While we recommend using heavy duty differential covers to pair up with our JL/JT/Bronco differential skids for the best combination of strength and longevity, it is possible to get by with factory covers for the installation of our differential skids with the use of these spacers. This part is the shim/spacer component required. Differential skid, differential cover, and hardware are sold separately and not included.
Spacers now come zinc plated to prevent corrosion.
