Steel shims help keep driveline angles correct to help with vibration, prevent U-joint binding, and help fight spring wrap if your pinion is sticking up a bit too high. We carry different sized shims for different needs.
These are steel shims, NOT aluminum! Aluminum shims can cost a couple bucks less, but will crack apart and fail over time. Is your life worth a few bucks? Steel shims will last forever and are VERY safe.
Also great for correcting castor angles on front CJ & YJ axles. Improper castor is caused by longer shackles and can cause sloppy handling at highway speeds. Shims are a critical component in proper front end alignment for any leaf sprung vehicle that has been lifted.
Picture shows a spring over setup, but our shims work for spring over or springs underneath the axles.
2" wide shims would be used on CJ's 1976 and newer in the front.
2.5" wide shims would be 1976+ rear, and all YJ Wranglers.
Temporarily out of production
*Please note: 3* and 5* shims are typically stocked. Other sizes may required a couple extra weeks for the custom cutting.
