Custom Manufactured Bilstein rear shocks.  Designed specifically for '66-70 Datsun roadster. 
 
"Nismo Koni" -medium damping curves.
 
Incredible quality. Fully rebuildable  -  you will never need to buy another set of shocks!
 
 
Direct Fit-no mods required.  
 
These are calibrated the same as the more expensive rear units, but do not have a nitrogen fill port, so they are less expensive.  Same great performance, lower cost!
