rear leaf ?'s

i have a 10 taco dc v6 with s/c with 10k miles
i currently have the 3 leaf rear springs.
i was thinking bout using my extended warranty to get the new 4 leaf springs
im gonna be doing a lift soon. and wanted to know whats better?
i work at toyota. i have a brand new set of bilsteins off a 13 fj.
so when i install the lift(spacer for now as it was free) im gonna use the new struts and shocks. let me know what you guys think is the best way to go

 

Best way to go is to not use a spacer lift. But if you're able to get the tsb rear leaf springs for free that would give you a better rear ride height. Otherwise get an add a leaf.

 

yea i know no spacer lift but it was free and figured id use it for now
it rides fine with out the spacer lift
yea im gonna see if on monday they will cover the rear leafs and if they do im gonna install them. if not ill get the aal
are the rear leafs supposed to be flat?
im used to seeing jeeps and stuff where they have a curve to them

 

Yes the rear leafs are supposed to be curved. If they are flat you probably need more than an aal

 

its a 2010 with 10,000miles
was driven by a lady before i owned it
they look to be flat but its hard to tell they may have a lil curve to them
i know she used to pull a trailer and a atv once and while

i just looked at them and theres a slight curve to them

 

We'll go out in the lot and look at a brand new tacoma so you know what they are supposed to look like

 

thats my plan when i goto work tomorrow i work at a toyota dealer.

i measured the front from the ground to the top of the fender opening and it was 34 3/4
and the rear was 36

 

Measure from the center of the wheel hub to the fender. It takes the variable of the tire size out of the equation. And is kinda a standard on TW
If you still have a warranty I'd check the cams on your lower control arm before you get too far into your lift. Mark the cam bolts and tabs. Your going to have to get a alignment anyway. Mine were seized and Toyota wouldn't help me because my lift had been on for two days. You might not have that problem with Toyota.

 

my truck was stored in a heated garage all winter and only has 10k on it. i looked at another taco while at work and my springs looks just like theres so i think im fine
