Expert Answers about Redline

  • Can a Trailer with Axles Under Leaf Springs Be Lifted Further
  • If you already have your axles mounted below the leaf springs the only way you can add height to a trailer is to go with taller hangers for the suspension. You would need to have the old suspension hangers cut off and new, taller ones welded on by a qualified professional welder. I have included a link to the hanger main page for you.

  • How to Determine Correct Grease Seals for 1959 Sea Breeze 5th Wheel Trailer
  • I don't have a reference guide to provide me with that information, but if you can get me the diameter of the inner hub bore and the diameter of the spindle surface where the seal rides, I can recommend a seal for you, if one's available. When the diameter of the hub bore and the seal journal surface of the spindle is measured, the dimension needs to be accurate to 3 decimal places, so using a digital caliper like # PTW80157 is recommended. I've provided photo for you showing these dimensions....

  • Replacement Leaf Springs For 1998 Dri Doc Boat Trailer
  • The best way to find the right leaf springs for your trailer is to measure the eye-to-eye dimension of a leaf spring you have. The spring needs to be removed from the trailer to get the best measurement. Keep in mind that the length of the leaf spring will probably be a little longer than a new leaf spring due to wear and weight on the springs over an extended period of time. We offer springs for 2,000-lb, 3,000-lb, and 3500-lb springs. If you have a double-eye leaf spring and have...

  • What is the Bolt Grade for Redline Wet Equalizer Bolt with Castle Nut 126A1
  • Items like the Redline Wet Equalizer Bolt with Castle Nut # 126A1 do not carry a formal grade rating according to my contact there. An item like this will have a rating sufficient for any application suited to its dimensions. In other words, in trailer suspension applications where it fits properly, it will be adequately rated.

  • Tandem Axle Hanger Kit Recommendation that has 5-3/4 inch Center Hangers
  • For a trailer suspension kit that comes with 5-3/4 inch equalizers you would want the part # AP233-H248 instead of the # APT5. Aside from that and the center hangers being slightly different to accommodate the different equalizers the kits are the same.

  • Leaf Springs, Hanger Kit, and U-Bolts for a 2 Inch Square Trailer Axle
  • Since you do not know the capacity of the trailer axle then you can't go by the capacity of the springs. If the axle is rated for 2,000 pounds and the springs for a 3,500 pound axle then you would still be limited to 2,000 pounds. If you have the inner and outer bearing numbers then that will help to determine what the likely axle capacity is. Since you want to replace the hangers as well as the springs then it doesn't matter which springs you choose. If the axle does end up having...

  • Roof Vent Recommendation for a Pleasant Valley Tear Trailer
  • For your small tear trailer I recommend a small, round 12 volt vent/fan, # VP-543SP. You may not have to move the light, it will limit the hole size needed, and the curved roof won't be a problem. The vent just needs to be connected to a 12 volt circuit for power and grounded to a clean metal surface. I have linked a video review of this vent for you.

  • Replacement Wheel Studs for Wheels on 2004 Timberlodge by Adventure Manufacturing
  • All 1/2-inch diameter drive-in wheel studs are shown on the linked page. The one nearest to your required dimensions (thank you for your included photo) is Kodiak # K12WB2. Overall length is slightly greater but most specs match up closely.

  • Can a Tandem Axle Trailer go to a Single Axle
  • If you are absolutely sure you wouldn't exceed the capacity of the one axle on your trailer you could get by with just one axle. You are going to have to move the good axle to where the center equalizer is currently at to ensure you get proper axle placement which ensures that your trailer tongue weight will be in the 10 to 15 percent of the total trailer weight range so that you don't have sway. For a single axle hanger kit you would need the part # APS1.

  • Replacement Slipper Spring for Boat Trailer 1000-lb Axle
  • Well-worn leaf springs can become elongated and actually measure longer than their length when new. It is not uncommon for a leaf spring to get as much as 3/4-inch to 1-inch longer from years of use. If your spring measures 25-1/4-inches long then chances are that when new it was indeed the 24-1/4-inch length of the Redline # WIC2. This 2-leaf spring is rated for 1000-lb trailer axles; you can check the sticker on your axle to confirm it's weight rating. This spring does indeed use a...

  • Replacement 2,200 lb Trailer Leaf Spring that is 25-1/4 inches Long
  • 25-1/4 inch leaf springs are a very common length. For a leaf spring that is rated for a 2,500 lb axle that is 25-1/4 inches long you would want the part # PR722. If instead you meant 2,200 lbs per spring you would want the # PR4 instead.

  • Does the 2-Piece Polypropylene Trailer Vent have to Be Installed Facing a Certain Direction
  • There isn't really a specific way that the 2-Piece Polypropylene Trailer Vent # HMAV2-AVT2 has to be mounted. You could mount it like in the pictures or in any other orientation. It's just that with the openings pointed down it is much less likely that rain water could get inside the trailer.

  • How to Determine the Capacity of 2 Inch Square Axle
  • Square axles can be tough to determine capacity since the same spindle can typically fit a range of axle capacities. With this being said the absolute best way to determine the capacity of your axle is to locate a plate/sticker on the axle itself or on the trailer. If this is not available we can take a few steps to try and narrow it down for you. 1) A 2 inch square axle using a 5 on 3-7/8 inch brake mounting flange is typical of 5,200, 6,000, and 7,000 lb axles. If you can provide the...

  • How to Determine Capacity of Square Axle
  • Square axle capacities are pretty hard to determine. Unlike round axles, they do not have set capacities based on their dimensions. Based on the bearings your hub looks like it's rated for 3,500 lbs. Most likely that would be the same rating as your axles.

