Features to know about

Enduring Strength for Heavy-Duty Use: 1/2-Inch Thick Steel Shackle Straps

When you're hauling with a single axle trailer, you need suspension parts that can endure the load. Enter the Dexter Heavy Duty Suspension Upgrade Kit: boasting 1/2-inch thick steel shackle straps that promise longevity by replacing the flimsier standard shackle straps. Built from sturdy steel, these massive components are designed to support trailer loads ranging from 3,500 lbs to 7,000 lbs without missing a beat. It's a straightforward way to prevent the wear and tear that can lead to premature failure, ensuring your suspension performs well over the long haul.

Smooth Sailing Across Rough Roads: Wet Bolts with Built-In Grease Zerks

Ditch the creaks and squeaks. The wet bolts included in this kit come with grease zerks for fast and easy lubrication. This design ensures that all moving parts operate smoothly, reducing noise and making for a quieter, more pleasant towing experience. Plus, with simple periodic maintenance (just a little grease every now and then), you'll extend the life of your suspension components significantly.

Precision and Durability: Bronze Bushings and Steel Bushings Combination

Upgrade from nylon bushings to rugged bronze bushings for your leaf springs, providing an unbeatable combination for longevity and precision. Unlike nylon, bronze bushings paired with steel bushings are impervious to harsh conditions and offer a perfect fit that doesn't degrade over time. Experience a flawless ride with every journey, knowing your trailer's suspension remains accurately aligned and tightly secured.

Easy Installation: Quick Setup with Comprehensive Kit

Why struggle with complicated installations? This Dexter kit makes it simple to enhance your trailer’s suspension. The comprehensive kit includes everything you need: locknuts, wet bolts, steel bushings, and shackle links. Say goodbye to the headache of sourcing parts individually—this streamlined approach allows for quick installation, letting you spend less time in the garage and more time on the road.

Optimize Weight Distribution: Double Eye Springs Adaptation

For trailers with double-eye leaf springs, this suspension upgrade kit expertly supports the weight of heavy loads. The design aids in maintaining consistent suspension height and optimal weight distribution across your trailer's axle, avoiding undue stress on individual components. Whether hauling a boat or snowmobile, you'll benefit from balanced performance and heightened safety with every trip.

Consistent Performance Over Time: Enhanced Greaseable Bolts and Shackles

Dexter’s upgraded shackles not only boost durability but provide a system that keeps everything running smoothly for miles on end. With greaseable bolts ensuring continued operation without binding or pull, these shackles prevent the pitfalls of traditional setups, keeping your trailer’s suspension in prime condition with minimal maintenance required.

  • Recommended Shackle Straps and Hangers for a Single Axle Trailer
    I would be happy to help but first you will want to take some measurements of the hangers and shackle straps you currently have to determine which ones you'll need. Longer or shorter on the shackle straps and hangers will change the ride height of your trailer. The Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers item # K71-358-00 would work great with the 5-Leaf Double-Eye Spring item # e34SR you're purchasing. The included shackle straps have a length from center of...

  • Recommended Shackle Upgrade Kit for a Dexter D35 Axle
    It looks like the D35 axle is a 3.5K axle so the Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00 should work fine, you'd just have to measure your current shackle to verify. These shackles measure 4-5/8" long x 1-1/2" wide x 1/2" thick, and measures 3 1/8" between the center of the bolt holes. If your shackle measures different, let me know what that is, and I'd be happy to find you the correct kit.

  • Can a Single Axle Boat Trailer Be Switched From a Slipper Spring Suspension to Double Eye
    To switch to a Double Eye Spring # e48SR you would need to also change out your Rear Hanger # 30-20 since you will be adding Shackles # K71-358-00. This is required since the rear hanger has to be 1-3/4" wide on the outer versus at least 1-3/4" wide on the inner like you get with a Slipper Spring Hanger # CES83FR for a Slipper Spring # e33SR.

  • Heavy Duty Shackle Kit for Lippert 4,400 lb Axles
    For a heavy duty shackle kit that would work well on your 4,400 lb axles we have the Dexter HD shackle kit part # K71-358-00. These shackles are really thick at 1/2 inches.

  • Dexter E-Z Flex Suspension Kit For 2008 Jayco Triple Axle 5TH Wheel Camper
    The Dexter E-Z Flex Suspension Kit # K71-657-00 is a universal suspension kit but you will need to confirm a few measurements on your 2008 Jayco 5th Wheel to ensure a proper fit. First this kit is only designed to work with double eye leaf springs that are 1-3/4" wide. The equalizers in this kit are designed to replace equalizers that are 7-3/4" wide for the short equalizer and 8-3/8" wide on the long equalizer. They are 2-7/8" tall and use shackle straps that are 2-1/4" from hole center...

  • Why Does Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers Only Come with 4 Bushings
    Great question, Brian! The bushings that fit on the bolts for the shackle straps tend to wear out a bit faster than the ones that connect your leaf spring directly to a hanger which is why there are only 4 bushings in the Dexter Heavy Duty Suspension Upgrade Kit for Single Axle Trailers # K71-358-00. If you wanted to get 2 additional of the bushings that come in this kit then the part # D014-077-00 is the exact same bushing so you just need to order 2 of them as well.

