Miata driveshafts aren't designed to be rebuildable. Over time, the universal joints will develop a flat spot that can eventually cause vibration problems. Some driveshaft shops claim to be able to replace these joints, with varying levels of success.
This is a brand new driveshaft with universal joints that are designed to be easily replaced (part #7260, usually available locally) even at home. Steel construction, made to the same dimensions as stock. Since Miatas don't break driveshafts, we didn't feel the need to go with a more expensive solution. Dynamically balanced for smooth running.
Fits 1994-05 manual transmission and 1994-97 automatic cars. Can also be used as part of a Torsen retrofit on a 1990-93 model.
Includes free ground shipping inside the US.
