If you're looking to take your Jeep's performance up a notch, the Yukon Stage 4 kit is a solid way to go. This isn't just a bunch of parts thrown together; it's a thoughtfully designed package that really gets what off-roading is all about. You get front and rear ring and pinion sets, which are crucial for improving traction and handling, especially if you’re thinking about tackling tougher trails. The 4.88 gear ratio is a game-changer, giving you that extra oomph when you need it, whether you're climbing rocks or cruising through mud.
Now, let’s talk about the nitty-gritty. This kit fits the front Dana 44/M210 and rear Dana 44/M220 differentials, and it’s designed with the rear in mind for those running a posi setup. The 28 spline pinion gears are tough enough to handle the stress you’ll put on them, while the Master Overhaul kits for both front and rear make installation a lot smoother than you might expect. You’ll appreciate the nodular iron Yukon Hardcore Diff Covers—they’re built to take a beating and keep your gears protected. Plus, the 4340 chromoly front and rear axles add that extra layer of durability, which is something you definitely want when you’re out there pushing your Jeep to its limits.
This kit is specifically made to fit the Jeep Gladiator from 2020 to 2023 and the Jeep Wrangler from 2018 to 2022, so you know it’s tailor-made for your ride. If you’re serious about upgrading your gear, this Yukon Stage 4 kit is worth considering. It’s not just about the specs; it’s about giving you the confidence to tackle whatever the road—or trail—throws at you.
