Perfect product. Easy to install as long as you make sure that the trailer is well supported before banging old shackle bolts out and new ones in. Do not try to hammer the new sleeves into the spring eyes. Use a large C clamp. One of the pre-assembled shackle bolt units was slightly bent, not noticably so, but had to use some heat to install the matching plate. 758743

The parts were all the right ones and most were Dexter oem parts. The only problem I had was putting the bolts in the frame end of the spring perch. It was easier to take the spring loose from the axle, put the bolt in ,then bolt it back to the axle. I intend to buy all of my future trailer parts from etrailer. 749785

Yesterday I completed the install of the Dexter Heavy Duty Suspension, kit # K71-448-00. The included instructions were pretty good, plus I watched a few YouTube videos before beginning the install. The biggest issue was removing the old bolts from the trailer. Once that was accomplished the new parts went on easily. Now my suspension just looks stronger and with the wet bolts it should last the life of the trailer. The old plastic bushings were pretty well shot and were overdue for replacement. Thanks to etrialer for a great upgrade! 720585

I've had a few sets of shackle straps wear out. While replacing them I noticed that the bolts and bushings were badly worn. The equalizer also had heavy wear in the center bolt hole. I decided to replace all of the lighter duty parts with this Dexter heavy duty suspension kit. These shackle straps are much heavier and all of the bushings are bronze. These are also wet bolts, so I'll be able to keep them greased and prevent wear. The parts came in a kit together and were easy to install. Shipping was fast and etrailer honored the lowest price pledge by refunding me 110% of the difference between their price and the advertised price of another seller. I definitely recommend this kit from Dexter and etrailer as the right place to get it. 822905

I finally got around to installing the Dexter suspension kit today ( having received it over a month ago ). Installation went very smoothly. The product looks MUCH better than the stock components that were on my Jayco trailer. I believe the capability to routinely lube the pins will make a big difference in performance and longevity. I've ordered many items from etrailer over the years and they did a great job at delivery with good pricing. 816961

Overall I’m very pleased with this heavy duty suspension kit. It fit correctly and I’m sure this wet-bolt system will be much more durable than my old dry-bolt system, which at 4 years old was showing major wear, rust, and fatigue. The reason I gave it only 4 stars was because one of the nuts stripped out under very little torque, as if it hadn’t been heat treated and hardened. The bolt was fine. I reinstalled one of my old nuts and it torqued fine to 50 ft. lbs., per Dexter specifications. All other parts were fine. 811661

Great product, great price! Included all the hardware to replace everything that wears in the spring suspension. Made a loose, very worn trailer like new. Also the bushings are greaseable now so should stay that way. 722349

Ask the Experts about this Dexter Axle Trailer Leaf Spring Suspension

  • What is the Weight Rating on the Dexter Heavy-Duty Suspension Kit
    The weight capacity for the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers part # K71-448-00 is really going to be determined by the spring and the tires on the trailer they don't have a specified weight rating. It is for use with 1 3/4" wide springs so let's take the 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles - 24-7/8" part # SP-198275 this spring is rated for 3500 lbs. and is used on 7000 lb axles.

  • Why Does the Dexter Heavy-Duty Suspension Kit K71-448-00 Come with Silver Bolts and Not Black
    The Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers part # K71-448-00 has zinc plated wet bolts which are just as strong as the black bolts you are used to seeing. The metal is the exact same but the coatings are different. The zinc coating is more durable as it resists rust and corrosion better which is why Dexter is now starting to transition from the black bolts to the silver zinc plated bolts. The Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers is a fairly new kit...

  • Upgraded Heavy Duty Shackle Kit with Bronze Bushings for Tandem Axle Trailer
    For a heavy duty replacement shackle, bolt, and bushing kit for a tandem axle trailer similar to what you referenced but without the equalizers you'd want to order a quantity of two of the part # K71-358-00 for your trailer and you'd be set.

  • Recommended Replacement Suspension for 6K Tandem Axles
    Thanks for the measurements. I recommend using the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275. Then use the Curved Equalizer for 1-3/4" Wide Double-Eye Springs - 6-1/8" Long - 9/16" Center Hole # TREQ356 and the Never Fail Tandem Axle Suspension Upgrade Hardware Kit for Double Eye Springs # LC281285. If you prefer a heavier duty assembly with wet bolts, then use the Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers - 1-3/4" Wide Double-Eye Springs...

  • How To Choose the Correct Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers
    I don't have any information as to what leaf springs are on any one particular trailer such as a 2007 Jayco Jay Flight 29BHS but if they are double eye leaf springs which are the most common then we should have a Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers that will work. In order to choose the correct one you just need to make note of the equalizer dimensions; part # K71-449-00 for 7-3/4" long, part # K71-448-00 for 6" long, or part # K71-359-00 for 5-3/4" long.
