Öhlins Professional Motorsport Products TTX 25 MkII FSAE 267/90 mm

Öhlins understands the importance of relationships from beginning to end, from racers in training to experienced veterans. It’s for this reason that we developed the TTX 25 MkII FSAE - a shock absorber specifically for Formula SAE/Formula student racing.


The TTX 25 MkII FSAE uses our well-proven twin tube technology, in a small package. The 4-way externally adjustable damper is completely serviceable and offers the possibility for setting changes. With a wide range of springs together with dynamometer plots, CAD models, and other technical information, the TTX25 FSAE provides the perfect package for Formula Student racing teams.
