Expert Answers about Redline

  • Is it Dangerous to Over Tighten Bolts on Equalizer and Shackle Bolts
  • Equalizer bolts, like the Redline Wet Equalizer Bolt with locknut and grease zerk, # 126B2, should be torqued to yield. Equalizer bolts are not given a specific torque rating because they should allow some movement of the equalizer. If they are torqued down too tight, the equalizer will have difficulty moving and that could bind up your trailer's suspension. Simply tighten the bolts down until they are tight, but still allow the equalizer to move. I have provided an installation video...

  • Is a Special Drill Required to Install the 2-1/2" Long Torx Trailer Screw # TFX250ACQ
  • The 2-1/2" Long Torx Trailer Floor and Wall Liner Screw # TFX250ACQ is designed for use on ACQ treated wood that is normally very corrosive to metal fasteners. Even if you don't have ACQ treated wood these screws should work great. Any drill should work fine, the correct bit to use would be the part # TX430-1.

  • What Size Hole is the T-Handle Locking Stainless Steel Flush Door Latch # L4080 Designed to Fit
  • The T-Handle Locking Stainless Steel Flush Door Latch # L4080 that you referenced is designed to be installed in a 2-3/4 inch by 3-3/4 inch hole. You will need to cut a hole that size in the door you have where ever you want the latch to be. For wood screws you could use the # TFX225ACQ for a 2-1/4 inch long screw or the part # TFX150 for a shorter screw that is 1-1/2 inches long. I attached a review video for this latch for you to check out as well.

  • Why Are There Both Round and Square Trailer Axles Used on RVs
  • Most of the OEM axles installed in RVs and most of the replacement axles we offer are indeed round in cross section. We do offer some square stub spindles for use on square axles, such as # SP204BT8, but these are usually limited to lower capacities like utility trailer applications. We do not have the ability to ship high-capacity axles due to their weight.

  • How to Install Redline Pre-Drilled Round Rubber Bumper # D2-96
  • The Redline Pre-Drilled Round Rubber Bumper # D2-96 can be installed in a variety of ways depending on the nature of the trailer. The holes are drilled all the way through to allow user-supplied hardware to mount it using the Steel Support Bar # SB2-96. We also offer a larger size bumper # D3-96 that measures 3-5/16-inches x 3-inches. No special tool is required for installation; you will use whatever tool is appropriate for the fasteners you choose.

  • Replacement Hub Assembly For Utility Trailer
  • We do have the parts you need for your trailer. I recommend the trailer hub assembly, part # 8-91-05UC1. This is a hub assembly that comes with bearings, races, seals, and the grease cap. The bearings included with the assembly will work fine. The seals in the assembly will not work for your spindles as the inner diameter is too large, but we do have a solution. These are 4 on 4 hubs and include the bolts on the hub and also include the lug nuts. You will need to order part # RG06-010...

  • How to Pick Out Replacement Hydraulic Brake Shoes
  • We have several sets of replacement hydraulic brake shoes available (see link to the right). Without knowing what size and brand of brake shoes you currently have though it would be impossible for me to recommend a set that would be confirmed to fit. What you will need to do is determine the size and brand of the brakes you currently have and then check out the link I attached and use the filters on the left side of the page to narrow down the results to see what would work for you....

  • How to Pick Out a Replacement Hub for a Trailer
  • In order to pick out the correct hub assembly for a trailer you are going to need know a few key pieces of information. The first thing you will need to know is the bolt pattern of your hubs. This is so you get a hub that is compatible with your wheels. I attached an FAQ article on determining bolt pattern for you to check out. Next thing you will need to know is what spindle you have on your trailer. In order to do that you can either get the inner and outer bearing numbers from a hub...

  • Finding Correct Location For Leaf Spring Hangers On Trailer
  • Since hangers need to be welded to the frame, it is important you have the correct location marked on the frame before welding them in place. This is not a really simple task if you are building the trailer from scratch. if you are just replacing your hangers and you are using the same axle and springs, then you would attach the springs to the axle, attach the hangers to the springs and locate the mounting position that way. If you are installing new axles and hangers and springs there...

