Any experience with the Ronin 8.8 rear diff kit for the FD??
Just recently, got a ford 8.8 rear diff and I'm looking to see if anyone has any experience with the Ronin kit. I'm interested in purchasing but haven't seen anyone talk about their experience with it.
if anyone has links to or any additional info please let me know.
I will be posting an article on my Ronin install shortly. It's a great kit, but its important to set the pinion angle when welding the x-brace in. Lmk if you have any questions. What gear ratio and limited slip diff are you using?
Running 3.55, I was debating maybe running 3.31 not too sure. Trying to get more info. I was looking at this Kit. Looking forward to your post.
Why are you interested in such tall gears? What are the details of the rest of your build? Most Explorer diffs have a 3.55 so you might only need the rebuild kit and LSD. Depending on your application, the traction-lok that you posted might be a good fit for street and occasional track use, which is similar to a stock Mustang's LSD; however for more power or performance-oriented usage might make a TrueTrac a better fit.
I have one in my fd and im using 3.27 gears and a t2r torsen in it. I kept the original rubber bushings in the front and ended up cracking the front passenger mount because of the flex and had to have it welded back together. I swapped to solid aluminum bushings and reinforced both front mounts and have had zero issues since. Id go poly or aluminum to avoid this from happening. 550rwtq is fun lol
^Holy crap, you did that with just 550rwtq? Talking to Joel at Ronin, he's never mentioned that kind of failure, and i've never seen that before. I'll have to see if he's aware of it. I'm going to assume you have an LS3; is it a street/track/drag/drift car?
For Spintowin: The T2R is MUCH better than the T2, but personally I like the Truetrac which is a lot less expensive and similar (if not slightly better/stronger) in performance than the T2R. But the T2R has changed a few years ago and I have not heard about the same issues and failures in extreme conditions since then so durability and performance wise, the TrueTrac and T2R are virtually identical.
I'm still learning what route I'm trying go (still learning about this). I'm leaning towards the Torsen T-2R from the research I did online. I'm still trying to decide on gearing & looking for more info. Maybe you guys have some recommendations. it will be a 13b-rew running it at 550rwhp but planning on pushing it more as I get more comfortable. I plan to use it for street, autocross, and touge runs. Might stay with the 3.55 gearing. I'm running the stock trans but it's going to be built by liberty gears.

Having raced both of them and using both of them in personal cars and daily drivers, I would get the Eaton Detroit TrueTrac ($690) over the T2R ($875). The TrueTrac use to be sub $600 until recently but even for the same price, I would probably go with the TrueTrac. You can't go wrong with either but the T2R does not have any real advantages over the TrueTrac.
That power is borderline for the transmission, where the case flexes and causes the gear stacks to separate and then shear teeth in the gears (mostly 3rd). But depending on how you drive it may be fine. I was keeping my stock trans with the 550whp goal but now that has jumped to mid-high 600whp and I went ahead and upgraded the trans. What turbo are you using? I think the 3.73 or stock 4.10 would be better for togue and autocross. Depending on your budget I would pick the TrueTrac and the 3.55 that comes with most Ford 8.8's rather than a more ideal 3.73 and that Traction-lok diff you posted. But look at the different prices of Explorer 8.8's; there are some 3.73 equipped diffs out there for a little more money that might be worth it vs buying a new gear.
Perfect, about to order the Easton Detroit TrueTrac. The turbo is a g35-900 1.06. The ford 8.8 diff I have comes with 3.55 gears, I'm planning on getting a rebuild kit for the diff and wondering if it's just worth upgrading to the 3.73 gears. The rebuild kit with the 3.73 gears (I found some negative reviews about Yukon so not sure if I should really order from them). Found this 3.73 gear by itself but having trouble finding a kit to rebuild the diff with. Any suggestions before I order?
You could match the stock 4.10 final drive or 3.73 I don't think you could go wrong with either. I got a Motive Gear off Amazon; it was $230. I got the Grannas Explorer Master Overhaul kit for $246 - you can find them a lot less but it doesn't appear most have new side axle seals; which needed to be replaced on my diff.
