Fox 1.5 Zero QS3 Setup Guide

Fox 1.5 Zero QS3 Setup
The team at IceAge Performance strives to provide the highest level of service and support for all of our products. This section is dedicated to helping understanding the functions of the Fox 1.5 Zero QS3 shock package as well as setup recommendations for your weight and riding style.

Before adjusting and making changes to your shock we need to understand the components and what the adjustments affect in ride performance. The better the understanding of the functions the easier it is to make adjustments to meet your needs. Also please note the factory settings listed below so you can return to 'home base' if you find your setup has gotten off and you want to start over. All shocks work together as a system so adjustments to one shock will affect how the whole vehicle handles.

1.5 Zero QS3 Coil Spring Adjustments

We recommend at least .25" of preload on any coil spring to ensure the spring and retaining collar are firmly seated. When making preload adjustments we recommend making small incremental changes while out riding to your preload. Keeping adjustments smaller (under .25" at a time) should be done to help feel changes and how they are affective the vehicle. Rapid large changes often result in confusing and misleading affects on setup. Spring adjustments are used to set suspension 'sag' and initial ride height not to control bottoming ( see QS3 adjustment).



Ski shock preload adjustments should be used to achieve the following results. Increased preload will create a more 'planted' and stable front end in low speed maneuvers. Additional .25 - 1" of additional preload may be beneficial for larger riders(225+) to help maintain vehicle ride height. Decreased preload on the ski shocks will result in a sled that is softer and more compliant over small terrain changes and bumps. It can also result in a front end that can 'push' slight in corners with reduced ski pressure.

Skid shock preload adjustments can be used to achieve the following results. The front skid shock greatly controls ski pressure and weight transfer. Additonal front track shock preload will result in less ski pressure and more rapid weight transfer front to back when on and off the gas. The only side affect is this firmer shock is less compliant and will be more prone to trenching. Reduced FTS preload will result in more ski pressure and a sled with a more 'planted' feel capable of climbing on top of the snow better. The rear track shock adjustment greatly affects how the sled controls weight transfer. Increased RTS preload will create more ski pressure and help 'tame down' the sleds desire to wheelie.

For rider weight adjustments you should make a small increase to all shocks and not rely on 1 or 2 to do the 'heavy lifting' as this can upset the overall vehicle balance. As mentioned above, make small incremental changes until the desired results are achieved.

Fox Float 3 Evol QS3R Setup Guide

The team at IceAge Performance strives to provide the highest level of service and support for all of our products. This section is dedicated to helping understanding the functions of the Fox Float 3 Evol QS3R shock package as well as setup recommendations for your weight and riding style.

FOX Float 3 EVOL QS3R Pressure Ranges

Soft: 45psi MAIN & 150psi EVOL

Stiff: 90psi MAIN & 250psi EVOL

Float 3 Evol QS3R Adjustments

The FOX Floats come set with pressures of approximately 90 psi in the MAIN chamber and 100 psi in the EVOL chamber. These pressures may vary so its beneficial to check both chamber pressures beforehand to ensure consistency. Prior to the adjusting the pressures in your FLOAT 3 shocks it's important to note that you must set the EVOL chamber before setting the MAIN chamber. The uniqueness of the FOX FLOATS compared to the alternative Coils is they provide supreme bottoming out resistance through the progressive dampening technology and have a multitude of "spring rates" thanks to using air in lieu of a coil. Collectively this provides the consumer with a shock that can be tailored to the specific riding style and conditions to achieve full benefit of the air suspension.

The range of shock pressures can be adjusted from 45 psi in the MAIN chamber & 150 psi in the EVOL to a stiffer calibration of 90 psi in the MAIN chamber & 250 psi in the EVOL. Between these ranges is personal preference according to riding style and conditions.

For the FOX FLOAT 3 EVOL QS3R we recommend setting the shocks to a middleground setting of 65 psi in the MAIN chamber and 200 psi in the EVOL chamber. This will provide the rider with a baseline of whether to increase or decrease the pressures accordingly. Thereafter, changing the shock pressures in increments of 10 psi for both chambers. For larger riders weighing more than 225+ (with gear) or for those who are jumping more frequently, more air pressure may be necessary.

Skid shock pressures can be used to achieve the following results. The front skid shock greatly controls ski pressure and weight transfer. Additional front track shock pressure will result in less ski pressure and more rapid weight transfer front to back when on and off the gas. The only side affect is this firmer shock is less compliant and will be more prone to trenching. Reduced FTS preload will result in more ski pressure and a sled with a more 'planted' feel capable of climbing on top of the snow better. The rear track shock adjustment greatly affects how the sled controls weight transfer. Increased RTS preload will create more ski pressure and help 'tame down' the sleds desire to wheelie.
