    I have an Ultra Wedge with Fox adjustables. I want to get as much ground clearance as possible.
    This means high pre-load right? And also harder ride. How will that effect the bite of the ski?
    As it is I would like a lot more response from my steering. I'm running factory skis with carbides.

    Jacking up front spring pre load will make less ski pressure there for less ski bite.

    Increasing spring preload on the front springs increases ski pressure.

    This quote is from a collection of many suspension tuning guidances I have acquired
    Increasing the spring preload too much may adversely affect the handling of the snowmobile and the performance of the rear suspension.

    To determine if your machine is using full travel, push the shock Jounce bumper down as far as it will go on the shock rod and test ride the machine.

    The preferred method for changing ski pressure under steady throttle conditions is to increase or decrease IFS spring preload.

    im sorry, i thought i read front track shock, one of them moments, but yes increasing front spring pre load will increase ski pressure.

    Just keep in mind that too much front shock pre load can cause your carbides to wear more rapidly and also can cause darting problems.

    I had my springs cranked up for the first ride of the year. Lucky, it was just a local, short ride. The steering was so heavy and darting all over the trail. I came home and and backed off the springs about an inch or preload and made it handle like it should. Much lighter steering, no darting (or minimal) and much better on the trail.

    Start with the pre-load low, and increase in small increments, only as necessary. 1/4-inch of additional pre-load can make a big difference.

    Increasing the pre-load on your torsion springs or decreasing the pre-load on your front track spring will also increase your ski pressure.
