Rubber crossbeam protectors and trailer motor locks are designed for single hydraulic cylinder trim and tilt system outboard engines, compatible with most marine engines; please check your engine model before purchasing You will receive 1 piece 5-inch (approximately 13.2 cm) crossbar protector support and 2 piece 4-inch (approximately 10.2 cm) outboard motor locks that keep the engine tilted and stable, while the crossbar protector absorbs shock, providing double safety for the trailer Outboard crossbar protection brackets and motor locks can be quickly and easily mounted around trimming and tilting mechanisms, helping to protect your outboard and minimize stress on boat crossbars, which is necessary for rough roads. Our ship beam protective bracket and motor lock, made of high-density rubber, can resist high temperature corrosion and provide you with a long service life. This marine motor cross beam support component set prevents cross beam stress and cracking by redistributing motor weight to the trailer frame, reduces long-term hull rupture, minimizes vibration and engine internal wear, enjoys smoother traction and extends motor life The boat crossbeam protection support and lock can lift the motor to avoid hitting ground collisions, curbs and potholes, perfect for long-distance portation, gravel roads and sudden stops without failure. Reduce the pressure of tilting or trimming hydraulics by locking the motor angle. Prevent fluid leakage and premature component failure.: Material: Rubber Color: Black Package Contents: 1 x Crossbeam Protection Bracket 2 x Trailer Motor Locks Only the above package content, other products are not included.
