I placed two different orders lately and the service and products were excellent. I comparison shopped in my local auto store and the price was just about twice the etrailor pricing.

  • 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...

  • Availability of Jeep Style Fender Measuring 10 Inch Wide x 36 Inch Long x 19-1/4 Inch Tall
  • The closest Jeep style fender we are going to have is trailer fender part # J101936. This fender is for single-axle trailers with 13" - 15" diameter wheels and measures 10" wide x 36" long x 19-1/4" tall. For an aluminum tread plate fender see # CE18041ATB. I have included a video review of this fender for you to check out.

  • Dimensions of the Brake Mounting Flange # 4-44-1
  • I went and pulled a Brake Mounting Flange # 4-44-1 from our warehouse to measure it for you and found that from the center of the studs to the inside edge of the center hole it measures 1/2 of an inch and then from the center of the top bolt down to the center of the hole it measures 2 inches.

  • 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...

  • Trailer Door Hook and Keeper are Not Lined Up Properly on a Outback Enclosed Trailer
  • So when you open the door and swing the hook part out to meet the keeper the door hits the fender before the 2 can reach each other? If that is the case then I would agree that somewhere along the line a mistake was made. The only hook and keeper we have is # 383400 and the hook is just 4 inches long. The best solution is to move the hook and/or keeper. It sounds like the screws used are Torx style or something similar. A hardware store should have the appropriate tool to remove and...

  • 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...

  • Galvanized Trailer Suspension Shackle Straps That Have Hole Spacing Close to 3-1/4-Inches Apart
  • It sounds like what you need is Redline part # 115208GALV. This galvanized shackle strap measures 4-3/8 x 1-1/4 overall and has two 9/16-inch bolt holes whose centers are 3-1/8-inches apart. These are sold as a single unit so you'll want to order four.

  • 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.

  • 2-5/16 inch Hitch Ball Recommendation Designed or Ball Mount with Hole Diameter of 1-1/2 inches

  • Tall Trailer Suspension Hanger with 9/16 Inch Diameter Hole
  • We do not carry a hanger with the same dimensions as # 115919 but with a 9/16 inch diameter hole. The closest match is going to be # E4139 which is 4-1/4 inches tall. The metal is approximately 3/16 inch thick.

  • 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 Weld-on Spare Tire Carrier Fit on an Aluma Salt Shield
  • Spare tire carrier # 413200 is normally installed on gooseneck trailers and welded into place. But you could use it on your Aluma Salt Shield provided that the surface it is mounted to can support the weight of the spare. Any welding should be performed by a qualified professional welder.

  • 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.

  • Replacement Axle for a 1991 Lowe Boat Trailer
  • None of the spindles we carry have the same measurements as what you have. The only real recommendation I could make would be to replace the axle since by the time you buy the spindles, have them professionally installed and get the correct hubs you're almost at the same price as just getting a new axle. In order to recommend an axle assembly for you, I'll need some more information. First, you will need to ensure that the existing wheels and tires you are using are rated for the extra...

  • Shorter 5-Leaf Double-Eye Spring # PR5 Than the Other 3 Purchased
  • You will be fine, I spoke with one of our installers here and he said that the springs will have small length variances due to one spring having more of a bow shape when compared to the other springs but once weight is put on the trailer after installation everything will even out as the springs all have the same spring rate.

  • Is Bonded 3-Wire # 18-3B-1 Available in Spools

  • Replacement Leaf Springs and U-Bolts for a 1987 Shore Line Boat Trailer
  • Thank you for submitting the photo of your setup. Considering the height of your axle and the amount of clearance you currently have from the axle to the frame of your trailer you wouldn't have enough room to put your axle above the leaf spring. You would barely have a couple of inches of suspension travel. For U-bolts you would want the part # SP01-160 and then for plates you would want the # 117594. Based on the dimensions of your current slipper springs the # WIG4 that you referenced...

  • Replacement Shackle Strap Recommendation that is 3-1/2 inches Long
  • Your question came in blank, but based on the picture you submitted it looks like you are in need a replacement shackle strap that is 3-1/2 inches in length. For that you would want the Shackle Strap # TRSL225. This strap is 3-1/2 inches long like what you have pictured with the hole measurements 2-1/4 inches on center. For a new shackle bolt you would want the Shackle Bolt part # 166081.

  • Triple Axle Spacing on 38-Foot Enclosed Trailer That Has Excessive Shackle Strap and Equalizer Wear
  • Thank you for providing a photo of one of your triple-axle trailer's shackle straps. For a newly manufactured trailer this apparently premature wear suggests your best bet be a return to the dealer where you purchased the trailer. If the trailer was refurbished or modified prior to you acquiring it then it is possible that the replacement parts installed may not have been correct. If you severely exceeded the trailer's rated weight capacity that could be one potential cause for the...
