Hello all, I recently purchased a one owner stock 107k mile all original 86 4Runner SR5 that's in immaculate condition off of BAT. I know these sagged from the factory. What are the best non-invasive options to level the rear? Has anyone installed 1.5" rear blocks, or should I be looking at replacement springs? I really want to keep it stock and original, and do not want to do anything that can't be reverted back to factory since this is such a clean and original 4Runner.

Here's a pic of the truck. It spent it's entire life since new in California. I'm still in amazement of it's condition.

that looks like a nice truck... sag in back is apparently a common problem, i've seen several options to cure it, for instance the zuk mode?

blocks under the springs would not be stock, afaik, although there might be a shim under one side, from the factory(?).

Easiest and cheapest way to life the rear just a little would be some greaseable shackle extensions.

What about an add-a-leaf? My 4Runner had aluminum blocks at the back. Raised it just enough that the parking brake cable dragged over the leafs and made the parking brake hard to use. If you go that route check your cable clearance first.

just went to BaT. Pretty clean!
I like that it still has the factory catalytic converter. Never throw that away.
i was also impressed that the vin stickers were still on the fender and hood. Those can’t be replaced (unlike the one in the door jam or under the windshield), which would mean the fenders and hood are the original ones.

Congrats on the purchase. I was watching.

I’ve done the zuk mod on one of my rigs and it’s a quick, low-buck bandaid which adds a small coil spring on each bump stop in the rear. Even with 100lb/in springs it’s pretty stiff, more so with the soft top on, of course. Going to a spring shop and having them re-arch yours is probably the best option for a stock height and ride.

Disregard on the pics just checked it on BAT, looks incredible

Add-a-leaf is the way to go. It will definitely give you the best ride out of the non-invasive options (Zuk mod, lift block, extended shackles). it will give your leaf spring more flex before hitting the overload leaf (STIFF), but when loaded down the overload will work as intended. There are a few universal options, beware of Thick & Short add-a-leaf springs, they will make for a stiffer ride.
