See what dirt bike riders are saying about AMSOIL Shock Therapy 5W.
"My forks were way too stiff on stock 10W. Dropped to Shock Therapy 5W and it's like a different bike. So much more compliant on chop. Perfect for lighter riders."
"Run 5W in the left leg, 10W in the right to balance my suspension. Shock Therapy mixes perfectly and stays consistent. Great product for fine-tuning."
"Older rider with bad knees. 5W weight makes my KX450F way more comfortable on rough trails. Forks soak up bumps instead of beating me up."
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.
