Expert Answers about Redline

  • 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...

  • 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...

  • What Is Torque Rating For Lock Nuts When Installing Leaf Springs On Trailer
  • When you are installing leaf springs like part # PR4 on a trailer, you would need to torque the lock nuts based on the diameter of the U-bolts you are using on the installation. A 1/2 inch diameter bolts should be torqued between 45 ft/lbs and 70 ft/lbs. A 9/16 inch diameter bolt should be torqued between 65 ft/lbs and 95 ft/lbs and a 5/8 inch diameter bolt should be torqued between 100 ft/lbs and 120 ft/lbs. The shackle bolts do not have torque ratings because over tightening will...

  • Does Wet Bolt Have Screw-In Or Press-In Zerk Fitting
  • The Step wet Bolt For 1-3/4 inch Double Eye Springs, part # 34007-187-00 you referenced does have a screw-in Zerk fitting. If you look at the base of the fitting on the bolts you can see where a wrench can be used to install the fitting. If you look at a different wet bolt like part # 126B2 you will see it does not have the hex feature on the fitting. This would be a press-in application for the Zerk.

  • Redline # PR5 Double-Eye Trailer Leaf Spring Capacity and Installation
  • The Redline # PR5 Double-Eye Trailer Leaf Spring you referenced has a 3000-lb rating and when used in a pair they are suitable for use with a 6000-lb-rated axle. Leaf springs should ALWAYS be replaced in pairs in order to ensure proper axle alignment and suspension performance. This 5-leaf spring measures 25-1/4-inches from eye-center to eye-center. If your trailer is a single-axle type then the spring eyes will bolt to your front and rear hangers. If your trailer is a tandem-axle type...

  • 13 Inch Wide Trailer Fender Recommendation
  • The only 13 inch wide trailer fender we offer is the Redline Trailer Fenders # F13X36-1R. The flat inside edge of the fender could be used to bolt the fender on. You would need to drill holes in that edge to run nuts and bolts through the fender and the trailer.

  • 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....

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.

  • 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

  • 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...
