6. The track kit according to claim 4 , wherein the rear suspension locking device comprises a second connection for a vertically moveable portion of the rear suspension and a third connection for connecting the rear suspension locking device to the chassis.

7. The track kit according to claim 1 , wherein each track assembly comprises a front shock absorber operably connected to a front section of the intermediate support member and operably connectable to the chassis.

8. The track kit according to claim 1 , wherein the at least one swing arm comprises a front swing arm and a rear swing arm, the front swing arm is pivotably connected to a front section of the intermediate support member and pivotably connectable to the chassis, and the rear swing arm is pivotably connected to a rear section of the intermediate support member and pivotably connectable to the chassis.

9. The track kit according to claim 1 , comprising a support framework rigidly connectable to the chassis and to which the front idler wheel axle of each track assembly is rigidly connected and the at least one swing arm of each track assembly is pivotably connected.

10. The track kit according to claim 9 , wherein the front shock absorber of each track assembly is operably connected to the support framework, and/or a pinch wheel axle of each track assembly is rigidly connected to the support framework, and/or a shock connecting arm of each track assembly is pivotably connected to the support framework.

11. The track kit according to any one of the claims 9-10 , wherein the support framework is modular.

12. A vehicle comprising a track kit, vehicle comprising a chassis, a rear drive axle featuring two opposite wheel hub units and a rear suspension, and the track kit comprising two track assemblies, each track assembly comprises an endless track, a front idler wheel, an intermediate support member comprising at least one track engaging element, a rear idler wheel, a drive wheel, at least one swing arm and a shock absorber connecting assembly, wherein the endless track comprises an external side featuring ground lugs for ground engagement and an internal side featuring drive lugs for engagement with the drive wheel, and the internal side is circumferentially trained around and in contact with the front idler wheel, the at least one track engaging element, the rear idler wheel and the drive wheel; the drive wheel is connected to one of the wheel hub units; the front idler wheel is arranged at a level above the at least one track engaging element and comprises a front idler wheel axle rigidly connected to the chassis, such that the front idler wheel axle and the chassis are in a fixed relationship and not able to move relative to each other; the at least one swing arm is pivotably connected to the intermediate support member and pivotably connected to the chassis; the shock absorber connecting assembly is connected to the intermediate support member and operably connected to a lower end of a shock absorber having an upper end operably connected to the chassis.

13. A method of converting a wheel-drive vehicle to a belt-drive vehicle, the vehicle comprising a chassis, a rear drive axle featuring two opposite wheel hub units and a rear suspension, the method comprising the steps of:

providing a track kit comprising two track assemblies, each track assembly comprises an endless track, a front idler wheel, an intermediate support member comprising at least one track engaging element, a rear idler wheel, a drive wheel, at least one swing arm and a shock absorber connecting assembly, wherein the endless track comprises an external side featuring ground lugs for ground engagement and an internal side featuring drive lugs for engagement with the drive wheel, and the internal side is circumferentially trained around and in contact with the front idler wheel, the at least one track engaging element, the rear idler wheel and the drive wheel;
