also doing a 3.4 swap. rebuilding motor in process.

gonna use HD 4inch Trail gear springs with 6inch shackles.

gonna be running 39.5+

i want some ideas on springs and what you think i should use maybe even. ill be starting this next weekend on cleaning up axles i just rebuild them with 513 gears lockers F/R

 

im running 5inch tg front and rear springs and have enough clearence for 39s you made a good choice with 513s shave the 14bolt and chromoly the front axle but eventually the d44 will be your week link if you run 39s

 

the 44 isnt to bad with the 39.5's ive ran the hell out of my friends dana 44 and havent had a problem.

but yeah idk if i should do 4inch in front and 5inch in rear or not with a 4runner im debating still because of the sag but if i go hd i dont think they get sag at all. i wanna do 4inch F/R because i have a 2inch body i put on for the 3.4.

 

im debating on buying this as a full kit.

Trail gear shock hoops.
4inch HD springs f/r
6inch drop shackles
creeper joint shackle mounts.
high steer from sky manufacturing.

i think thats all i need in my head atleast

 

I'm in the middle of the same thing...what did you wind up going with?
