I wanted to do some more research, because the last thing I want to do is destroy a perfectly good shock for no reason. After digging through the Dobinsons thread, I found out why they canceled the project. All quotes are from Dobinsons Mike, a well known suspension guru here on the forums.
Post #1071: "Just because we can make a taller and stronger coil for these struts doesn't mean we should, so we have to test the product, and also watch the market and see the demand. The 1" lifted coil is a very minor upgrade, but the 2" doesn't leave a lot of down travel in the struts, and historically, struts left riding with minimal down travel end up topping out repeatedly until the top seal blows."
Post #1140: "They're not even recommending any coil [Bilstien] other than stock on their struts. Look here: Broken Bilstein 5100 FrontS I know they're 5100's and not Pro/6112 Struts, but still."
Post #1244:"We didn't get that far to check the down travel. I don't think the struts are strong enough to handle the extra lift."
There were a couple more quotes that I lost in the frenzy of open tabs. Whoops!
I don't think Dobinsons spent a ton of time doing in field testing (a few months on a couple vehicles according to the thread) with the 14x3 HD coil, but they are suspension experts, so I take their word. However, nothing beats testing the real deal. I'd love to hear how everyone's shocks are doing after several thousand miles of testing.
At the moment, I think I am going to hold off on the 6112 14x3 coils due to the comments made by Dobinsons, but I would love to be proven wrong by folks actually running this setup! |
From the research I conducted, your shocks from the TRD Pro are the same shocks as 6112 shocks. The only difference that I heard is 6112 shocks have multiple settings where as TRD Pro coils are preset to the highest setting. I have never compared the two in person so I cannot say my statement is 100% true. Just the research I did. I guess time will tell how my vehicle's suspension will perform. As of right now it drives awesome. Also, Eibach is looking into making coils for TRD Pro for higher load.
As far as Dobinsons, I was under the impression that they were going to make a longer (15 inch) coil not just change the load. This would make the coil 1 inch longer than 6112 or 2 inches longer than TRD coil without changing the load. 6112 14in coils only will make your vehicle go up a inch plus change the load which gives our vehicles a approx. extra .75 of lift over a stock TRD Pro. Again, I am not a engineer or a professional mechanic. I am just a normal person whom is try something different. I believe this setup will function well and it will be tested out this summer.