  • Recommended Leaf Spring For 1,200 Lb Boat Trailer
  • The longest leaf springs we offer are the 4-Leaf Double-Eye Spring for 3,000-lb Trailer Axles, part # PR427. These springs measure 27 inches eye-to-eye and are designed for axles up to 3,000 lbs. I have attached a photo of this spring that has the dimensions noted you can check out. When measuring the springs, the weight has to be removed from the springs. The leaf springs I recommend for your trailer are the Redline 3-Leaf, Double-Eye Spring, part # 2-1020. This includes 4 round...

  • Leaf Spring and U-Bolts Recommendation for a Utility Trailer with 2 inch Square Axles
  • Sounds like you have 2 inch square axles on your trailer, for a set of U-bolt you would want part # SP01-160 and then for a U-bolt plate you would want the part # 117594. Now to pick out the correct springs you will want to first find out how much capacity your trailer and axles are rated for. This should be stamped on a plate near the coupler where the VIN is located. If it was a round axle I could give you a pretty good ball park of what the capacity would be, but square axles don't...

  • Recommended Size of Square Tube Axle for Square Spindle with 1.50 Diameter
  • The spindle you reference, # SP20848, has a diameter of 1.50. Your best option would be to use a 2" steel square tubing that is 1/4" thick. This will allow you to weld in the spindle square and snug. If you use a tubing that is less than 1/4" thick, you will have to make sure that spindle is welded in their square, concentric and snug. Square tubing will have a seam that is welded on the inside so you may run into an issue with the fit of the spindle in the tubing. Our strong suggestion...

  • Tandem Axle Spring Hanger Spacing Recommendation for # APT9
  • The hanger spacing needed for use with the # APT9 is 29-1/2 inches measured on center of the bolt holes. This works well with the equalizer since it's length (7-3/4 inches) is split on each side of the equalizer. When you add half of the equalizer to the length of your spring (25-1/4 + 3-7/8) you end up right at 29-1/4 inches which would work out perfectly.

  • What is Correct Hanger Spacing for Slipper Spring # WIC2
  • I conferred with two of my associates regarding your questions and the previous information you received. Based on this we suggest a hole-center-to-hole-center hanger spacing of 23-inches, rather than 23-1/8-inch. This is confirmed by Redneck, our resource for trailer suspension components. The hole-center of the front hanger should end up being about 11-1/2-inches from the axle center when under load, but you will not know this until you have installed the components. Just keep the...

  • Will 6-Leaf Double-Eye Spring # PR626 Work for 2000 MasterCraft Prostar 205 Single Axle Boat Trailer
  • In order to determine which springs are required, we will need to know the axle capacity of your 2000 MasterCraft Prostar 205 single axle trailer and the eye to eye distance of your springs when the trailer is unloaded. The axle capacity of a trailer can typically be found on a plate near the tongue, by contacting the manufacturer with your VIN, or by obtaining your bearing numbers and bolt pattern. If your axle does indeed have a weight capacity of 3,000 pounds and the eye to eye...

  • Need Drill Bit to Remove a Torx Fastener
  • It sounds like you are describing a Torx fastener, which has a star-like pattern. We do offer both Torx screws and screwdriver/drill bits in several sizes. Part # TX430-1 is a 1/4-inch TRX 30 size bit. Part # TX425 is a TRX 25 size bit. We also offer a TRX25 size L-shaped hand tool, part # 853-5171.

  • Distance Between Slipper Spring Hangers When Used with Slipper Spring # WIC2
  • The distance from the center of the bolt hole on front hanger to the rear hanger for the slipper spring # WIC2 would need to be 23-1/8 inches. I attached an FAQ article on slipper spring suspension systems for you to check out as well.

  • Changing Shackle Strap Length to Maximize Weight Capacity on Sagging Trailer
  • The first thing I would check on your trailer is the capacity of the springs. You need to be sure the spring capacity is rated at 1/2 the axle capacity. That way 2 springs equal the capacity of the trailer axle for proper fit. Check the arch of the springs with a level top of spring to top of spring to tie bolt. Next, check your tire size. At some time the tire size and wheel size may have been changed from the stock size. If the stock size is known you can return to that size and it...

