Rapid Rebuild

You spoke and we listened – when your bike is down you want it fixed right and fast. Who better to repair or upgrade your Factory Harley, Big Dog or out of warranty BAKER transmission than the Drivetrain Authority themselves?!

With our Rapid Rebuild program you have our promise on two things; First, that your transmission will be repaired or upgraded by the best in the business- right in the BAKER Headquarter Facilities and Second, that it’ll be fixed as quickly as we can. You can count on us for a quick turn around with your repair or upgrade, at the most reasonable rate.

You can send us your non-working stock transmission for a full diagnosis and replacement of broken parts, or even your old and tired stock transmission so we can replace the internals with an upgraded BAKER gearset of your choosing – and all in just a week’s time! Talk to your sales and tech guy today about our Rapid Rebuild program for more details!
