'13 TRD OR 3 leaf pack

Thought they went back to a 4 leaf pack on the OR?
The Sport has 4, the OR 3.

 

OR has a supposedly stronger 3 leaf pack. Sport has 4.

 

OR has 3-leaf (supposed to be newly enginnered?)

Sport and SR5 have 4-leaf in 4x4

not sure about prerunners

 

Doesn't really matter...OEM springs aren't terribly durable...recommend aftermarket pack when (not if) your OEM springs wear out.

 

This will be the case. Was just curious about them putting a 3 leaf pack back in after the TSB.

 

with regular use...at approx what mileage should one expect the rear springs to wear out?

 

About a week

I don't understand this

I assume Toyota equips the Offroads with a 3 leaf pack for greater articulation , why would they then re-engineer this pack to be as stiff as the 4 leaf pack for loads rather than just installing their 4 leaf pack

I call BS , it's the same old 3 leaf pack as before

 

Mine lasted two years with regular wheeling but wasn't daily driven. This was tsb pack with add a leaf. Maybe 12000 mi of use?

 

My 4 leaf pack flattened by over an inch in 4 months hauling a 350 lb toolbox daily

 

You guys must have bad luck

my 2010 with TSB springs were fine for the entire 26,000 miles I owned it. And I hauled materials and tools regulary...towed a small boat too.
