• Do Roadmaster Comfort Ride Leaf Springs Require New Bushings
  Hey Dave! The Roadmaster Comfort Ride Leaf Spring # RM-2460-2570 comes with bushings. The only thing you will need is the existing bolts from your trailer. Some people do decide to go ahead and swap their existing bolts out for wet bolts # 34007-187-00 if you don't already have them. What kind of trailer do you have? As long as you have a 3" diameter axles this kit will work for you.

• Replacement Leaf Springs for 2017 Grand Design Imagine 2600RB
  Thank you for providing that information. Leaf springs like the ones you have now typically match the axle capacity on your trailer. Although adding leaf springs with a slightly higher capacity won't hurt, it also is not necessary. Based on the leaf springs and and other information I'm sure you have 3,500 lb axles. Your standard diameter for this capacity would be 2-3/8". In addition to the capacity you want the eye to eye length to match, so we are looking at 25-1/4" long leaf springs. I...

• Dexter EZ Flex Equalizers for 6,000 Pound Axles on a 2006 Heartland Bighorn 5th Wheel
  The length is good on the EZ Flex system # K71-653-00 but the height may be different depending on where you are measuring that 4-3/4 inches. On the EZ Flex the distance from the center of the mounting hole to the center line between the 2 bottom holes, straight up and down, is 2-7/8 inches. If your 4-3/4 inch measurement is diagonal then you will be good to go with this kit. For a u-bolt kit you can use # APUBR-9. The shocks might actually feel more effective with the EZ Flex kit installed....

• Torque Specs for U-Bolt Kit for Mounting Axles
  It depends on what u-bolts you are using. The torque specs for 9/16" diameter u-bolts like the U-Bolt Kit for Mounting 5,200 lbs to 7,000 lbs, Round Trailer Axles item # APUBR-9 will be a range, from 65 ft lbs to 95 ft lbs. If the tie-plates start to bend inside this range that would be definitely be a stopping point.

• Upgraded Suspension Parts for 5th Wheel Triple Axle 5200 Pound Axles on 2006 Eclipse Attitude 33aks
  Hello Ken. For upgrading your suspension on your 2006 Eclipse Attitude 33aks I recommend starting with the MORryde Suspension Upgrade Kit for Triple Axle Trailers - 3-1/8" Long Shackle Straps # MR26ZR. There isn't a data base that I can reference because there isn't an industry standard when they are putting the 5th wheels together, with that being said you are going to want to double check the measurements on your current shackle straps that they are 3 1/8" from center hole to center...

• What is Length Measurement of 7-Leaf Double-Eye Spring DX74XR
  I checked directly with Dexter, and from what I saw they have a measurement - taken from center of spring eye to center of spring eye - of 24.8", which is the same as our 24-7/8" measurement for the 7-Leaf Double-Eye Spring for 8,000-lb Trailer Axles # DX74XR. The only reference to 25.25" I saw was from a different retailer, and maybe they were talking about the overall length, but it is not the correct center eye to center eye length. As for the U-bolts, yes, a 7k Dexter axle and the...

• Recommended Roadmaster Comfort Ride For A 2022 Vanleigh Beacon 5th Wheel With 8K 3" Axles
  Since you have 8K 3" axles you'll just need the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks - Tandem 8K, 3" Trailer Axles # RM-2460-2580. The 3-1/2" requirement you were getting with the # RM-2470-2580 was simply because of the shock kit. I do recommend replacing your U-Bolts as well though with ones like # APUBR-9 as these get stretched and worn out after being torqued down and could potentially cause an issue down the road. These U-Bolts fit a 3" axle with 1-3/4" or...

• How to Determine Correct Replacement Slipper Springs
  In order to find the correct replacement slipper spring you will need the length, width, and the capacity. The leaf count does not indicate capacity and is not important when determining a replacement. This information would also make a difference in the mounting hardware. For example, the 4-Leaf Slipper Spring w/ Open Eye End # e24SR is 27" long, 1-3/4" wide, and designed for 4,300 lb axles. Assuming a single axle, you could use the # APS3SE and # APUBR-1 (this is for a 2-3/8" diameter...

• Will the 8K Roadmaster Comfort Ride Leaf Spring Suspension Kit Work With 7K Axles
  The Roadmaster Comfort Ride Leaf Spring Suspension Kit part # RM-2460-2580 will indeed work on 7,000 lb axles. The leaf springs would just be slightly overrated for what you need but there will be no problems with compatibility. It does require that you un-bolt the u-bolts so we recommend replacing them at this time using the U-Bolt Kit part # APUBR-9.

