8.8 girdle

I think they're thinking that if you know how much goes in, it isn't an issue.

Right, I hear ya ...
... but in my case (and many others I'm sure) I usually just buy those gallon jugs of gear lube and a tube of additive ... now lets say I have a jug that's around 2/5's full ... then I've got to figure out how much of my 2/5's gallon of GL-5 I'll have to add to the diff :scratch: ...
I can always simply just stick the hose into the factory plug and pump till she's level and be done with it .. so much for girdle fill plugs :notnice:

No one with these two girdles above can answer this :shrug:

You have to remove the stock fill plug and fill through the more accessible plug on the cover until it comes out of the stock fill hole. There is no real way to know exactly how much it will take because another feature of a girdle cover is that it adds fluid capacity to let the rear end run cooler.

Exactly .......
 
The girdle is a good idea, although I don't know that you need it to run in the 12's. My 7.5 in c-clip axle has lived for a year in the 12 ish range, including a few sprayed launches. Cross your fingers for a few more months...

The 8.8 is in the garage waiting....

Sure, that makes sense.

The thing that makes me curious though is with the TF girdle. It seems to be the only one on the market with the fill plug lower down on the girdle. I wonder if they actually located it relative to where it should be :shrug:

Because if it is located too low (lower then stock location), then it would make it an unnecessary feature. I'm under the impression it is correct and they are one of the only ones that actually did their homework.
 
Well, I care so much that I called Trick Flow ...

The rep said their fill plug was designed to be in the stock heigth location ... you just fill the diff to their plug ... so IMO this makes this the best girdle to buy :nice:

I have the FMS and I agree with you. The TF seems better for 2 reasons. The first, the fill plug in a usable place without having to remove the dogbone from the rear to access the factory fill plug. Second, the jam nuts are accessible from the side on the TF. Look at my FMS picture and you'll see the jam nuts are recessed. The problem in that the inner bolt is NOT supposed to move when tightening the jam nuts. I ended up using a spark plug socket, putting a wrench on the outside of the socket to tighten the jam nut while I ran an allen head through the center of the socket to hold the inner bolt. crapola From the looks of the TF, you can just use a open ended wrench to tighten the jam nut while you hold the inner bolt with an allen wrench .... much easier.
 
i have the TF one...its leaking so i have to get a new gasket for it this spring..but im going to look closer at it to make sure its not leaking out of the screw threads....cant remember exactly how your suppose to tighten the cap supports??

but i do remember the directions said to fill the diff. up till it comes out the fill hole...

i pic of the TF cover dosnt show it..but mine also has a drain plug...
