With AMSOIL Shock Therapy Suspension Fluid, viscosity
remains constant and aeration and foam are greatly reduced, significantly
limiting shock fade and inconsistent dampening. AMSOIL Shock Therapy
Suspension Fluid (STL & STM) is formulated for fade-free dampening
and smooth rebounds in many racing and recreational applications,
reducing rider fatigue and enabling the driver to ride longer
and harder while keeping focused on the terrain ahead.
Reduces Friction and Wear
Constant friction in a shock body decreases suspension
performance while causing scuffing and wear on the inner walls.
AMSOIL Shock Therapy Suspension Fluid contains friction modifiers
to reduce frictional energy loss and heat buildup. Anti-wear agents
protect against premature scuffing and wear, while maintaining
proper suspension absorption.
Temperature and Performance
AMSOIL Shock Therapy Suspension Fluid features
high pour and flash points, maintaining its ability to provide
superior protection in both high and low temperature extremes.
It is highly resistant to volatility, avoiding breakdown and resisting
the buildup of sludge and deposits.
Maintains Seal Pliability
AMSOIL Shock Therapy Suspension Fluid includes
seal conditioners, keeping seals soft and pliable and extending
their service life.

Recommendations
AMSOIL Shock Therapy Suspension Fluid is recommended
for front forks and shocks in snowmobiles, motocross and cruiser
motorcycles, ATV's and other racing and recreational use vehicles.
Two different formulations are available: The lightweight grade
(STL) is recommended, but not limited to, Showa, Kayaba, Bilstein,
RydeFX, Penske, WP forks, RACETECH (US1) and Custom Axis suspension
systems that demand quick rebounds under extreme hot and cold
weather applications, while the medium grade (STM) can be used
in Ohlin, FOX, RACETECH (US2), Koni, WP shocks and Harley-Davidson
forks that recommend type "E" or "B" fork
oils, as well as other applications that require more dampening
and slower rebounds. Refer to the owner's manual for individual
capacities, proper disassembly and further recommendations.
Owner's manuals may refer to weights when recommending suspension
oil. These weight numbers are arbitrary because no industry
standard exists for classifying suspension oil. The numbers
can range from 2.5 to 30, depending on the manufacturer. AMSOIL
STL correlates closely to a 5 weight, while AMSOIL STM is close
to a 10 weight.
Compatibility
AMSOIL STL and STM can be mixed together based
on individual requirements and applications, and they are compatible
with most other suspension fluids.
Product Availability
AMSOIL Shock Therapy Suspension Fluids are
available in quarts and 5-gallon pails.
