   BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates generally to motor vehicle suspension and, more specifically, to a light truck support lift which is positioned between the existing leaf spring eyelet and the truck body which incorporates fastener adjustable members for varying the height of the lift. 
   2. Description of the Prior Art 
   There are other lift devices designed for motor vehicle suspensions. While these lift devices may be suitable for the purposes for which they were designed, they would not be as suitable for the purposes of the present invention, as hereinafter described. 
   SUMMARY OF THE PRESENT INVENTION 
   A primary object of the present invention is to provide a motor vehicle suspension lift device that is inserted between the leaf spring and the truck body. 
   Another object of the present invention is to provide a motor vehicle suspension lift device comprising a pair of mating supports having a plurality of apertures therethrough for placing fasteners therein. 
   Yet another object of the present invention is to provide a motor vehicle suspension lift device comprising a pair of mating supports wherein a first pair comprises planar bar stock having extending wall portions forming a substantially U-shape. 
   Still yet another object of the present invention is to provide a motor vehicle suspension lift device comprising a pair of mating supports which are substantially planar and dimensioned to reside within the walls of the first pair of supports. 
   Another object of the present invention is to provide a motor vehicle suspension lift device comprising a pair of mating supports having a plurality of coaligned apertures whereby said pair of supports can be releasably fastened one to the other. 
   Yet another object of the present invention is to provide a motor vehicle suspension lift device having a bushing positionable between the top most members and fastenable to the vehicle body. 
   An additional object of the present invention is to provide one or more spacers for adjusting the fit of the bushing. 
   Still yet another object of the present invention is to provide a motor vehicle suspension lift device wherein the bottom most apertures of the lift support are spaced apart to receive the spring eyelet bushing. 
   Additional objects of the present invention will appear as the description proceeds. 
   The present invention overcomes the shortcomings of the prior art by providing a light truck support lift which is positioned between the existing leaf spring eyelet and the truck body which incorporates fastener adjustable members for varying the height of the lift. 
   The foregoing and other objects and advantages will appear from the description to follow. In the description reference is made to the accompanying drawings, which forms a part hereof, and in which is shown by way of illustration specific embodiments in which the invention may be practiced.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   The following discussion describes in detail one embodiment of the invention (and several variations of that embodiment). This discussion should not be construed, however, as limiting the invention to those particular embodiments, practitioners skilled in the art will recognize numerous other embodiments as well. For definition of the complete scope of the invention, the reader is directed to appended claims. 
     FIG. 1  is an illustrative view of prior art  20  and of the present invention  10 . The present invention is a lift support system for light trucks  10 , which is adjustable to elevate the rear of a light truck  22  or other such vehicle to a needed height depending on the demand of the user. The system comprises an upper chassis attachment assembly  12  that fastens to the chassis  16  and a lower leaf spring attachment assembly  14  that is secured to the leaf spring  18  of the suspension system to lift the bed of the vehicle. 
     FIG. 2  is a perspective detail view of the lift support system  10  for light trucks, which is adjustable to elevate the rear of a light truck to a needed height depending on the demand of the user. The present invention  10  provides a leaf spring attachment assembly  14  that is selectively attachable to a mating chassis attachment assembly  12 . The leaf spring attachment assembly  14  comprises a pair of substantially U-shaped receiving bars  26 . The chassis attachment assembly  12  comprises a bushing  24  with a pair of substantially flat, elongate extension bars  28  extending perpendicularly downward from the ends of their respective bushing  24 . The extension bars  28  are positioned and dimensioned to reside within the channels  30  defined by the U-shaped configuration of the receiving bars  26 . A plurality of coaligned fastening apertures  32  linearly disposed along the lengths of the receiving bars  26  and the extension bars  28  for receiving bolt  34  and nut  36  fasteners to adjoin the two assemblies together. The bushing  24  of the chassis attachment assembly  12  is bolted to the leaf spring bracket  38  integral with the chassis  16  and the receiving bars  26  of the leaf spring attachment assembly  18  are bolted to the eyelet  58  of the leaf spring  16 . 
     FIG. 3  is an orthographic view of the present invention  10 . Shown is the lift support system for light trucks  10  which is adjustable to elevate the rear of a light truck to a needed height depending on the demand of the user. The bushing  24  of the chassis attachment assembly  12  is retained within the leaf spring bracket  38  of the chassis  16  and the leaf spring attachment assembly  14  is fastened to the eyelet  58  of the leaf spring  18  with a bolt  34  placed through the selected fastener apertures  32 . 
     FIG. 4  is a rear view of the present invention  10 . Shown is the lift support system for light trucks  10  which is adjustable to elevate the rear of a light truck to a needed height depending on the demand of the user. The bushing  24  of the chassis attachment assembly  12  is retained within the leaf spring bracket  38  riveted  56  to the chassis  16  and the receiving bars  26  of the leaf spring attachment assembly  14  is fastened to the eyelet  58  of the leaf spring  18  with a bolt  34  placed through the selected fastener apertures  32  and secured thereto with a nut  36  and washer  40 . A plurality of spacers  42  of varying thicknesses are provided to adapt the length of the bushing  24  accordingly to the vehicle. 
     FIG. 5  is a top view of the present invention  10  showing the bushing  24  of the chassis attachment assembly  12  fastened to the leaf spring bracket  38  of the chassis with a bolt  34 , nut  36  and washer  40  assembly. The extension bars  28  are bolted on the side of the spacers  42  opposing the bushing  28   
     FIG. 6  is a view of the lift support system of the present invention  10 . Shown is a fully assembled chassis attachment assembly  12  and the receiving bars  26  of the mating leaf spring attachment assembly. The receiving bars  26  comprise a main plate  44  with sidewalls  46  depending from opposing edges thereof that form the channel to receive the extension bars  28  of the chassis attachment assembly  12 . Also shown are the fastener apertures  32  disposed in the main plate  44  of the receiving bar  26  and in the extension bar  28 . The alignment of the apertures  32  of the associated bars determine the length of the lift support  10  once bolted together. 
     FIG. 7  is a view of the present invention  10  demonstrating the relationship between the inner side  48  of the receiving bar  26  and the extension bar  28 . The sidewalls  46  depending from the main plate  44  define the channel  30  that receives the extension bar  28  therein and the overall length thereof is determined by the alignment of the fastener apertures  32 . 
     FIG. 8  is a perspective view of the present invention  10 . Shown is a fully assembled chassis attachment assembly  12  and the receiving bars  26  of the mating leaf spring attachment assembly.
