See what dirt bike riders are saying about AMSOIL Shock Therapy 10W.
"Switched to Shock Therapy 10W in my Showa forks. Night and day difference. Forks feel plush off the top and consistent through the stroke. No more fade after an hour of racing."
"Run enduro and my suspension takes a beating. This fluid stays consistent even when forks get hot. No foaming, no fade. Best fork oil I've used."
"Suspension tech recommended Shock Therapy. My KX450F forks finally feel like they should. Smooth, controlled, predictable. Worth every penny."
Common questions about AMSOIL Shock Therapy Suspension Fluid.
5W is lighter viscosity for softer damping. 10W is medium viscosity for standard damping. Follow your manufacturer's recommendation or suspension tuner's advice.
For racing, change every 20-30 hours. For trail riding, every 40-50 hours or annually. Change sooner if you notice degraded performance.
Yes, riders often mix 5W and 10W to achieve custom viscosity. Mix equal amounts for 7.5W weight. Measure carefully for consistent results.
No, Shock Therapy contains seal conditioners that protect and prolong seal life. It's safe for all fork seal types.
Most dirt bikes need 300-500ml per fork leg. Check your owner's manual for exact capacity. One quart bottle typically does both forks.
