63's rear / 57's front ****New pics 56k beware****

[shaun]

Well the swap is done. I have 57's in the fron with an 80* to 90* shackle angle and the rear has a 65* shackle angle. 7" eye to eye shackles up front (DIY4X great product), stock rear 88-98 shackles. The rear mount is all the way at the rear of the frame did not touch the front mount for the rear springs. Front mount for front springs is swapped side to side (this was a pain in the a$$ b/c my truck had apparently been in an accident and we had to straighten the frame on the passenger side to make the brackets work) the rear hanger for the front springs was not touched. I need to brace the front and rear of my frame and we will see from there. I am going to flex it today and I will post pics tommorrow.

How much did it move your axles?

 

[Bhintz]

pics would be nice

Tease

Did you do this on a truck or a K5? Did you relocate the gas tank if a K5?

That's like 10" more wheelbase, wow.

 

[shaun]

This is on a k5. I moved the gas tank into the bed. I believe it is 7" in the rear (52's to 63's w/o moving front perch moves axle back 5.5 inches and zero rates move it back another 1.5" which = 7) The front is moved foward by the zero rates which is 1.5" plus the long side of the 57's. How long are stock front springs on a 90 Jimmy? How offset are fords again. I figure it is somewhere near 12 - 14 inches.

Like I said in my original post. Pics will be tommorrow maybe. It has rained all day and I dont have the wipers wired yet so might not be able to drive it but I will try. Pics should be tommorrow. Any other questions just ask.

 

[shaun]

Here are the pics I promised. We got poser pics. Some light one wheel drive pics (open in the rear w/ no front driveline) And some how the f did this happen to my springs. Lots o pics sorry

Poser

57's shackle angle

Smooth belly (need front driveline)

 

[shaun]

One wheel drivin

Damn Brakelines

Next spot

Freakin brakelines and shocks. MOre changes to come

What happened to the spring (we fixed it the damn clamp broke)

 

[CyberSniper]

Wow... so many questions.

What is the center pin measurement of the leaf springs? I noticed your front axle is moved a lot further forward than my 56s. My front axle went 4.5" forward. I still have about 9" of front overhang in front of my 40s.

What does your pinion do as those springs drop? My 56s quickly finds the limit of the 1310 pinion yoke.

What are you going to do for bump stops in the rear?

 

[shaun]

I dont know the center pin measurement of 57's. I believe it is 25" in front and 32" in back plus the 0 rate pushing another 1.5" foward. Havent figured out bumpstops front or rear yet. That is coming. Along with center drop front brakelines or much longer front lines and a longer shock (even though these are rancho 5012's (which are the longest they offer 13.25 " travel and mine are set up 8" of drop and 5.25" of stuff.) I havent hooked up the front driveline so dont know how the pinion will act. I am going to put in 7* shims to clock the yoke up though b/c right now it sits perfectly level to the ground.

OMG, even after fixing the clamps it looks like you will eventually break the main leaf ahead of the axle. It appears to be too thin and long to stand up to a full size front application.

 

[boz42]

that is sweeeeeeet.

I second that idea.

 

[shaun]

Actually if I was to break the main leaf before the axle being that is the long side not the part in front of the axle. I am not saying you are wrong but until it happens I will disagree. I have only had this done 2 weeks now. And I have thouroughly beat the truck in that time. I had to do this to test it. So far the only issue was the broken clamp (since fixed.) I will let you guys know what happens but I will continue to hope you are wrong. And if it happens I will swap 3" wide 57's in there place

 

[smokkey1]

I'm curios how long are those brake lines now? Looks awesome

 

[shaun]

They are 26" long. I am either going to do center drop brakes like the rear or am going to run a set of 34" long brakelines from coleman racing.

 

[CyberSniper]

I bought some OE brake hose extensions. They add 12" of length. I paid $20/each for them. So, now my brake hoses are like three feet long.

 

[shaun]

where did you get those?. The new brakelines are only about 24.oo each so I will probably get them but still curious.

 

[CyberSniper]

At the auto parts store... when I get home I'll look up the part numbers.


PS: since I'm going to run it on the street I need DOT approved brake hoses.

 

[shaun]

Mine is run on the street. Coleman racing is dot approved (i thought I will double check)
