GROVE Wheels and Brakes are precision engineered and manufactured to provide the highest quality and performance in the aircraft industry. GROVE wheels are manufactured in both aluminum and magnesium.  Aluminum wheels are more corrosion resistant than magnesium, are less expensive, but weigh more.  Both have the same strength and performance ratings. They are offered in sets (kits) in different sizes to comply with tire and axle sizes and static load ratings to match  the static aircraft gross weight on each wheel. GROVE brakes are offered for different braking torques, a function of the hydraulic system pressure and total caliper piston area, and with different kinetic energy capabilities. Aircraft with oversized tires or with a larger than normal engine should consider brake calipers with more or larger pistons. Different brake discs offered absorb the heat energy developed during braking.

Please refer to the Product Description section and the supplied documentation for additional information.
