  • What is the Torque Requirement for 1/2 Inch U-Bolts for Trailer Suspension
  • According to our FAQ on slipper springs, linked for referenced, the torque specs are as follows: Torque Ratings 1/2 inch Bolts: 45 ft/lbs - 70 ft/lbs 9/16 inch Bolts: 65 ft/lbs - 95 ft/lbs 5/8 inch Bolts: 100 ft/lbs - 120 ft/lbs The Replacement U-Bolt, # 1753223, uses a 1/2 inch nut so it would fall into the 45 to 70 foot pound category.

  • Recommendations for Reducing Sway with a 53 Foot 4 Car Wedge Trailer
  • It is possible, but not likely, that a fifth-wheel setup will help reduce the sway that you are experiencing when towing your 53 ft. 4 car wedge. The gooseneck setup that you are using should be appropriate for towing the trailer and normally gooseneck setups are rated for higher towing and tongue weights than fifth-wheel setups. In my experience, on the farm with hay, livestock and a tractor once in a while, the best defense against sway is proper trailer loading. You will need to position...

  • What is the Torque Rating for a 1/2 Inch Lug Nut on a Dually Trailer Wheel
  • For a 1/2 inch lug nut, you will want to torque each nut down to 75 to 85 foot pounds. It does matter if it is a single wheel or dually wheel. You will want to avoid using an impact wrench or any other tool that cannot provide measured force. Use a torque wrench for accurate results.

  • Can I Use Passenger Vehicle Tires On My Tandem Axle Boat Trailer
  • I would not recommend using passenger vehicle tires on your tandem axle boat trailer. You will only want to use trailer tires that have the letters ST in the size. ST stands for Special Trailer tire, which is meant to be used on boat and utility trailers. Trailer tires have a thicker side wall and are designed for carrying trailer loads. You should always keep trailer tires inflated to the maximum PSI rating. I have linked an FAQ Article on trailer tires that you may find as a good reference.

  • What Are The Dimensions and Bolt Hole Spacing For U-Bolt Plate Part # 12-53
  • I measured U-Bolt Plate, part # 12-53, and the bolt hole spacing is 5 inches inside hole to inside hole and 3 inches inside hole to inside hole. The overall dimensions of part #12-53 are 6 inches by 9 inches and 1/4 inch thick. I contacted our representative at Redline and he informed me that part # 12-53 can be used with 10K heavy duty, 5 inch round axles with 3 inch wide springs. I have linked a picture that I took of part # 12-53 that shows the dimensions and bolt hole spacing.

  • Trailer Wheels for a 1984 Holsclaw Trailer
  • Without knowing the bolt pattern and tire and wheel size, you will need to take some measurements of the tires that are currently on the trailer. Measure the tire's diameter and width. Also, you will need to determine the proper bolt pattern on the trailer wheel. Please note, there may be a slight size variance due to the age of wheels and tires currently on the trailer. Most of our website pages for trailer wheels and tires will show you how to measure a bolt pattern at the bottom of the page.

  • What is the Maximum Amperage Draw of Trailer Brake Magnets on a Tandem Trailer with Four Brake Drums
  • Maximum amperage draw for 4 Brakes that are 10 or 12 inch diameter is 15.0 to 16.3 amps at 12 to 13 volts. The 14 gauge wire may be sufficient but for maximum braking effectiveness at full load capacity. I would opt to run 10 gauge wire. Larger wire will only help the effectiveness of the trailer brake system and 10 gauge is what we use when installing trailer brakes even on single brake axles with 7 inch brake assemblies. We offer Jacketed 2 Wire, 10 Gauge, Brake Wire, item # 10-2-1,...

  • Replacement Leaf Springs for 1989 TeeNee Boat Trailer
  • As leaf springs become worn, they tend to flatten out, which would explain the slightly longer dimensions of your existing slipper spring. The correct replacement spring you need will depend on the capacity of your axle. If your TeeNee boat trailer uses a 3500 lb axle, then the # WIG4 is the correct replacement. For a 3000 lb axle, use # WIF4. Leaf springs should be replaced in pairs.

  • Is the 20.5 X 8-10 Trailer Tire and Wheel, part # 2058TW5-E, Balanced
  • The Tire and Wheel Combo, part # 480TW4-B , is received from the supplier already with the tire mounted on the wheel. The supplier does not balance the combination, but when the tire is installed to the wheel they will line the high (heavy) spot on the tire with the low (light) spot on the wheel. This does not completely balance the tire and wheel combination but it does eliminate any excessive out of balance condition. It would be a good idea to have them balanced before you install...

  • Can I Use a Higher Capacity Tire or Wheel and Tire Combination on a 24 Ft Wells Cargo Trailer
  • First, we need to determine the axle capacities and gross trailer weight (GTW) capacity of your 24 foot Wells Fargo trailer. The reason axle and GTW capacity is important is if you upgrade the tires or tires and wheels to handle more capacity, you will be putting more stress on the trailer suspension, axles and bearings, making one or more of these parts the weakest link in the system. It is much easier on the trailer, you will get a better ride and it is safer, if the tires are properly...

