CNC Machined from high grade aluminum, our front bulkhead will greatly increase the durability of the front suspension of your XXX-SCT. We also added set screws for holding the hinge-pins in place, so you do not loose the hinge-pins if the e-clips ever popped off during a race. This also prevent the hinge-pins from rotating inside the bulkhead and wearing down the bulkhead. The setscrew holes are at 45 deg. angle so it keeps the bottom of the chassis smooth and allows for the skid plate to be installed.
