Description

Restore dependable parking and emergency braking performance on your commercial rig with the CPS / Max Type 30/30 Long Stroke Air Brake Piggyback Kit (Part # 3030PBKLS). Engineered specifically for heavy-duty semi-trucks, tractors, and trailers equipped with S-cam air brake systems, this 3-inch long-stroke piggyback unit replaces worn spring brake chambers without needing to replace the entire service housing. Built with a heavy-duty corrosion-resistant housing, a sealed center section to block out dust and moisture, and a zinc-finished clamp band, it delivers consistent clamping pressure and extended service life under harsh road conditions. Every kit comes complete with a replacement diaphragm and mounting clamp hardware for a fast, straightforward installation that minimizes costly fleet downtime. [1, 2, 3, 4, 5, 6, 7]