  • How Can I Pull a Gooseneck Trailer with My 5th Wheel Hitch in My 2005 Ford F-150
  • Yes, we have both a product that will accomplish what you are looking to do and a video that features the product being installed into a truck. You could use a Gooseneck to Fifth Wheel Trailer Adapter - Square, part # KP84HB, like you referenced. This would allow you to tow your gooseneck trailer with your fifth wheel hitch. Another option is to get a Pro Series 25K Gooseneck Plate for Fifth Wheel Rails by Draw-Tite, part # 49080. This product will install onto the rails of your fifth...

  • Will 2-1/2 Inch U-Bolts Fit a 6,000-Lb Hammerblow Axle On a Homebuilt Trailer
  • The U-bolts on a trailer suspension are designed to attach the leaf springs to the axle of the trailer. The U-bolts will need to fit the diameter of your axle. I would recommend to measure the diameter of the axle. A 6,000-lb axle should have a diameter of 3 inches. The spindle that is attached to the axle will measure 2-1/4 inches in diameter. There is not a U-bolt available in a width of 2-1/4 inches. The Redline Replacement U-Bolt, part # 176500, is a U-bolt that is designed for...

  • Trailer Spring Selection for a 1974 Two Horse WW Horse Trailer
  • To determine the proper leaf springs to purchase we will need to get some measurements and a few other details. First we will need to know if your trailer has double eye springs or slipper springs, next we need to know how many axles the trailer has and the weight capacity of your trailers axle or axles. Measurements needed are the distance from the center of one eye to the center of the other eye on the double eye leaf spring and from the center of the eye to the highest point on the slipper...

  • What Is the Torque Rating for Lug Nuts on a Mobile Home
  • Typical torque rating for car, truck and SUV lugs is 90 ft. lbs. As always, you should check with the manufacturer of the mobile home for proper ratings. Vehicle weight, lug type, hub type, etc. all play a role in the torque rating and the best way to find out would be to call the manufacturer of the mobile home.

  • Parts Needed to Increase the Capacity of a Boat Trailer
  • The only way to increase the capacity of a trailer is to get a higher capacity axle (and related suspension components, hubs, tires, and wheels). I would go with a 3500 pound axle since that is what the springs, when combined, are rated for and because it will cover the weight of the boat with ease. You may need to also beef up the trailer frame as well. The trailer manufacturer may be able to tell you if the frame is rated high enough as-is. For wheels and tires, I recommend an ST205/75-14...

  • Spindle Recommendation for a Broken Zerk Fitting on a Spindle
  • I spoke with my contact at Redline and he informed me that there is a replacement zerk fitting for your spindle but that it is not the same as one you would see on a tractor or anywhere else. It would be a special order item that we would need to order from our distributor. Or you could replace the spindle. If this EZ Lube Spindle 1.75 inch RD x 3 inch, part # R20384EZ, has the same dimensions as the spindle that is on your trailer now this would be a good replacement. You will...

  • How to Remove a Hub from a Ram Line Jet Boat Trailer with Damaged Bearings.
  • Unfortunately, it sounds as if when your bearings went out you were towing the trailer and the inside of the bearing that contacts the spindle, bearing cup, got hot and galled itself to the spindle on the trailer. This happens many times when bearings fail and can require replacement of the whole axle in the most extreme cases. I would try to remove the bearing cup by prying with a pry bar or screw driver and lubricating the spindle. If that doesn't work try more aggressive techniques....

  • How To Determine Replacement Leaf or Slipper Spring for 1996 Nitro Bass Boat Tandem Axle Trailer
  • You will need to measure the distance from the center of each mounting point on the end of the leaf springs. If you look on the page for part # PR3, the measurement you will need is measurement A as shown in the diagram. If you have slipper springs, you will need to take 4 measurements. 1. The distance from the center of the mounting hole to the end of the slipper spring 2. The distance from the center of the mounting hole to the highest point of the slipper spring. 3. The height...

  • boat trailer hub/spindle assembly
  • Spindles get welded to axles so there really is not an easy way to replace one on the side of a highway. The best advice I could give to you would be to periodically check the condition of the bearings on your trailer and be sure to grease them regularly and you should have a pretty reliable trailer setup. Check out the video I attached on bearing inspection for you.

  • 205-75/15 Tire and Wheel Combination Needed for 5 on 3-1/2 inch Bolt Pattern Travel Trailer Hubs
  • At this time we do not carry a trailer wheel with a 5 on 3-1/2 inch bolt pattern. The smallest 5 bolt pattern we carry is the 5 on 4-1/2 inch bolt pattern that you mentioned. The only smaller bolt pattern that we carry is the 4 on 4 inch bolt pattern, see link. Tires for the 4 on 4 inch bolt pattern typically only go up to 13 inch wheel diameters. You may be measuring your wheel bolt pattern incorrectly. Just in case this is the issue, I added a link to our trailer wheel bolt pattern...

