Product Description

The Energy Suspension 11.4101R kit replaces the rear differential carrier bushings on 1990-2005 Mazda Miata applications with performance polyurethane components. Compared with worn factory rubber bushings, these bushings are designed to better control differential movement, helping the driveline feel tighter during launches, gear changes, and hard cornering.

This kit fits rear-wheel-drive Mazda Miata models across the NA and NB generations, including 1990-1997 and 1999-2005 applications. Energy Suspension identifies this as a rear-position direct-fit kit made from red polyurethane and supplied with zinc hardware. Because this part is a differential carrier bushing kit, fitment should remain limited to the confirmed Miata applications listed above and should not be assigned to other Mazda platforms without separate verification.

No lift or drop height applies to this product because it is a driveline bushing kit rather than a suspension height-changing component. Fitment confirmed through 2005. 2006-2025 coverage unconfirmed at time of listing.
