TRD Pro with 6112 coils (pics inside)

1. If I were to buy a 6100 full kit, would I be able to achieve the same results? Or is there more to upgrading from an SR5 stock platform like changing out control arms or other parts that would not have to be replaced when upgrading from a stock TRD pro?

A full 6112 kit would give you different levels of ride height adjustability. The other option is buying a takeoff TRD Pro suspension and just doing the spring upgrade. A-arms would not have to be replaced to run either set-up.

2. Also, for a moderately mechanically inclined person, is this a practical project for a newbie to DIY, or something that should be left to more experienced folks or a professional to do?

Not hard to do but coil springs have a tremendous amount of stored energy and can be extremely dangerous if not handled correctly.

Thanks for the info and the quick reply.

I have been watching a few youtube videos and it seems doable, but then pro baseball players make hitting a 90mph fastball look easy if I pull that up on youtube, so I'm just trying to get a feel for whether or not I am underestimating the process and the risk of damaging my truck by doing this myself.

Just got a quote to have 6112 professionally installed in the front with 5160's in the back and it came out to about $2,000, which sounds a bit high considering the parts look to be around around $1,000 total. Am I missing something or does that seem like a high cost for what looks like not much labor (at least in the eyes of a newbie watching youtube to judge labor involved)?

Thanks again for the info!
 
depending what are you live in, install labor rates and alignment costs add up quickly :party:

Thanks. I guess it was my old 5100s I was thinking of.

Well the first gen earlier 6112 released at the end of 2013/early 2014 did have 5 seat clips the manual had it measured at 2.5" of lift. So you might of recall those settings as well.

Current 6112 design model will give you 2.75" at clip 7 so the manual claims.

Has anyone done this with only changing out the front coils? If so, I would love to see a pic or at least hear if the rake leveled out or was more of a reverse rake. I understand that all of our rigs can leave the factory weighing a little differently which would in turn impact the initial coil compression. In the end, I feel like my pro coils aren’t giving as much lift as they should; when I park next to stock runners I’m practically level with them. I would like to get away with not doing the wheelers in the back if I don’t have too.

My Pro has a 1.25" rake in it stock. Only add is SSO Sliders which I can't see making a big difference since they are more or less centered. You're going to get right at 2" of lift from the coils so for me I'd sit nose high. No Cali lean for me!!! I'm going with a set of 599 Dobinsons in the rear. Should be a little taller in the rear which is what I want.

I guess I need to measure mine to see what it’s sitting at now and go from there.

Also, I called a Offroad shop in town to see if they might have a set of these sitting around and they did. They are actually the FJ version but the exact same dimensions and still #600. For those interested that PN is E4-FD1-Z005B50.

Yep. Good find!! Wish I had gotten those, only because they are red. Oh well this is only a temporary fix for me only I do the full Kings.

They are not red, you’re thinking of the FJ ultimate. These are the exact same coils you got, the only difference is this PN is for the “FJ” 6112’s. Same color, length, diameter, and spring rate.

That being said.... I’ll be painting them red.

Yeah I misunderstood ya. I was thinking about the others. I still may end up using these on the Kings if I'm not happy or need to upgrade the 550# springs.
 
so you put 6112 springs in the fronts and rear and kept the stock Pro shocks?

The 6112 springs are only on the fronts. I'm not sure what he used on the rears, Wheelers maybe. Yes you use the stock TRD Pro shocks and you must you the Pro Lower Spring Perches.

Okay so the 6112 springs in the fronts only and t13 in the rears :) but will this clear 285/70/17 with no rubbing? i believe OP has 275/70/17.
