I am new to this and I just got my 84 K20 6.2 liter diesel. I am curious to know how hard it is to put a lift on a truck and which lift to get. Thanks to all for your help.
-
putting on a lift is pretty involved, how much mechanical work have you done?
-
well I have played around with my power windows and power steering but I have not attempted anything on this scale before. thats why I am asking to see if I am in over my head on this one.
-
Not to say you cant do it but get a buddy to help that has done some work but either way your going to have to remove the spring bolts and u bolts they might have to be cut off, had to cut all mine off the steering arm has to be changed there are a couple ways to do it. you have to pick which one to use brake lines have to be changed. Shocks also. What size tire you plane on using? And what do you plan on doing with it?
-
I planned on doing it with a friend of mine who has done this dozens of times so I can learn. I am thinking about 35" all-terrains so I can go trail riding and camping with my buddies on the weekends.
-
If that is the case, you should be fine with someone with hands on...
-
4" with 35's you need to trim the fenders if you want 35s 6" will do with maybe a little fender trimming
-
Sounds like you have done this a few times. Thanks for the wisdom.
-
no problem

fender trimin is depitced on how much/little backspace/offset you are running.. other words how far out you plan stickign the tire out...
this is a 35x1250 or 315/75/16 ona 16x7" rim with 5.125" of back spacing

thats not true about having to trim fenders im running 35/12.50/15 on a stock lift truck 1984 k10 swb 4x4 from canada. and nothing rubs granted tires only have 14 tread left and are very close but they do fit just eat up front end components so i suggest beefing those up
-
If you are running 35's and didn't trim anything, the truck has a lift on it.
-
like chris said you have at least a 6" lift
-

then please explain my pictures?????
-
Certainly no lift in the pics! Although I see you have the 3/4 ton 3 leafs that gives about an inch or so. I personally feel those charts are pretty worthless. It's all how you use your truck. I buddy of mine had a street only truck and would drive around with stock ride height and 35's too. He couldn't turn the wheel wheel to half lock on even pavement without some serious rubbing...but he did it! On the flipside there are people out there with 6" and 33's because they twist up real good. I ran 35's and 4" with very very minimal fender triming. It was fine for mud and street.

Easy....those tires probable only measure out to an actual 32 or 33".
They have no tread, and tires are measured (by the manufacturer) with no vehicle weight on them and max psi.
-
most time that i see rubbing its on the frame and that has to due with the rims backspacing and width also tire width. also about the chart if you read the second line it tells you its not guarantied but just give a picture

do you even know what your talking about?????????
pro comp extreme AT 315.75/16
new they are 34.6" OD
in that picture they are 33.75
how many LT tires are actually the same size they are specd on the sidewall????? answer NONE!!!
even with the 25% tread left... i have 2+" at any tight spot which in essence defeat the "worn/bald" tire..
-
calm down buddy. i think he said they were probably 32-33 and your saying they are 33.75 i don't see that much of a difference there and he also said they ain't the same size as spec'd and so did you so i think your agreeing with him, all is done
-
No, there are no tires that actually spec out to what they say on the sidewall. Anyone in the 4x world knows that.
Seeing as procomp has them listed at 34.6", that is mounted with max psi inflation. Once you put them on the vehicle and rest the vehicles weight on them, they usually squat about 3/4-1". Add to the fact that you are saying they are at 25% tread would make them approx 5/32", so on a full diameter that is 15/32's off top and bottom, making it almost another inch. So 2" off of 34.6" = 32.6"....approx. But that is splitting hairs.
Also with you being a 3/4 ton you sit an inch higher, so on a half ton it would be equivalent to running a 31.5/32" tire which is easily done on a stock truck.
You could always park on a hard flat surface, get a level and tape out, measure it and take a pic if you feel the need to prove me wrong. ;)

i dont need to ;D
between you and cap... said my truck had to be lifted for said tires..... to fit without cutting/bending sheet metal
;)

1) I HIGHLY suggest you calm down.
2) Normal driving on a flat road you won't rub, take it in the woods and get it off camber and you will start rubbing.
3) 315x75x16 tires are NOT 12.50 at the tread, they are 12.50 at the sidewall, more like 10-11" at the tread and they are not like "35's". When most offroad people are talking about 35's they mean 35x14.50, which will rub even on your truck
4) I didn't pay attention to your pictures, and didn't realize yours was a 3/4T truck, which will not have the same issues as a 1/2T as they sit a little higher, but reread #2.
5)There is absolutely NO reason for you to get hostile on the board.
6)swearing is NOT allowed on the board in ANY manner, which by default gets you a 5 day ban.

In those pix you do not show us the whole view of the front and rear spring.
Generally 3/4 ton suspensions will require at minimum add a leafs and or blocks to clear 33"s and look decent. 35"s may rub depending on wheel offset and how you are driving.
For a half ton you'll need a 4" lift to clear 35"s
-
not sure im following what you are getting at V
there is a full side shot
front to rear with tire full lock to left
rear to front with trie full lock to right
last two show the front and rear of said front right spring
currently dont have any 315/75/16 to put back on the truck for mock-up
this is 285/75/16 cooper ATR tires on 16x7 rims or 33" tires with no rubbing with AFAIK stock 3 leaf spring pack up front back of the trailer is ~30"

Look at that frame flex! ;)

Just have fun. I don't even go on pirate or any other form just cause on here you get what you need. If your wrong or if someone thinks you are you are told not draged out in the street and tarred and featherd. Forgive my spelling due to no spell check and this phone
i do have fun.. if i got a problem i take it to PM with said memeber.
yes pirate is good they will laugh at you for 4" and 35" tires.. alot are running 4" and 40"+ tires and yes trimmed with a sawzaw
posted attacthment is a 4" lift(52/64swap) with 35s or 37" tires cant rember excatly..
-
Too bad he didn't have an rti.....that pic is a bad illusion. Look at the front axle compared to the bumper, he is hardly stuffing the front. Lots of rear axle droop though.
-
i dont think you need 6 in lift for 35 either. mine is 4 inche spring front lift with blocks in the rear. no fender trimming and i am using 35x12.5x15 bfg all terrain. tires have about 85-90 percent tread lift. 1/2 ton truck. there is a pretty good gap and truck doesn't rub. then again i dont get too crazy off roading either just my 2 cents

Nice truck. But if you do any decent stuff off road, you may find your tires will modify the body for you. ;D
-
yea i'll be the first to admit i dont off road it hard core at all.