  • Replacement Slipper Spring Recommendation to Replace 31 inch Long Spring
  • For a slipper spring that would work well for your application you would want the part # WID2. This is a 2k rated spring that is 30-1/4 inches long. This should be a much softer spring than what you have as it looks like your spring would be a higher capacity than this one.

  • Why Are Leaf Spring Bushings Narrower Than the Springs
  • The bushings aren't designed to extend past the edge of the spring. When the shackle bolts are tightened, they're not meant to be drawn down so tight that the spring hanger or shackle is in contact with the side of the spring eye. That's why the spring/shackle bolts will typically have the knurling on one end, so they're locked into place.

  • Trailer Lift Recommendation for a Trailer with Axles Over Springs
  • Aside from moving the axles below the leaf springs the only other way we recommend you lift a trailer is by installing taller spring hangers on the trailer frame. What you would need to do is measure the dimensions of your current hangers and then compare them to the hangers at the attached link and then go with ones that will give you the amount of lift you need.

  • Replacement Trailer Leaf Spring for 3,500 lb 25-1/2 inch Springs
  • When measuring to replace trailer leaf springs you want to measure them while they are unloaded. Since leaf springs tend to stretch as they flatten out over time going with a new spring slightly shorter in length is recommended. Since yours are 25-1/2 inches in length currently a 25-1/4 inch spring like you referenced would be ideal. The # PR4B would be perfect since it fits the length you would need and the weight capacity as it has a 3,500 lb capacity. Going with a taller shackle will...

  • Replacement Slipper Spring for a Sea-Doo Boat Trailer
  • On slipper spring # C-4 from the center of the bolt hole to the apex of the curve on the slipper it measures 26-1/4 inches. But to the internal part of the hook it measures 27-1/2 inches. So if you measure one of your springs and the measurements match up then spring # C-4 could work. When measuring an existing spring you will need to have the weight off of it by either removing the spring or jacking up one side of the trailer. While you are under there check for any loose or worn hardware....

  • Raising the Height of a 2015 Shasta Airflyte 16 Reissue Trailer
  • This is the first time I have heard of this issue but if a 5-leaf spring is the fix then we may have something that will work depending on the measurements you will need. When measuring springs you will need to have the weight off of them by either removing a spring or jacking up one side of the trailer so no weight is on that one side. Spring # PR5 is the only 5-leaf double-eye spring that we carry. It measures 25-1/4 inches from spring eye center to spring eye center and 3 inches from...

  • Where to Measure 3 Axle Trailer to Determine Weight Capacity
  • Sounds like you are trying to figure out the weight capacity for your 3 axle trailer. It is nearly impossible to determine leaf spring capacity based on dimensions. But you can determine axle capacity by measuring. Since your axles are 3 inches in diameter it would seem that they are 6k to 7.2k rated axles. For suspension enhancement to help support your current setup you would want the Timbren Trailer Suspension Enhancement # TTRA1032 or you would need to replace your current springs...

  • Ways to Identify Axle Capacity of a Trailer
  • If you check the plate of the trailer that has the VIN and weight ratings for the trailer there should be axle ratings listed as well. This plate is often near the coupler of the trailer on the frame. Typically you can tell the capacity of a trailer axle by the diameter of it. Typical Axle Diameters Based on Axle Capacity - 1,000-lb - 2,000-lb Axles: 1-1/2 inch - 1-3/4 inch diameter - 3,500-lb Axles: 2-3/8 inch diameter - 6,000-lb - 7,200-lb Axles: 3 inch diameter - 8,000-lb...

  • Plastic Fender Recommendation for Trailer and ST205/75-15 Load Range Tires
  • It looks like the Single Axle Trailer Fenders # PF11X35W-2 that you referenced would be your best option. But before you order it check out the dimensions for it in the picture that I attached so that you can compare them to your trailer. For a Load Range C tire in the ST205/75-15 size you would want the part # AM10244. This is a radial tire that would work great for you.

  • How to Measure a Trailer Spindle to Determine What Hub Could Replace
  • You are on the right track by measuring dimensions of the spindle with a dial caliper, but to determine which hub could potentially fit your spindle you need to measure it where the bearings and seal rides. See pic to see where to measure. If you can get back to me with that info I will be able to determine if there is a hub that could fit.

  • Should Equalizer Sit Level on Tandem Axle 5 Ton Trailer
  • For the most part the axles/equalizer should be level provided the tires and trailer are level. From the picture that you provided, the angle of the equalizer isn't something that I would be concerned about since the rear tires are up on a piece of lumber and not sitting level.

  • Ways to Raise the Suspension of a Trailer
  • There are ways to raise a trailer's suspension, but moving the shackle straps so that they are underneath the equalizer would not be a recommended method. The most common way is to move the axles above the leaf springs if they are currently under them, or to get longer suspension hangers. The diameter of your trailer axle will determine the size of the parts that you will need to order. If your axle is 3 inches diameter, the Dexter Trailer Springs Over-Under Conversion Kit, # K71-385-00,...

  • Is It Possible to Move Square Axles Below Leaf Springs
  • Based on the picture you submitted that shows a square axle welded to a mount which is then welded to a leaf spring you would need to have someone qualified use a cutting torch to remove the mount from the spring so that you could then use a u-bolt style of mounting kit to attach the spring on top of the axle. To do this you will need to know the dimensions of the axle. We have kits for square axles that range from 1-1/2 inch square axles up to 2 inch axles. Once you determine the size...

  • Do Trailer Bearings Fit Tight To the Spindle they Install On
  • Bearings fit pretty tight onto spindles. There basically should be no play at all between the inner portion of the bearing and the spindle. They don't fit so tight that they would have to be pressed on, but they sometimes can be tight enough that they require a bit of effort to get them totally slid on. Check out the install video I attached for more info on how bearings install.
