For those who have done some serious high-speed off-roading, and/or those who have performed suspension measurements - I'm curious if you've a) found the limits of our Expeditions' suspension travel to get in the way of your off-road travels and/or b) have experienced notably better down-travel with aftermarket Upper Control Arms.
According to this old Ford Press Release, Expedition suspensions starting from 2003 (2nd gen) were designed with 9.4 inches of vertical suspension travel/range, which is impressive for a stock suspension. According to this article on AccuTune's website about high-speed off-road travel:
- Does the immense weight of our vehicles negate any benefits that could be had with such long travel suspension?
- Are benefits to be realized by aftermarket UCAs - i.e. more down-travel - limited because our stock suspensions start with a pretty good amount of travel?
- Do any of you use hydraulic bumpstops, jounce-springs (Timbrens, Sumo) or something similar to control bottoming?
- Those who have extended travel shocks - have you had to use limiting straps in order to avoid damage to suspension components due to excessive down-travel? I've found that the Bilstein 6112's for the F-150 that I have installed in the front allow for an impressive amount of droop, though I'm not sure if it's out of the design range of the stock UCA's.
Thoughts?

- 4” of up travel, and 4” of down travel are the minimum recommended for any type of off-roading
- 6” of up travel is a good minimum goal if you want to go fast
