Unlike a mechanical locker, the YDGGM11.5-30-1 provides smooth yet aggressive traction in a wide range of conditions by using composite clutch packs and 4320 chromoly forged spider gears in a proven 4-pinion design. The result is a limited slip that fits all gear ratios, handles the heavy loads of Duramax and Cummins-powered trucks, and delivers confident traction without the noise or handling characteristics of full mechanical lockers. Whether you are towing heavy, navigating slippery roads, or pushing through moderate off-road terrain in your Silverado, Sierra, Ram or Express HD van, the YDGGM11.5-30-1 gives you the traction performance you need with the street manners you expect from a quality limited slip.\u003c\/p\u003e\n\n\u003ch4\u003eKey Features and Benefits\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e4320

The Grizzly Locker is a mechanical positive locker that provides 100 percent lock-up at all times, making it the better choice for extreme off-road, drag racing and rock crawling but noisier on dry pavement. The Dura Grip requires LSD additive and will eventually need clutch pack replacement, while the Grizzly Locker is mechanical with no clutch packs to wear.\u003c\/p\u003e\n\n\u003ch4\u003eDoes the YDGGM11.5-30-1 Dura Grip fit all gear ratios in the GM and Chrysler 11.5 inch differential?\u003c\/h4\u003e\n\u003cp\u003eYes. The YDGGM11.5-30-1 is designed to fit all available gear ratios in the GM and Chrysler AAM 11.5 inch rear differential with 30-spline axle shafts. There is no need to select a gear-ratio-specific version of this differential.\u003c\/p\u003e\n\n\u003ch4\u003eWhat gear oil and additive does Yukon recommend with the YDGGM11.5-30-1 Dura Grip?\u003c\/h4\u003e\n\u003cp\u003eYukon specifically recommends high-grade non-synthetic GL-5 gear oil and two bottles of Yukon LSD additive (part number OILADD) for the YDGGM11.5-30-1. The use of synthetic gear oil is not recommended and may result in aggressive or noisy clutch operation. Always add the friction modifier to ensure smooth engagement and long clutch pack life.\u003c\/p\u003e\n\n\u003ch4\u003eIs the YDGGM11.5-30-1 Dura Grip rebuildable if the clutch packs wear out?\u003c\/h4\u003e\n\u003cp\u003eYes. The YDGGM11.5-30-1 is a fully rebuildable limited slip differential. When the clutch packs eventually wear, you can replace them without replacing the entire carrier assembly, making long-term ownership cost significantly lower than replacing a non-rebuildable unit.\u003c\/p\u003e\n\n\u003ch4\u003eDoes the YDGGM11.5-30-1 Dura Grip fit my 2015 Chevrolet Silverado 2500 HD with the AAM 11.5 inch rear axle?\u003c\/h4\u003e\n\u003cp\u003eYes. The YDGGM11.5-30-1 is compatible with 2001-2019 Chevrolet Silverado 2500 HD models equipped with the GM AAM 11.5 inch rear differential and 30-spline axle shafts. Confirm your axle spline count before ordering if any previous axle shaft or differential work has been performed on the truck.\u003c\/p\u003e\n\n\u003ch4\u003eCan I install the YDGGM11.5-30-1 Dura Grip on my 2008 Dodge Ram 3500 Cummins diesel?\u003c\/h4\u003e\n\u003cp\u003eYes. The YDGGM11.5-30-1 fits 2003-2010 Dodge Ram 3500 models with the 11.5 inch AAM rear differential and 30-spline axle shafts. The AAM 11.5 inch axle was used across both GM and Chrysler heavy duty truck platforms, making the Dura Grip a direct-fit solution for Ram diesel applications within the fitment range.\u003c\/p\u003e\n\n\u003ch4\u003eWill I notice any difference in handling or noise after installing the YDGGM11.5-30-1 compared to a factory open differential?\u003c\/h4\u003e\n\u003cp\u003eThe YDGGM11.5-30-1 Dura Grip provides noticeably better traction on slippery surfaces and during hard acceleration compared to a factory open differential. Unlike a mechanical locker, the Dura Grip does not produce ratcheting or clunking sounds during normal street driving. There may be a slight increase in rear wheel resistance during very tight low-speed turns, which is normal for limited slip differentials.\u003c\/p\u003e\n\n\u003ch4\u003eHow often should I service the YDGGM11.5-30-1 Dura Grip limited slip differential?\u003c\/h4\u003e\n\u003cp\u003eYukon recommends following the vehicle manufacturer's differential service intervals for the 11.5 inch AAM axle, typically every 30,000 to 50,000 miles under normal use or more frequently under towing, off-road or high-performance driving conditions. Always use the correct non-synthetic GL-5 gear oil with LSD additive on each service to maintain smooth clutch operation and maximize clutch pack life.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n\u003cli\u003eDrain the rear differential gear oil completely before beginning disassembly.\u003c\/li\u003e\n\u003cli\u003eRemove the differential cover and allow all residual oil to drain, then clean all mating surfaces thoroughly.\u003c\/li\u003e\n\u003cli\u003eMark the bearing caps with a paint pen before removal to ensure correct reinstallation on the original sides.\u003c\/li\u003e\n\u003cli\u003eRemove the bearing cap bolts and both caps, then carefully lift the factory differential carrier out of the housing.\u003c\/li\u003e\n\u003cli\u003eTransfer the ring gear from the factory carrier to the YDGGM11.5-30-1 Dura Grip carrier using new ring gear bolts, torquing them in a cross pattern to the differential manufacturer specification.\u003c\/li\u003e\n\u003cli\u003eInstall the Dura Grip carrier assembly into the housing, seating the bearing races onto the bearing journals.
