item was a perfect fit for a 2008 Heartland Cyclone. the measurements on description were a big help. Would definitely buy again.




by:

I’ve been rebuilding trailers for many years and was very happy with the service and quality of parts




by:

This is a great kit at a good price. Huge improvement over what my rv came with. No more worries




by:

Fit great, arrived quickly




by:

I havent installed the kit yet but i have installed another kit abour 5 years ago. I am very pleased with the product. The shackles are twice as thick as previous. These new ones also have the bronze bushings installed with the 12 bronze bushings for my springs. Would recommend to another customer. The shipping was expedited efficiently and timely. Arrived quickly for regular free shipping. Thanks . Probably looking at buying 3 axle disc brakes from etrailer shortly.




by:

Awesome package!! I don't know why trailer manufacturers don't use the best when they build them. Everything fit perfect period way stronger than original equipment. Nice to be able to grease fittings no more nylon to wear out.




by:

The order delivered was on time. However, being shipped all the way across the country and being a heavy package — the packing box was beat up and one small I item was lost. So I call the main number and talked to a company rep— looked up my order and they had the missing item in the mail that day. I received the part two days later. They were very professional and nice people to do business with. Thanks




by:

This seems to be like a much improved system over factory. Heavier and everything is greasable.




by:

Great service,rep was very helpful,kit installation was simple,a much better product than what came on the trailer




by:

Quick shipping, products as described

  • Length of Equalizer 013-105-04 in Dexter Heavy Duty Suspension Kit # K71-360-00

  • Could the Dexter Heavy Duty Suspension Kit K71-360-00 be Used with 34 inch Axle Spacings
    The # K71-360-00 is designed for use as a replacement equalizer kit for a triple axle setup with 33 inch axle spacings. That being said, if your leaf springs happen to be 1 inch longer and have a 34 inch spacing this kit would work too. The most important factor is that your leaf springs are 1-3/4 inches in width.

  • How To Determine Correct Leaf Spring Hanger Spacing for the Dexter Heavy Duty Suspension Kit
    In order to determine the correct leaf spring hanger locations on a trailer you first need to position the axles correctly. I have attached a help article on this part of the process for you. Then, once the axles are correctly positioned you can then mock up the suspension using the equalizers, shackle straps, and leaf spring. The mock up should then give you a good idea where your leaf spring hangers will sit but I cannot provide specific measurements on the Dexter Heavy Duty Suspension...

  • Will Dexter Suspension Kit # K71-360-00 Fit Raptor Fifth Wheel Trailer with 33 in Axle Spacing
    Yes, the Dexter Heavy Duty Suspension Kit # K71-360-00 that you referenced will work great for you since you have 33 inch axle spacings. This is a kit for triple axle trailers that have 1-3/4 inch wide springs that are spaced 33 inches apart.

  • Determining If Dexter Heavy Duty Suspension K71-360-00 WIll Fit 2008 Heartland Cyclone Toy Hauler
    It is very possible that the Dexter Heavy Duty Suspension Kit # K71-360-00 you were looking at will fit your 2008 Heartland RV Cyclone 5th Wheel Triple Axle Toy Hauler, but to confirm this you will want to measure the length of your existing equalizers and shackle straps. This kit includes one equalizer that measures 5-3/4" between the two horizontal mounting holes on center, and another that measures 7" as shown in the included diagram. The included shackle straps measure 2-1/4" between...

  • Where Does Third Axle Normally Install When Adding Axle to Tandem Axle
    The best axle location will be the location that allows the tongue weight of the trailer to be between 10 and 15 percent of the total trailer weight. We realize that's really hard to determine in your current situation since the trailer isn't built yet, but I did attach a link to a page that has info and formulas to help once you get to a place where you can place the axles. In general though when adding a third axle to a tandem the two axles would need to be moved forward a bit. A great...

  • Is 34" Axle Spacing Okay for the Dexter Axle Suspension Kit # K71-360-00
    The Dexter Heavy Duty Suspension Kit # K71-360-00 is designed for 33" axle spacing. Since your current spacing is 34" this kit should fit just fine with your current hanger spacing. I have attached a picture showing what this kit should look like once installed. If you are wanting to get precise with your fit and measurements then I would need to know the length of your leaf springs (center-eye to center-eye) when your trailer is unloaded as well as the weight capacity of your axles.

  • Will Adding a Third Axle to A trailer Affect Its Tongue Weight
    Assuming that the way the load is distributed on the trailer isn't changing, adding the third axle shouldn't have much of an effect on the tongue weight. It will however better disperse the weight of the trailer down to the ground, resulting in less wear and tear on the suspension and running components like wheels, hubs and bearings assuming that the load on the trailer isn't increased.

  • Recommended Heavy Duty Suspension Kit For Triple Axle Toy Hauler W/ 33" Axle Spacing
    You are right on. Since you have 33" axle spacing and 6000lb axles on your triple axle toy hauler I recommend the Dexter Heavy Duty Suspension Kit # K71-360-00 as it was designed to work with trip axle trailers with 33" axle spacing and axles up to 7000lbs each. The # K71-360-00 may ride a little rougher than your current setup since you are wanting to get away from the cushioned equalizers, but will give you the strength you are looking for.

