1. A tie-plate comprising: a lower mounting flange that is removably attachable to an inboard facing surface of a first frame hanger and to an inboard facing surface of a second frame hanger, wherein the first and second frame hangers are attachable to an outboard facing surface of a longitudinal frame rail of a vehicle,wherein the lower mounting flange includes a first set of attachment holes that correspond to a set of attachment holes through the inboard facing surface of the first frame hanger,wherein the lower mounting flange includes a second set of attachment holes that correspond to a set of attachment holes through the inboard facing surface of the second frame hanger,an extending member having a first end that extends at an angle from the lower mounting flange;and an upper mounting flange extending from a second end of the extending member, wherein the upper mounting flange has one or more mounting holes adapted for attachment of the tie-plate to an undercarriage of a vehicle at a position that is located inboard of the outboard facing surface of the longitudinal frame rail of the vehicle. 2. The tie-plate of claim 1, wherein the first set of attachment holes comprises a plurality of attachment holes, andwherein the second set of attachment holes comprises a plurality of attachment holes. 3. The tie-plate of claim 1, wherein the first set of attachment holes comprises only one attachment hole, andwherein the second set of attachment holes comprises only one attachment hole. 4. The tie-plate of claim 1, wherein the lower mounting flange is generally perpendicular to the upper mounting flange. 5. The tie-plate of claim 1, wherein the first set of attachment holes on the lower mounting flange are oblong. 6. The tie-plate of claim 1, wherein the extending member extends at an angle of between 60 and 70 degrees from the lower mounting flange. 7. The tie-plate of claim 1, wherein the lower mounting flange includes four attachment holes and the upper mounting flange includes two mounting holes. 8. The tie-plate of claim 7, wherein the mounting holes on the upper mounting flange are adapted to correspond to mounting holes positioned on an extension of a vehicle frame rail. 9. The tie-plate of claim 8, wherein the mounting holes of the upper mounting flange are also adapted to correspond to mounting holes positioned on a cross member of a vehicle chassis. 10. A tie-plate comprising: a lower mounting flange that is removably attachable to (i) a first frame hanger that comprises a first set of frame-hanger-to-frame-rail attachment holes, and (ii) a second frame hanger that comprises a second set of frame-hanger-to-frame-rail attachment holes,wherein the lower mounting flange includes a first set of attachment holes that correspond to a set of tie-plate attachment holes at the first frame hanger,wherein the lower mounting flange includes a second set of attachment holes that correspond to a set of tie-plate attachment holes at the second frame hanger, andwherein the lower mounting flange is attachable to the first frame hanger and the second frame hanger such that the lower mounting flange is attached at a position below the first set of frame-hanger-to-frame-rail attachment holes and below the second set of frame-hanger-to-frame-rail attachment holes;an extending member that extends inwardly and upwardly from the lower mounting flange; andan upper mounting flange extending from the extending member, the upper mounting flange having one or more mounting holes adapted for attachment of the tie-plate to an undercarriage of a vehicle. 11. The tie-plate of claim 10, wherein the mounting holes of the upper mounting flange are also adapted to correspond to mounting holes positioned on a cross member of a vehicle chassis. 12. A suspension assembly comprising: a first frame hanger that comprises a first set of one or more attachment holes and an opening adapted to receive one or more spring elements;a second frame hanger that comprises a second set of one or more attachment holes and an opening adapted to receive one or more spring elements;a tie-plate that comprises a lower mounting flange having a third set of attachment holes and a fourth set of attachment holes,wherein one or more first fasteners may be inserted through the first set of attachment holes and the third set of attachment holes to fasten the tie-plate to the first frame hanger, andwherein one or more second fasteners may be inserted through the second set of attachment holes and the fourth set of attachment holes to fasten the tie plate to the second frame hanger;an extending member that extends inwardly and upwardly from the lower mounting flange;and an upper mounting flange extending from the extending member, the upper mounting flange having one or more mounting holes adapted for attachment of the tie-plate to an undercarriage of a vehicle. 13. The suspension assembly of claim 12, wherein the first frame hanger further includes a first set of frame-hanger-to-frame-rail attachment holes, andwherein the second frame hanger further includes a second set of frame-hanger-to-frame-rail attachment holes. 14. The suspension assembly of claim 12, wherein the opening in the first frame hanger is defined, at least in part, by a first side wall,wherein the first side wall includes a first pocket to retain a first end of a first shear spring,wherein the opening in the first frame hanger is defined, at least in part, by a second side wall,wherein the second side wall includes a second pocket to retain a first end of a second shear spring,wherein the lower mounting flange of the first tie-plate attaches to the first frame hanger such that a plane containing a center line of the first pocket and a center line of the second pocket passes through the lower mounting flange,wherein the plane is parallel or substantially parallel to a bottom of the first frame hanger, andwherein the center line of the first pocket substantially coincides with the center line of the second pocket. 15. The suspension assembly of claim 12, wherein the first fasteners and the second fasteners are selected from the group consisting of (i) bolts and nuts, (ii) huck fasteners, (iii) rivets, (iv) screws, and (v) thread-forming screws. 16. The suspension assembly of claim 12, wherein the lower mounting flange is generally perpendicular to the upper mounting flange. 17.
