    Bumper Tuck Custom Shock

    I want to tuck the bumpers on my 88, but i'd prefer not to drill holes in the stock bumper shock. I fabricated a custom "shock" that's really just a solid bracket to hold the bumper, but the last step is to set how far out the tube that houses the bolt for the bumper is (which will determine the final amount of tucked-ness of the bumper) if that all makes sense.

    My question is, and i have searched, i can't find the answer, how far out should i put it? I've looked at pictures in the tech article and it's basically flush with the end of the body of the shock, (http://r3vlimited.com/tech/tuck/shocks.jpg) but i didn't know if anyone has done this and therefore had some better numbers (can't see under the bumper to measure) to get the maximum tuck. Any maybe someone knows if this is already the most tuck you can acheive...

    IF i did it right, i've attached a very detailed, highly descriptive painting that leonardo da vinci created for me to explain my goal. Find an x value that gives the most tuck but still works.

    This is why google said "sorry no responce"

    if your just gonna have solid brackets holding on the bumper then why have the bumper? its now just a big piece of metal sticking out from the car.

    what you really wanna do is to mount the shocks further into the car. that way the bumper is tucked and you still retain the shocks absorbing capabilities. that's my 2 cents

      Search Ebay there are people that have built the bracket you describe.

        these are my front shocks fully compressed if that helps. might be taking off the bumper soon so i might be able to measure for you.

            Nice thing about drilling your shocks is...if you bump something while driving, your bumper will pop outwards on the other side (extended shock length) and not damage the bumper as much as if it were solidly mounted (your intention). Trust me, I have bumped a couple things with mine...and I just kick it back to where it should be, no harm, no foul

              Thanks CW, do you like the look of it? I figured i'd end up just going to the lenght of a drilled shock anyway but thought it was worth a shot asking.

              Yeah if it's no big deal i'd appreciate a measurement, obviously i'd measure my own but they're still full length.

                First I will say that I agree with custom Jim that sectioning the bumper along with tucking them is the best way to go. Unfortunatlly that goes beyond my skills. The way I did mine is not the best way, but it was easy and required little work.



                I did this about 9 years ago so some of what I did is a little fuzzy, but basically what I did was collapse the bumper shocks by drilling a hole in them to release the pressure, then remounted the bumper shocks back on the frame about two inches toward the rear of the car. This will require you to drill a couple new holes in the frame for the new location of the bumper shocks.

                The stock bumper filler is discarded, and the chrome trim under the grille becomes the new bumper filler. I would have trimed the rubber corner fillers that mount under the fender extensions to fit, but mine were wasted.

                A better way to go would be to fabricate some new, lighter bumper brackets, but I do not possess those skills. I did however cut away most of the inner shell of the bumper to save weight.

                I can also attest to the durability of the new set up. With out going into to much detail, the front of my 05 Silverado got acquainted with the front of the 74 in the driveway over the winter with these results...


                I destroyed the grille, but the bumper didn't move.

                  I feel like if you solidly mount the bumper to the car, a small fender vendetta could in fact crease some body panels. At least with the stock drilled shocks, they will compress a bit and as stated before if it was hit on one side, the bumper will pivot

                    I'm not gonna waste everyone's times dudes, if there's nobody that's got the measurement it's cool, but you guys don't have to waste your time, i've already made em and shit, it's just to mess around. everyone's lecturing on how they'd do it but here's the thing since i dind't scrub my stock shocks i can put it back normal anytime i want lol it was just a little rainy day fab project and i just used the drilled shock length and it worked fine.

                    i'd post a pic of it but i'm guessing nobody cares hahah

                    btw tilina your chevy is killer man. i drive a 64 pontiac, got a lotta love for the old muscle cars

                      Why not just measure the length of the stock shock, then measure the shaft length that sticks out and figure out how long a fully compressed shock would be.

                      Stock shock - shock shaft length = compressed length.

                          IMO, you cant go maximum tuck...if i tuck my bumpers in completely they look stupid because theres a 1" gap now between the rubber surround and the bumper, you need to leave them out just a bit.
