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..

This is a multiple product review. The long bracket are good. The shorter brackets are of the same good quality. The issue is using the short brackets with the shackles. The shorter brackets could be narrower so the shackle line up better with spring and other longer bracket. We used washers to make it align better. The greasing bolts are good, but could be longer. so we could only use 2 of the 6 and had to use normal grade 8 bolts. 720770

  • Dimensions of TRSL313 Trailer Suspension Shackle Strap
    As you can see in the photo I've edited for you, the # TRSL313 measures 4-1/2 by 1-1/4 inches. The center hole to center hole spacing is 3-1/8 inches and the bolt holes themselves are 9/16 of an inch in diameter.

  • 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...

  • Thickness of TruRyde Shackle Strap # TRSL313

  • 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.

  • 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...

  • 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 6k Rated Leaf Springs with Cushioned Equalizers for Tandem Axle Trailer
    The 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles # SP-053275 that you referenced will work great on your trailer as it matches the capacity you need. The overall thickness of the spring pack is 2-1/4 inches which might be thicker than what you current have and could affect the height of the trailer. For a U-bolt kit you would need the part # APUBR-8 which is for the 6k axles like you have. The equalizers you have now are Equa Flex Cushioned equalizers so for a replacement set...

  • Why Are Shackle Straps Hitting Frame When Re-Building Trailer Suspension
    The problem seems to be mostly that your shackle straps are hitting the frame, and the reason for this is almost certainly because the 3-1/8" Shackle Strap # TRSL313 you are using are too long. The other possibility was the hangers being too short but that is unlikely considering the lengths you gave. What I recommend is trying out the 2-5/8" shackle straps from the the # APT8 kit you have, as those are the typical length for a tandem axle trailer, while 2-1/4" straps such as # TRSL225...

  • Cushioned Equalizer with Bolts and Shackle Straps for 2018 Diamond Cargo Enclosed Trailer
    For the Equa-Flex Cushioned Equalizers # LC279688, the manufacturer lists the Lippert Components Tandem Axle Equa-Flex AP Kit - Wet Bolts - 3-1/8" Long Shackles # LC64FR as a related kit and that would be my recommendation. This is a great option, but you can alternatively use regular bolts like # TRFA73Z916DLNZ or wet bolts # 126B2 which will work better than the regular bolts. Then use regular shackle straps # TRSL313.

The shackle straps of that length we carry are 1/4" thick, the Shackle Strap - 3-1/8" Long # TRSL313. With these you would need the Never Fail Bushing # LC281625 and Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # TRFA73Z916DLNZ. So for thicker shackle straps, you would have to source them...

  • 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...

    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...

  • 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...

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.

  • 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.