  • How Many Spring Hangers Needed for Tandem Axle Trailer
    A tandem axle trailer would use a total of 6 spring hangers, three per side. The help articles I've linked for a Double-eye and a Slipper Spring suspension will explain more in detail about the components that make up a trailer suspension system.

  • Why Would Trailer Suspension Shackles Flip Upside Down When Axle Drops
    If your shackles and equalizers are flipping upside down that would indicate you have either too wide of hanger spacing or you have equalizers that are too short. The easy solution will be to get the dimensions of your equalizer to me so that I can pick you out one that is slightly long and will make it much harder for the shackle to flip. I attached a page that has all of the equalizers we offer for you to check out. The lengths of them are organized on the filters on the left of the page.

  • What Causes Trailer Suspension Equalizers to not Sit Level
    The amount of tilt I see in the pictures you submitted of your equalizer isn't too bad. That could easily be from the trailer not sitting perfectly level. If the trailer is level and it's still tilting this can be solved in one of three ways. You either go with shorter leaf springs, a shorter in width equalizer, or you move the rear and front hangers out about half inch.

  • Determining If Dexter Heavy Duty Suspension Kit Will Fit A 2005 Weekend Warrior Superlite FS 2300
    It is possible that The Dexter Heavy Duty Suspension Kit # K71-360-00 will fit your 2005 Weekend Warrior Superlite, but you will have to measure the length of your existing equalizers and shackle straps to 100% determine if it would work. The equalizers in the kit mentioned above are 5-3/4 inches between the two horizontal mounting holes on center and on the other one measures 7 inches between the two horizontal mounting holes on center.

  • Tandem Axle Suspension Kit for 2018 Keystone Hideout with Tandem Axles
    I checked out your 2018 Keystone Hideout trailer and it has a tandem axle setup so for a similar kit to the one you referenced you'd want the part # K71-359-00 instead as this is a tandem axle setup from Dexter that matches the Dexter setup you have now that has shackle straps that are 2-1/4 inches long. I attached an install video for this kit for you to check out as well.

  • Proper Loading of Triple Axle Trailer to Minimize Sway
    The fact that your modified trailer has a third un-braked axle added in front of the two braked axles will not directly affect sway. Nor will the fact that it seems to balance pretty well on its own without a load. Trailer sway, or the lack of it, is mostly a function of load distribution. If the loaded trailer is too light at the tongue (too heavy at the rear) the rear of the trailer will tend to swing like the pendulum on a grandfather clock. Tongue weight (TW) should always stay in...

  • 3rd Axle Addition on Fifth Wheel Toy Hauler
    You can absolutely add a 3rd braking axle to your trailer. You will simply want to match your current axle for dimensions and capacity. I've linked the page to your options we carry to assist. Then you will need to change your hanger locations so, I recommend using the Triple-Axle Trailer Hanger Kit for Double-Eye Springs - 1-1/2" Front/Rear, 2-1/2" Center # APTT3 and I've attached a help article to assist with the placement. The leaf springs you need will depend on the axle capacity...

  • Recommended Lift Kit for Adding 2 Inches of Height To Tandem Axle Trailer
    There are two alternatives available, one that's a sure thing and one that's a possibility, depending on the current height of your spring hangers. The Lippert # LC407131 Tandem axle lift kit will bolt right up, providing almost 2 inches of additional lift with no welding required. Depending on the current height of your front, back and center spring hangers (measure from the center of the bolt hole that secures the spring to the underside of the frame member where the hangers mount)...

  • Could Universal Group Leaf Spring SP-053275 Fit a Heartland Cyclone
    When picking out leaf springs for a trailer priority one is the proper capacity. If you have 6k axles on your Heartland Cyclone then the 6-Leaf Double-Eye Spring # SP-053275 would fit and work well as a replacement. The hanger kit part # K71-360-00 would then work well with this spring as well. If your older springs were worn out and sagging because of that these would eliminate the sag. Since these springs are a little bit thicker the trailer would sit up a bit taller if the springs...

  • Comparing Dexter Heavy Duty Suspension Kit and Triple-Axle Trailer Hanger Kit
    The Dexter Heavy Duty Suspension Kit part # K71-360-00 has bronze bushings and wet bolts whereas the Triple-Axle Trailer Hanger Kit part # APTT3 has nylon bushings and standard bolts. The bronze bushing resist wear more than nylon and the wet bolts make for easy maintenance. The two kits are cross-compatible.

This will mean a possible change in the length of your shackle straps. These are the proper width and are 4 leaf springs capable of a 2,000 lb capacity individually or 4,000 lbs per axle.

  • Leaf Spring and Hanger Kit Recommendation for 7k Triple Axle
    We have one double-eye leaf spring that has a 7,000 lb axle rating. For that you would want the part # e64SR. The hanger kit you would need then to go with that is the Dexter Heavy Duty kit part # K71-360-00. The axle spacing will be 33 inches which is pretty close to the dimension you listed but short by 3-3/4 inches.
