Bump stop extensions for only 1" spacers?

[WrangledMyselfIntoThisOne]

Are bump stop extensions necessary when using only 1" spacers? I plan on putting two .5" Teraflex spacers on the front of my Rubi for 1" of spacing, and one .5" spacer in the back, for some extra leeway if I want to add a rear steel bumper. Since I really like the stock height with my 35s, my main goal here is just to even out the stance a bit, but I figure might as well add a tiny bit of height too.

The problem is, the only bump stop extensions I can find are 2" in height, which seems excessive for a 1" spacer. For the rear I feel like at only .5" I can get away with no bump stop extensions, but do you think it'd be safe to not use any bump stop extensions for the front 1" spacers, or is that dangerous territory? And if you think I should use them, does anyone know where I can find 1" bump stop extenders?

No you will be fine, but I wouldn't add much more than that. Maybe 1.5" max. If you're worried about it just ramp your jeep and make sure there are still gaps between the coils at full stuff, that's all you need to look out for.

For future reference, hockey pucks make great bump stops, they are 1" thick and you can stack them to get the height you need.

Synergy makes stackable bump stops that come in 1" increments that you can adjust easily. Rock krawler has some as well, but I think they're more difficult to stack.

From how I understand it, there are only two reasons to change the bump stops and both don't apply to your situation:

• If you are running any tire larger than 35" (on a Rubicon) and want to keep the tire from contacting the inner fender.
• You have shocks that have a longer compressed length than OEM.

A third reason is if you swap in springs that have a taller (longer) compressed limit.

Ahhh of course.

Any idea what the max compression on OEM springs is? Adding a 1" spacer obviously changes this, probably not enough to cause issues... but a 2" spacer might.

Best practice is to add bump stop height equal to the height of spacer you add. (At a minimum)

This will keep you from over compressing the spring.

Lots of companies sell stackable bumpstops. Synergy, Metalcloak, and the like.

If you don’t wheel then it won’t be that big of an issue.

Have installed Rubicon x wheels and tires on my stock JLR. Tires are 315 70 17 BFG KO2s. Flexed out, without disconnecting sway bar, the left rear tire very slightly rubs on fender lip. I will probably add 1/2” or 1” spacers on all four corners. I am wondering whether I will also need to install bump stop extensions. If so, the smallest extension I can find is 1”. (Because my wife and I are not tall, I would like to install the 1/2 spacer, but I am not sure if this will be enough for my set up).
