A rear suspension system for a land vehicle comprising a single generally centrally mounted structure in a middle portion of the rear suspension system. The suspension system comprises a pair of inclined primary suspension means, and a pair of inclined primary oscillating arms for pivotally connected to a pair of laterally spaced longitudinal slides at an underside area of the chassis of the land vehicle. Each of the primary oscillating arms comprise a distal end, which are further coupled to a horizontal bar adjacent a distal end of the primary suspension means, such as a shock absorber, and a proximal end which are individually mounted a horizontal bar adjacent a front end of the primary suspension means at an underside portion of the chassis. The suspension system further comprises a Weight Transfer Dynamic Compensator for raising a front tip portion of the longitudinal slides each time there is a transfer of weight in the vehicle. The Weight Transfer Dynamic Compensator is beneficial during acceleration and cornering of the vehicle by allowing the front end of the vehicle to remain close to the ground, thereby providing improved traction and control of the vehicle.

[ What is claimed:] [1.] A suspension assembly for a snowmobile vehicle comprising:two substantially parallel and spaced apart elongated slide members defining a longitudinal axis, connected together with transversally mounted bridge members, each said slide member having a first curved ending portion and a second ending portion for connection of ending wheels,two substantially parallel elongated pivoting arms, each having a first end pivotally connected on said slide members at a first connection point spaced apart said first ending portion and a second end adapted for connection to a vehicle chassis; a first transversal rod, adapted for connection to the vehicle chassis, resiliently connected to said slide members and pivotally connected to said pivoting arms through a fourth transversal rod disposed between the pivoting arms between said second end and said first end; said fourth rod being pivotally connected to the curved portion of the slide members through a fifth horizontal rod disposed between said curved portions of said slide members.
