Not only am I going to book mark this for my rig but I am going to pass this along to my buddy with a Colorado. You think our mount is bad the one on the leaf pack of the Colorado is obnoxious.

I hear ya. I've seen the mounts on the Chevy and the Nissan's, not the best design of off road travels.
 
looks like it might help protect drive shaft too?

They may depending on the ledge you're trying to climb or descend. I hope to give them a work out in Moab next month, we'll see.
 
Great work ! This mod is definitely in my future.

question for ya guys that have done this...

my rig is almost stock for lift, but running 35s and i hang on these all the time. my LCAs are almost parallel with the ground for ref too.

i need to beef them up somehow, so im torn between just welding plate on the existing mount or making one of these little sliders. so my question, would you rather have the mini slider and have contact with it sooner than the mount thus delaying contact with the tire, or would you rather have the original mount beefed up and have tire contact sooner?
 
I have been asked to post this up by my buddy, the #2 parts on MUD everyone knows as Beno.

I had given this a fleeting thought quite some time ago and never pursued it because it wasn't holding me back on the trails I was running. Finally after two plus years of getting hung up on my lower rear control arm forward mounts I had to do something. I searched MUD an found no mention of what I was looking for, heck I was surprised not to see something similar on Shortbus or some of the other more extensively built 80's. At any rate what I came up with is a ramp/slider which substantially decreases the approach angle on the front side of the rear lower control arm forward mount. My initial design years ago was this crude drawing and used .25" plate with a fitted webbing to provide strength:

After this past season of wheeling of getting hung up repeatedly it was time to correct the nagging issue before Disney, OK, South Dakota and the rest of the season. While at the steel lot I found a cut-off of 1.5"x1.5"x.25" box tubing which I figured would more than adequately fit the bill for such a heavy truck. What I ended up with is what you see below. As luck would have it the length I went with once cut to fit nearly matches the same angle as my lower control arms (bonus) making for a smooth transition from frame to control arm. An added bonus which I hadn't paid any attention to while burning these on was that these sliders hang below the drive shaft and may provide some added protection when playing on ledges.

I you have access to a welder and a grinder this might be something to consider if you wheel your rig in the rocks and such. For a half day or less of puttering in the garage it'll be worth it.

This is an awesome idea! I'll do it on my truck. two trips off road. and one of the brackets already got hit hard.:cheers:
 
You need to address the fuel tank now. I know that aint good for a tank.

The Fuel tank/lines should not be an issue. The tank has a cover and the welding is not that close to generate heat to the tank or lines. :cheers:

I didn't think about the fuel tank being in the way since I have the 1" body lift and the tank attaches to the body.
 
Bringing back an old thread here.
I keep getting hung up on those dam control arm frame mounts.
Will adding some type of slider like this really help?
To the guys who did this awhile ago have you noticed any difference in getting hung up, has it helped?
What about rasing the frame mount to tuck it up more closer to the frame?
I hate getting hung up on these things.
 
Wouldn't a larger end create a bigger catch point?
I see what your saying that the larger round end would be you slider and keep it off the mount and slide over easier because it is round correct?
That is the problem with the east coast it is the boulder field runs and a big fat 80.
I was out doing some redneck measuring today and you could raise the frame mount about 2 inches before you get into the gas tank but it would be alot of work.
I might try the little slider route.
I am waiting to see if anyone who has done this has benefited from it at all.
Nothing is more annoying than getting to the end of a good run and then beaching the whale on those darn frame mounts. And in most cases there is only one line through there with trees everywhere.
 
At some point you'll hit something on the frame. Yell at your spotter and get bigger tires. :D
 
Bigger unfortunitly is not the answer for me not in the budget.
Plus we are usually running with no spotter because I am always following around those dam truggy guys and they drive right through and then comes the big fat 80:grinpimp:
You west coast guys for the most part have nice hard wide open trails, not here everything is tight.
 
It has helped a lot, no question. I consider this a basic mod that all crawled 80's should have - it both protects your mounts and improves performance for very little cost.

The 80 is still compromised in big rock gardens. The entire frame is too low, so you want to do what you can so that the LCA mount isn't such a rock catcher.

I also have large eye ends (Slee arms), which just means those ends are really beat up :hillbilly:

Run 37's if you aren't already. You'll be shocked at how much your 80 is finally not rock dragging all the time. I haven't candy caned my rear driveshaft once since going to 37's, and while I still get on my sliders that's just a reality at 4" of lift.

No question our trails are wide open :D

I have to run 35's for now I put almost 400 miles a week on the truck and I am not ready to regear and go to 37's yet.
Plus I am finding that 4" of lift and 35's does really well in the tight crap we have here in the east
I have not caned the drive shaft either.
For the most part there is nothing wrong with alittle skinny pedal and a good bump to get you through got to follow those truggy guys in the fat 80 they hate it:hillbilly:
I am going to put on those little sliders and give them a go it can't hurt.
