How to choose the length:

Actual lift height:
It is very important that you do not use the manufacturers advertised lift height for any calculations. Always use a hub to fender measurement with the vehicle loaded the way it is typically used. If you usually carry tools and spare parts, have them in the vehicle when you measure. Also fuel weighs about 8lbs per gallon so measure with a full tank for bump stop purposes. Hub to fender measurement is measured from the center of the tire/wheel vertically to the bottom of the fender or fender flare. Measure on flat ground and measure all 4 corners because they always vary from side to side. Average the left and right measurements but keep the front and rear measurements separate.

What is your goal?

OEM up travel:
If you just want OEM suspension up travel then extend your bump stops by your actual lift height (see hub to fender measurement procedure above).

Extra up travel:
If you want a little bit of extra up travel then extend your bump stops by a little less than your lift height. For example, for a 4" actual lift height extend the bump stops 3.5", or whatever you think is best for you. We think 1/2" additional up travel is great for general use.

Maximum tire clearance:
If you are looking for maximum tire clearance then use an RTI ramp, trail obstacle, or other method to cycle the suspension. You must have your lift kit and tire combination in place to use this method. Simply cycle your suspension to the maximum travel you want to allow (remember to cycle your steering lock to lock). Then measure from the middle of your bump stop to the bump stop pad. This is the amount to extend your bump stops. Remember to consider the worst-case scenario. For example, going downhill will push harder on the front bump stops, or as one tire droops more the other tire stuffs more even after contact with the bump stop (because of the location of the bump stops). So, you may want to add 1/2" or more to your measurement or be sure you measure using worst case scenario. We do not recommend extending bump stops more than your actual lift height (again, see hub to fender measurement procedure above).
