Expert Answers about Trailer Suspension

• Correct Spring Position on a Dual Axle Boat Trailer with Slipper Springs
• You will want to get it set up correctly because there could be some problems down the road. You may not have to turn the axle around but you will definitely want to make it so the front spring slipper is pointed towards the rear. I have included a picture for reference. You will need to make sure that the front hangers are the proper height once the springs are turned around to allow for the correct amount of travel. You want the distance from the top of the axle to the bottom of the trailer

• Amount of Spring Deflection of Timbren Alxe-Less Suspension # A20RS440
• You are correct, the Aeon spring does indeed function as a dampener, and should not need additional dampening. Each unit is rated at a 1000 lb capacity, so two sets or four units would provide a 4000 lb capacity. The 2-5/8 inch dimension shown is the static position, but this exact dimension will depend on the construction of your trailer and how heavy it is. The engineering folks at Timbren tell me that the springs are capable of 2-1/2 inches of travel or deflection.

• Can a Trailer with 5,200 Pound Axles Use 5,800 Pound Double-Eye Leaf Springs
• The failure of the leaf springs may be a result of another component in the system that has a problem and needs to be replaced. I recommend having a shop take a look at the suspension components to make sure everything is working correctly and nothing else needs to be replaced. Adding higher capacity springs will give you a stiffer ride, but if the trailer manufacturer determines it permissible considering the problems you have had in the past, you should be able to use the larger springs.

• When Replacing Trailer Leaf Springs Go by the Weight Capacity of the Axle
• Yes, when replacing trailer springs, you will want to go by the listed axle capacity of the springs. It would be best to replace both springs at the same time. I also recommend that you check other suspension components before installing new springs. The suspension is only as strong as its weakest link. Even though the # PR5 spring is rated at 5,800 pounds, you will still need to stay within the capacity of the axle at 5,000 pounds and not overload the trailer. I have included a link to our F
