Differential Plate Stack Settings 2023-08-15

Blair has had a few people asking how they can adjust the differential lock up. We set the differential to the medium friction / medium lock-up configuration in the factory. Most of the time we leave it there and never touch it. If you find in a particular scenario you are spinning the inside wheel coming off a corner you can increase the differential lock up by adjusting the clutch plates to the High friction/ high lock-up configuration. Similarly if you find that power on exit is causing an exit understeer you can reduce the lock-up by going to the Low friction configuration.

Please note this is mainly driver preference and is NOT a typical tuning technique. The diff is adjustable by virtue of its design, most will find the factory setting most preferential and will never adjust it!

The picture below shows the clutch plate configuration for the 3 options. Please also note it takes a long time for the diff plates to seat in as there is really not a lot of movement during use. Dont confuse a broken in diff with a worn out diff as you are able to spin a wheel by hand easily as compared to new when you have the wheels off the ground. The diff is doing NOTHING unless being loaded through the drive gears.
