Used kit to completely redo goose neck. Worked great I like the zerk fittings. I did drill and tap the bars for zerks as well

Very glad each item was individually packaged because the box was busted open in two places (not the fault of the company) and even the bigger parts could have come out. All parts were in the box and everything worked as it was intended. Great communication from company about shipping.

Ask the Experts about this Redline Trailer Leaf Spring Suspension



  • Suspension on Instigator 3-Axle Boat Trailer Hits Frame
    I did some research on your trailer and also read a few bad reviews from customers with the company. Since I do not have the trailer in-front of me, there is no way for me to say for certain that the suspension is mounted incorrectly. But, it definitely should not be hitting the frame under normal use. I would recommend having a trailer professional checkout your trailer to see if everything is mounted correctly. If you bought the trailer new, you may be able to contact the company and...

  • Can Triple Axle Hanger kit part # APTT5 be Used on Trailer with 7k Axles
    Yes, the Triple Axle Hanger kit part # APTT5 would work great on your trailer that has 7k axles as it was designed for use on axles up to 7k.

  • Differences Between Triple Axle Hanger Kits APTT1, APTT3, and APTT5
    The differences are the dimensions of the hangers and equalizers of the three kits. The # APTT1 uses totally straight equalizers and taller center hangers. The # APTT3 uses more traditional sized equalizers and center and outside hangers that differ in size slightly. The part # APTT5 uses a standard sized equalizer and hangers that are all the same height. The part # APTT3 is the one that is the most commonly used. It would be my recommendation for your trailer.

  • Recommended Hanger Kit for a Triple-Axle Trailer Hanger Kit for Double-Eye Springs
    The recommended hanger kit for a Triple-Axle Trailer Hanger Kit for Double-Eye Springs is part # APTT1. This kit is designed to work on axles with capacities of 2,000 to 7,000 pounds. If your mobile home trailer axle is within this weight capacity this kit should work for you.

  • Can I Lift The Rear Of My Trailer If My Axles Are Already Overslung
    Your only option is to go with taller suspension spring hangers since your axles are already overslung. (Your leaf springs are on top of your axles.) Due to this, you cannot just raise the rear of your trailer, in a safe manner. For example, you will be able to raise the height of your trailer with the Triple-Axle Trailer Hanger Kit for Double-Eye Springs - 2-1/2" Front/Rear, 5-7/16" Center, part # APTT1, if your hangers are shorter than 2-1/2". If you provide me with the measurements of...

  • Determining Where To Place 3rd Axle To Upgrade Tandem Axle Trailer W/ 7000lb Axles
    I would be happy to help, but adding a third axle is not quite as simple as just placing it in front or behind your current two 7000lb axles. You will need to remove the axles and find the correct location for each axle by following the included help article. Since your trailer will have triple axles you will need to measure from the tongue to the center of the center axle. Next your best bet is replacing your hangers with a new kit as they will be in the incorrect location. I recommend...
