Expert Answers about Redline

  • Can a 4 Inch Bumper Strip be Used in Place of One that Sticks Out 3 Inches
  • The Pre-drilled round rubber bumper # D4-96 is going to stick out a little further than the old bumper you have but it will still work. The length would have to be trimmed down since the new one is 96 inches. The mounting holes are spaced 11 inches apart on center on the new one as well so it will work on your trailer.

  • Availability of Trailer Wheels that have a 5 on 4-3/4 Inch Bolt Pattern
  • If the center to center distance from one lug hole to the next is 2-3/4 inches then that does indicate a 5 on 4-3/4 inch bolt pattern. We have 2 trailer wheels that use this pattern. First is taskmaster wheel # TTW550547WS1 which is a 15 x 5 inch wheel with a negative offset of 0.31 inches. The pilot hole is 3.31 inches in diameter. Second is # WHi156-5475WS which is a 15 x 6 inch wheel with no offset. Its center hole is 3.19 inches in diameter. If the bolt pattern, size, and center...

  • Choosing Replacement Double-Eye Leaf Springs for StartCraft Pop-Up Trailer
  • You can change out your springs to higher-rated ones but that will not increase the trailer's weight carrying capacity. It will likely give you a stiffer ride, which you may or may not prefer. Chances are good that your trailer spring broke because it was 10-years old and brittle. You'll want to replace both springs to ensure the trailer tracks correctly. We do offer a 6-leaf 26-inch spring rated for 4500-lb axles, part # PR626, but as you noted your springs have probably become elongated...

  • 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.

  • Will 10 x 2-1/4 Inch Trailer Brake Shoe Pads Part BP04-095 Fit 10-Inch Nev-R Adjust Brake Assembly
  • Thanks for sending us a picture! The 10 x 2-1/4 inch trailer brake shoe pads part # BP04-095 you referenced only works with the manual adjust brake assembly. What you need is the left hand shoe lining # K71-681 and/or right hand shoe lining # K71-682 to fit the Dexter 10-inch Nev-R adjust brake assemblies. What I recommend instead of buying the replacement shoe liners, is replacing the entire brake assembly with part # 23-469 (right hand) or # 23-468 (left hand). The reason is because...

  • Hanger Spacing Recommendation When Installing Trailer Suspension
  • When installing trailer suspension you will need to completely mock up the axle and adjust the spring hangers accordingly. The measurements you listed from the chart are a good starting point, but due the variance in leaf springs and hangers and shackles can vary where they will perform best. The drawing on the chart shows a suspension when the load is placed on the suspension. The best way to install your system is to put the suspension all together and clamp it in place with the rear...

  • U-Bolts and U-Bolt Plate Recommendation for Installing Leaf Springs on a 1-1/2 in Square Axle
  • If what you really need is a new axle you can go to a local trailer shop to you and have them custom order you the exact specs you need for a trailer axle. But to attach springs to your 1-1/2 inch square axle you would want the mount plate part # 115983 and then for U-bolts part # Sp01-120. I attached review videos for both products.
