CNC-machined LEFT rear bulkhead for XRAY X1219 made from premium extra-strong Swiss 7075 T6 aluminum, black coated for long life and stylish look. Strategically machined for reduced weight while retaining strength. The intelligent pod design allows for super-easy motor top access, accommodating all brushless motors. The aluminum bulkheads allow for very quick & easy ride height adjustment; no more hassle to dismantle the car to change the rear ride height! The included ride height shims are inserted between the bulkhead and upper bulkhead clamp to alter the ride height. Smart & easy. The new method for ride height adjustment allows ultra-fine adjustment by 0.25mm increments, in comparison to the previous 0.5mm increments using eccentric bushings. Must be used with right rear bulkhead #373016.
