SUNCOAST Superglide XLT Class Competition 28 - 1.80 Ratio COA-11125-180

The Coan Racing COA-11125-180 Superglide XLT Class Competition 28″ Transmission is a finely engineered, full-featured racing gearbox designed to meet the demands of serious Powerglide competitors. Built around a lightweight aluminum hub and Xtra‑Lite clutch drum, this unit significantly reduces rotating mass without sacrificing strength, allowing for faster throttle response and more responsive launches. It includes a low‑volume pump and 300M alloy input shaft for precise hydraulic performance and robust drivetrain integration. Internally, the transmission features an aluminum planetary carrier and Maximum Duty straight‑cut gears to deliver reliable, high-torque handling while maintaining smooth gear changes. The assembly is finished with a bolt-on alloy output shaft, fabricated deep pan for increased fluid capacity, and a 1.80 final drive ratio for optimal power delivery. A brake and reverse lockout system is incorporated, giving drivers confident, intentional launch control by preventing unwanted reverse engagement. Housed in a Reid one-piece case with roller-bearing tailhousing, the COA-11125-180 installs directly into Powerglide applications without modification. In sum, this transmission offers a thoughtfully balanced package of lightweight construction, performance-focused components, and drag-strip-ready control, making it a compelling choice for bracket racers and high-performance street/strip builds seeking precision and consistency.
