Parts worked great with installation instructions
I was pleased with the parts & instructions for the install, but wished I would have received sooner. Might want to try USPS on small items.

East Repair, replacement part fit perfectly, running just like new!
Part was packaged well, arrived quicker than anticipated, the module looks like it is different, but it worked perfectly for our 2009 LGT 2554 with a V730 Kohler.

Part was correct, fixed my problem and got me back to mowing
The parts were the exact fit for my mower. I like the fact you can see a diagram and picture of your part before you order. That way you know it’s the right one. The parts were small, probably no more than 1-2 pounds. Would have been nice if they were shipped with USPS instead of FedEx. FedEx seems to do better with big things, but this order took longer than it said it would. Other than that, no problems and will use ereplacementparts.com again.
