F-O-A 3.5 Inch ID Piggyback Bypass Shock, 14 Inch Travel


Our 3.5″ 5 tube bypasses are FINALLY available to the public! These have been used exclusively on sponsored racecars until now. The test and tune phase is over and they are ready to ROCK! 3.5″ body ensure cool running in even the harshest conditions. We mount a piggyback 3″ reservoir for a clean and small package. 5 tubes worth of adjustment (3 compression tubes and 2 rebound) make sure you never run out of tuning ability.

These shocks are proven on some of the fastest Ultra 4 and Class 1 racers out there. If you are serious about going fast…this is the shock for you. When placing your order, let us know the planned use in the “special instructions” area and we will valve them accordingly.

These shocks will be a ‘build to order’ basis only. That means it will typically take 3-4 weeks to build them, though it may be longer in some cases. Please plan accordingly with your build, as we can not guaranty any ship times on them. If you need them within a specific timeframe, you need to contact us to verify we can fill the order in time.
