Feature
Ideal for many skid-steer loader applications
No back head charging required
CD designed side bolt threads provide even load distribution and greater surface contact between the nut and bolt reducing the chances of thru-bolt failure
Increased front head wall thickness for added service life
An increase in back head pressure results in a 25% greater impact on energy
