4" Leaf spring vs 4" shackle flip

[RoryH19]

Pro and cons?

 

[Arkansas_V8]

More flex with the shackle flip. Axle moves forward 1/2 inch with ORD flip.

Springs are just springs. Ride rough, flex okay.

If your rear springs are in good shape, do the shackle flip. Use they're offset plates to move it back.

Unless you wanna do zero rates front and rear for a total of 5" lift.

Thanks.
I'm leaning toward spring but keep reading good reviews on the flip.
Also want my axle to stay centered. Didn't know the flip would move it forward.

Unless you off road a lot, spring is great.


Those axle offset plates are so thin, you could re-center after flip, and it wont give a big rake.

The flip causes the axle to move forward because you are not changing the front pivot point of the spring, only the rear. I'd go with the springs since they're less work.

I had 6" Skyjacker all spring lift on a K5 back in the early 90's. Rode great, but I think my 36" radials made it a little bouncy due to sidewall flex (load range C). I towed my 18' car trailer with a '68 El Camino on it without issues (5000-5500 LBS).

I remember the good old days. Huge lifts, big tires.

Now its smallest lift with biggest tires.

All spring it is.
Going with tuff country EZ lift. 3" front and 4" rear to level out the k5.
Have a 3" lift now; spring/block with the rear lower.

And recip saws... ... fir the fendas..

The less arch a spring has the better it flexes. So a spring lift with addition arch built in for lift will be a stiffer less flexy spring. Depending what you use your truck for this could be just fine.

Before rock hoppers there were rock crawlers... old trucks with 4" lift springs, long shocks, big tires and modified body work. They actually work really awesome.

Just need it to be multi purpose.
Not rock crawling or driving F1 with it.
Dirt, mud, trails, highway, monster sized pot holes in DFW and maybe snow if I go north in the winter.

At that time it was huge lifts, and huge tires here in the south, mud bogging was king.


I know they work well. It is what I built. Times are coming back around.

Then all you need is Springs.

Yeah for sure I get that... just bringing up this up for sake of it.
But I still think you need a BB!
