2019 SAS 5th gen Build

[4rNCMTNs]

Today #wheelin_ with_willy got all the rear links and frame supports welded on and started on the front. Tomorrow morning the front links should be installed. And we are hoping to have the truck on the ground under its own weight on Saturday as well as finish as much of the steering as we can.

I had an exchange with RCV this morning, and there is a glimmer of hope that we will get the shafts in time for ATR. At the moment they are out getting black oxide.

Going to be a great Friday and Saturday. The balance of our steering parts arrive today which is 2 days earlier than expected.

This is the steering pump and check valve for the hydraulic steering.

The front four link is just about done. Tomorrow will do my best to get a video of the 4-link in the front and back and post it.

The 4 links suspension in front and back is now complete. Some additional welding needs to be completed but it has been put in and tested. The shocks will be installed by the middle of next week.

At this point if I remember correctly we have around 4- 5 inches of up travel in the front and 6-7 in the back. The down travel in the front should be around 10 inches and the back 12 to 14. Once I have all the final numbers on this I will certainly get them corrected.

We have a lot to finish but we are approaching the end of this final first stage of the build.

Early next week the new steering pump will be installed and then the rest of the components for the full hydraulic steering will be mounted and lines run. Also need to finish up rerunning new brake lines as well as the air lines for the lockers.

Some additional gusseting needs to be completed and there is roughly two full days of welding for that to be complete.

Obviously the photo below is not at ride height we were just looking at the flex.

What are you doing for transfer case?

What are you doing for transfer case?

I'm going with an Atlas 4 speed with 10.34:1 bottom ratio. When I ordered it in early June, it had an 18 week lead time. Therefore it should arrive in middle of October. Really looking forward to receiving it.

Is this the first SAS 4 link 5th Gen?

Damn those tires…

So much beef, I love it.

A quick early week update

Yes, this is a stout build no doubt about that.

Yesterday #wheeling_with_willy did about 8 hours of welding and adding a lot of gussets.

The last remaining brackets, limit straps, and a replacement link to now have a aluminum spare in place of the steel one we had planed on were ordered.

Also got a carrier bearing for front drive shaft ordered. The drive shafts should be completed by Thursday morning and ready for installation on Friday morning. We are modifying the stock drive shafts for now until the Atlas install. Therefore we have to change Toyota flange to the 1410 on the input side of each.

Shock towers should be delivered today or worst case tomorrow as they are coming from Barnes which is only a few hours away. The rear is already cut and ready for installation of the towers. The front position was determined on Saturday and will sit just in front of the master cylinder on driver side and my compressor install on the passenger side. So our preemptive removal and relocation plan for the fuse block and washer fluid seems good. So now fuse block will go where original batteries were installed and the air box front passenger where the washer fluid was. Some of the steering components may also go in this area, for example the steering fluid reservoir just behind head light and in front of the air box keeping a very short and straight path to the steering pump.

Gas tank was also ordered yesterday from someone local and it will be delivered today. We were going to go with an 18 gallon tank but settled on a 16 gallon tank. The 16 is wider and less deep so better clearance in the back. It will be tucked between the frame rails with a skid plate under it. Finally a bracket to install the Howe steering pump was designed and should be cut this morning.

Speaking of clearance, in the next step or two we will cut the back bumper
and rear of frame and build a tube bumper to further increase clearance.

It's going to be a lot work between now and next Tuesday night but I have sourced a 24' trailer and we are committed to take it to ATR regardless. The wildcard is going to be the front RCV's. I will know on Thursday the status of them.

Shocks are going in today. Here is the first front shock mount put into position. They will all be tacked up today with the shocks mounted to measure for the springs.

So within the end of the week we will have the shocks fully mounted with all springs installed.

Front and rear drive shafts are being worked on today and we'll be done tomorrow and so on Friday we will also install the front and rear drive shafts as well as the carrier bearing

Looks like a beast! How much weight do you anticipate all of this will add, and what will be the effect on engine performance?

Not sure yet where it will finish in terms of weight. we have removed a lot and added a lot. It was just about 6150 when I dropped it off so I would imagine we will finish around 65-6700#.

The engine isn't the issue as much as it is the torque converter/tranny, transfer case, gearing, etc. I have 5.13's gears and will replace the transfer case with the atlas so that would leave the torque converter in stock tranny as the most likely weakest link. However this is not a race car and will rarely if ever be driven on the highway any longer. I'm confident with the supercharger and gearing I will be just fine.

so happy - axle shafts

I have been worried since June we would not receive our axle shafts from RCV in time for ATR next week.

Well yesterday after one week of waiting for some good news, it finally came and the shafts shipped yesterday. Tomorrow morning I will get a video of them posted of these beasts. They are the last thing required to finish this monster front axle. So a huge should out to #RCV for getting them done on schedule as promised back in early June.

I think the only thing left to source are the brake lines and I do that locally this morning. It's nice to live in the middle of NASCAR and other racing shops. It makes sourcing parts rather easy.

Below are a bunch of photos from today.

The suspension is close to full droop in front and 2-3 from full droop in the back.

Order 5 pairs of springs to make sure we get the correct mix. Right now 250# in front and 150# on back. We can return whatever we do not use.

Tomorrow the steering will just about all be mounted and serpentine belt reconnected.

Most likely will change to cone type air filter.

Tomorrow will also slightly change rear shock towers and french them info frame.

If all goes well will paint everything on Monday and get it all back together on

It's completely together so much that I picked up a 24' trailer to tow it to ATR next week. If all goes well we will test it on Wednesday to start getting used to it and a little more Thursday morning and the fun stuff. If it rains as forecasted it will be a sloppy fun mess.

Very bizarre IMO. It will be interesting to see how it performs.

What do you find bizzare? It's a 4 link suspension nothing bizarre about it. videos of it performing should be uploaded starting next wednesday.

 

[Dr.Jett]

This thread wins the “thread that delivers” award. Every time I open it there is minimal BS just a jaw dropping display of pic heavy mechanical madness. I actually hate that my post disrupts that flow.

Probably the extreme nature of the build on a new, supercharged 4runner. Not the donor vehicle that most people would use for something like this, but that's what makes this build interesting. Lots of people put 4links, big axles and tires under TJs and Toy Trucks, not many doing it on 2019 4runners. :rockon:

I can agree on that 100%. I just accelerated the build process a "little" bit. It was certainly very capable in it's previous form, not it's not just a different story but a completely different book.

I could have used my '10, but it's my wife's vehicle so that wouldn't be nice, so I had no choice.:bounce:

i was going to say the spring rate is bizarre. but its a rock crawler, not a go fast desert toy so i'm clueless....same thing with the uptravel vs down travel. wouldnt you want ride height to be close to center on the shock travel so you have lots of up travel and down travel?

genuinely asking, as rock crawling is a whole different world



Awesome build, a thread worth checking the forum for lol
