homemade rear bumpstops

[JAlVl3Z]

I'm looking to build some rear bump stops. Please post ideas and/or pics. Thanks!

How much extra bump stop do you need?

I went with a 2" sq 1/8" box tube which I bolted to each side of the frame where the old stops were, then I bolted a set of OEM Upcountry bumpstops to that. so that gives you some 3" more bumpstop.

I forget exactly how much longer the Upcountry ones were, but it stands to reason that if you went up one inch, than the bumpstop might be 1" longer.

If you search around here, you will find different ideas from extensions on the upper leaf plate to a complete rework of the suspension for coilovers.

I think the cheapest way to do it is to pull the U-bolt plates and weld some square tubing on top of it. Then you can add hockey pucks to adjust the height. The puck should meet up with the stock bump stop on compression.

Currie makes their own version for $179.

DirtBound makes a simpler set for $50 pair:

Here are mine.

Here is what I have been using for the past several years.
The bumpstop bolts were replaced with all-thread.
4-1/2" urethane bumpstops, from Summit, replaced the stock bumps. The inside edge of the new bumpstops were trimmed, at an angle, to soften them up and to provide greater compressibility.
The new bumpstop are shimmed downward, using shims cut from a 7/16" thick plastic kitchen cutting board.
The combination of thin shims and the all-thread makes adjusting the height of the bumpstops easy.
I use small zip-ties, tied on the shock shafts, to check for maximum up-travel. I like to leave an extra 1/2" or so of unused shock up-travel to protect the shocks when the enviable extra hard hit occurs.

I like rear bumpstops that won't destroy my u-bolt plates and leaf pack.

Those leaf spring plate tubing extensions that are not supported underneath WILL bend under hard hits...

Ive bent 1/4 wall tubing....

I've put a few hundred miles in the dirt on mine and they're fine. I will try harder.

progressive poly bump, spaced from the plated rail.

dpg adjustable u bolt plates underneath.

worked fine for years, had a slight bend to them after I was done.

1.5" OD tube .25 wall (1"ID) welded a 1" grade 8 nut to the top, welded the bottom to the axle tube. had a 3" circle cut out of .25" plate and welded that to a grade 8 1" bolt.

top bumpstops are energy suspension poly tall bumpstops that fit in the stock location.

They work great and are easy to adjust!

yes, I know I need to trim my u bolts but I need a little more lift so I'm not going to trim them until I'm happy with my spring packs!

mine: Seem to work fine so far.

Rec tube with a large washer welded up the top. Nut welded on the backside of the washer.

Bolted on the top delrin bump pad to the bottom stop.

I have some custom extensions made from box tubing that bolts in between the stock bumps and the frame like some of the above.
