The seat is a working part of the chassis on a racing kart. Altering the stiffness of the seat and its mounting can have a dramatic effect on handling.
One end of this plated steel 3/4" OD tubular strut has two 8mm (5/16") bolt holes. The other end has a 4-bolt flange to clamp over a 1 1/8" - 1 1/4" (28 to 32mm) frame side rail. The bolt holes are located 9 3/4" and 10 3/4" from the surface of the tube. Sold individually.
We also offer a Racing Kart Seat Strut for Chassis Crossmembers (Part No. 9930), with the clamp flange turned sideways to clamp on a tube running across the chassis.
