My 40 Dodge Truck Build - Maybe a 41 LOL

[Couper]

Finished my rear brake line today....now they are all done....lines, clamps ect
As you may be able to see in the pics I've gone from my rear calipers with a custom hose to a tab I welded on the axle tube, then to a hose assy from an s10 blazer for the center rear drop. The hoses and the hard lies run on top of the axle tubes. After done, I started thinking about busting or loosing a coil over shock. (not sure if that could happen or not) but if I do, the top of the slots in the bed sides for the axle will contact / cut the hoses in half. I determined this by taking the shocks out and slowly lowering the frame down. I'll need some suspension bump stops to protect the whole she-bang. Normally the bump stops would contact the top of the axle tubes....or at least they do on my Dakota.

I'm thinking about going from frame rail to frame rail at the kick up just in front of the proportional valve and bump stopping against my upper 4 link bars. They are very heavy duty at 1.5" dia and I believe 1/4 wall. It won't run on these stops and they would only serve if I were to break a shock..... Not sure if you can see this in the last pic but it's all I seem to have.

Whatdathink?

Nice clean job!!!
I run my lines on the back of the axles then over the center section like you. The rubber lines are on the back and roll up to the calipers after going under the frame.

Thanks OI. I wish I would have thought to run them on the backside of the tubes, then I could bump stop on the tube. I think the upper 4 link bars will work as well. It's just protection should I blow out a coil over. I'm anxious to get this frame in paint!

So great to see you back "in the mix" Coup. I know it's been way too long in coming for ya but enjoy it for every ounce ya got!

I don't believe I have ever heard of coil over springs failing without a bit of warning (and those were on dirt track cars). The only concern I would have (and it would be pretty small) might be the possibility of the upper or lower coil over mounting bracket failure (an upper coil over bracket failure would be a larger issue then a lower bracket failure), and I believe that too would give you some advanced warning.

I see you have both ends of the coil overs mounted with a single shear bolt, which is how most street driven coil overs are mounted. In the dirt track racing world, most mounting brackets for coil over mounting brackets use two brackets with the coil over mounted on a bolt passing through both brackets. Probably an over kill for such a light weight truck on the street.

If all you are concerned about for the bump stop is the coil over failure, can you bend the steel line away from the axle center line (only where the bump stop is) and then add a bracket on the side of the frame to mount the bump stop to? A rubber bump stop won't cut a steel brake line, probably won't even pinch it closed.
