Jeep Wrangler Coil Bucket (Pair)
Ideally you would use these for a rust belt replacement or when swapping in a new axle and want to use the stock or lift coils in the same diameter.
The surface of the pad is 6 5/8" diameter and the OD of the locator is 2 1/2" so these are perfect for the TJ but can be used with many different springs also.
They are sold in pairs and should be welded on by a competent person with the correct equipment.
