a few missing details, but i think this chassis is close to wrapped from the firewall back. now time to focus on the front. the odd channel brackets are for saddle style fuel cells.

i think that's pretty much a wrap! got all the IFS crossmember mounting dialed in and the frame connectors built. now to start detailing out drawings and such to have all the plate cut.

ordered all the steel for the chassis today! was $536 delivered from MetalDepot.com, $527 picked up locally, or $385 picked up an hour away. i'm driving for it!
tires get put on the wheels Tuesday, that's when i can final double confirm the chassis and start the fab. had to move the rear most bags inboard b/c of a wheel clearance. Colin said he could cut all my plate early Jan, but that shouldn't hold me up at all getting things together. ![]() |

started actual chassis fab yesterday with the tube work. got everything bent, notched, and cleaned up. even bent up some stuff for a buddy to build a TJ belly pan / engine skid.

Did you model the engine and rear end or was that sourced from somewhere?
Looks pretty sweet!

What kind of joint do you use between the diff cover and that z thing to have play due to the fixed mount on those "lower" links?
What do you call that style suspension? |

Watts link suspension! Basically does what a panhard bar does, without any lateral movement of the axle with suspension travel.

just to try something different, and because i wanted a lot of suspension travel with the tires tucked tight to the fenders, i went with the WATTs link instead of the panhard bar. over 15" of travel, my links induce only about 0.07" lateral motion. it has standard poly bushings on the frame side of the links and heims at the pivot link. the center pivot is a big-ol Johnny joint. was easy to fab with, and allows the link to rotate some with the travel while still being a stiff joint. when i was designing it i went back n forth with Sean over that fact that it being able to pivot could also induce some extra lateral motion. per the geometry, it's less than 0.1" so i suspect no bad effects. but i've been wrong before, and we are going to find out! that part of the suspension i designed and built in 2017 ![]() ![]() |

got the chassis wrapped up in 3D and got the steel a few days ago. did a quick mock-up for motivation and to check a few last minute dim's before cutting the last chassis in half to save a few bits. the C30 IFS is 3"+ narrower than the ram suspension currently under the truck. the mock-up picture is at that chassis' max drop, what should be about 3" below ride for the new chassis. not going to say i'll never rub a fender with the tire, but shouldn't be too bad.
i'm also super glad that i'm taking the time to properly slam this truck. i think i'd have always been pissed driving around with that as my max drop. having spend all the time building to have only gone half way. ![]() ![]() |

So are the rockers going to touch the ground on the new chassis? Thanks for the build thread, it is motivating me to get out in the garage and work on some projects. Also this is further fueling my want to build a jeep cab ramp truck, that will sadly have to wait til I have a different house, I have nowhere I could park or build something like that here.

go build! i'll race ya to first drive.

as of the mock-up, i'm hoping to set the ride at about 8" above bump for more steering clearance. really there shouldn't be anything mechanically limiting me from that, but we'll see how it rides and the geometry changes once aligned. Last edited by 6DoF; 12-14-2020 at 07:33 AM. |

did some smashing on steel this weekend to get the huge sticks off the floor. even remembered to lay out the riser so that the seams would line up.
![]() ordered 1 stick of 6x2x0.25, came in 24ft mill stock. i never actually measured it, but we're good, i only had 1" left over!! damn thing is that 1" cost me $1 ![]() ![]() putting a full round on 4" c-channel is kind of a b!tch, but i think the effect was worth the effort. it's for the body mounts, so that cut will be hanging out on it's own. i also hate grinding this much, but without a huge drop-arm band saw i wasn't getting the cut precision in the 6x2. the ceiling mounted air filter was a HUGE win. ![]() ![]() ![]() ![]() ![]() |

Lining the seams up, next level detail...super nice!
Cool sweatshirt, bro...see you there in February?
