Important Notes:
- These fully built axles are bare and designed for leaf spring applications only! No other bracketry should be welded onto assembled axles. If you are interested in purchasing this kit for 3-link or 4-link applications, we can send all components for your assembly. Please contact our Sales staff for details.
- In order to achieve full ground clearance, you will need to grind the bottom of the differential housing flange flush with the axle housing!

Ring and Pinion Break-In Procedure:
New 3rd members require a break-in period to prevent damage from overheating. Any overloading or over-heating during this period can cause the gear oil to break down resulting in ring and pinion failure.
- After installation, drive lightly for 20-30 minutes and then allow the differential to cool for at least two hours
- Avoid heavy throttle use during the first 500 miles
- Do not tow a trailer during the first 500 miles
- Change oil after 500 miles to remove any particles suspended in the oil
This may seem unnecessary but it is very easy to damage the differential by loading it before the gear set is completely run in. New ring and pinion gears create excess heat when they are new. This excess heat can damage the heat treatment of the gears.
