    K30's are about as diverse as K10's, they could have come with any number of engine, tranny and t-case combos based on how it was ordered or what year model it is.

    While the vast majority did have 14 bolts rear axles, if the truck is a dually it would have a D70HD (unless it was a cab-chassis which could be either axle depending on how it was ordered). If I'm not mistaken all crew cabs built from 80 to 91 should have had a 205 t-case.

    I think an easier approach to this might be to know if you had a particular truck or combo of parts that you are looking for (or at).

    ok, heres the deal!!!

    a friend of mine knows where theres a k30 crew cab for sale. he beleives its a 83. thats about all he knows right now. he is getting the phone number for me tonight, so i will find out more tomarrow. it is a single tire rear (not dually).

    the main components im curious about is the axles and the motor. whats the chances that this thing is a 454/400/205/d60/14bff for $3000?.....lol.

    ill try to keep you all informed on this find. hopefully my friend knows what he was talking about. if so that baby will take up about 21-22 feet of my 70 foot driveway.......lol.
    if i get this it will be about 14" lift with 44's. /forums/images/graemlins/thumb.gif SWEET!!!!

    [/ QUOTE ]
    Yes, all K30's come with the D60 front, but the rear axle can be either the 14FF in SRW and DRW, plus the D70 in the dually rear.
    Not all had 454's. Probably about 65% had them. The other percentage had 350's, 6.2L's, inline 6's (yep!), and older ones had 400's.
    454's and 6.2L's were the most popular engines for these trucks.

    ok........if it is an 83 like my friend belives it is, what is the most common setup as far as engine, tranny, t-case?

    he knows it is a single rear wheel crew cab, so that makes it a 14bff. what was GM thinking when they put a 6cyl. in a k30's? whats the most likely gears for it to be? 4.10's?

    my friend said the body is in pretty decent shape, so what do you think the truck would be worth?

    thats all for now wes.......answer away!!!!

    If the '83 is gas, and an automatic, it will have the 454 or 350, with me leaning towards the 454 more than the 350. Tranny will be the 400 with a 205 t-case. Gear ratio should be 4.10 on the higher average.

    GM made these trucks available with I-6's for those who felt like they didn't need the power and gas robbing BBC's. The ratio of the axles with the I-6 motors were normally 4.56 gears. /forums/images/graemlins/thumb.gif

    For an '83 and pretty decent shape, and if everything ran good with no major mechanical problems, I would say on average, $3000 for it. This is for a bone stock K30. If you start to look at the Silverado trim, expect the price to go up some more, say around up to $1000 more, but not over. Get up to newer years, the price will definitely go up.

    ok, i finally saw it today. it is a 1980 GMC k30. the emblem says its a 35. is that GMC's version of the k30? or does it signafiy something different?

    it has a d60/14b/350/465/205. it has a 1997 350 in it. runs ok as far as i could tell. interior isnt great, but everything is there. has tilt wheel and a/c also. the body isnt bad, just dirty.

    he is asking $3000 for it, but said he will take $2000.
    does anyone see any reason why this wouldnt be worth it?
    i dont know how much d60's are in everyone elses neck of the woods, but here they run $1000-$1500, so i cant see the bad in this deal. can anyone else? TIA!!!

    35 is just GMC's way of labeling trucks, they used 15, 25, 35 and Chevy used 10, 20, 30.

    The only thing that would be different about that truck is that the original inner axles on the D60 will neck down in the middle 3/4 of the shaft but the ends are 1.5" with 35 splines at the carrier. The neat part (if they're still there) is that the 80 model should have originally had Spicer locking hubs, they're a little finicky to work but real strong.

    Don't forget to check the frame behind the steering box for cracks, it's easy to fix but great for bargaining leverage. Also check the engine crossmember right under the fuel pump, this is also prone to cracking.

    Yep, that's a GMC.

    The drivetrain combo sounds good, too. Nothing wrong with a 350 or 465. I would jump on this truck if the owner will take the $2000 price. That's pretty good and cheap especially if everything is running and good. /forums/images/graemlins/thumb.gif

    ok, i think im going to buy the k35....so....now the good questions!!!

    im thinking about going with 44's on it. what size lift would you guys suggest in order to clear? i will problably get some bushwacker fender flares for it also, so that will help some. are the lifts for the k35 the same as the k25's?

    anyone have any pics of any crew cabs lifted?

    the setup that i was thinking is maybe a 14" lift with 44's and maybe replace the 465 with a 400. disks in the rear. possibly a 89-91 front end swap. paint it all white with black rock crawler rims and black accesories.

    any comments or pics are greatly appreciated. thanks.

    the only lift close to 14 inch would be superlift's 12 inch unless you go with custom spring packs, the one ton should have 56 inch rear springs, not the 52's which are more common on the 1/2 and 3/4 ton.

    to get 14 inches, in the front go with the 12 inch springs, 1 inch zero-rate and 1 inch shackle, in the rear the tallest springs are 8 inchers from superlift or skyjacker, again unless you go custom, do these, with a shackle flip, and 2 inch block and there you will have 14 inches

    also, if you are going to do bushwacker cut outs, you may not need this much lift, especially if you are combining with a body lift

    but should look good /forums/images/graemlins/thumb.gif
    good luck and have some pics of this /forums/images/graemlins/pimp1.gif

    Sounds good with the 44" plan. But...../forums/images/graemlins/frown.gif

    The 465 tranny does not allow long enough of a front driveshaft to operate at a satisfactory angle for these trucks when they are lifted higher. These 465/205 setups use the shortest front driveshafts of ALL GM trucks, regardless of the tranny/t-case combo. /forums/images/graemlins/frown.gif

    Like you were saying, about swapping the 400 in place of the 465, that would be a wise decision, especially for this amount of lift. The only other option if you wanted to retain the 465/205 would be to employ High Angle driveshafts and their 1350 CV joints. /forums/images/graemlins/thumb.gif

    Yep, in order to use the 8" Superlift rear springs on a K30, the shackle hangers need to be relocated 4" forward of their mounting holes.
    And yes, I would recommend the ORD shackle flip for this extra lift so the 4" block would be eliminated.
    Keep in mind when ordering the shackle flip that you need to tell ORD that it will fit a K30 instead of a K5, 10, 20. The flip brackets for the K30 will be the correct narrow ones. /forums/images/graemlins/thumb.gif
