Shock Conundrum
 
I have a 2" lift and am in need of new shocks.

So Rubicon Express makes a Monotube Shock kit that is designed to fit 2" - 3.5" lifts. Unfortunately, everyone is out of this kit (even RE themselves). But everything I read talks about ordering/buying/installing the correct length shock for your jeep.

Here's my logic: If this reputable company is willing to sell/recommend a kit that spans 1.5" of fudge room, what's the harm of buying a 3" shock from Bilstein or Rancho?

I understand that there are bump stop and damage issues associated with incorrect shock lengths, but I'm still overall very confused.

Thoughts?

Too short a shock without the right bumpstops will kill the shock in short order. Too long a stroke in the shock will also cause issues. The best way to get the right one is to measure the distances involved and get a shock to fit. On a side note I have a pair of the RE monos for the back that rode real nice. I just got a matched set of Bilseins given to me or else they would still be in there. Real nice ride from both.

Try this.
Size really does matter here. It is very important that you use a shock that is the right length and has enough travel in both compression and rebound to dampen the axle it is connected to. In the easiest of all situations, the shock is mounted straight up and down. The measurement is fairly easy. Measure the distance from the suspension bump stop to surface that it makes contact with, and add a " for compression of the bump stop. This measurement is your compression travel. Now measure from your upper shock mounting point, to the lower mounting point. For explanation purposes, lets say that the distance from the bump stop to the contact surface is 5.5" and we add a " we now have 6". Lets also say that the distance from the top mounting point of the shock to the lower mounting point is 14". Given these two measurements it is easy to see that you have a difference of 8". This 8" measurement is the length of the shock body you would need to control travel, measured from the mounting eye to the top of the shock body, and not limit suspension travel. In this situation you would actually have approximately 8" of rebound or droop travel in the shock and 6" of compression travel.

Or any reputable 4x4 that has any idea of what they are doing will be able to suggest multiple shocks for you to choose from of the proper length just by telling them how high your lift is.
