    Many people try to find a shock set-up that allows a longer travel shock. The most popular option is the 45* Inboard shock option. I did not want to loose any shock dampening, as I am running the ultra soft Springer Suspension I felt I needed something to help stabilize the rig, as it still has to make it to the trail without a trailer.

    After a lot of head scratching I decided to mount the shocks through the bed. Greg (a.k.a. Greg72) offered to fab my idea and weld it all in. I offered to be the Tool Go-fer and it was settled. Here is a brief overview of how we (Greg) did it.

    Here is your run of the mill 73-91 K5 bed:

    Here is your run of the mill 73-91 K5 bed with a 15” x 10” hole cut out of it:

    [​IMG]

    The hardest part of cutting the bed was the bracing underneath it all. Also, be careful of the body mount, Greg cut right up to it.

    Below is version 2.0 of the spring plate mounts. We decided that squeezing the shock between the drums and the springs would be too difficult and leave the piston in a vulnerable spot. So we then put it on the outside edge of the spring plate. It is angled as to not put any pre-load on the shock. The top mounts on the hoop itself are angled also.

    [​IMG]

    Next we had to bend the tube (1.5” tube). I put my more than adequate girth behind the bar. How do you know you are in a fabrication shop in Silicon Valley? The Tool Go-fer is yapping on a cell fone while bending tube, that’s how.

    [​IMG]

    (Please note the CAINTMAKIT! Shirt, zakk’s M.O.)

    So now the hoop was gussetted with 3/16” Plate and up-hand welded, all fab work done by Uber-Dooper-Super-Swamper-Fabricator Greg

    [​IMG]

    Greg then welded the hoops to the frame and bolted it all up. After a few “Jump in the bed to see if it breaks” tests, it was deemed necessary to place a bar between the hoops to keep them from flexing. Truck Flex = Good Shock Hoop Flex = Bad

    So here is the final product:

    [​IMG]

    and a close up of one hoop:

    Overall, the rear suspension is much more stable while driving, even without the Springer Track Bar. I am going to do further testing, but preliminary finds show that the 95% available dampening of the shocks, which are RS99036’s set at “9”, dampen the bumps and potholes fine, even at freeway speeds and in turns. All that is left is to paint the center bar.

    I would like to thank Greg (Greg72) for all of his awesome fabrication work. He did a great job making this set-up work. The end result is a very professional looking and very FUNCTIONAL modification that I am very pleased with.

    i am going to fab something like what ORD did to cover theirs. weld some of the metal back in, and then pastic boots over the shocks.

    That isn't my shop, that's Greg's! He has a full service Fab Shop in his backyard! It must been seen to be believed!

    A. That "shop" is WAY too neat and clean. /forums/images/graemlins/shocked.gif

    B. I dig the old oscilloscope on the lower shelf. It's been a long time since I saw one with a round CRT. /forums/images/graemlins/thumb.gif

    C. The shock mounts look way too cool! /forums/images/graemlins/pimp1.gif

    Looks awsome guys!! Are you still planning on tubbing the rear wells Zakk? with all the flex from Marv's set-up and no shock limitations you'll be scrubbing those fenderwells easily!

    i am going to gut the e-brake first. I have a 28" steel braided extended brakeline that needs to go in, then flex it real good. I want to see what rubs and go from there. I am going to have to do something...just going to wait to see what.

    What kind of tube, DOM, HREW? And what is the wall, .120? One last question, those shocks can run in that position, seems they might be upside down but I have no knowledge on them.

    Outstanding piece of fab. /forums/images/graemlins/thumb.gif

    HREW 1.5" Tube .120" Wall

    Rancho 9000 shocks can be run upside down. It was done that was so that Rita can get back to them and adjust them as needed.

    absolutely beautiful, nice work guys
    i love to see good solid backyard fabbing, i've seen too many hack jobs (i'm guilty too)...
    good luck with the setup