  • Replacement Key for a T-Handle Locking Stainless Steel Flush Door Latch
  • It is possible that replacement key # KEYCH506 will fit. However, since your lock number starts with an EM I cannot guarantee that it will work. The other option is to replace the lock using # UWSLOCKCH506. To replace the lock you will need access to the back of the handle. There should be a nut that secures the lock to the body of the handle assembly. Loosen and remove it and the lock will come out the front. Reverse the process to install the new lock.

  • What Does AWG Stand For on the Redline Quick Splice 14 - 18 AWG Wire Connector # 564
  • The acronym AWG on the Redline Quick Splice Wire Connector, part # 564, stands for American Wire Gauge. This is the standardized wire gauge system used in the United States and Canada. On the # 564 connector it means the connector fits 14 to 18 gauge wire.

  • Can V-Keel Rollers be used on a Wood Sea Wall to Move a Pontoon Boat
  • This could work but make sure the wall can handle it. The roller, # 811, does not have an official capacity but just for the ease of moving the boat on them I would use as many rollers as could fit. The issue is that since the entire boat is not supported at the same time, it could end up damaging the boat. Another option is to construct a device like in the picture I have included using rollers, # DL21741, and some lumber. With this type of set up, it would be very easy to move the...

  • Replacement Bearings and Seals Needed for a 1989 Escort Single Axle Boat Trailer
  • I did some research and found some information that you may find helpful, but to determine the correct parts for replacing the bearings and seals on your Escort boat trailer axle, you will need to remove one of the hubs and get the part numbers off of the inner and outer bearings and seal. The bearing part numbers are usually etched into the back of the bearings and the seal part number is usually embossed in the rubber portion of the seal. Escort does not list axle capacity or bearings...

  • Torque Rating For Shackle Bolts and Which Way Should a Lock Nut Go On a Bolt
  • For the 9/16 inch diameter bolts a torque rating of 65 to 95 foot pounds is right where you want to be. Lock nuts will only thread on properly one way so it is fairly easy to determine if you have it on correctly when you start to turn it by hand. On a nut like # TRFA916DLNZ there are markings on it as you can see in the picture. Other lock nuts are wider on the end that goes onto the bolt so it is clear on those as well.

  • Availability of 1 Inch Diameter Trailer Spindle To Fit on 1.25 Square Axle
  • The two spindles that I have to fit a square axle are designed with a square stub diameter of 1.50 inches. The Redline Spindle, part # SP204BT8, you have referenced is for 2,000-lb axles and the Redline Spindle, part # SP20484, is for 3,500-lb axles. They use different bearings and seals. I am including a link to a product page that will list the dimensions on the trailer spindles we have available. Square axles can be tough to determine capacity. Often times the same spindle fits...

  • Adding Lift To 2003 Jayco Single Axle Tent Trailer
  • I spoke with my contact at Jayco about your 2003 single axle trailer. There is no lift kit available but we may have an option for you. If your 1-3/4 inch axle is round and you have underslung leaf springs, I recommend installing a new spring seat on top of the axle, like the Spring Seat for Typical 2000-lb, Round Trailer Axles, part # TRSS175. Simply flipping the axle is not an option because axles are made with a slight arc so that they can handle the load on the trailer. When placed...

  • Removal and Installation of a Unitized Oil Seal for a Trailer Oil Bath Hub
  • Unitized oil seals such as # 10-63 for example are different than regular grease seals. Unitized seals have an inner part that stays fixed to the spindle on the axle and its outer case rotates with the trailer hub. You would remove and reinstall a new one the same way you would with a regular seal. The best tool to use for unitized seals is a seal removal tool which you should be able to get at a local auto parts store. Once you pry out the old seal, place the new one in the hub. Use...

  • Fender Recommendation for a Bantam Trailer
  • I am not very familiar with the tire size 16-6.00, however, I am familiar with the older agricultural tire size 600 x 16. Typically, you will want to choose a fender based on the size of your wheel. If you have 16 inch wheels, then we have 2 fenders that will fit that size. The Redline Single-Axle Fenders, part # F13X36-1R, and part # F1075X36-1R. The main difference between these two fenders is the width. Part # F13X36-1R has a width of 13 inches and part # F1075X36-1R has a width...

  • What is the Usable Length of the Heavy Duty Linchpin, # LP716HD
  • The usable length of the Heavy Duty Linchpin, # LP716HD, is from the end of the pin up to the head that holds the ring (because the head will not fit through the 7/16 inch diameter hole, it is not part of the usable length). The usable length is 1-3/4 inches (1.75) so it will fit your application. I have made a picture that shows the usable length for you.
