Kohler engines and shortblocks weighing under 70 lbs may ship UPS Ground. Engines and short blocks weighing over 70 lbs will require a commercial business address for delivery. We can't ship to your home, home based business, church, farm, school, prison or any other facility with limited access. The business needs to be open normal busines hours Monday - Friday. Truckline shipments normally take 2-5 business days depending on your location. They do not call in advance since there should always be someone at the place of business. Examples are:
- Lumber Yard
- Auto Parts Store
- Shipping Warehouse
- Lawnmower Shop
- Auto Repair Shop
If you are not able to locate a commercial shipping address, please give us a call and we may be able to arrange shipment to a truckline dock in your area.

If you need additional information on kohler engines or shortblocks, please give us a call. We can help verify this is the correct engine or short block for your application.
