Stock leaf spring differences (TRD vs non TRD and Stand./Xtra/Doublecab variations)?

I can't find a definitive answer to thsi question. Are there differences in 1st gen leaf springs (stock OEM) between various models?

Most threads I found seem to indicate there was no difference in TRD vs non TRD, but then I found this blurb on a random site: ". The leaf spring suspension in the back also has been modified to improve off road performance." So now I'm confused again. Also trying to really nail down is double cabs had different leafs than Xtracabs.

I have a 2004 TRD Xtracab V6 with 133k miles on it, and while I replace my shocks I was thinking I'd try and snag lesser mile leafs from a scrap yard and put them on to freshen the truck from that aspect. I found some non TRD Double cab ones, but I have no idea if they are the same as on my TRD Xtracab.

Anyone know?

Thanks

 

I read on here somewhere that the TRDs have an extra leaf over the base models., but I have no hands on proof.

As far as getting leafs with fewer miles from a scrap yard, the amount of miles on the leafs doesnt matter. They condition is mainly based on what the truck bed was used for. A truck with 80000 miles that had an empty bed its entire life will have leafs in better condition than a truck with 10000 miles but was filled with 400lbs of tools 24/7.
Unless the leafs from the scrap yard are really really cheap, I wouldnt waste the money. Instead I would put that money toward a new set of oem style leafs or aftermarket (wheelers/alcan/ome/deavers) leafs.

 

Thanks. The leafs would be free. Lol. It's amazing how hard it is to get an answer on the differences in leaf spring packs!

 

My stock 2000 SR5 had 3 leafs and an OL. Idk if that helps haha Mine broke at 130k miles.. the driver side..

 

Back in the day when toyota marketing was touting the trd package on 1st gens, they did make the claim that the package includedd upgraded springs. I don't recall any specific statements about the rear leafs but there was a definite design difference between trd coils and non-trd coils.

In reality, there are no fitment differences (coils or leafs) between trd and non. I've owned both. In my opinion, neither type is all that great when new, let alone with 100K on them.
