FAQ
Q1: Is the 3600AX suitable for steer axles or drive axles?
A: The 3600AX is primarily designed for rear drive axles and trailer axles that utilize a 16.5" x 7" brake shoe. For steer axles, please verify the required width, as they often use 5" or 6" drums.
Q2: What is the benefit of the "AX" suffix?
A: The "AX" typically denotes an "Extra-Heavy" or "Advanced Performance" casting design, optimized for better heat absorption compared to standard 3600A models.
Q3: How do you handle shipping for such heavy components?
A: We provide secure palletized shipping for bulk orders. Individual units are protected with moisture-proof wrapping to ensure they arrive at your shop in perfect condition.
