Custom Axle Buyer' S Guide

If You're In The Market For A Complete Axle Upgrade but don't feel like rummaging through junkyards or the classifieds, then take a look at some of the industry's leaders in aftermarket axles. From the toyota 8-inch to 5-ton rockwells, you're bound to find one of these companies itching to build you your dream axle. Many of them use advanced techniques and machinery to create hybrid axles to fit any wheeler's budget or build plans. Want a stronger axle, but feel the need to keep things a little more on the stock side? no problem. Many of the aftermarket builders design the axles to allow you to maintain factory ABs, stability control, and suspension points so you can keep things the way the factory intended. if you are more of a backyard builder, then a bare housing might be more your speed. Either way you spin it, by the time you get one of these aftermarket beauties delivered to your doorstep, you'll be looking for a place to mount it on the wall, not under your rig. yeah, they look that good.
