    Default Tubular Upper/Lower Arms & Coilovers

    Short version: I am curious to see what offers I would get if I were to sell these tubular upper and lower control arms and QA1 coil overs. I disassembled this stuff and got it all cleaned up. I have added grease fittings to the upper control arm bushings, but haven't done the lowers yet (not sure how much of a PITA it will be to get the lower bushings out). One upper arm weighs 7lbs and one lower arm weighs 10lbs. I will weigh a coil over tomorrow after I get them cleaned up as well.


    Long version: As most of you know, I ended up with the tubular control arms that were on Scott Q-Dbag's truck way back in the day. His truck was a 2000, so it had the curved upper pivot shaft on the passenger side. Since mine is a 1999, I need that pivot shaft to be straight. I obtained a straight pivot shaft, and completely disassembled both upper arms. I only needed to swap the passenger side, but I wanted a fresh coat of paint on both so they would match. I took the time to machine the upper bushings and drill/tap the arms to allow for grease fittings. I just put the upper arms back together tonight, but I'm still debating whether I want to use them or not. I contacted Dan Arcand probably 7-8 months ago about these arms, and he said he wouldn't recommend them for street use. They "appear" just fine to me, and they even have mounts for the factory sway bar. If they weren't meant for any street use, why would they have those mounts in the first place?

    Here are some details from back in the GSM days:

    70lb lighter than stock
    2" lower than stock
    Heavy duty ball joints
    Black poly urethane bushings
    All chromoly construction
    Bump stop and sway bar mount for direct stock replacement
    Extremely smooth a-arm movement vs. stock binding rubber
    2" more shock travel than stock
    Adjustable ride and spring with QA-1 coil overs

    Initial pricing will be $1,699.00 using the modified factory spindle

    That was all taken from notes from back in the day. I am just curious what interest there is for these, especially from the few hardcore drag racers here. The "advertised" weight reduction of 70lb is not confirmed by me yet.

    Weights
    Uppers: 7lb ea
    Lowers: 10lb ea
    Coilovers: 9lb ea
    That means these parts weigh 26lbs per side, 52lbs total

    Feel free to PM me if you would rather not make your offer public.

    Pictures...the first couple are from the early 2000s when these were first made and test-fitted. The handful after those are as-is off Scott's truck after it had sat for ~12-13 years outside. They have bascially zero miles on them, as you can tell from the rotors. The pictures in post #2 are since they've been in my possession.

    Wow, those are nice. I wish I could say yes but I'm in the middle of a big project. Would love to see this happen.

    If I didn't already spend my limit on DJM's and 408kotaRT uppers I would definitely give you want they are worth. Who knows? I might be sending you a PM in the near future if no one else bites. I can't believe these aren't scooped....Everyone wants to wait until the seller is at his bottom before jumping, but keep in mind people these CA's are extremely hard to get. If these were for sale a year ago I would have taken a completely different direction with my front suspension......GLWS and I hope the next buyer appreciates what they are getting

    They actuslly were for sale a year ago...that's about when I got them.

    The reason they aren't gone get is because I'm not sure I want to part ways with them. I've had a lot of offers...but I don't even have a figure in my head that would make me let them go. I made this feeler just to see what I could possibly get out of them.

    Do you know what ball joint that is? Do the part numbers change for the ball joint through the years?

    Also, do you have the part number for the coilover?

    I damn sure wouldn't take any low-ball offer. No matter how long it takes to sell.

    The lower ball joint is a Moog #K727 style. Don't have a part number for the uppers without taking them back apart.

    Unsure on part number for the coilover.

    Thanks. I have a decent offer right now but it still hasn't swayed me enough to let them go just yet. I just have that feeling that I'd be kicking myself in the butt down the road for letting them go.

    Dave, the ball joints look like late 60s early 70s threaded ball joints. B or E body? Just a guess and I don't have part #s yet.

    That works, thanks. K727 is all I needed. But I think the lower ones changed in 2000-2004 to a 10 degree where these are a 7 degree taper. I am getting specs from Moog. So that mean unless someone changed those lower ball joints to newer style they wont work on the 2000 to 2004 trucks. Andrew you fit them on your truck already? Curious is this is true or not. It would make sense.

    Taper

    .840 large end

    .714 small end

    2” per foot

    No, but that would be good to know. I don't recall the spindle changing, but I haven't compared spindle part numbers on RockAuto to know for sure. I know the outter tie rod end changed, but I couldn't find the exact specs to compare to my 1999.

    It would be interesting to hear what Moog says on the difference.

    David,

    I haven't put them on yet, but I'll be using the 2000 spindles that came with all of this.

    That is interesting that you are using 2000 spindles. Maybe the spindles themselves were reamed out to accommodate the older ball joints. I have to see if that is even possible. You can only go one way before you have to stick to that. Either 10 to 7 to 7 to 10.

    So yea, The K727 is a larger hole so you can go from a 10 degree to a 7 with no problem.

    It would go from

    Small: .714 to .76

    Large: .84 to .89

    So that is probably why that spindle is modified to those control arms.

    I should put a mic on ball joints and spindle to see. Afterall, this is a Scott Q product, so there's no certainty that it's all good to go. Lol

    And, I'm assuming these are 2000 spindles. I'm pretty sure that's around the time these were made. I know for sure they aren't 03+.

    Yea, let me know what you find out. I am just going to have my own build, hence looking for better ball joints.

    How many times did ball joints/spindles change throughout the years?

    From the research I did, the ball joints were 97-99 and 00-04.

    The spindles are probably the same.

    However, the Lower control arms are the same part number regardless of year, that is what throws me off.
