Steeda Differential Bushing Bolt Upgrade Hardware

[5ohh_kenny]

Nothing against Steeda. Just not sure socket head bolts were the best option for this application. For two reasons.

1. This is a major flaw... When installing the forward most bushing up against the fuel tanks it’s impossible to get a socket on the bolt unless you completely drop the subframe out of the car. I had to use some vise grips on the circumference of the bolts. Luckily these only need torqued to 37lb-ft. Doubt I even got that before the vise grips started to slip.

2. The socket head bolts are 12mm hex. If your a DIY guy like myself I doubt you have a 1/2 drive 12mm hex. My dumbass bought a nice sunex set but got 3/8 drive. Good luck finding a 3/8 torque wrench that goes up to the specified 129 lb-ft torque. This is less of an issue and more of an FYI. You’ll need a low profile 1/2 drive 12mm hex to install these socket head bolts.


EDIT:
These would still be a great option if your dropping the subframe anyway.

In order for us to get the proper bolt length in a grade 12.9, the strongest metric offering, the only option is a socket head cap screw (allen head

Wow that was a quick response.

I didn’t think of that but makes sense.

Even if they were a pain to install nice to know I have the best possible hardware back there for boost and trips down the 1/4 mile.

Thanks Steeda!

Boost and quarter mile...with a manual or auto?

If manual, I would highly recommend doing more than just the bolt upgrade. I don't care what anyone says, diamater is the best solution to preventing the bolts from shearing. Stepping up to a 12.9 from a 10.9 isn't that much of an improvement. Maybe consider additional diff bolt support like their diff bracing system.

That's what a tool budget is for . . . doesn't have to be an official line item in your finances, but as a DIY'er willing to tackle new projects you pretty much need to have this. Even if it has to come out of the beer budget from time to time.

I just ran through this whole project & can back up Steeda on this one. 12.9's of the right length are SCHS only. You have to drop to 10.9 to get a hex-head.
