{"product_id":"helical-gear-differential-21","title":"Helical Gear Differential","description":"Designed from the ground up, it incorporates advanced gear tooth forms optimized for strength and improved oil film retention, resulting in a smaller yet more durable gear package. Its design pays close attention to the side gear\/axle interface, maximizing material thickness in this critical area for high-power applications.\n\nThis differential is manufactured in the USA by Autotech Driveline and is distinguished by its patented technology that actively mitigates wheelspin. During zero axle load conditions, the Wavetrac cam device generates internal load, ensuring drive is maintained on the gripping wheel rather than allowing it to act like an open differential. The internal gears are constructed from high-strength 9310 alloy steel, and the diff bodies are precisely machined from case-hardened steel billet.\n\nThis specific Wavetrac differential (Part # 48.309.185WK) is designed to fit the Mercedes HAG215 rear axle. It is compatible with a range of AMG models, including the E55\/E63 W211, E63 W212, C63 W204, C55 W203, SL55\/SL65 R230, CLS63, SL600 R230, CLK63\/CLK55\/CLK500 ('04+) W209, and SLK55 R171.\n\nAll Wavetrac differentials come with a transferable, Limited Lifetime Warranty, underscoring the brand's commitment to quality and durability.","brand":"Wavetrac","offers":[{"title":"Default Title","offer_id":52872134689080,"sku":"42.309.185WK","price":1395.0,"currency_code":"USD","in_stock":true}],"url":"https:\/\/store.motormia.co\/products\/helical-gear-differential-21","provider":"MOTORMIA","version":"1.0","type":"link"}
