* 300ZXT 4 bolt outerflange CV shafts (not the 6 bolt type) require the end cap removed, and inner CV race reversed, this effectively shortens each CV shaft 3/8" and results in correct rear geometry for your Z. This modification can be done with typical tools and we can supply guiding pictures to help (easily done in 1/2 hour). They work with stock rear control arms, if you've shortened yours or any similar effect be sure to check for adequate travel without binding in compression.

NOTE: 280Z stub axles and companion flanges as sets can be installed into 240Z's, the bearings are identical. Inquire if you need a bearing kit, we have them in stock.
