If your really want to be technical about it, any change in ride height requires an alight but, there is a point you have to be realistic.

On almost any independent suspension set up your camber, caster, and toe change as the suspension cycles throughout its travel. Some of it is intentional, so of it is accidental or a consequence of some other desired geometry.

CAMBER:

Most vehicles lose camber or the camber goes more negative as the suspension compresses, (and vice versa) which is a feature not a bug. The theory is that when you take a turn and the outside of your suspension compresses, the decrease in camber fights tire rollover and retains a better contact patch throughout the bend.

CASTER

Most manufacturers build in anti dive geometry into their IFS designs which is a value that basically dictates how little or how much of the braking forces are transferred to the suspension. The greater the anti dive value the less of those braking forces make it to the suspension, and therefore the less brake dive you have. Thus the name.

This is a handy little trick for minimizing brake dive without making the front shocks and springs stiffer, however this is typically achieved by setting the upright/spindle/knuckle at a slight angle (top tilted back slightly towards the rear of the vehicle). The bug that comes with this feature is that means caster decreases as the suspension extends, and increases as it compresses.

TOE

Although not always intentional EVERY factory truck or SUVs bump steers a little bit, typically with the tires toeing out on compression and toeing in on compression. Some more than others, but bump steers is always present.

So What Does That Mean For You?

As you change ride height those geometric tendencies mean your alignment changes. As you go taller you gain camber, lose caster, and your tires typically toe in. And vice versa However on modern vehicles the change is not all that extreme.

If you are doing a different amount of adjustment from left to right, you’re going to need an alignment to keep from driving crooked, but if you do a 1/2” of change or less on both sides, chances are another alignment is a waste of time.

A lot of our customers get scared by the “black art” that is adjusting preload, but it’s a lot simpler than you might think. In fact our video on the topic just dropped, so if you have a set of coilovers you’ve been dreading adjusting, you definitely will want to check it out.

I can’t recommend this shock n spring package enough!!! Not just for the excellent 4x4 experience, but for the daily steer drivability! This is how Toyota should have set them up to began with! Smoother and more compliant in everyday situations. And off road is 10X better. Period. - Christian Y

Your coilovers or ride height adjustable struts probably have too much preload of:

1. It feels super “thumpy” over small bumps and cracks on the road as if your tires are slapping the pavement over ever minor impact.

2. You have next to no articulation on the trail even with your sway bars removed. If your coilovers or struts have more travel than stock, but your are lifting a tire more often than stock, it’s time to back off that preload and ride height to recover some down travel.

3. Topping out is probably the most common complaint we get from any aftermarket suspension system and the culprit id the set up and not necessarily the parts themselves. If your suspension crashes every time it rebounds or you feel like you are getting sucked into every hole or dip, you need some more down travel and that means less preload.

But if you want some tips and tricks on setting your preload, make sure to head over to our YT channel tomorrow at 3PM PST because we are dropping a quick tutorial on how to make those adjustments.
