Is there an easy way to extend bump stops?

travisk · Mar 12, 2013

As you can see from the video, I've got problems with my fenders. It looks like the factory bump stops are quite a ways from doing anything useful and the sheet metal on my XJ is suffering.

Yes, my wheels are a bit offset, but I like the stability. I don't want to trim the fenders any more, as I'm already on some sort of mud flap violation watch list with the local cops.

Is there an easy solution to this that doesn't involve fabricating? I'm not afraid to spend a few bucks for something that works, but I'm a just a semi-competent bolt-on kind of guy.

ive used stuff called goop befor, can be found at wal mart or a auto parts store, or you can drill and tap the coil buckets and bolt them in place

Mud flap violation watch list. I didn't know lists like that even existed. Lol

or just buy 4 hockey pucks for $4 compared to $32

travisk, start of with 4 pucks per a side, remove or add as needed

the issue with just hockey pucks is that then you have a bolt sticking up above them that will chew up the stock bumps.

and you will eventually destroy the pucks with the stock bump towers.

the RE units have a recessed hole for the bolt and are a much harder plastic that will hold up a lot better to strikes.

a large masonry bit or a razor blade can also make a recesed hole

How much do the factory bump stops compress? Half an inch?

rockclimber · Mar 12, 2013

they should compress almost all the way into the cup.

depends on age the ones in my 95 completly folded over to the point that the pucks were touching the metal

Where can I get pucks for $1 each? Just curious, I've been looking but haven't found any that cheap.

doing that will ensure that you split the hockey pucks much more quickly.

If you plan on pulling to coils, do it right. Measure how much and go from there. Prothanes will be your best bet. Otherwise, I used pucks with black RTV and they didn't move until I ripped them off with a pry bar when I swapped axles. You can insert them without removing the coils.
If you do use pucks and drill them, a slight countersink will be just fine. ACOS or air bumps work great as well.

Daystar also makes extended bumps that replace the stock bumps, but also require at least partial removal of the coils.

how do you plan to drill and tap a hole without inserting the coils?

i have the RE 2" bump stops. ive since added 2 pucks under each side. next time the coils are out, i plan to score all of their surfaces, and JBweld them all together. ive already had a couple pucks split.

I don't. Johnny Walker said he used RTV and eventually he had to pry them off with a crow bar.

Is there an easy way to extend bump stops?
