• PERFECT FIT & ENHANCED SAFETY: Specifically designed for trailers with a Gross Axle Weight Rating (GAWR) of 5000 to 8500 lbs. This air helper spring kit provides critical supplemental support to your trailer's main leaf springs, preventing dangerous sagging, improving stability, and ensuring safer towing experiences, especially when carrying heavy loads.
• PRECISE MODEL & DURABLE CONSTRUCTION: Model TSS-107-47 (Left/Right). Crafted from high-strength, rubber-reinforced materials, these air springs are built to withstand extreme pressure, road debris, and harsh weather conditions. The robust design ensures long-lasting performance and reliable load-bearing capacity for years to come.
• SUPERIOR LOAD SUPPORT & LEVELING: Instantly increase your trailer's load-carrying capacity. By simply adjusting the air pressure, you can effortlessly level your trailer, compensate for uneven weight distribution, and eliminate bottoming out.
• EASY INSTALLATION: The kit is designed for a hassle-free "spring-over" configuration installation on the trailer axle. No welding or complex modifications are required. It comes with necessary hardware, allowing most users with basic mechanical skills to complete the installation in about 1-2 hours per axle.
• HOW IT WORKS: ADAPTIVE SUPPORT SYSTEM: The air helper springs work in tandem with your existing leaf springs. When inflated, the air bags absorb road shocks and share the load, reducing stress on the main springs.
