OEM Leaf Spring Lifespan

I recently changed out my entire suspension. The original OEM suspension had 80,000 miles on it and had the crappy TRD Sport shocks/struts. Essentially, the truck was riding like a covered wagon. Plus the leaf springs were rusted and a bit saggy.

I installed basically brand new 2021 TRD Off-Road shocks, struts, and leaf springs that I got off of Facebook Marketplace for a few hundred bucks. I wanted an improved ride without paying $4,000 for the suspension I eventually plan on installing, and I definitely succeeded with that.

ANYWAY, now that y'all know the context, I am curious how long everyone thinks these new OEM leaf springs might last me. I know the OEMs are notoriously weak-ish.
They have a 2" add-a-leaf, and will soon be paired with the Archive Garage Hammer Hangers. Oh and I also have about 250 lbs of constant weight in the back because of the bed rack and rooftop tent.
The truck is pretty exclusively driven on pavement and forest roads. Nothing too rough.
I know I have bought myself A LITTLE bit of time before I need to upgrade to aftermarket leafs, but probably not that much time.

My Tacoma is also a Double Cab LONG BED, so I know that changes the spring dynamics.

So my question is, how long do y'all think I have before these new OEM leaf springs are toast? Given all of those variables.

 

I had the OEM 4 leaf-TSB leaf pack last me less than a year after 1 camping trip with a bed full of fire wood effectively turned the leaf pack into a W-shape.

Then the TSB came out for the OEM leaf pack replacement due to the potential to break a leaf and puncture the gas tank. I was more mindfull with this leaf pack and never loaded the bed with more than 800 lbs of stuff and that lasted me 2 years and 65k miles until I upgraded to an all-pro expo leaf pack.

I think that pack would have lasted me 120k miles if I didn't upgrade. A good average is that the OEM leaf pack & OEM shocks will last 100k miles if not overloaded (which is really easy to overload) or 3 years on the OEM shocks b/c of loosing pressure over time if you're not a high mileage driver.

 

"toast" ? probably longer than you'll own the truck.

but they'll usually start sagging/squeaking/riding kind of "poorly" in about the same amount of time as your old ones. I think 100k is about the usual time frame for that, depending on usage.

 

That is some AWESOME input! Thanks so much for that information

My hope is that I can at least wait to replace them until I do the full upgrade to the Dobinsons MRRs and leafs I want to eventually get.

 

With constant weight I've seen them break around the 6 year mark. They usually start to sag around the 3 year mark with normal use.

 

That would definitely be ideal. If I can get some good use out of them over the next few years, that will be more than enough

 

That sounds pretty close to what I was thinking too.

That should be right about the time where I fully upgrade the suspension, so that would be just fine! Fingers crossed

 

The OEM Springs are crap. I had mine replaced under the tsb recall 6 months ago. I thought it would help with the rear sag. It did not. That is with my helper spring on also.

 

LOL sounds about right!

 

I don’t know what it is about these trucks but to me 95% of the ones I see on the road look low in the rear.

 

When I had my frame replaced 3 years ago they replaced my Wheeler's leaf packs with the OEM leafs without my consent.
Here's what I found when I picked up the truck...
I had to dig my leaf packs out of the dealership scrap pile and take them home to replace them the right way.
Yea, I drove home like that
with air filled brake lines and an overfilled brake reservoir.

 

Jesus

 

210k on my odometer and I’m still rolling around on the factory leafs (replaced a couple years ago on a recall).
