This mechanical locker delivers full power to both wheels when you need it, giving your truck true traction no matter the terrain. Whether you're launching at the strip, crawling over rocks, or pulling heavy loads through mud, the Grizzly keeps your axles locked in and pushing forward. Unlike selectable lockers that require air lines or electronics, this system engages automatically and mechanically, so you’re never left waiting for something to activate. And when you're turning on pavement or navigating tight corners, it backs off just enough to allow smooth, street-friendly operation. Built tough for daily drivers, work trucks, and off-road rigs alike, it's the kind of part you install once and trust for the long haul. If traction and durability are high on your list, this locker is one of the best investments you can make for your drivetrain.\u003c\/p\u003e\n\u003ch4\u003eEngineered For Strength With A Purpose Built Design\u003c\/h4\u003e\n\u003cp\u003eThe Yukon YGLGM11.5-30 Grizzly Locker is designed specifically for 11.5-inch, 30-spline axles found in 2001–2018 GM Silverado and Sierra trucks, as well as 2003–2018 Dodge Ram 2500 and 3500 models. At its core is an 8620 alloy carrier paired with 8620 heat-treated internals, a combination known for handling high torque and resisting fatigue under extreme conditions. This locker uses a patented internal design that improves reliability by eliminating common failure points found in older locker systems. It engages both wheels fully under load, providing 100 percent torque transfer in straight-line situations while still allowing for smooth disengagement during turns. The mechanical engagement system means no airlines, wires, or switches, just dependable, automatic operation that works every time. Assembled in the USA, this unit is backed by a 1-year warranty against manufacturer defects, offering confidence both on and off the road. From drag racing to heavy towing, this Grizzly Locker is a proven solution for serious traction and drivetrain strength.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e Fitment: \u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eChevrolet Silverado 2500 HD (2001-2018)\u003c\/p\u003e\n\u003cp\u003eChevrolet Silverado 2500 (2001-2004)\u003c\/p\u003e\n\u003cp\u003eChevrolet Silverado 3500 Classic (2007-2007)\u003c\/p\u003e\n\u003cp\u003eChevrolet Silverado 3500 HD (2007-2018)\u003c\/p\u003e\n\u003cp\u003eChevrolet Silverado 3500 (2001-2006)\u003c\/p\u003e\n\u003cp\u003eDodge Ram 3500 (2003-2010)\/Dodge Ram 2500 (2003-2010) \u003c\/p\u003e\n\u003cp\u003eGMC Sierra 3500 (2001-2006)\u003c\/p\u003e\n\u003cp\u003eGMC Sierra 3500 HD (2007-2018)\u003c\/p\u003e\n\u003cp\u003eGMC Sierra 2500 HD (2001-2018)\u003c\/p\u003e\n\u003cp\u003eGMC Sierra 2500 (2001-2004)\u003c\/p\u003e\n\u003cp\u003eGMC Sierra 3500 Classic (2007-2007)\u003c\/p\u003e\n\u003cp\u003eGMC Sierra 2500 HD Classic (2007-2007)\u003c\/p\u003e\n\u003cp\u003eRam 3500 (2011-2018)\/Ram 2500 (2011-2018)\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eNotes:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eConfirm your axle is 11.5‑inch with 30‑spline setup\u003c\/li\u003e\n\u003cli\u003eMechanical locker engages automatically, no electronics needed\u003c\/li\u003e\n\u003cli\u003eDesigned for serious street, off‑road and drag use\u003c\/li\u003e\n\u003cli\u003ePatent‑pending internal design increases durability\u003c\/li\u003e\n\u003cli\u003eUses 8620 heat‑treated internals and forged case\u003c\/li\u003e\n\u003cli\u003eProvides 100% torque to both tires when locked\u003c\/li\u003e\n\u003cli\u003eAllows disengagement during turns for safer street driving\u003c\/li\u003e\n\u003cli\u003eAssembled in the USA for quality assurance\u003c\/li\u003e\n\u003cli\u003eBacked by Yukon’s warranty covering defects and collateral damage\u003c\/li\u003e\n\u003cli\u003eMust match vehicle fitment list and verify differential type before install\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Yukon Gear And Axle","offers":[{"title":"Default Title","offer_id":68059954020625,"sku":"YUK-YGLGM11.5-30","price":1806.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0692\/0477\/1089\/files\/YGLGM115-30_1.jpg?v=1794702854","url":"https:\/\/gautoparts.com\/products\/01-18-gm-2500-3500hd-03-10-dodge-ram-2500-3500-yukon-gear-grizzly-locker-for-115-30spline-axles","provider":"Guaranteed Auto Parts","version":"1.0","type":"link"}
