The all new PRO4X performance ultra narrow lipo chassis for the HPI PRO4!

- 2.3mm thick quasi weave carbon fiber chassis for improved steering and rear traction. Go into corners deeper and power out stronger.

- Only 88mm wide at the main chassis section to better utilize lower ride heights for more aggressive cornering.

- Includes carbon fiber battery hold in cups. Adjustable slider style allows the perfect fit for most batteries and does not interfere with the battery tape.

$84.95 MSRP, HPI PRO4 required.
