Rear bump stop math for dummies

[travisk]

Here's a bump stop measurement of my rear end just about as compressed as I'd like it to get.

I'm thinking of adding these bump stop u-bolt plates from Dirtbound. I'll still be about 3 inches short. What's the cheapest way to get the rest of the way there? Hockey pucks bolted to the U bolt plate? The extended bumpstops that go up from the u-bolt plate are another 50 bucks.

I dropped my upper bumpstop with piece of 2x2 square stock and added 1 puck to the plate.

I'm thinking of welding a piece of 2"x2" square tubing on top of the U-bolt plate with one hockey puck bolted on top of it. Will that be enough? I don't know how much that stock bump stop will compress.

Hockpucks, PVC(solid pastic pipe), delrin if you have a drill and a bandsaw/portaband and a drill/press you can even make a set of those bump plates. I made my own and it cost be a total of 13 dollars.

I spaced the upper bump away from the chassis with some square tubing. Also, poly progressive bumps are a great low buck upgrade too and come in lengths from 2.5" to 4.5". Much softer than the stock rubber when they hit.

I made my own adjustables, cost nothing!

Here they are with the axle out of the Jeep

Very clever. Putting that on the todo list

This is what I did.

I welded a ~6" long piece of 2x2 straight to the top of the stock u-bolt plate (Hanging off the side of the u-bolt plate about 3 inches towards the inside) angled both ends and used the 4.1" rear bumps up top. Works great.

Cost 20 bucks for the rubber.
