    Any recommendations on which leaf to change for a supercharged raptor to reduce wheel hop? I've heard that you want to replace #5 for 10% higher spring rate but I wanted to see what you all thought of this.

    Icon engineer response

    "The higher rate configurations of the spring are intended for vehicles that are set up with constant additional load such as chase racks, dual spares, ect.

    With an unloaded truck going to a higher rate will also make the truck taller by about ½” per 10%rate change. This may make the vehicle taller than you want and the additional height may exacerbate the wheel hope tendency.

    The spring however is designed to reduce axle rap in two ways: by removing the stock block the leverage on the spring pack is reduced. And the pack incorporates an additional forward leaf on the top of the pack to reduce axle wrap. The leaf pack in its low rate as shipped will give a big improvement in axle wrap over the stock pack.

    Additionally you can experiment with the rebound settings of the rear bypass shock when on the street to further control the wheel hop. By adding rebound control (screwing knob in) to the rear shock you can slow the recoil of the spring and dampen the hop. Don’t over do this in the dirt however or the suspension will move to slow and pack up."

    I actually missed your other posted comment asking about that. Thank you for posting this information! I have the ICON rear shocks but they are matched with the national springs instead of the ICON progressive rate springs and the wheel hop with my Roush is minimal. I only get wheel hop on the street if I get on it going downhill at an angle at this point, but I haven't played with the shocks to see if I can improve that since I rarely get on it hard enough to spin the tires.

    Thanks for the info Chris...glad we could get an answer from Icon on this as I had heard all options recommended from the standard as is set-up, the 10% replace a leaf, and add a leaf 20% option. It sounds like leaving the Icon springs as is may be the best bet...troubling if no on else is running these springs but I'll let you know what I find

    Looks like @Rmeir is running this setup
