Stainless Cowling Kits replace the old, worn and rusted parts originally installed on your cowlings and access panels with exclusive Skybolt CLoc®, ZLoc®, or ALoc® style stainless fasteners. Many kits depicted may only replace certain portions of the engine cowling. Optional kits to complete all panels are available. The unique Skybolt Cowling Fastener Replacement Kits were developed over a span of 5 to 6 years utilizing Parts Manuals (IPC), field research, and customer feedback. We soon discovered that the Parts Manuals were very inaccurate and relied more on field experience. Despite exhaustive data, we also discovered that no two aircraft were ever the same. The Skybolt Cowling Fastener Kits will usually contain more of a selection than the aircraft may actually require so that a replacement project can efficiently move from start to finish. Like the Trim and Fuel Tank Kit development, many companies began to copy the Skybolt Cowling Kit product line only to discover just how difficult it is to understand each and every production aircraft produced from the 1940s to date. Without the supporting data to back up the fasteners required on most aircraft, the copy kits can supply about 70% of the required hardware. Skybolt’s goal is 100% in all of our kits. Cowlings are our business. As many of these kits can cost hundreds of dollars, you deserve the best product on the market and a company that can stand by your investment for as long as you own the aircraft.
