EVOLUTION LIMITED SLIP REAR DIFFERENTIAL SERVICE 

 

If your EVO is suffering from excessive understeer there is a good chance that the rear differential needs to be freshened up. We are now offering 2 versions; the "max-lock" and the "STU".

EXCHANGE SERVICE NOW AVAILABLE FOR THE MAX-LOCK

We now stock low mileage MAX-LOCK rear differential assemblies for the EVO-8/9.  These are perfect for those who can't have their EVO down for a week.  Click here for this service.

MAX-LOCK REAR DIFFERENTIAL UPGRADE SERVICE

We are now offering the MAX-LOCK rear differential upgrade. With over 200% more surface area and 60% more lock-up, the EVO will now rotate better when you get on the throttle versus understeering upon exit of a turn. Don't know what that means? Think Dukes of Hazard.

With the increased lock-up the EVO can even require some counter steer upon exit which means now you can quit trying crazy suspension settings to coax the EVO to finish the turn and focus on setting it up for max grip.  Autocross EVOs are knocking over a second off every 60 seconds of track length and road racers are achieving quicker track times due to the ability to use the whole track and  more conventional suspension set-ups and of course longer front tire life. Crazy now ain't it?  We aren't saying that this upgrade is the end all to making an EVO understeer but it has proven itself time and time again to be a worthwhile upgrade on stock suspension or the fancy 4-way adjustable stuff.

Turn around time is quick, about 2-3 days. This service includes: all new friction plates, modified side sheaves, magnaflux inspection of ring & pinion, shims, seals, adjustment of ring & pinion (if necessary) and a fresh painting so it looks like new again.

TRE-Spec: Maximum amount of lock-up available. Intended for those who have suspension upgrades.  $375.

1-way, 1.5-way and 2-way options are available by request.  Please check with me to see which option would be best for your application.

STU REAR DIFFERENTIAL REBUILD SERVICE

If your EVO is suffering from excessive understeer there is a good chance that the rear differential needs to be freshened up. We are now offering a STU legal rebuild that uses genuine OEM factory parts and assembled to the original factory specifications.  The rear differential assembly is taken apart and hot tanked. The clean parts are then inspected for wear  and are measured to make sure that they are in proper spec with factory parts. The ring & pinion and  spider gearset are checked for cracks using a wet magnaflux machine. The differential housing receives minor clean up work to remove any burrs that impede function. Afterwards all parts are carefully assembled to factory specs as published in the service manual. Expect it to work better than stock and to be 100% legal for STU.

Turn around time is quick, about 2-3 days. This service includes: new friction plates, new fill and drain plugs, magnaflux inspection of ring & pinion, shims, seals, adjustment of ring & pinion and a fresh painting so it looks like new again.

STU legal version:  $325.
