Frequently Asked Questions
Why are your shocks less expensive then your competitors?
We use a Patent Pending High Pressure Die Casting process in manufacturing a number of components in our shocks. This process of die casting the aluminum components cost much less then using wrought material, we pass these savings on to the customer. With this new process these shocks are much stronger then previously seen in cast aluminum parts. With this Patent Pending process we can deliver quality and price not seen before.
What type of valving do I want in my shock?
Most vehicles need very little rebound and every vehicle needs different compression valving, FOA has 6 general valving's for compression- Zero, Extra Light, Light, Light/Med., Med., and Firm. For rebound we have Medium, Light and Zero. (Zero is generally spec’d when using a coilover as a “coil carrier”, and using another shock to provide your damping.) When ordering you can specify the valving you want or give us the vehicle weight, the amount of shocks per wheel and type of terrain and speed you are driving and we can valve them for you. Every FOA shock can be re-valved to meet your desires. No special tools are required.
Do you make an air shock?
No, our shocks are all hydraulic based. Your vehicle will still need springs of some sort.
Do you make a shock to fit the Rhino/Polaris/Arctic Cat UTV's?
Soon, our new 2.0 series will work well on UTV's. We have a number of pieces coming for them.
Emulsion verses Reservoir style shocks, which is better?
Reservoir shocks are generally thought to be better, with the Nitrogen gas separated from the oil, they can't mix and this creates more uniform dampening characteristics. The gas is necessary in all shocks to displace the space that the shaft takes up as it moves into the shock. The moving of the shaft into the cylinder also cause's an air spring effect on your shock. This air spring effect is more noticeable on an Emulsion shock verses a reservoir style. This difference between Emulsion and Reservoir shocks in most street applications is not significant. For off-road use, if you have the room to mount the reservoir, we highly recommend it.
What if I don't have room for the remote reservoir shocks on my vehicle?
Remember reservoir shocks are not mandatory on all applications. Both reservoir and emulsion mix use pressurized Nitrogen gas. We can also make extra long reservoir hoses so they can be mounted some distance away from your shocks.
Are these shocks OK for racing applications?
While our focus is recreational vehicles, we have a number of people using our shocks for racing. We suggest that if you plan on racing with these shocks that you upgrade to our “High Temp” option. You will get the Viton seals and an improved piston wear band to deal with the higher temps generated by racing.
What kind of seals are used?
Our seals are made of Buna Nitride, these seals will handle temperatures up to 250 degrees. We offer a Viton seal upgrade that will allow shock temps up to 400 degrees.
Will these Shocks fit my vehicle?
FOA Shock absorbers take a 1/2 inch bolt to attach to your vehicle at each end. They will bolt directly to many applications and on others they will need adapters. Your mechanic can install them usually with little additional expense. You can check our sizing and compare to what you may need. We do not guarantee fitment, you/your mechanic will need to check clearance and sizing before ordering.
Do you make custom shocks?
Yes, we make custom length shocks. They can take up to 6 weeks to produce in special lengths. Email us for more info and pricing.
What direction do I mount your shocks?
These shocks should always be mounted with the shaft downward. This keeps the seal flooded at all times.
How about springs for my vehicles suspension?
Next to shocks, springs are the most important item in vehicle ride control. We offer a full line of Eibach springs, and can assist with proper rate selection. Be sure to check out our Spring Rate Calculator to see what info is needed.
Where are your shocks made?
Everything is made in the USA and assembled in the Las Vegas area.
