The QA1 5Q series circle-track rebuildable steel twin-tube shock six-pack delivers rebound-adjustable damping intended for oval and circle-track race use. Laser-engraved, black-anodized closure nuts keep serial numbers and valving readable at the track; gland relief cuts and a hyper-screw port make filling and bleeding simple. Two-piece bodies, slip-fit compression tubes and upgraded seal kits let racers re-valve and rebuild quickly with basic tools while reducing leak risk under high-rebound conditions.
