Heavy duty trailing arm suspension system

A heavy duty suspension system comprising:

• a frame;
• a pair of spaced apart trailing arms each including a forward portion pivotally supported by said frame and extending longitudinally to a rearward portion;
• an axle having opposing end portions pivotally supported respectively on said trailing arms;
• V-rod having first and second spaced apart ends extending to a common third end with said first and second ends attached to one of said frame and said axle and said third end attached to the other of said frame and said axle, said V-rod providing lateral stability and defining a pinion angle with said trailing arms, wherein said axle is movable between first and second positions with said pinion angle constant between said first and second positions.
