Haven't you heard? It's not that they aren't in stock, you have to order them to find out if they're in stock. I read a post from big mike about it somewhere, and it all seemed perfectly completely retarded.

Correct, BigMike has been working on revised CAD drawings. But, he's also working on the Standard Prototpye (+2" or 2.5" on each side no MarRack Needed) that caters to a broader market and he needs to get it market ASAP. I can certainly understand that and have to be patient.

Our revised HD Prototype (+3.5" on each side with the MarRack, which performed flawlessly by the way) comes afterward - I think/hope CAD is almost done. Once ready, it's off to the laser cutter, then back to Marlin to finish. I don't have a timeline from Marlin though.

This is correct. I'd rather not mess with Marlin's design on his one and only prototype.

We'll do our best. It's a no-brainer for us if we can get the Spindle/Steering and lower A-Arm fixed.

And the upper control arm/ strut tower looks like it could twist as well . If you look at a spindle from the 86-94 trucks , the the tie rod hooked to a bolt on cast peice. If a knuckle redesign was to take place maybe incorporate this . Easy to change and fast, and would be the weak link hard hit shock absorber for a tire hit. And probably a fawked ton of them from all the sas.
Unfortunately the lower A-Arm is bent backwards at the lower joint. We're going to have to get a new A-Arm that is gusseted at the rear (and a matching one for the other side). While we're redoing the steering on the spindle, BigMike will also be incorporating 3-4 other enhancements to increase downtravel by 3-4". So it's more than just the steering unfortunately.

Most likely it's new Lower A-Arms and Spindles (with a revised HD Steering setup) on both sides. I then put on some longer limit straps and see how much more travel we can get.

We're pushing though! it's not fun to see the car just sitting in the garage!

It's the best kit out there IMO - and Marlin doesn't ask me to say anything but the truth. Ours was a Prototype, so we expected KOH to show some weaknesses. More details can be found here:
Marlin Crawler's New Rock Crawling Long Travel IFS Suspension System (#RCLT)

It's worth of noting that I contacted 4-5 other Long Travel Front Suspension Manufactures early in the build process and none were willing to put their product on a KOH bound vehicle. They all stated that their systems weren't "made for KOH level abuse". Marlin was the only one raising their hands.

Note that I added a post at the end with full disclosure on everything we saw that needed to be fixed:
1) Strengthening the connection point for the Steering End to Spindle to avoid any future failures at this connection point.
2) Reinforcing the Lower A-Arm with a gusset at the rear lower side for potential high speed impact.
3) Shaving the width of the spindle in the middle areas to avoid contact with large diameter 2.5" coilovers, thereby gaining anoterr 3-4" of downtravel
4) Shaving a little more material off the lower Coilover mount on the A-Arm so large Gen II RCV boots clear it easily at 28 degrees.

I promise, BigMike knows when the AOP race is

3-4" MORE droop? It looked maxed out in your earlier pics.

Was thinking the same thing. I know they said the spindle hit coilover coil spring at droop but it looks like the axle/cv is already into the lower a-arm and wouldn't allow it to droop any farther anyways.

We had to install shorter limit straps to keep:
1) The Coilover from hitting the spindle
2) The RCV Boot from hitting the Lower A-Arm

Marlin is working on changes that will prevent both from occurring in v2.0. Our RCVs are rated for 28 Deg and we're at 22 Deg at the Limit Strap now. We think we can get 3-4" More Downtravel in the Front with these changes. With all this said, we can artificially limit it some just in case.

Note these changes will match the 3-4" More Uptravel in the Rear from bending our upper links and raising our Air Bumps. However, the Front will still likely have more travel than the rear, which is less than ideal but it is what it is in light of our 4600 Class Limitations.

As a quick update, our Prototype RCLT front suspension is all off and will be shipped back to Marlin this week in anticipation of v2.0 in March:

awesome.

I will say that the videos posted on facebook were well done also.

it would be nice to upload them to youtube or ugetube and link those to the forums, not everybody has facebook and it is another simple way to help get more exposure areas.

keep at it, glad to see updates

You have 28 degree in the CV joint. Now is that 22 angle with wheel straight at droop or turn full lock at droop. The combined droop/turn will add to the angle. I would be surprised you get more than 1 or 2 inches droop but anything will help I'm sure

RCV said the shafts can take 30 Degrees at full droop, but recommended not going past 28 degrees. We were measuring the angle of the shaft at full droop (on the limit straps) with the will straight.

Yeah, we'll take anything we can get!

Our 4Runner was chosen as the 2nd Most Innovative car at KOH 2019 by Offroad Extreme, only behind Jordan Pelligrino's IFS/IRS car.

Nice to have some additional exposure for our team and sponsors!

Sounds really impressive until you look at the list and see that the 3rd Most Innovative car at KOH was this.

Cool build. Missed you out on the lake bed though.

I saw this pic and thought, must be mocking up the steering arms to test for clearance. Scroll down 1/2 a page, bummer. You guys were getting after it.

NOT SURE WHY PICS AREN'T SHOWING UP...

Quick Update: Here's what we've been waiting on - straight from BigMike at Marlin Crawler:
https://board.marlincrawler.com/inde...essage=1163197

We've been receiving regular updates from BigMike at Marlin Crawler over the past few months since KOH and are really excited to see his announcement of their RCLT v2.0 Kit.

Even better - the first version of v3.0 of Marlin Crawler's RCLT kit that he hints at in the posts is coming to our Steel City Racing 4Runner in a month or two. Can't wait to get our hands on RCLT v3.0 and finally get the 4Runner out of the garage!







Also, a few more technical specs and details can be found in BigMike's personal build thread here:
https://board.marlincrawler.com/inde...180#msg1163180

And some pics of his Tacoma on 40's with RCT v2.0:










As a side note, while we've been waiting for RCLT, we stripped the interior, applied a finish coating to our roll-cage and all steel work, re-routed our fuel lines to get rid of some excess hose, and are working on a few small upgrades including looking for ways to cut weight.

We also have a few more upgrades planned with RockSolidToys and Otwell Fabrication for KOH 2020!

More to come...

We didn't make AOP, although we really wanted to! See post above for updates.

It sadly hasn't left the garage since we got home from KOH. Anxious! Should be getting our new front suspension in the next month or so, then we can finally get it out again!

We looked for you are the AOP race, but understandable when waiting on parts. Seemed like the racers enjoyed the tight woods etc of that race and seems like Ultra4 will be back there again.

Get your parts in and installed then head up to the Dirty Turtle race in mid-July.

Steering looks nice. Front of the lower a-arm looks like the next area to take hits. Could it be rounded more?

Was just looking at stuff on total chaos and they offer a weld on kit for the upper control arm /shock mount area . It makes it double shear mount. This runner should have these ,for 105$ for them you would get rid of the next week link .
