Revolution Gear & Axle Jeep TJ/YJ/XJ Dana 30 w/27 Spline Chromoly Discovery Series Front Axle Kit

If you're pushing your Jeep TJ, YJ, or XJ hard off-road, especially with larger tires or lockers, upgrading your front axle shafts is a smart move. This Revolution Gear & Axle Discovery Series kit replaces the stock Dana 30 axle shafts with stronger chromoly units designed to handle more abuse. It's built to keep you moving when the trail gets tough.

This kit features axle shafts made from 4340 chromoly steel, a material known for its excellent strength and durability, making it a popular choice for heavy-duty drivetrain components.

Revolution Gear & Axle includes everything you need to swap out your stock shafts for these improved components, ensuring a direct replacement installation. This upgrade is a solid step towards building a more robust drivetrain for your Jeep.

When installing new axle shafts, it's a good time to inspect your U-joints and consider replacing them if they show any signs of wear. This kit is designed to be a direct fit for the Dana 30 axle found in many Jeep TJ, YJ, and XJ models, providing a straightforward upgrade path for off-road enthusiasts.
