Hello Darryl,
Thank you for including the weight of your trailer, especially the tongue weight.
You will want the SumoSprings Solo Custom Helper Springs - Rear Axle # SS68DR. The # SS68DR has a weight capacity of 1,400 pounds, and the # SS78DR has a capacity of 1,800. The 1,400 is more than enough for your 380 pound tongue weight.
What kind of trailer is it? Something for work, or something for fun?
