Default Re: Anyone have another solution for extending bump stops?

On my H2, I used stock length shocks and shock extensions. This made it a necessity for me to extend my bump stops as I would now bottom out on the shocks harder than I would had the bump stops still been there to slow/stop the motion.

However, since I used shock extensions I was able to get away with using a spacer between my OEM bump stop & mount. Here is what I made to take up the 1/2" space between the control arm and bump stop:

Default Re: Anyone have another solution for extending bump stops?

On the H3, I used the longer Cognito shocks. This allows me to "bottom" all the way down to where it did from the factory. However, the bump stops are not touching as they did from the factory. This causes me to have more body roll, nose diving when braking and getting blown around by side winds on the highway.

Can anyone confirm if the factory stops are pressed in or held in by a screw or bolt? They appear to be pressed-in, but there is also a hole in the center that may have a screw/bolt through the hole.

It may be possible to make a spacer similar to what I did on the H2 and run a longer bolt through the spacer into the frame or bump stop mount.

The oem bump stops are pressed in.

Default Re: Anyone have another solution for extending bump stops?

I haven't looked but is there a hole in the top of the mount? If there is, a ball joint press or similar could be used to press the oem one out from the top if there is clearance. Anyone have access to a factory service manual? There should be a procedure in there for changing the OEM ones out. Once you get the lower a-arm out, and the bump stop out of the hole, seems like that location could be very easily modified to fit either a spacer or an aftermarket bump stop. With the variability in construction and materials, you could probably even do some on road suspension tuning by choice of bump stop rate.
