    Default Coil Sprung Series

    Hi guys,
    I'm doing a 1966 2a 88' pickup. frame up restoration and i am making it coil sprung, i just bought the axles and i pulled them off of a classic(a late one) and got the springs too. i was wondering if you guys had any info on tips and pointers for this build.

    P.S if any of you want to show me somthing i will be at forrests rally in november and i live down the road so you can talk to me then too.

    Thanks,
    -Ethan

    Couple of thoughts, questions, whatever you wanna call 'em.....

    A) Did you swap over to a Designa chassis, where you have a Series chassis that's modified for being a coil-sprung suspension; or are you keeping the original chassis then altering it for the suspension; OR, have you switched to a coil-sprung chassis, then modified it to fit the Series body to it?

    B) Since you're using axles off of a coil-sprung vehicle (an RRC?), you'll have 3.54 diffs then, instead of the 4.7's (unless you swap them back in). What engine are you going to be using? Do you need to go back to the 4.7's to have it usable on the road w/ a 4-banger, or are you going to have something else that can make good use of the 3.54s on the highway?

    That's a start.......

    I am going to switch back to the series diffs im using the axles off a RRC and im using the standared 2.25 rover engine and tranni and i want to swap it over to a designa chassis i dont want to have the headache of modifying the RRC or the series frame.
    what do ya think

    Ok.... Designa chassis gets you the coiler axles w/ the Series body without having to fabricate, the 4.7 diffs will keep the 2.25 usable......

    Is your end-result goal to have a vehicle that's a more-comfortable vehicle that can be a daily driver, or, are you wanting to have something that's improved/competitive for serious offroad use?

    What size wheels/tires are you planning? If you're staying around the 7.5x16 or 235/85R16 size, not a deal, but if you're wanting to go larger, you might consider stronger diffs and axles.

    Im going to use the Designa chassis with RRC axles 32' tire probablly and a more comfotable daily driver for sure but finding that even balance between great off roading and a daliy driver will be the key. disc brakes is abig thing too, comfort like you said and of corse good off roading and flex.. stronger diffs would be good but they wont increse my road speed will they? and besides i really cant go that fast with a 2.25 any way.

    If you were going for more of a hard-core off-roader, I'd have really suggested stronger diffs and possibly a locking diff, but the locking isn't as important for a daily driver.

    I did have a thought..... your 4.7's are probably 10-spline, whereas the axles in the coiler axles are 24-spline.... something's gonna have to change, FWIW..... (use the 4.7 gears, but converted over for the 24-splines?)

    So, you may still want to consider upgrading axles, at least. (the 10-spline are known to simply pop, even backing out of the driveway, even w/ the 2.25 engine.....)

    235/85R16 is about a 32" tire, so you should be fine w/ them. AT or MT?

    ethan I could help you change the coiler chassis to fit the series, the designa or whatever chassis are expensive aren't they? you could always do the 24 splines later. I figure holland sold you 10 spline, but im not sure. stop up to my house this weekend, sat morning I am working on the madison guy's 109 pick up. so come check it out.

    Sounds like you've got some great help nearby!



    Didn't think about, but yes, earlier RRCs could have 10-spline, that would solve the 10/24 spline compatibility issue, if the ones in-hand are also 10 spline.


    I have to agree, Designa chassis aren't cheap. Would be a clean way to swap over, though, w/o fab work, but, yeah, it'd be pricey. The original frame can have the coil mounts welded on, though, would be a lot cheaper...... FWIW.....

    leslie,
    I think that i may buy a 94" RRC ( the one that i was going to pull the axles off of in the first place.) its not going to be expensive 200$ and i get a whole truck! I figured i would shorten the frame it is going to be the same shape after i shorten it to 88' right? and then the only things that i will have to modefy are the engine & tranny mounts ( the engine is shot in the one i might buy) and some mounts for the tub, seat box and firewall right/
    Thanks

    That'd work; yup, I've seen RRC's turned into "Defenders" before...... relocated the motor mounts, add the outriggers for the bulkhead and gastank...... oh, and a rear crossmember, too.....
