Last year a friend of mine called me up and really really badly wanted to get rid of the leaf springs in the front of his truck. Turns out it was the Rock  Ape from Pirate back in the day. I always liked that thing. If I remember the guy built it for TTC the year I went. Anyway the story goes he had bought all his parts from another shop so he apologized for that which didn't matter but he had some disagreement with that shop blah blah he needed a place to do it.  So the deal was he helps I design and we did it over 2014 Christmas holidays. This was kind of hobby like and not work for me.

He had brackets from Blue torch but the centers were the wrong width so we cut new ones  to seize them for the ballistic joints the other shop had sold him.  It was fun because I never get to see other parts. After seeing those things I realized what china has done to the world.

As the deal went he removed everything. The leafs mounts etc. The boat side made things interesting

I acted as more of a guide than anything. However knowing where to put things and how to build them is a big deal. You can buy DIY brackets and stuff but you don't really get the proper set up. It's like going to macdonalds and ordering a burger and fries or going to the store buying a steak and bar b qing it. Sure you had meat for diner buuuut it a bit different.

And as usual a simple "just throw a 4 link in goes south. Thought we could use the old shock hoops but no. To top it off the orbital etc was smack in the way. It didn't help that Brett wanted the diff forward just a couple inches. Sounds easy enough but it opens a whole can of worms.

The other nice thing and reason I agreed to the truck coming into the shop was Brett did the welding.  More or less my shop was a U wrench with an on staff technical guide.

Belly bars were all made out of 2" .250. I just don't see the point in building something holding 2.5 ton axles to the bottom of a rig being made light.

The bracket were pretty beefy as well.

His frame was like an 80's chev and they're a pain in the ass because the rails are so narrow. It's hard to place the links proper without frame contact while getting a decent amount of triangulation.

So we made a little different mount set up.

It looked pretty wild with the boat sides

Hours of test fitting and twisting to make sure everything was clear and to figure out where the shocks could be placed without contacting anything and that I didn't screw up placing the links. Watching the pinion motion and drive shaft growth.

If you've ever been to my shop you've probably met race kitty. She makes sure we're doing everything right. And that our necks don't get too cold.

Had to make a T-case mount that could be removed leaving a flush surface so the tranny - t case removal wasn't as much of a pain in the butt

The cantilever super gusseted shock tab.IMG_5054.JPG

 

IMG_5075.JPG

 

why? good question because your shock should never see more force than the spring. Your bumps should be set to stop the shock from bottoming out. But what if something happens. Say you lose the bump and don't notice. I see many many many hoops with the chunk of .120 wall tube missing where the mount was. Might as well create as much surface area as you can.

and the really crappy hard to get to spots. yes I got to weld those.

 

 

IMG_5088.JPG

 

 

 

Then I looked at the 54's and figured we should beef up the knuckles. I know theres plates guys make that slip over and weld on easy but they're ugly and I've always had a knack for plating. Since it was here I figured why not.

Too much is never enough. Always after that surface area to help disperse the energy in a huge hit.

A little steering geometry.

cutting it close on this one

 

IMG_5096.JPG

 

Trying to set up the ram mount with max ground clearance but also protecting the ram rod as much as possible things get tight quick. One nice thing about the ball socket it doesn't have a nut and bolt sticking out to catch on the tube if it rotates.

normally I'd probably plate it but we were in a time crunch. The tube is 2" .250 so it's pretty tough as it is

Some tie down points for trailering

 

IMG_5105.JPG

 

You can see the sheeted in gussets I put on the support tubes. This is to prevent the ram mount from bending up. Not that it would but it could but it can't now so it won't.

Also I did sheet it in under the ram back to the housing. Always paranoid that the mount could get banged and shift to the side.  Maybe I over think.

Ya know it'll probably collect mud but I'd rather it be rock solid than bend. If I know one thing guys will drive their stuff into a rock block at 60 and wonder why something bent or broke.

Ever want to kill a pump? This is a great example. Remember the pumps are gravity fed they don't suck. So pointing up hill this would probably cavetate the pump pretty quick.

Not sure if anyone else has issues but these crack here all the time. Pain in the butt

and then there was the orbital mount

Not to long ago I recall just move the diff forward a few inches. Hahahaha I'll never learn.

Then came the bump stops. To full bump the rig goes.

 

 

 

IMG_5132.JPG

 

It never ends

 

IMG_5133.JPG

 

 

It never ends here either

 

IMG_5134.JPG

 

So much junk in the way and with the chunk, 54's, motor and body dictating the ride height I think the can has to sit here.

Since these things are supposed to take the brunt of things at the bottom of the travel preventing your shock mounts from being torn off and your shocks being mushroomed on impact I went nuts on gussets and lateral support. At the same time it helped stiffen up the frame.

once again way overkill but why not. Instead of plate I went with tube. Once more each point is transferring energy out across the rest of the chassis in as much area as I could make it.
