Important questions you should ask any axle supplier when making an axle investment for your TJ or JK:
- Is your confidence in your axle's quality and performance assured because it is 100% manufactured and assembled in the United States? (Don't get fooled by others with Chinese parts)
- Has your axle been designed from the ground up exclusively with components that are designed to work together? (Some use components from other axles that are forced to work together)
- For the life of your vehicle will you be able to service your axles with off-the-shelf components like brakes, bearings, races, and seals?
- Can you be assured a "no-fault" warranty if you properly service and maintain your axles?
- Will your axles be made from 100% new parts and not with some parts that are recycled, refurbished or salvaged?
- With a looming rock approaching your investment, does your axle have well over 1-inch of additional ground clearance you need to keep from getting hung-up, stuck, or damaged?
