i used a skf seal block on a 010 two stroke one or look to see if racetech do a block did look at fitting a different seal to the std block showa kyb wp use the same seal on there 18 mm shock good luck
The sachs seals are pretty resilient.. Is yours actually leaking when under full pressure? How does the shaft look?
Getting a seal or complete seal head for a Sachs can be a pain in the ringbit... Most tuners will mill the stock seal head to take a KYB/Showa seal, otherwise SKF do a complete seal head. You just need to be sure on which one you need. Sachs use 16 and 18mm shafts.. some use top out spring assemblies, while others have a bump stop on the seal head. Few different height seal heads getting around too!