  • How Much Sag Will Trailer Springs Have
  • After doing some research I found that springs will normally have about 1-1/2 inches of deflection when placed under the full capacity load, which means if you have a pair of the part # PR4B leaf springs installed, the weight would be 3,500 lbs. Another note is that you should allow for 'bump clearance' and tire clearance. The recommended distance for tire clearance is 3 inches. For the best overall suspension performance you should allow 2 to 2-1/2 inches clearance from the top of...

  • Ramp Door Lock Assembly Recommendation for an Enclosed Trailer
  • If you were to mount the 36" Lock Side-Door Bar Lock Assembly # 305736 on the edge of the corner of your trailer the handle could swing around the corner beyond 180 degrees as there is not a stop in the hinges of the lock. So yes, this could swing 270 degrees from the mounting plane so it should work well for you.

  • High Capacity Spindle for Hay Wagon
  • I wish we did, but we do not carry any 10k rated trailer spindles. The highest we have is a 6k spindle like part # AS3000F. This is an agricultural spindle that could work well on your hay wagon as long as you didn't need more than a 6k capacity. Otherwise we do carry 10k rated hubs, (see link to the right), if you can find the spindles elsewhere.

  • How Does the Dust Cap Driver Tool # 290-991 Remove a Dust Cap
  • To use a Dust Cap Driver Tool # 290-991 for removal you will need to put it over the dust cap and then use the leverage the handle creates to pry on the cap to get it to wiggle it loose like you said. When you get it to start coming loose it should be easily removed as the cap is tapered.

  • Function Of Trailer Vents On Enclosed Trailer
  • The vents we offer for an enclosed trailer like part # 9139 are designed to allow air into the trailer. None of the vents we offer create a pressurized condition in the trailer and none are equipped with an air filtration system to keep dust out. Some of the features on the vents like # 9139 allow you to adjust the amount of airflow in the trailer with a butterfly valve mounted on the inside of the vent which would be operated from inside the trailer. Other trailer vents, like part...

  • We do offer trailer fenders for several size wheels, but the largest diameter wheel we have a fender for is a 16.5 inch. The fender we offer for the 16.5 inch wheel is part # F13X36-1R. This fender is constructed of 16 gauge steel and is a weld-on application. it measures 13 inches wide, 36 inches long and 20 inches tall. This fender also features a 1 inch radius lip on the front and a 90-degree angled back for mounting. The prices for any of our items are listed on the right side of...

  • Thread In Gooseneck Hitch Ball Recommendation
  • The gooseneck hitch ball part # 2516-2CT is very close to being exactly what you need. It has a 2-5/16 inch ball that has a 2 inch shank diameter that is also 3-1/2 inches in length. The threads are coarse though. The only other option we have that would be fine threaded would be the # 32M except it has a 3 inch diameter ball and is 1/4 of inch shorter than what you need.

  • Can Just One Cable be Used on Enclosed Trailer Ramp Spring ERS80S66
  • The manufacturer of trailer ramp spring # ERS80S66 makes it very clear that the unit has to be installed according to the instructions and a professional installation is recommended. This is because torsion springs like this can be dangerous to work with. Using just one of the drums instead of both is not recommended. You would want to go ahead and use 2 cables for proper operation.

  • Hub, Mounting Flange and Brake Assembly Recommendation for the EZ Lube Spindle part # R104BTREZ
  • All of the parts you listed are compatible with each other and would be the correct ones for you to use.

  • Tips for Trimming 2-Piece Polypropylene Trailer Vent to Fit a Thin Wall
  • The easiest way to trim the round vent piece in Polypropylene Trailer Vent # HMAV2-AVT2 is to first determine how much needs to be trimmed but placing it through the hole in the trailer wall. Mark the proper depth on the vent piece then remove it from the wall. For a straight, clean cut I recommend a rotary tool. You could use a hack saw with fine teeth as well but I would be careful to keep it as straight as possible. You will likely have to sand off some rough edges no matter how it is cut.
