I have a brand new set of 4 Mopar U-bolts for the rear suspension on the 2500 4x4. These are #52038486 and fit trucks WITHOUT towing or camper packages and should fit all 2nd gen 2500's. They are 3" wide x 13" long and are 9/16 rod with 14mm x 2.0 threads. Please measure your bolts first.
$60 shipped to the lower 48. Thanks for looking.
