The Dana 30 axle under XJs, TJs, and ZJs is considered a lightweight axle, but it is surprisingly strong and can handle a tire and wheel package that is significantly larger than stock as long as the driver goes easy on the skinny pedal. However, larger tires, lower gears, and hardcore trails can stress the axle housing to its limit.
• Constructed of 1/4" thick steel
