  • Can the 6-Foot Long Stainless Steel Piano Hinges be Cut In Half
  • All of the hinges we sell like # SH150 are 6 feet long. You can certainly trim a 6-foot length as needed provided you use the proper saw with a blade designed to cut metal. Hinge # SH150 is stainless steel, 6 feet long, and 1-1/2 inches wide. Hinge # SH200 is stainless steel, 6 feet long, and 2 inches wide. Hinge # SH300 is stainless steel, 6 feet long, and 3 inches wide.

  • Will the Spare Tire Carrier Part # 413200 Mount On The Side of a Carson 5 x 10 Utility Trailer
  • Yes, If you have an enclosed utility trailer, you could bolt on the spare tire carrier, # 413200, to the side provided that you were to re-enforce the area where the carrier is to be mounted. You can do this by attaching wood cross braces inside the trailer between vertical frame posts. Then, when you bolt the carrier to the outside, you would bolt it through the side of the trailer and into the wood cross braces. You will have to drill holes in the carrier in order to bolt it into place. If...

  • Parts Need to Build Off Road Trailer
  • Square axles can be tough to determine capacity, however the set up you reference above should be more than adequate for a towing weight of 1750 pounds. The Redline Spindle for Square Axles # SP20484, which you referenced, is a square spindle designed for 2 inch square axles and has a weight capacity of 1750 lbs, so it will work great for you. This spindle, # SP20484, is indeed compatible with Trailer Hub Assembly # 84655UC1, which you referenced. The hub assembly comes with the bearings,...

  • 5-on-4-1/2-Bolt Pattern Hub for Use on Redline 2-1/4-Inch Spindle # R56042
  • Selection of a compatible hub for use on the Redline Spindles # R50642 requires matching up the bearing set that fits this spindle (25580 inner bearing and LM67048 outer bearing) to the bearings in the hub. We do offer a number of hub kits that use this same bearing set and all can be seen on the link at right. However, none of these has a 3500-lb capacity and none has the required 5-on-4-1/2-inch bolt pattern. All of these hubs use at least 6 lugs. You may find it easier to select...

  • Can a Spring Latch Pin be Used to Hold Trailer Ramps On a Trailer
  • The 7/16 inch diameter of the pin in the latch pin # SL716SS is on the small side for heavy car trailer ramps. It does not have an official capacity but if it were me I would do with something with a larger diameter. Spring latch # SL58W has a 5/8 inch pin. It and the 7/16 inch latch pin do not have weight ratings but they are meant for trailer doors which are not all that heavy. I recommend just using a hitch pin with clip, # PC3. Hitch pins are meant for more weight and you would...

  • Determining Axle Length for Home-made 4 x 8 Trailer Using Square Stub Spindles
  • You can use the 8-3/4-inch overall length of the Redline 1-1/2-inch Spindle # SP204BT8 to help you determine the correct length for your axle tube. You also need to take into account the width of the tires you intend to use as these also will increase the width of the overall combination of the axle, spindle, hub and wheel. Start with the overall width of the trailer and its fenders/wheel wells, subtract the widths of your two chosen wheels and the lengths of the two spindles to determine...

  • Availability of a Slipper Spring that is 2 inches Wide
  • It's a spring designed for a 9,000 lb axle, but we do have a slipper spring that fits the dimensions you are looking for. The part # 72-10-2 is 2 inches wide and is 30 inches in length. I also attached a link to a page that has all of the slipper springs we carry that are 2 inches wide. You would not be able to use a 1-3/4 inch wide spring on your current setup without also replacing the hangers.

  • Can Leaf Spring Shackle Straps Be Installed Between Leaf Spring and Front Spring Hanger
  • On a single axle trailer, the shackle straps must be to the rear of the axle, attaching the leaf spring to the spring hanger. This allows the axle to deflect upwards and to the rear if you hit a bump. If the shackle was at the front, the axle wouldn't be able to deflect in the correct direction, which would result in suspension components, likely the spring hangers to be damaged.

  • Spring Hanger Spacing for the Hanger Kit # APS1 with PR4B Springs
  • The recommended distance between the hangers of the # APS1 would be 25-3/4 inches when using the leaf spring # PR4B. When the trailer is set on the ground and the leaf spring is supporting the weight of the trailer the spring will flatten out and get longer so that the shackle will face the correct way.

  • How to Order the # PR5 Leaf Spring with a 1/2 inch Diameter Bushing
  • The 5-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # PR5 that you referenced is only available with a 9/16 inch bushing. What you could do is remove the bushing of the # PR5 and replace it with a # TRBU11506.

  • 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...

  • Cam Door Latch Recommendation for a Trailer Side Door
  • The width of the door on your trailer won't really matter when considering either the 36 inch tall version part # 305736 or the 55 inch tall # 3057-55 cam door latch. I would measure the height of your door and go with the biggest one that will fit the height of your door.

