Hey all, so I have an 87 4runner that I'm going to be usuing for a new job. Thus I will be cramming a box and tools into the back of my truck. And possibly a few speakers from my dad's suburb (2 15's ) so I was wonduring if I should replace the rear leaf cause its pretty much flat and I don't know if it can handle the extra weight. I'm thinking it will be around 300 lbs daily. Thanks!!!

 

Search first! There are plenty of better options then replacement OEM leaf springs.

 

Given the age, the fact that it is a 4runner, and the sag, you almost certainly need new springs, not to mention shocks. Spring sag/wear out is a well known issue here. The weight is not so much of an issue (at that amount anyhow). There are many threads here on the topic. You can basically get stock type replacements (less good given 4runner sag pretty much at baseline) or aftermarket type solution (better shocks and springs). Would recommend the latter, tho more expensive...tho again many threads here on how to do it [somewhat] cheaply

 

Sweet thanks. Guess I'm making this priority now. I don't want to find out what could happen if I don't replace them.... Thanks!

 

I am in the same boat as you. There are many options:

1. OEM replacements (JC Whitney)
2. Aftermarket (OME, Downey, Alcan, etc.)
3. Add a leaf kits (Long thin leaf for a softer ride I think?)
4. Zuk mod
5. 63" Chevy springs, Ford F-150 springs (57")

Search any one of these options...good luck!

 

Sweeet!!! Sounds good man

 

the Zuk mod i hear is a good idea if you don't off road too much. it give a little umph to the rear and makes a real nice ride... so i've read. the only experience i have are with the 63' chevy's and i love them.

 

And the cheapest fix......Air shocks. Fully adjustable height as needed (within a few of inches)
I don't suggest this is a great or even good mod, but it works and is cheap.

Not recommended for wheeling. They aren't built for that kind of abuse. 300lbs is no problem though.
