If you are not sending a diff into be built, and you need an exchange differential, a fully refundable core deposit of $200 is added. If you do not return your old differential, you will not receive your core deposit back. Return freight is available. The differential returned to Diff Lab must be the same as the one supplied.
At present Diff Lab only has 3.91 differentials for exchange. All other ratios must be sent in for a rebuild. Turn-around is generally one day.
