RCM excavator thumb kits are made to be a great value while offering: incredible quality, design, and durability. We are continually striving to produce the best quality thumbs possible. This is a complete thumb kit with everything you need to install on a machine. We include a 30 day return policy and 1 year warranty on all thumb kits. Instructions included with all orders.
Our thumbs and hydraulic cylinders are custom designed and manufactured in the USA. Our cylinders are high quality with a stronger internal rod to prevent bending. Made for 3500 psi, tested at 3000 psi. Cylinder stroke distance = 19’’. Designed for maximum possible stroke, the thumb folds up and out of the way when not in use, under 12’’. Less than even factory designed models. Utilizing side ports allows for the hoses to connect out of the way of use. Thumb length = 27’’ Thumb Width = 9.25’’ between the bosses.
These excavator thumb kits are made to last! Composed of two 3⁄4'' thick AR400 steel tines. Our tines will hold up too many years of wear and tear. AR400 is a much stronger and harder steel than A36 steel. Many fabricators only use A36 Steel, causing them to wear down quickly. The main pin is from 4140 Heat treated, high strength steel. This high strength pin will last, decreasing chances of: complications, breaks, wear, and tear. Not center drilled. Grease fittings are provided at all pivoting locations. Fittings are protected from material collision that may occur during use. Due to increased chances of the main pin breaking, we do not center drill the main pins for grease fittings. Instead, grease fittings are located at the thumbs pivot points.
RCM is a family owned and run business; we have been producing thumbs for over 10 years. Due to our designs, fabrication quality, and customer service, we have many happy customers. If you are interested in a thumb for a different machine or have any other questions; feel free to contact us.
