Video Transcript for TruRyde Accessories and Parts TRSL313 Review

Today we're going to be taking a look at the TruRyde shackle strap. This shackle strap connects a double-eye spring to the rear hanger of a single axle trailer or equalizer of a multi-axle trailer. The connection allows movement to take place, ensuring an evenly distributed load between the axles. This strap is made from a steel construction. One shackle strap is included. A few measurements to go over with you real quick.

We're going to take a measurement from the center of 1 hole to the center of the other. That's going to give us a measurement of 3 1/8 of an inch. Overall measurement from edge to edge is going to be about 4 3/8 of an inch long. Overall width measurement from edge to edge, that's going to measure about 1 inch and 1/4. The thickness is not quite 1/4 of an inch.

I put a caliper on here, a digital caliper and got 0.222 of an inch. Then the bolt hole diameters are 9/16 of an inch. That's going to do it for today's look at the TruRyde shackle strap.

Great products for a good price and fantastic service. I will be using etrailer again. I broke one spring on my tandem axle trailer. After a little internet search I found etrailer. I decided to change all springs(upgraded to p4)shackles,equalizers,n bolts) total price around $200.00 about 40 percent cheaper than a local trailer repair shop..I ordered it early on a Tuesday and I got the order on Wednesday. Changed out parts on Thursday and back on the road on Friday. Great company to deal with!! 78016

I was so happy to be able to order the exact replacement shackle straps for my RV suspension system. This monster wasn't moving again until the repair was made. etrailer offered my replacement strap at a great price with fast delivery. Let's not forget excellent customer service, helpful videos and detailed product descriptions to ensure you get the right part the first time. Thank you etrailer staff for your excellent customer care. I'll be back when the need arises. Ed 362698

Being a machinist I can tell you these are stamped on hydraulic press with way to much force and dull dies to boot. The holes are already half way worn out. The die side of the punch is the correct size 0.565 - 0.570, but the bottom side of the hole, metal is blown or torn away 0.585 - 0.590 with not enough metal left to maintain the hole size. The knurl on the bolts barely digs in. I have to rate these some what poor! 191898

I replaced the equalizers, shackles, bushings, bolts, and nuts on an old trailer. Everything fit properly without modification. Product quality was excellent. 264421


No problems to date. A coat of primer keeps the corrosion under control.

Service, order submission, order processing and shipping was very prompt and professional. Parts were better quiality and I'd expected at this price. The enitre process was a very pleasant one and I've added a link to etrailer in my favorites so that I can become a return customer. Other companies could take a lesson from etrailer. 44938

These shackles installed easily and were the exact same dimensions as the ones I replaced. The shackles are solid and appear to be sturdier than the ones I replaced. Ordering with etrailer was easy as they provided all the dimensions needed to order the correct shackles. Delivery was fast as well. 407209

Received the equalizer a little after lunch today. Had the passenger side of the trailer done in about an hour after some choice words getting the old one off. Putting this in was simple, and should make a good ride and stop wearing my tire out. 328097

The trailer only had one shackle strap from the factory and the bolts had room for a second one. So the originals wore out a lot sooner. These will last longer with one on each side of the leaf springs. 58897

  • What are the Proper Components Needed to Install the Leaf springs On a Trailer
  • Building a single axle trailer you will need the following items to install leaf springs. I have listed the part numbers for the PR626 Springs next to the items needed. 2 Springs - # SP-256275 2 Front Hangers - # 115917, 1-1/2 inch tall or # 28-5, 3-1/4 inches tall 2 Rear Hangers - # 30-20, with 1-1/2 inch or # 93003-3x, with 3-1/4 inch 4 Shackle Straps - # TRSL313 6 Shackle Bolts and Nuts - # 166081 These components are available in the following Kits.

  • 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...

  • 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...

  • Recommended Shackle Straps or Hanger Kit for Single Axle Trailer
  • We have some kits like the Single-Axle Trailer Hanger Kit for Double-Eye Springs - 1-1/2" Front, 7/8" Rear # APS1 and the Single-Axle Trailer Hanger Kit for Double-Eye Springs - 3-1/4" Front, 1-1/4" Rear # APS4. 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...

  • 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...

  • 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...

  • Replacement Equalizer for Desert Fox RV with Tandem Axle Trailer
  • We do not offer equalizers that measure 7-1/8 inches long and 4 inches tall, but we may have a solution for you. Based on your information, you can use the TruRyde 4 inch tall triangular equalizer # TREQ310. This equalizer measures 6-1/16 inches long and 4 inches tall. 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.

  • We currently have two shackle straps that will fit the CE Smith U-Bolt part # CE15502A. For this you can choose from the Shackle Strap part # TRSL313 or part # 115208GALV. 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...
