CNC-machined LEFT back bulkhead for XRAY X1219 made from premium extra-strong Swiss 7075 T6 aluminum, black colored coated for very long life and trendy appearance. Strategically machined for paid off weight while keeping energy. The smart pod design permits super-easy motor top access, accommodating all brushless motors. The aluminum bulkheads permit very quick & simple ride height adjustment; forget about hassle to dismantle the car to improve the rear ride height! The included trip height shims are inserted involving the bulkhead and upper bulkhead clamp to change the ride height. Smart & easy. The new method for ride height modification allows ultra-fine adjustment by 0.25mm increments, compared to the previous 0.5mm increments using eccentric bushings. Must be used with right backside bulkhead #373016.
