Video Transcript for Review of etrailer Trailer Leaf Spring Suspension - Spring Mounting Hardware - TRSL313

Today we'll be taking a look at the shackle strap. This is going to be the connection point between your double-eye leaf spring to the rear hangar on your trailer or to the equalizer on your suspension system. This is going to provide that pivot point for those components to work properly, and help to distribute the weight across your axles. That's going to help your trailer to move better, and distribute the weight over your suspension system.This strap is made of a steel construction. We'll go over some measurements. The distance from the center of one hole to the center of the other is about three and a quarter inches, or three and an eighth inches.

You can see there. The distance overall from end to end is about four and a half inches. The width is about one and a quarter, and the thickness is just under a quarter of an inch, about seven 32nds.It does come with a single shackle strap. The diameter of either of our holes is nine 16ths. And that's going to do it for a look at the shackle strap..

I fabricate roll-out boat docks. I also fabricate light weight hinged shore ramps to make the transition from dock to shore. We weld 2 shackles at the end of a dock and the end of a ramp. We secure the ramp shackle to the dock shackle with a straight clevis pin and cotter creating a simple hinge effect. I like buying them in bulk vs a retailer that sells them in 2 paks and etrailer provides a good product at a fair price. 488048

Using etrailer.com has been a great experience. They have a huge selection of trailer parts and make it very easy to find the right parts. The packaging seems to have gotten alot better. Very sturdy box. It arrived within a few days from ordering which was a huge plus. I was able to get the job done sooner than planned. That kind of experience will keep me loyal to etrailer for any future trailer parts needs. Thanks guys and gals. Keep up the great work. As far as the parts, eveything was heavier duty than factory. Since I measured the old parts I was able to find the exact replacements for those parts. The job went so smoothly without any issues. These springs raised the trailer height without any load on the axles 1.5 inches. It was definitely time for new springs and hardware. Im kind of glad the one spring broke. 469714

Loved the personal service and the help. I tried a few other sources before going online to order from etrailer. One place I tried was an online tool dealer, and their online site was a mess without help and so was a retail location. etrailer, was quick to find me exactly what I needed and got me fixed up in just a few minutes. From now on all my trailer needs will be fulfilled from etrailer!!! 466191

Ask the Experts about this etrailer Trailer Leaf Spring Suspension
Do you have a question about this Trailer Leaf Spring Suspension?


  • Can Equa-Flex Cushioned Equalizers Replace Longer Triangular Equalizers
  • You can use the Equa-Flex Cushioned Equalizers # LC279687 as a replacement for your current equalizers, which are equivalent to the Triangular Equalizer # TREQ310 but you will need to replace your shackle straps as well. The reason for this is the Equa-Flex measures 5-1/2 inches wide while your current equalizer is 6-1/16 inches wide so longer shackle straps such as the Shackle Strap - 3-1/8" Long # TRSL313 would be needed, assuming your current shackle straps are the standard 2-5/8...

  • Replacement Bushings, Eye Bolts, and Shackle Straps for a 1-3/4 Inch Wide Leaf Spring
  • The prices are a reflection of factors such as demand, availability, cost, and several other variables. The nylon bushings are also the least cost effective component of the kit. Unfortunately, we do not offer the Never Fail Tandem Axle Suspension Upgrade Hardware Kit for Double Eye Springs part # LC281285 with 1-3/4" long bushings. If you have 1-3/4" wide leaf springs then you will want to piece your own kit together with the Never Fail Bushings part # LC279685, Shackle Bolt with Locknut...

  • Limited Tire Clearance with Stock Tire Size on a 2006 Forest River Cherokee 27Q
  • We recommend having a minimum of 3" between the top of the tire and bottom of the fender in order to allow for proper suspension travel. However, based on the photo you sent I believe you need new leaf springs as the ones you have appear to be almost completely flat. This has then compromised your tire clearance. The flattened leaf springs could either be a result of overloading the trailer or just general wear. In order to replace them you would need to know your axle capacity and...

  • Differences in the Redline Single-Axle Trailer Hanger Kits, # APS1, #APS2, and # APS3
  • The APS1, APS2, and APS3 are all suspension kits for single-axle trailers with 1-3/4-inch double-eye springs. They are designed for use on trailers with single, 2,000-lb to 7,000-lb axles. The difference in the kits are in the rear hangers and the shackle straps. The Redline Single-Axle Trailer Hanger Kit, part # APS1, uses the Redline Rear Hanger, part # 30-20, which uses a steel bushing and is .91 inches tall. The shackle straps are the Shackle Strap, part # TRSL313, which are...

  • Should Shackle Straps Angle Towards the Axles or Away From Them
  • In order for your trailer suspension to function properly you will want the angle of the shackle strap to be towards the axle so that as the leaf spring compresses and expands it will have somewhere it can go. Otherwise, you will not get the optimum performance from your trailer suspension. It may not be super dangerous, but if the suspension is not operating properly you could cause premature failure which might endanger yourself and other motorists. Check out the picture I attached that...

  • Replacement Shackle Strap Recommendation For Single Trailer Axle Suspension
  • The shorter shackle straps that measure 2-5/8 inches long like part # 115052GALV are typically used on dual or triple axle systems. A shackle strap that measures 2-1/4 inches long like part # TRSL225 are usually found in a dual-axle kit. I have attached a photo of a shackle strap that shows where you should measure to make sure you get the correct length. Unless you are changing the springs, or other parts of your trailer suspension I would recommend using the same length strap when...

