With an optimized gear ratio and power ratio, it delivers exceptional handling strength while minimizing effort.

Reliable and Easy Installation

Mounting the Lewmar 40AST is straightforward, thanks to its well-engineered design. It requires five M6 (1/4 in) countersunk head screws on a 121mm (4 3/4 in) PCD for secure attachment.

When available, the warranty period is listed on the product page. If it is not shown, contact us or the manufacturer for details before purchasing.

To start a claim, the customer must contact the manufacturer and follow their process. Keep your proof of purchase and original packaging, and register the product if the manufacturer requires it, as these are often needed for warranty service.
