How tochoose the length:

Actual lift height:
It is very important that you do not use themanufacturers advertised lift height for any calculations. Always use a hub tofender measurement with the vehicle loaded the way it is typically used. If youusually 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 bumpstop purposes. Hub to fender measurement is measured from the center of thetire/wheel vertically to the bottom of the fender or fender flare. Measure onflat ground and measure all 4 corners because they always vary from side toside. Average the left and right measurements but keep the front and rearmeasurements separate.

What is your goal?

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

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

Maximum tire clearance:
If you are looking for maximum tire clearance thenuse an RTI ramp, trail obstacle, or other method to cycle the suspension. Youmust 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 (rememberto cycle your steering lock to lock). Then measure from the middle of your bumpstop 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 willpush harder on the front bump stops, or as one tire droops more the other tirestuffs more even after contact with the bump stop (because of the location ofthe bump stops). So, you may want to add 1/2" or more to your measurementor be sure you measure using worst case scenario. We do not recommend extendingbump stops more than your actual lift height (again, see hub to fendermeasurement procedure above).
