave design center pack provides an enhanced no-load bias ratio, meaning it maintains grip even under zero or near-zero torque conditions, a common weakness in other torque-biasing differentials. This patented design automatically increases the bias ratio when needed and seamlessly reverts to its nominal ratio for optimal drivability.\n\nConstructed in the USA with high-strength 9310 alloy steel gears and exclusively made ARP® fasteners, the Wavetrac differential is built for durability. The diff bodies are machined from case-hardened steel billet. The internal gears are optimized for strength and oil film retention, and the side gear\/axle interface is designed with maximum material thickness for high power levels.\n\nFurther customization is possible with interchangeable friction plates, sold separately. These plates allow users to fine-tune the differential's response based on applied torque load, tailoring performance to specific needs. The standard configuration includes carbon-fiber bias plates for excellent all-around performance.","brand":"WAVETRAC","offers":[{"title":"Default Title","offer_id":52867519512888,"sku":"10.309.180WK","price":975.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687952018.webp?v=1787911620","url":"https:\/\/store.motormia.co\/products\/wavetrac-02j-limited-slip-front-differential","provider":"MOTORMIA","version":"1.0","type":"link"}
