Complete Front and Rear Gear Package with Quality Components

If you want to get back some pep, acceleration and power band after adding bigger tires onto your aggressive F250 or F350 build, then adding a set of 4.88 gears to your Super Duty is the way to go. Make sure to get everything you need for your F250 or F350's 4.88 gear swap with this awesome Complete Front and Rear 4.88 Gear Package. This near-total driveline overhaul comes with a set of Yukon 4.88 front ring-and-pinion gears and a set of Yukon 4.88 rear-and-pinion gears, as well as Yukon Master Install Kits for both the front and rear ends of your truck so that you replace all the critical wearable components of your differentials while getting the high-quality gears your Super Duty needs to operate at its very best. Yukon's ring-and-pinion gears are some of the strongest and toughest in the business, and will let your aggressive F250 or F350 build tackle and terrain or challenge that you have in mind. 4.88 gears make for an excellent upgrade over factory gearing and can help add some sprightliness back to your F250 or F350 after you've jumped up to larger tires.

High-Quality Ring-and-Pinion Gears with Precise Machining and Lapping

Yukon's front and rear 4.88 gears are made using some of the strongest gear steel on the market and are precisely machined for a perfect fit and quiet operation. Each ring-and-pinion gear set is manufactured out of forged, triple-alloy 8620 gear steel that's incredibly strong and can handle both high levels of horsepower and torque, as well as intense off-road applications without letting you or your Super Duty down. Both the ring and pinion gears are precisely machined by Yukon to ensure perfect fitment in your truck. All of the gear teeth go through an ultra-precise, computer-controlled lapping process that ensures a smooth engagement between the ring and pinion gears so that you get reduced noise and flawless operation in practically any condition or application. Both the front Dana 60 and rear 10.5" gear kits drop right into place of your F250 or F350's stock gearing with the help of Yukon's install kits.

Complete Install Kits with Shims, Bearings, Races, and Other Hardware

Yukon's front and rear Master Install Kits come with everything you need to get your gears installed and running perfectly. Each Master Install Kit comes with both carrier and pinion shims for getting the perfect gear mesh. These kits also include high-quality Timken bearings and races, seals, pinion nuts, marking compounds, and everything else you need for your front and rear gear installs. Yukon's Master Install Kits let you replace the tired-out differential components with new and high-quality components that ensure reliable and smooth gear operation for years to come.
