Tuff Country 3° Axle Shims – 2003–2023 Ram 3500 / 2003–2013 Ram 2500 4WD (3" Wide, 1/2" Center Pins) (90018)

Correct driveline angles and eliminate vibration on your lifted Ram with the Tuff Country 3 Degree Axle Shims. Designed for trucks equipped with Tuff Country lift kits, these shims help restore proper pinion angle after suspension modifications, improving driveline performance and reducing stress on components.

These axle shims are installed between the leaf spring and axle to adjust the rear differential angle. This is critical when lift kits change suspension geometry, which can cause vibration, premature wear, or driveline issues if left uncorrected. Built for durability and precision fitment, these shims are ideal for both daily driving and heavy-duty applications.

Sold as a pair, they provide a direct solution for correcting driveline alignment on lifted vehicles.
