In the trim kit fasteners and accessories product group, you will find parts for installing and maintaining trim levels: Lenco working cylinder lower and upper fasteners, Lenco XD and XDS cylinder lower fastener, Uflex cylinder retrofit upper fastener, Ultraflex trim plate bellows kit, and Lenco cylinder mounting pin in a pack of two.
The trim tab cylinder is attached to the boat's hull and the trim tab itself using separate fasteners that wear and fatigue over time under constant movement and load — failure of a fastener while underway can cause uncontrolled movement of the trim tab, so timely replacement of worn parts is both a safety and performance issue.
Bellows protect the internal parts of the cylinder from water and dirt — cracked or worn bellows will allow water into the cylinder, which can cause corrosion and ultimately cylinder malfunction. It is a good idea to check and replace the bellows regularly, especially before a long sailing season.
Brackets are manufacturer specific: Lenco and Uflex systems are not cross-compatible, so always check which manufacturer's trim panels your boat has before ordering parts. Retrofit brackets, such as the Uflex top bracket, are designed specifically to upgrade older systems without replacing the entire trim panel.
Check fasteners and pins for wear regularly, especially if the trim tabs are used in highly variable conditions — constant motion wears out parts faster than more occasional use. Lubricate moving joints with the manufacturer’s recommended grease to prevent corrosion from salt water during the season.
Consider replacing the entire fastener set at once if an individual part is already clearly worn out — other parts of the same age are likely nearing the end of their service life, and a one-time replacement will save labor compared to repeated individual repairs.
If necessary, seek advice on identifying the correct bracket if the make or model of the trim level is unclear — installing the wrong bracket can cause extra stress and premature wear on the system.
Compare the material of the bracket according to the operating environment of your boat — stainless steel or anodized aluminum are best suited to continuous exposure to seawater.
Always check the tightness of the fastener at the beginning of the operating season before the first longer ride to ensure safety.
Ask for advice on choosing the right mount if the make or model of your trim level differs from the most common options.
Compare the ease of installation of the bracket if you do the maintenance yourself without the help of a professional at home port.
Compare the delivery contents of the bracket, as some kits include the necessary bolts and nuts already included.