  • Will the Spare Tire Carrier # 413200 fit a Wheel with a 5-1/2 inch Bolt Pattern
  • Yes, the Spare Tire Carrier # 413200 that you referenced has been confirmed to fit 5 and 6 lug wheel bolt patterns so it should do just fine on yours that has either a 5 on 5-1/2 inch or 6 on 5-1/2 inch bolt pattern. I attached an FAQ on determining bolt patterns for you to check out as well.

  • Availability of 9/16 U-bolt With 2-1/2 Inch Inside Dimension By 7-1/2 Inches Long
  • I don't have an exact match, but part # 175668 should work just fine for you. The U-bolt is designed for 2-1/2 inch axles, and has an inside dimension of 2-5/8 inches. The bolt is 9/16 in diameter and is 7-3/4 inches long.

  • 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...

  • Installation Instructions for Redline Left Hand Ramp Spring # RS16933LH
  • In addition to watching our video review I attached, to use this spring on your trailer you must have ramp hinge with a 1-1/2 inch diameter rod or pipe where the ramp meets the trailer. The spring slips over the rod with the tension of the spring against the ramp and trailer when the ramp is in the up position. The spring should not be welded to the ramp or trailer, the tension and the rod will hold the spring in place. Note that the Redline Ramp Spring # RS16933LH is a replacement spring...

  • Lug Nut Wrench Recommendation for Lug Nuts that fit 9/16 Studs
  • Your lug nuts that you have on your 8,000 lb axles are designed to fit a 9/16 stud. That is not the size of socket you would need. Since lugs of the same thread size can have various socket requirements it would be hard for me to say specifically what size socket or wrench you would need. I can recommend the # LW433 or the # LW405 since they come with various sizes that can be used on nearly all available size lugs.

  • Dimensions of the Center Hanger part # 29-43-2
  • I spoke to my contact at Redline and he informed me that the dimensions of the Center Hanger part # 23-43-2 are 5-1/2 inches in overall height, the outer width of the hanger from where the bolt runs through the hanger is 4-1/4 inches and the inside width would be 3-3/4 inches. Then length of the hanger would be 5 inches.

  • How to Determine Axle Positioning on a 40 ft Long Dove Tail Trailer
  • To determine the location for the front and rear hangers on your tandem axle trailer you will first need to make sure that you have the correct center point for your equalizer hanger. The center point of your equalizer hanger needs to be located where you will have 60 percent of the frame of the trailer in front of the center of the equalizer hanger and 40 percent behind the center of the equalizer hanger. For example, if the trailers frames length is 40 feet like yours, then the center-line...

  • I went out to the warehouse and pulled a 4-Leaf Double-Eye Spring, # PR4B, to measure. At the center of the spring where the bolt is, the total width, including the bolt, is 2 inches. The width of just the leaves is 1.30 inches. Each leaf is approximately 0.30 inches thick.

  • Looking for Wheel Cylinders to Fit 1976 Calkins Boat Trailer with Dico Brake Assemblies
  • Although I was unable to cross-reference the Wagner PE-1420 part number that you provided, we do offer replacement wheel cylinders for Dico brake assemblies. If you have 10 inch or 12 inch Dico brake assemblies with a single serve wheel cylinder, you will need Replacement Wheel Cylinder, # BP17-030 for left hand side and # BP17-020 for right hand side. If by chance you have a different brake assembly or style of wheel cylinder, please feel free to send me a picture and I would be...

  • Can a Trailer Suspension Hanger Be Drilled Out so that a Larger Bolt Could Be Used

  • How to Pick Out Replacement Leaf Springs for a Trailer with 2 inch Wide Double Eye Springs
  • All of the double eye leaf springs we carry are 1-3/4 inches wide. The best recommendation I could make would be to find out what the axle capacity is for your trailer and then go with the springs that are rated the best based on that. You are going to have to install new hangers anyway so you really wouldn't need to match up the lengths of your old springs. Near the coupler of the trailer there should be a plate or sticker with the axle capacity of your trailer listed. Once you have...

The weight capacity for this wheel is 1,870 lbs. We also have a 7.00-15 tire that will work with this wheel. It is the Kenda Tire K391M, part # AM10414. This tire is a Load Range E tire and has a 10 ply rating. This tire has a maximum load rating of 2,403 lbs at 70 psi. We do not offer a Load Range D tire that is the size you asked about.

  • 30 inch 1,500 lb Leaf Spring Recommendation
  • The best recommendation I could make for you would be a 1,500 lb spring like the part # PR427 and have the hangers moved so that they accommodate this 27 inch spring by a qualified welder. I attached a review video and an FAQ on trailer suspension for you to check out as well.

  • Where to Measure on Trailer Spindles to Determine Replacement Hubs
  • You will need to measure the diameter of the spindles where the seal and bearings ride. Check out the picture I attached that shows where this is. You will need an exact measurement so either a digital or dial caliper will be needed. To pick out the correct hubs you will also need to determine the bolt pattern of the hubs you currently have so that the new ones will be compatible with your current hubs. I attached an FAQ on how to determine this. If you get back to me with that information...
