Does the tire clear the front of the frame? Thatís where I ran into issues with mine. Donít forget about flexing too, that needs to be taken into account. Looks good though, carry on.

Nope it does not lol. I will have to massage (or remake) the front horn for it to clear but it won't be too bad. The wheels I'm building with are factory super duty wheels with ~6" of backspace so new wheels will help too.

Nope it was not lol It was a good idea because it gives me necessary tire clearance, keeps the frame side link mounts relatively easy (on the frame rather than hanging from a crossmember), allows for transmission and t case access without having links in the way, leaves good driveshaft clearance, gives me a neutral to slightly negative roll axis angle, and keeps the MetalCloak joints parallel and on the same plane (which they require or could wear prematurely.)

Only drawback I foresee is the tube could bend more under heavy compression force from axle to frame side link mounts (making the links go from looking like ( to < from a top view.) However the only times this thing could see the force required to do that would be a front end crash at pretty good speed. And in that case, I would rather the links bend and absorb as much as possible so I'm good with losing a little rigidity.

That's exactly the reason I think its a bad idea. I'm not an engineer or anything, but from personal experience, it will take a LOT less effort to bend it than you think. You already started the bend. I bet if you hit something with the front end at even 5mph, there will be enough momentum force to bend it further. I had a link like yours, and it bent like nothing with barely any impact.. I think you weakened it like 95%.

Probably not an issue if you are just going to crawl with it, but I personally wouldnt do that.

Just friendly input from a guy who did his SAS dak like 15+ years ago

Nice build though, I dig it. You must be young, because we figured out the Dak was a killer platform like 20 years ago

Huh that surprises me but good to know- thanks! I might add some reinforcement around the bend once I see how my new wheels and tires clear but if I'm honest with myself it'll be hauling the family around more than anything else so I'm not too worried lol.

Yeah im a little late to the dakota party apparently. I was getting my license when you did your SAS and, while I've always loved these trucks, they are finally getting in to my price range for being an unnecessary project truck haha. Thanks for the input- definitely helps to hear from the ones who have done it before!

...my WMS is right about 69-1/2", and my wheels have 3.5" backspacing - best I can determine with 40" tires the only rubbing I will have might be the front frame horn under compression. I think 'wheels' would make a world of difference on your truck Sam.

these are the wheels I have - not sure they're still available but at least it gives the specs etc - https://www.summitracing.com/parts/pcw-98-7981s3-5

Your links will be fine. People with heavier rigs, with more power, that race have all chimed in on this subject and moral of the story is don't worry about it as long as the bend you put into the link isn't extreme. From the pictures it looks fine. Run it. If it bends more than make a new link from bigger, heavier tube.

Hey guys! Been slacking on the updates but have been getting some things done. Decided to start fresh on the driver's side frame...



Would have been more work to patch back in where I had to clearance it haha. Plus I won't have to worry about strengthening it around the steering box and panhard mounts. Also got the motor mount rebuild and the engine off the hoist (again haha). I could have saved myself quite a bit of time doing this before bothering to clean all the old brackets off the frame but oh well haha. Progress should start moving a little quicker from here. Here's how she looks now



3"x4"x.25" tubing in case anyone's wondering. Still need to locate the front body mount on the new frame section but then I'm on to mounting the steering box and panhard
