what is a rear spring TSB

i no its a noob question but still i was wondering what a rear spring tsb is

 

(Technical Service Bulletin) the most common TSB talked about here is the 4 leaf springs on the rear, if your truck only has 3 leaf springs on each side of the rear of your truck then you qualify to get the 4 leaf springs under toyota 36,000 warranty free of charge, by looking at your info you have a OFF ROAD 4X4 2008 TACO, you will qualify to get the 4 pack leaf springs just go to your dealership and tell them that "MY TRUCK BOTTOMS OUT WHEN I LOAD A HEAVY LOAD ON MY TRUCK AND THAT I WANT TO GET THE TSB DONE" i have a 2009 TACO and i got mine done back in OCTOBER of 2008 but some people that have 2009 TACOMAS arent so lucky to get the 4 pack leaf springs because the TSB only applies to 05-08 TACOS, so youll be good, Hope soon theill add the 2009 and maybe the 2010 to the list

 

Does this affect the ride height ?

 

Lots of stuff about the TSB on this site...

Here's a good start

 

This is news to me. good heads up

 

The rear of the truck will be raised a little but you really wont tell a difference but the ride quality is much better

 

You can definitely tell the difference in height. It is a little over an inch after it settles.
