SAS-XL: for custom bikes that are extra low and need extra lift

The SAS Air Suspension has no compressor to mount, no hoses to run, no fittings to fail & is completely plug and play! Absolutely the easiest install.

SAS-XL versions have an added 5/8" length to the cylinder housing - giving you about 2" more travel at the swing arm for a total of approx 6". Ideal for custom bikes that are extra low and need the extra lift to raise the bike to a ridable height.

Raise and lower your rear end at the touch of a button. Add air pressure to improve ride quality, during changing road conditions or while hauling added weight. Add extra air to compensate for your passenger and then release some for solo riding. You can also release all of the air and park your bike down on the ground. Adjustable air pressure makes for a smooth comfortable ride under any condition. No more bottoming out! 

This unit has more travel than a stock Harley Davidson frame, therefore use of this unit is unnecessary.

SAS-XL Custom Motorcycle Air Suspension



The Benefits of an SAS Air Shock:

  • Stay EPA Compliant on stock Harley Davidson’s by not having to move canisters to make room for an ugly compressor.
  • The SAS has an easy operation.  Simply add air to increase firmness and release air to soften up the ride. 
  • Machined 6061 billet aluminum housing that is hard anodized for longevity, and durable to protect all mechanical functions inside.
  • Pneumatic seals, and top quality O-rings are forever protected, and eliminate leaks.
  • Remote filtered air breather allows you to hide the air intake under your seat keeping the unit from ever pulling in contaminated air.
  • All Moving parts and bearings are permanently lubricated.
  • Adjustable air pressure from 0 to over 250 psi.



The SAS-XL Simplified air suspension offers 3-6" of swing arm travel. At approx. 150 psi the bike will be fully raised and the suspension will be resting on its piston bumpers at *maximum ride height*, after that your height will not change but you can continue to increase air pressure for improved riding during cornering or with a passenger.  The *maximum ride height* is adjustable during the installation.

Whether you enjoy your ride at stock height, or wish to ride the bike at a lower position. By simply increasing the mounting length from eye to eye of the shock you can lower the bikes *maximum ride height*. Lowering the bike reduces the swing arm travel, but with the convenience of an air shock you won't have to worry about bottoming out under any weight the bike may be carrying. With the SAS you can counter the weight with air pressure.

We recommend you consult an authorized dealer on how much you can lower your bike before safety becomes and issue. You can increase the ride height by shortening the eye to eye mounting length.


Specs, for mounting, and adjusting *maximum ride height*:

The SAS XL-99 uses a female male rod end with 2 jam nuts to adjust the mounting length. If a longer length is needed you can get a longer 1/2" 20 threaded rod.

The SAS XL has a minimum eye to eye length of 11 7/8" and can be lengthened with supplied hardware.  It can also be shortened with a male rod end.  Or lengthened even more with a longer threaded rod.  

Due to some frames bumpers you may not get the full 6" of travel, that also depends on the position you set the *maximum ride height* .  As a consequence of of custom applications, you may need to make adjustments specific to your application, but most custom frames are built to H/D measurements, as always - call us with questions, we are happy to help!

You do not want to tighten the rod ends down, there should be float.
Shoulder bolts should be used, any tension on the rod ends will cause the unit to bind up.
