Lift height vs shock ability

[Artsifrtsi]

It's slow because you don't have to pull the coils and shocks to get your fully compressed measurement.

You do not need the springs and shocks out of the way. Measure between shock mounts at ride height. Measure travel before bumpstop hits. Subtract for bumpstop compression. Do math.

Fully extended you can measure just for fun. But you'll be buying the shock that fits the fully compressed measurement unless you plan to add some bumpstop.

Shock travel, not length, is the most important measurement that you need to order shocks that will work correctly... Yes, the shock needs to physically fit too, but travel is the most important.

I cannot see how you are able to measure to order the correct shock using the bump-stop measurement. The only time that measuring Bump-stop is a thing, is determining tire and wheel size/offsets. (cycle axles without springs, and with shocks/wheels/tires to determine how much bump-stop you need to prevent rubbing)

Travel is not the most important. Most important is the shock fits.

I have a 12" travel shock. Will it fit your Jeep? You have no idea without knowing the compressed measurement.

You are not thinking about the "bumpstop measurement" correctly. What is being measured is how much uptravel there is before the bumpstop stops uptravel. If the shock mounts are 25" apart and you have 7" of up before the bumptop stops uptravel, you know the shock mounts will be 18" apart when it's sitting on the bumpstop.

Both methods are good, getting the true measurements are better though, as different shock bodies could have different measurements (a 2 inch travel shock could be 6 inches or 12 inches long, depending on how it's built)

It is still best to build around utilizing the max potential travel of the suspension... I'd rather limit strap and bump-stop than allow the shocks to bottom out either on compression or extension

I would reach out to Falcon for further explanation with this chart, but in our testing and based on customer feedback the 2-3" shocks work best with the 2.5" kit. In general, longer travel shocks on the Gladiator tend to be a bit too long even for the 3.5" lift, and even Falcon recommends running a set of limiting straps or spring retainers with the longer version, so I would personally stick with the shorter version for the 2.5" lift.

This is the Falcon shock set you are recommending, correct?

For a non-diesel 2.5" lift that would be the correct part number!

So, I need adjustable front bumps rather than Sumo Springs to plan for the future then...

Hey Chris!

The heights of our kits are based on the amount of lift gained in the rear as this is the taller end of the vehicle, and all of our kits are about .5" taller than advertised. We also remove about 1" out of the 2" of factory rake, which means you're gaining an additional inch up front. For example, our 2.5" kits on the JT would work out to about 3" of lift in the rear and 4" of lift in the front.

Fox and Falcon shock packages listed as 2-3" of lift work perfectly with this setup as most shock manufacturers take into consideration that the front end tends to get a little extra lift.

@Clayton Off Road this is good info.

But is the 2.5" of nominal lift based on a stock Sport, Rubicon, or Mojave?

And when you measure the rake, is it from Sport fenders, Rubicon fenders (1.5" higher than Sport), body (rock rails), or lower control arm bolts on frame?

Hey Mike, all lifts are designed on Rubicon models, so expect just slightly more lift gained on Sport models. We always measure the rake from the ground to the bottom of the rock rails!
