    Can anyone with REAL knowledge weigh in on this... Is there a difference is coil spacing or resistance between the RIGHT and LEFT side stock TRD Coils?

    I just installed my billies at 1.75" about a month ago and I am now starting to see the dreaded taco lean on the drivers side.

    2012 4x4 at 1.75" front with TRD Sport Stock Springs

    Thanks,
    Frank

    I've been told several times that the coils are side specific. People who have switched them ended up with some serious lean, meaning the passenger side is an inch taller than the driver's side. That being said, I've got no idea how to tell them apart.

    Yeah, that is the issue... I am going to check the official numbers off this weekend when I get a chance but I was hoping to hear it from a master tech or a toyota tech guru on here...

    Doug (4WD) had something definitive. My coils at home are assembled so I can't look at the bottom of the coil to confirm his findings. Plus I'm on Eibach's now so I can't just run out and check.

    How much lean is it? If it's half an inch or so why not just get the 1/4" top plate taco lean spacer from toytec and call it good? Doesn't require longer strut bolts or nothing - cram it in there and wallah, level. FWIW, my base 05 prerunner had the lean but the 08 sr5 didn't and they both had same black tokico fronts. But I did use TRD coils when I put the 5100s on the 05...still had the lean until using the spacer on drvr side. Another thing...are you sure both of the spring perches face the same way when setting the 5100s at 1.75?

    I will check this tonight but considering it was a pro lift shop with a huge following I would hope its all correct.

    That would make worlds of sense, but even when you purchase aftermarket coils they don't specify a difference. My truck had virtually no lean stock, then I installed a lift and I have enough lean this time to make up for not having it the first.

    I don't have a TRD

    Aftermarket coils are not side specific, stock coils are.

    Thats my point. My stock coils kept the truck level and my aftermarket one didn't. Thus reinforcing the idea that stock springs have different rates per side. My first post was admittedly not clear sorry about that.

    If they (aftermarket lifts) would increase the spring rate of the coil on the drivers side to accommodate at least the weight of a full tank of gas it would greatly help.

    I see what you're saying now, sorry I misunderstood your first post.

    I've got the 1/4" spacer on the driver's side and I still lean with my Eibach coils :(

    lol that damned first post was very easily misunderstood. I was typing without forming a complete thought apparently.

    Well the general consensus was correct the STOCK springs are right/left specific. I took a measurement this morning and there was 1" difference from side to side.

    Needless to say I now have things corrected (I hope).