  • How to Determine Replacement Hub Assembly for PacWest Utility Trailer
    It looks like PacWest has a number of different utility trailers with different capacities. In order to determine if the # AKIHUB-550-35-K will fit you are going to need to identify your axle or check your bearings. Assuming you have a 3,500 lb axle, more than likely this will fit. You could check your axle tag for identification and call PacWest or you could use your VIN number. The other option is to pull off your existing hubs and see which bearings you have now. The part number is...

  • Will The Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00 Work On a 2,500LB Axle?
    Yes, the Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00 will fit your single axle trailer with a 2,500lb axle. This kit is a standard universal size which is designed for double eye springs. We do have it listed for 3,500lb-7,000lb axles but it will still work on lighter axles.

  • Does Dexter Make A Complete Shackle And Wet Bolt Kit With 3-1/8" Long Shackles?
    The only 3-1/8" shackle kit we carry from Dexter is the # K71-358-00 which is for a single axle trailer. If you are in need of a complete kit for a tandem axle trailer, we recommend the MORryde Suspension Upgrade Kit # MR76ZR. This will come with very similar 3-1/8" HD shackles, bronze bushings and wet bolts just like the Dexter kit. The equalizers are sold separately, and we have many different sizes available depending on what you are needing. We just want to make sure a replacement...

  • Replacing Slipper Springs Incorrectly Installed on 18' Boat Trailer With Double Eye Leaf Springs
    Based on your images it does appear your trailer was built to have double eye springs rather than a slipper spring. For this you will need to measure your current mounts from bolt hole center to bolt hole center. We have the 3,500LB leaf springs which will provide you with enough capacity. We have them in a 23-1/8" # e59SR, 25-1/8" # e68SR or 27" # e97SR length. You will want to select the spring length slightly larger than your mounting bolt pattern. You will need the Suspension Kit #...

  • Replacement Leaf Springs for 2022 KZ Sportsmen Classic 191BHK
    Finding the correct replacement leaf springs requires measuring their length and knowing your axle capacity. It would be great if I could confirm replacement parts based on the year, manufacturer, and model but unfortunately it doesn't work that way. You can get the length of your leaf springs by measuring spring eye to spring eye, and your axle capacity from the tag on your axle. I have attached an article below which shows how to measure your leaf springs. You may also be able to get...

  • Replacement Double Eye Leaf Springs For a Single Axle Trailer With Hangers Spread 25-3/4"
    Sorry for the confusion but with the mounting brackets for your single axle trailer being separated 25-3/4" on center you will need to use a 26" leaf spring. We offer this length leaf spring in a couple different weight capacities. 4,000LB Axle # e22YR 4,500LB Axle # e27SR 6,000LB Axle # e94SR I do recommend upgrading your Shackles # K71-358-00 when installing the new leaf springs.

While the length does not have to match exactly you will want it as close as possible to maintain your current ride height.

  • Replacement U-Bolt Kit, Leaf Springs, Bolts and Shackles for 68 Aristocrat Lo Liner Trailer
    Installing the U-bolts and plate like that would be fine, but I would recommend putting the plate on the leaf springs and running the U-bolts around the axle instead. The good news is you're replacing them so you can make that change when you install them. Once you have your axle measurements we do have some kits you could use. If it is a 2" square axle the # CE23103 or for a 1-1/2" square axle the # CE23102. If it is 1-3/4" you will need the # 175130 along with the # 116308. Since you...

    We can get you the right shackle kit for your single axle trailer with a Dexter 3,500 lb axle, and you can choose from either a standard kit or an upgrade kit. Either will work, though the Upgrade Kit is going to be the best option due to the fact it includes thicker 1/2" shackles, wet bolts with grease zerks to make lubrication super simple, along with bronze bushings for the longest lifespan.

  • Parts Needed To Convert a Single Axle Jet Ski Trailer To Double Eye Leaf Springs
    The main issue you are going to have Dan is the rear spring mount is designed for allowing a 1-3/4" wide spring to sit inside the mount. You will need 2 different Rear Hangers # 93003-3X which allow the shackle bolts to mount on the outside of the hanger and be wide enough for the 1-3/4" double eye springs you will need. I recommend going with 2 of the 3-Leaf Double-Eye Springs # e84SR, the rear hangers above and the Wet Bolt Kit # K71-358-00.

I recommend bronze bushings like the # D014-077-00 or for the 4 pack the # K71-291-00. We also have nylon bushings available # 721590. If you're looking for an entire hardware upgrade kit like the old Lippert kit we have those as well. For a single axle trailer you could use the Dexter Heavy Duty Suspension Upgrade Kit # K71-358-00.

For the sake of consistency though I do recommend using the Step Wet Bolt # 34007-187-00 with the Flange Nut # 006-092-01 as opposed to the Wet Shoulder Bolt # LC126238.

  • How Tight Should Shackle Strap Bolts Be
    The shackle bolts used between the springs and hangers do not require a specific torque rating because tightening the shackle bolts too much will squeeze the shackle straps against the leaf springs, and the whole suspension system will bind and cause problems. The best thing to do when tightening down shackle bolts is to use lock nuts, tighten them until they are snug, then back them off 1/4 turn. Lock nuts should be used because they resist loosening with vibration or torque. The part...
