We are pleased to announce the release of our newest heavy-duty driveline product specifically designed and engineered for the 2005 manual C6 Corvette. This product is a solution to the current problem of differential/transmission case fracture due to severe driveline deflection that occurs during hard acceleration on the street or strip.

Like both versions of the already successful C5 differential strut; this model uses the same engineering concepts to control the violent "wrap-up" action the driveline is subjected to that often shears the differential case away from the transmission mounting flange, which causes catastrophic damage to both in most cases, requiring expensive replacement.

The major difference in design between the C5 and C6 differential strut models is that the C6 design does not have lower strut rods and/or related lower transmission brackets like the C5 counterparts have. This is due mainly because the O.E. Getrag C6 case already has dual, lower differential mounting pads that partially act to correct the negative "wrap-up" issue.

We state "partially" because we've found that GM/Getrag didn't go far enough to solve the negative "wrap-up" issue that breaks these units and the current C6 differential design is just as prone to differential case fracture as the C5 models are~ just in a different place...


The main point of weakness and area prone to failure in HP applications are the mounting pad side covers themselves. The O.E. mounting pad "wings" are completely hollow, therefore lacking any real strength, which in this case makes them inherently weak for high performance applications use due to their original design. There is no significant structural strength in these hollow "wings" to support the extreme shock loads of high performance street/strip use, therefore they rapidly fatigue, crack and shatter~ often taking the rest of the differential to pre-mature failure with it.

Our new C6 Differential Strut fills that engineering gap by providing additional driveline strength on top of the differential itself using the same design principles as the C5 models, which functions in tandem with the current two lower C6 differential mounting locations that are already engineered into the Getrag case.

All of these driveline strengthening refinements and additional "girdling" around the differential case itself our product provides, culminates to one final solution to preventing catastrophic C6 differential failure for HP applications.

Pretty sweet.

 

I still haven't looked underneath my car, so this may be an ignorant questions, but... Can this be installed on a lift without removing the tranny or rear end assembly? Also, I noticed that you mentioned specifically M6 trannys. Is this part needed for A4 C6's w/ drag radials and an extra 200-250 pounds of TQ? Thanks in advance.

 

We have installed this kit on vehicles in our shop without having to remove or drop the rear sub-frame and our detailed instructions reflect that. However, some of our customers prefer to lower the sub-frame down anyway to make it easier for them. Either way is fine and is quite effective.

We've designed the M6 model first (as we did for the C5) due to the majority of the current breakage occuring thus far has been with the manual-equipped cars. The A4 version are in fitment-development now, but their release won't be for a while yet.

 

The C5 girdle was approx 26 lbs, if memory serves.
With less material, is the C6 girdle significantly
lighter?

Incorrect..

Over the last year and a half through product refinement, we've whittled down the weight of the C5 M6/M12 model to 19.7 lbs and the A4 model to 18.3 lbs. The C6 strut is lighter than either of these two.

 

You might want to update your web site -- it says 26lbs
and also says the A4 version is still under development
for the C5.

We are doing just that now..from one side of our website to the other.