  • Recommendation For Leaf Springs and Shackle Straps on a 2001 King Boat Trailer
  • When replacing the leaf springs on your boat trailer you will need to match all of the dimensions and the spring capacity as closely as possible to the original spring. Usually the measurement from eye to eye will lengthen and the height measurement will decrease with wear. See picture I have included that will show the measurements you will need to match to replace your leaf springs. The number of leaves in a spring pack does not have to remain the same as long as the weight capacity...

  • Recommend Hangers, Shackle Straps, and Bolts for Equa-Flex Cushioned Equalizers # LC279688
  • For a center hanger you will want something that isn't too tall because equalizers # LC279688 are quite tall compared to regular equalizers. Hanger # 115918 is what I would go with. The front and rear hangers would need to be taller than the center so I recommend # E4139. Then for shackle straps I recommend # TRSL313. This should get you right about level. So you will need: 2 of hanger # 115918 4 of hanger # E4139 8 of shackle strap # TRSL313 14 of wet bolt and nut # 126B2 The...

  • Modifying Trailer Suspension to Gain Ground Clearance
  • Doubling the capacity of your springs honestly won't gain you any more capacity. You'd still be limited by the capacity of whatever the lowest-rated component would be, whether it's the tires, hubs, spindles or axle. The higher capacity springs would make for a very stiff ride, and that's about it. Going with longer shackle straps won't gain you more ground clearance. If your springs are mounted to the underside of your axle, you can use a over under kit, and move them to the top of...

  • Recommended Shackle Straps or Hanger Kit for Single Axle Trailer

You are correct that that bolting to your hangers on both ends is not correct, however the size of the shackle strap needed is determined based on your hanger length as you can see in these kits. So, the Shackle Strap - 3-1/8" Long # TRSL313 may or may not be a good fit based...

  • We do not have any kits that have all the components with the dimensions you asked for. You can go a couple ways. You can choose to go with the kit you asked about, part # APT4, and then choose different shackle straps. You will need a quantity of 8 shackle straps. We do not have 3 inch shackle straps available. We do have part # TRSL313, that measures 3-1/8 inches center to center. The overall length is 4-3/8 inches. Or you can order the following components separately (2) 6-1/4...

Both of these shackle straps have a bolt hole to bolt hole measurement of 3-1/8" with 9/16" diameter bolt holes. The above u-bolt has a 7/16" diameter bolt therefore the above shackles straps will work for you but the bolt holes will be slightly larger, 1/8" to be exact.

  • Can Tandem Axle Spring Hanger Spacing Be Increased to 30-1/4-Inches to Fit Larger 235/80R16 Tires
  • For your 3-inch axles the normal spacing of the hangers included in the DexterTandem-Axle Trailer Hanger Kit is 29-1/2-inches. You can probably space them the 3/4-inches further apart, to a spacing of 30-1/4-inches, without too much impact on the suspension geometry. However, you may be able to compensate for this change by using longer shackle straps. The shackle straps supplied with the kit are part # 115052 which are 2-5/8-inches long. We offer part # TRSL313 from TruRyde. We...

You will want to measure the shackle straps you currently have. If you have shackle straps that measure 2-5/8 inches center to center you can use 1/2 inch longer shackle straps like part # TRSL313.

  • Suspension Hanger Kit Recommendation for Single Axle Trailer
  • I'd go with a new hanger kit for your single axle Shorelandr trailer like with the part # APS4 so that you get all new mounting hardware that's designed to work together and the correct sizes. This kit is designed for smaller trailers like what you have and includes 3-1/8 inch long shackle straps like the # TRSL313.

  • Should Tandem Axle Trailer Suspension Shackles be Replaced One Axle at a Time
  • I'd recommend doing one axle at a time. Jack the trailer up by the frame on both sides and then jack the axle up to take the load off of it and then replace the shackles. Trying to do both sides at one time will be hard as the components will most likely have tension in them which will prevent them from from easily being removed and reinstalled.

  • Replacement Trailer Suspension Shackle that is 3-1/8 inches Long

  • Replacement Equalizers Measuring Approximately 6 Inches Long x 4 Inches Tall
  • I do have options for you but they would need to be purchased individually as we do not offer an all inclusive kit with equalizers, shackles, and bolts in the size you need. The closest equalizer we have to the provided dimensions is part # TREQ310 which measures to be 6-1/16" from the center of the bottom two bolt holes and 4" from the center of the top bolt hole to the center of the bottom bolt hole. These equalizers work with 1-3/4" wide leaf springs with 9/16" spring eyes. I have attached...

  • Does Shackle Strap Come in Quantity of One
  • The Shackle Strap # TRSL313 does come in a quantity of one, so the price is for each individual strap. For a single axle trailer you will need a total of four shackle straps. I have added a link to a video review of this strap for you to check out as well.

Both of these equalizers are 2-7/8 inches tall. You want to measure the height of your equalizers to make sure they are the same. I have attached a diagram to show you how to measure the height.

  • How To Raise A Tandem Axle Trailer 3 Inches
  • The longest shackle strap we offer is part # TRSL313 which measures 3-1/8" long center to center. In order to replace all of these on a tandem axle trailer you would need eight of them. However, as previously mentioned this will not raise the trailer.

  • Can 2-1/2" Shackle Straps be Used for 2006 Innsbruck-Lite 26RB Suspension
  • When it comes to shackle straps on a trailer suspension it really boils down to what looks correct. Since leaf springs and equalizers can be switched out (especially on older trailers), longer or shorter shackle straps can be used to help make sure everything is lined up correctly (see attached photo). As long as your suspension looks like that photo then it is perfectly fine to use 2-1/2" shackle straps like the part # 115052 which is 2-5/8" long. If your suspension doesn't look like...
