If you choose a custom "non-stock" length, please allow 5-10 business days to ship.
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).
