The GKTECH Z33 350Z/Z34 370z gearbox cross member for S13/S14 has been designed as a bolt on solution when fitting these gearboxes to an S chassis when running either an SR20/KA24 motor. The gearbox cross member has been designed to use an OEM S13/S14 gearbox mount such as our polyurethane/ solid mount that we also make. - 0.23' (6mm) steel plate, laser cut and press bent in Australia. - CAD designed - 0.78' (20mm) of adjustment to suit modified setups - Weighs 2.16 pounds (980grams) NOTE: Fitment is based on running an SR20 or KA24. If you're running an engine that sits further back then the cross member most likely won't work.
