TRD Pro front springs on 2011 SR5????

[RattleAKAK]

Gentlemen,

So I looked around and couldn't find any solid definitive info. I have a bead on a set of new TRD Pro front springs for cheap (what I think is cheap) and want to know if they would provide any front lift (leveling) to my 2011 SR5 or even fit. I tried searching prior to asking this question to no avail.

Thanks

The TRD Pro shocks are 2.5" in diameter, so whether the springs will fit or not depends on your shocks and the spring seat. If you have OME, Bilstein 5100s, Dobinsons, etc. they will not fit. A different 2.5" shock WITH THE SAME SPRING SEAT technically could fit, I guess. The TRD Pro shocks were built off of the Bilstein 6112s but I don't know if they have the same spring seat.

What are your shocks? Are you spending a lot of time offroad? The most inexpensive level is a simple spacer... but that seems to have become an evil word around here anymore.

My 2011 SR5 has factory shocks. I was under the impression (according to pictures I've seen), that the TRD Pro coils were 3" ID, 3.5"OD x 13" long with #550-600 spring rate. I cant find the SR5 coil spring dimensions or spring rate to paper compare. I was hoping to use the TRD Pro coils to get the truck level while possibly firming up the front end and lose the brake dive.

The TRD coils aren't going to work for you. You are correct about those dimensions, some of those pics were mine :hatsoff: haha. Besides the fact that they're the wrong size for your OEM shocks, the other issue you're up against in trying to put a longer spring on your OEM shocks is that a longer spring will make the shock travel different- the shock will be extended further than intended during normal functioning. This may or may not be a problem but I personally wouldn't want to chance it.

Your two cost effective options are either spacers (less than $100) which will level the truck and preload the spring, firming up the ride, or a set of Bilstein 5100s (~$360 from totalautomotive) which are ride height adjustable in the front and you can use with your OEM springs. The ride will be a touch firmer, less brake dive, and they actually improve wheel articulation (travel) compared to the OEM shocks since they're longer.

Either way, remember you'll also need an alignment (usually about $100) any time you change your suspension geometry. Whichever you decide, good luck.

Thanks for the info, Yeah I saw that was yours haha:cheers:. When you say the "wrong size for the shock" length aside, are you talking OD? Man if you had the measurements of a SR5 spring that would be great for me to wrap my head around.

Thanks again!!!

Yeah wrong shock diameter for the spring as well as seat itself, at least that I'm aware of. :cheers:
