Stupid question but how much modification would I have to do to mount the 3 in rear leaf springs onto my 86 t4r? Do I have to adjust the shackles at all?

How much should a shop fairly charge to install all-pro springs in front and back? I don't have access to a shop nor a welder. I too am interested in replacing my springs with these.

Crash is absolutely right. Are the Allpro springs your looking at new or used. I don't see a 3 inch spring on allpro's website. But their springs are 56 inches compared to 47.5 stock springs. its not to hard but welding the front passangers hanger can be a challence since you should technically drop the gas tank before welding right next to it.

the kit cost 750 and a good shop should not charge you more than 10 hours to install this kit IMHO and that is with dropping the gas tank. but I would bet most will ask 15+

Yeah the springs are used. I found them on craigslist for 35 bucks! The guy I bought them from said I can use the stock mounts. I haven't had time to actually check yet so I'm not really sure, but I couldn't pass up on the deal!
 
I got a quote from a local shop today for $900 to install the entire extreme lift kit from all-pro. I'd still love to hear from anyone on whether or not I need to worry about drive shaft re-work with 4" of lift.
 
At 4" you might be looking at needing a longer driveshaft, caster wedges to correct the pinion angle, and maybe a CV joint at the transfer case. You'll almost certainly need to extend the brake line. And that's just the rear. Are you IFS or solid axle? If you're solid axle in the front you'll need brake lines, drag link correcting or crossover steering, and the same driveshaft work. If you're driving on the street you'll probably want to correct your caster, and you shouldn't use caster wedges in front, which means cutting and turning the knuckles.

Lifting 4 inches requires a lot of other things along with it, it's not as easy as slapping a set of springs under the truck and driving off.

I have an 85 4runner so I'm FSA. I currently have 4 inch of lift with shitty pro-comp springs. I have extended brake lines and they did a 2* shim to fix the pinion angle. This was all done when the prior owner owned the truck. I simply have the receipts from when it was done. The extreme lift kit from all-pro includes hysteer components.

^ That's a pretty comprehensive kit. You'll probably need longer driveshafts front and rear, and you might need longer slip joints to accomodate the greater travel. You might need a CV joint on the tcase side of the rear driveshaft, and you might need mods to your front axle to correct the caster, or you might not, depending on how the kit is set up and how much street driving you plan on doing.

I sure wish someone who has done a 4" lift could chime in and add some certainty to this topic. I need to know so I know what I do or do not have to purchase. My instinct tells me that if I currently have 4 inches of lift without drive-shaft vibration or any problem of that sort then there should be no difference with the All-Pro...
 
So I called All-Pro up which is probably what I should have done in the first place. Talked to Ryan over there who cleared up the drive shaft mystery. Apparently it is only the front that needs to be re-worked.
