The L-pin from Fastway Trailer Products is built to keep your spring arms securely connected to your trailer frame, giving you confidence and safety on the road. Designed for a snug, reliable fit, there are two versions to match your setup—one for the 4.5K trunnion model and another that works with both round bar and trunnion-style e2 hitches in the 6K, 8K, 10K, and 12K weight ratings. Whether you’re hauling gear for work or heading out on a weekend trip, these L-pins make sure your hitch stays locked in place, mile after mile.
