Axle Upgrade Kits

Factory-installed Jeep axles can get the job done when you're hauling cargo or making an everyday drive, but off-roading demands more than just the factory standard. Rough terrain, steep inclines and sharp turns test your rig's axles more than anything else. When you hit the trail and feel that vibration beneath your feet, you wonder: is it nothing, or is my axle hitting its limit? Stop wondering and push the limits further with an upgrade from 4WheelParts.com. A Dana 30 upgrade kit will improve handling and cover the factory axle's weak points so you can take on the trail with confidence.

Tough Ride, Tougher Axles
Whether made by aftermarket suppliers such as G2 Axle and Gear and Alloy USA or by a Jeep OEM, these Dana 30 axle upgrades boast strength and toughness beyond the stock parts. High-grade steel features in every part - from hardy carbon steel to exceptionally tough Dana 30 chromoly axle shafts - and precise direct-fit engineering ensure excellent off-road performance. Our inventory carries replacement components for all axle types from CV-style and C-clip to bolt-in; the online catalog lets you narrow the search by your rig's year, make and model, while our panel of experts can advise you on the finer details.

Have you noticed leaks around the seal of your axle housing? Maybe you have recently upgraded to bigger tires and found that the extra strain is wearing your axles out quickly. No matter what the reason is, though, a Jeep Wrangler axle upgrade resolves the issue and provides your vehicle with the durability and power you crave. When it comes to an axle upgrade, a mechanic can certainly do the job, but dedicated jeepers like yourself are likely more drawn to the DIY route. In this case, getting the right parts is imperative to making sure you get the results you want out of your axle upgrade.

Signs That You Need New Axles ASAP
Axles, like any other part of a car, are liable to break. This is especially true for vehicles that are subjected to rough and tumble endeavors such as off-roading. For your front axle, the stress of such activities may eventually lead to bending on the ends. This is also where forgings can be vulnerable. They, too, can begin to bow upwards and compromise the alignment of your car. In extreme cases, axles or axles housings can crack completely due to excessive weight or impact. If you notice leaking or indication that any of these issues is occurring, you need to look into replacing your Jeep differential or axles sooner rather than later.

Finding the Right Upgrade Kit
Luckily, there are kits that make the process simple. You can get everything you need to do a full Jeep axle upgrade with an all-in-one kit. There are plenty to choose from, though, so you should consider which one is best for your Jeep's specific needs. A Dana 30 upgrade kit includes studs, bearings and axles and all additional gear needed to upgrade from your factory axles. The staff at 4 Wheel Parts is dedicated to helping you find the all the tools and parts you need to upgrade your Jeep. Whether you need to replace broken axles or invest in heavy-duty aftermarket replacements for more durable fun, we're here to supply all the necessary equipment.
