Something I can't quite grasp. You lift the JK X amount. Then you go put on bumpstop extensions that are X amount. Haven't you effectively negated the additional travel that you just added?


They say to add whatever amount of bumpstop extension as lift you just added so... is the lift then just for looks, and for clearance, if you add longer shocks (which from material I gathered on here, is what really gives you more travel, then you add bumpstops, don't they cancel out.

Color me confused.

 

You can actually over extend the axle and damage other components

 

bump stop extensions are primarily designed to help prevent the over compression of your coils. added benefits is that they help prevent things like fender rub as well especially being that a taller lift usually comes with bigger tires. in terms of articulation, your taller lift will also come with longer shocks and they will allow for a greater amount of droop. bump stop extensions will not cancel this out.

 

Got it. Compression Up, Droop Down, Bumpstops prevent damage from the compression (up movement of the shocks) the longer shocks allow for extended down travel

 

Yes, but once in a while you find springs that lift maybe 4" and only require say a 3" bumpstops extension. Usually a kit gives you what you need, but if you start looking at springs and their manufacturers recommended bumpstops you can sometimes pick up a bit of uptravel too. (Likely only an inch or 2.)

Take for example the teraflex 3" kit, which gives a bit over 4" actual but includes a 3" bumpstops extension.
