Picture of INSTALLING AN ADD-A-LEAF
For those of you who found that your truck’s rear suspension is not capable of handling your daily load, and lifting applications.  There is a great cheap way of increasing payload.  It will add some height, so make sure you talk with your local shop about the need for a new shock; or, do some searching and find an answer or at least an idea of what you need. 
Here is a quick guide of how to install an add-a-leaf.  I recommend purchasing a repair manual (Chilton) from your local auto supply shop for your make and year to help removing original suspension; or with a little of research figure out how to remove yours online. 

Beware this procedure is DANGEROUS!  Can cause serious injury if not done CAUTION!  I take no responsibility for any damage that may come to you, helper/s, bystanders, yours or other’s vehicles.

Even with the extra leaf, that suspension looks suspiciously flimsy to my eyes. That much truck needs more metal under it.

This truck has been tested out in an 4x4 park getting air off of whoops and feeling great!!! Japanese engineers built a solid truck, designed to limit the need for extra metal... TRD knows there stuff!!!

Also, two dirt bikes, loaded down, dirt wash board trails... No Issues.. Love this truck, highly recommend to Tacoma owners!!

Fair enough. I come at off-road suspension from a Jeep angle, meaning I want my vehicle ready to transport a small army to gates of Hell. Or Utah. Whichever.
fyi to you nay sayers the 4.0 tacoma has a 4 leaf now and it can tow 800lbs. more than 1500 chevy.
only three leafs is suprising that it does good, i run my rig with 5 leafs on it
