If you have been following high horsepower Hellcats, there is a point where the increased HP/TQ with an upgraded driveshaft can lead to differential failures.
Two issues have been reported from members: Case failure or Gear failure
As you can see in the pictures below regarding case failure, the case cracks and breaks away from the rear cross-member. The issue here is the driveshaft can be damaged or even disconnect from the differential and cause other more expensive damage and increase crash potential.
With the input of some of our forum members, for the past 3 months I've been developing a brace to significantly reduce case failures without any unintended consequences. The design has been modified twice. Here is the latest prototype on a forum members Hellcat Charger.
The brace anchors to the rear cross-member where there are two existing threaded holes and connects to the two main differential bolts. It is buttressed by a durable 1" nylon guide and 3/8" 65-70 shore rubber isolation material. The braces will be powdercoated silver.
One will be going on my 815 RWHP Hellcat Challenger as soon as the initial production run of 25 units is completed.
These will be available for purchase in 3-4 weeks...if you are interested, please let me know via PM.
FYI - I am a Hellcat enthusiast/Forum member and have contracted these to be made by a local, high-quality fabrication shop where I have known the owner for years.
Thanks, Bray
