By intelligently distributing torque between the driven wheels, it improves traction, cornering stability and power delivery, making it ideal for fast road and track use.\u003c\/p\u003e\n\u003cp\u003eUnlike clutch-type differentials, this LSD uses a precision helical gear torque-biasing design, eliminating clutch plates and the associated wear. This results in smooth, progressive engagement with minimal noise and virtually no maintenance requirements.\u003c\/p\u003e\n\u003cp\u003eIt is a torque-biasing differential that automatically transfers torque to the wheel with the most available grip. This significantly improves traction during acceleration, particularly when exiting corners or driving in low-grip conditions.\u003c\/p\u003e\n\u003cp\u003eInside the differential, parallel-axis helical gears generate internal thrust forces proportional to the applied torque. These forces create resistance within the differential housing, allowing torque to be directed to the wheel with greater traction while maintaining smooth operation during normal driving.\u003c\/p\u003e\n\u003cp\u003eWith a 5:1 torque bias ratio, the Blackline LSD can transfer up to five times more torque to the wheel with the most grip. This allows the differential to handle significant traction imbalances while maintaining predictable and stable handling. In rare situations where one wheel has completely lost traction, techniques such as light braking can help the differential redistribute torque effectively.\u003c\/p\u003e\n\u003cp\u003eManufactured from high-strength 8620 alloy steel, it is built for durability and long service life. Precision machining and heat treatment ensure it can withstand high torque loads in demanding performance environments.\u003c\/p\u003e\n\u003cp\u003eCompared to a standard open differential, the Blackline LSD provides several key advantages:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eImproved traction under acceleration\u003c\/li\u003e\n\u003cli\u003eReduced inside wheel spin when cornering\u003c\/li\u003e\n\u003cli\u003eSmoother and faster response than viscous LSD systems\u003c\/li\u003e\n\u003cli\u003eProgressive engagement without harsh locking\u003c\/li\u003e\n\u003cli\u003eNo clutch plates to wear or require servicing\u003c\/li\u003e\n\u003cli\u003eQuiet operation suitable for road and track use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe differential is designed as a direct replacement for the original unit, fitting the vehicles listed below.\u003c\/p\u003e","brand":"Blackline","offers":[{"title":"Default Title","offer_id":56248657609079,"sku":"MLR.DAA","price":524.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0556\/0703\/4172\/files\/hlf031_1_webp.webp?v=1769444697","url":"https:\/\/mattlewisracing.co.uk\/products\/blackline-hlf031-mazda-mx5-nc-mk3-helical-gear-lsd","provider":"Matt Lewis Racing","version":"1.0","type":"link"}
