One New Aftermarket Replacement Equalizer Bar for Caterpillar (Cat) D6R / D6R Series II Track-Type Tractors
This aftermarket replacement equalizer bar (Bar As-Equalizer) is a structural undercarriage component for Caterpillar (Cat) D6R and D6R Series II track-type tractors (bulldozers). The equalizer bar connects the front ends of the left and right roller frames, maintaining balanced track tension, allowing the roller frames to flex independently over uneven terrain, and distributing machine weight evenly across both tracks. It is a critical part of the undercarriage assembly for smooth operation and minimizing wear on surrounding components.
