This is service is for the factory front limited slip differential.

 

PROBLEMS WITH THE FACTORY FRONT LIMITED SLIP

Your factory helical front limited slip differential has been proven to work very well. However it has some problems with the housing cracking when the vehicle is used for drag racing. 

The problems:

  • The housing has a nasty cast surface.

  • The corner radius is too tight wear the planetary gears reside.

  • The induction hardening ends right over this highly stressed area.

A SIMPLE SOLUTION

Now, you can drop a lot of cash on a Cusco, Kaaz, Quaife or Wavetrac or you can save yourself some money and just have your front differential housing gone over by us.  It's worth every penny and we have not had any fail.

  • magnaflux inspection of the outer housing

  • magnaflux inspection of the sun and planetary gears

  • machine work to the housing

  • shot peening of the outer housing

DETAIL THE HOUSING

We start by magnafluxing the housing, making sure that the housing that is not cracked. Afterwards the housing is machined to remove the casting features and to add the larger corner radius.  This is also done on the inside of the housing to eliminate the planetary gears from loading this area with excessive force.

 

 

SHOT PEEN THE HOUSING

The outer housing is shot peened both inside and outside. Surfaces that are precision ground are masked off so they don't get peened. It's done right. 

Street Tuned Motorsports ran the factory limited slip front diff with this service in their 8 second drag EVO for 3 seasons without trouble.

TRE also has new replacement housings if yours is busted.
