    Extend your bump stops with our custom length bump stop spacers (price is per pair). We recommend extending your OEM bump stops because simply put, they are the best bump stops available short of expensive pneumatic or hydraulic units that require lots of custom fabrication to install. The OEM bump stops are very progressive meaning they are very soft at initial contact, but get progressively firmer to stop even the hardest of hits without brutal, part breaking, metal to metal contact. The best part is they are designed to be used without even knowing it from the driver's seat.

    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 they 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 measurment 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 measurments separate. Hub to fender measurements on a stock WJ Grand Cherokee are about 18.2" rear and 18" front. OEM distance to the start of the bump stop is roughly 1.5"

    What is your goal?

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

    Extra uptravel:
    If you want a little bit of extra uptravel 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 uptravel 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 drop 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 (see hub to fender measurement procedure above).
