Reese has combined the best of the features from all of our weight distributing kits to create the High-Performance Trunnion Kit. It includes a head design with superior strength and easy adjustment. The head includes a forged raised ball platform and forged Trunnion mounts. The channel of the head utilizes our "serrated washer" design. The serrated washers make it easier to dial in the set up of the High-Performance Weight Distributing Kit. In addition to the changes in the head, the High-Performance Weight Distributing Kit includes the highest rated spring bars per class in the industry. They also feature an integrated cam for easy set up with the optional Dual Cam High-Performance Sway Control. Other features include 9-link chains for easier set up on larger trailer frames and innovative snap-up brackets designed for superior strength and durability.Pit Stop USA offers Reese Snap-up Bracket Package (Sold Each) 21501 at low everyday prices.
