DESCRIPTION
The MMP-4 is equipped with a 6,000 lb (2,725
kg) rated single axle utilizing a double eye leaf
spring suspension. The springs are attached to
the frame by welded spring hangers. The axle
is attached to the springs by U-bolts with weld
on axle mounts. Mounted to the axle hubs by 8
lug nuts are load range E tire and rim
assemblies. Each tire and rim assembly is
protected by a steel fender that contains a front
amber marker lamp and rear red marker lamp
assembly. Current production models are not
equipped with brakes.
