An incorrect depth causes premature wear, noise, and heat. Shims are the adjustment mechanism that allows you to move the pinion forward or rearward until the contact pattern lands in the proper zone. Using a quality shim kit with consistent machining means you can trust your measurements and get the contact pattern right the first time.\u003c\/p\u003e\n\n\u003ch4\u003eAbout Yukon Gear Differential Components\u003c\/h4\u003e\n\u003cp\u003eYukon Gear has built a reputation among professional builders and serious off-road enthusiasts by engineering drivetrain components to tight tolerances. Their shim kits, bearing kits, and install kits are designed to work together as a system, giving the installer everything needed for a complete, professional-quality rebuild.\u003c\/p\u003e\n\n\u003ch4\u003eInstallation Instructions\u003c\/h4\u003e\n\u003col\u003e\n  \u003cli\u003eRemove the differential cover and drain the axle fluid completely.\u003c\/li\u003e\n  \u003cli\u003eRemove the pinion yoke, pinion nut, and carefully press out the pinion gear.\u003c\/li\u003e\n  \u003cli\u003eRemove the existing pinion depth shim from behind the rear pinion bearing.\u003c\/li\u003e\n  \u003cli\u003eMeasure the existing shim thickness and compare it to the required depth specification for your ring and pinion set.\u003c\/li\u003e\n  \u003cli\u003eSelect the appropriate shim or combination of shims from the SK GM14T kit to achieve the target depth.\u003c\/li\u003e\n  \u003cli\u003ePress the rear pinion bearing onto the pinion with the selected shim in place.\u003c\/li\u003e\n  \u003cli\u003eReinstall the pinion assembly into the carrier and set pinion bearing preload using a crush sleeve or solid spacer per your ring and pinion kit instructions.\u003c\/li\u003e\n  \u003cli\u003eInstall the ring gear and set backlash per manufacturer specification.\u003c\/li\u003e\n  \u003cli\u003eVerify tooth contact pattern using gear marking compound before final assembly.\u003c\/li\u003e\n  \u003cli\u003eReinstall the differential cover with a fresh gasket or RTV sealant, fill to proper fluid level, and torque all fasteners to specification.\u003c\/li\u003e\n\u003c\/ol\u003e\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Pinion depth setup requires precision measuring tools including a dial indicator and depth micrometer.

This includes the C\/K 2500 and 3500, Silverado and Sierra 2500 HD and 3500 HD, Express and Savana vans, and the Suburban 2500.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eDo I need this kit for every ring and pinion install?\u003c\/strong\u003e\u003cbr\u003e\n    Yes, in most cases. The pinion depth must be set any time the pinion or its supporting bearings are removed. Using the correct shim thickness ensures proper gear tooth contact and prevents premature wear.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eHow many shims are included in the kit?\u003c\/strong\u003e\u003cbr\u003e\n    The kit includes multiple shims of varying thicknesses so you can select the correct combination to achieve your target pinion depth specification.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eCan I reuse the old pinion depth shim?\u003c\/strong\u003e\u003cbr\u003e\n    Reusing an old shim is not recommended if the bearing or pinion has been replaced. Manufacturing tolerances vary between parts, and the old shim may not place the new pinion at the correct depth. A new shim from this kit ensures accuracy.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eDo I need special tools to set pinion depth?\u003c\/strong\u003e\u003cbr\u003e\n    Yes. You will need a dial indicator, depth micrometer, and a pinion depth gauge or equivalent setup tools to accurately measure and set depth. Gear marking compound is also needed to verify the tooth contact pattern before finalizing the build.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eIs this the same kit used for a regear and an overhaul?\u003c\/strong\u003e\u003cbr\u003e\n    Yes. Whether you are changing gear ratios or simply replacing worn bearings, the process of setting pinion depth is the same and this shim kit covers both applications.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eDoes this kit include a crush sleeve or pinion bearing?\u003c\/strong\u003e\u003cbr\u003e\n    No. This kit provides the pinion depth shims only. Crush sleeves, pinion bearings, and other overhaul components are sold separately by Yukon Gear.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eWhat is the GM 10.5-inch 14 bolt axle rated for?\u003c\/strong\u003e\u003cbr\u003e\n    The GM 10.5-inch 14 bolt is one of the strongest factory axles ever produced for a half-ton or greater GM truck. It is rated for substantial towing and hauling loads and is a popular choice for lifted trucks and tow rigs because of its robust design and wide aftermarket support.\n  \u003c\/li\u003e\n  \u003cli\u003e\n    \u003cstrong\u003eCan this shim kit be used on the GM 9.5-inch 14 bolt axle?\u003c\/strong\u003e\u003cbr\u003e\n    No. This kit is specific to the GM 10.5-inch 14 bolt truck axle. The 9.5-inch axle uses different specifications and requires its own shim set.\n  \u003c\/li\u003e\n\u003c\/ol\u003e\n\n\u003ch4\u003eProposition 65 Warning\u003c\/h4\u003e\n\u003cp\u003e\u003cstrong\u003eWARNING:\u003c\/strong\u003e This product can expose you to chemicals including lead, which is known to the State of California to cause cancer and birth defects or other reproductive harm.