• How to Determine Correct Replacement Leaf Springs for 7,000 lb Axle
  I can give you some guidance on how to determine the correct replacement leaf springs, and you are right that replacing all four of them at the same time is a good idea. What you'll need to do for double-eye springs (which is what I assume is on your 2017 Keystone Fuzion) is measure from the center of one eye to the center of the other eye and get a match as close as you can. Just take into account that the springs may have elongated a bit over time. For example, the only double eye spring...

• Replacement 7,000 lb Leaf Spring & Mounting Hardware
  The 7,000 lb double-eye leaf spring we have that is closest to 26" is the 24-7/8" long 6-Leaf Double-Eye Spring for 7,000-lb Trailer Axles # e64SR. Assuming yours have flattened a good amount (which will definitely be true if the trailer is older), these will work out as a good replacement. You mentioned hardware, and I'm assuming you were referring to U-bolts, shackle bolts and straps. You'll need to measure your shackle straps but you can use the following: - U-Bolt Kit # APUBR-9 -...

• Recommended Roadmaster Comfort Ride for a 2020 Grand Design Momentum 320G
  Jon, it actually looks like you'd be needing the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shocks # RM-2460-2580 instead. These are for 8k axles, which from my research, is what your 2020 Grand Design Momentum 320G has. This kit will include everything you need for install, but we do recommend upgrading the U-bolts to longer ones # APUBR-9.

• Recommended Equalizer, Leaf Spring, and Hardware for 2005 Weekend Warrior Suspension System Upgrade
  For your upgrade in trailer suspension on your triple axle Weekend Warrior toy hauler I recommend the E-Z Flex Triple Axle Suspension Kit with 7-3/4" Equalizers # K71-657-00. This kit comes with all the equalizers and hardware you need. Then you will use the 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # e94SR and I recommend upgrading your axle u-bolts to the # APUBR-9. You will use the following quantities: 1-E-Z Flex Kit 6-Leaf Springs 3-U-bolt Kits This update...

• Replacement 9/16 U-Bolt Kit Options For A Dexter 7,000-LB Axle
  The U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles # APUBR-8 that you mention will fit just fine on your Dexter 7K axles, however these U-bolts are only 1/2" thick. Since you mentioned that you are wanting 9/16" thick U-bolts, I recommend taking a look at the: -U-Bolt Kit for Mounting 5,200-lb to 7,000-lb, Round Trailer Axles # APUBR-9, which measures 7-1/16" long, Or the, -3" Round Trailer U-Bolts 9/16" Diameter # SP01-080 with the U-bolt plate # 117521-G, which...

• Hanger Kit Recommendation for a 6K Axle on a Tandem Trailer
  There are two spring options that would work for you, the part # e46SR that you referenced or the 5 Leaf Spring part # e34SR. The only difference is that the # e34SR is a multi-leaf spring with a 100 lbs more capacity than the # SP-115275. Either would work fine for you, I would go with the # e34SR just because of the additional capacity, and with a multi-leaf spring if a leaf fails your trailer wouldn't be completely un-usable. You would be able to limp home to fix the trailer. The Tandem-Axle...

• Replacing 3,500LB Trailer Axles With 6,000LB Axles On 42" Wheelbase Travel Trailer
  On an axle like the Dexter Trailer Axle w/ Electric Brakes # 35545E-ST-89 the maximum overall overhang(hub face to spring center distance) is 18" total. That will put your current axle 2" past the maximum with having an 89" hub face and 69" spring center. A 5,200lb Axle # e75SR will only allow for a 19" overall overhang, so you will need to move to a 6,000lb Axle # e65SR as it allows for a 20" overall overhang. This will require you to move to the 6 lug wheels. With the MORryde 14-3/4"...

• Can a Dexter 5,200 Lb Axle Be Replaced With a Dexter 6,000 Lb Axle
  It sounds like you are asking if you can use the Dexter Trailer Axle Beam part # 8327826 to replace the axle beam included with Dexter Trailer Axle with Electric Brakes part # 8327816-EB and reuse the braking assemblies and hubs/drums. If that is the case then yes you can as the diameter of the spindle where the bearings and grease seal ride are the same. Therefore, even though they may use a different outer bearing, the diameter for the inside of the bearing where it sits on the spindle...

  Hey Addison, the trailer hitch replacement leaf springs part # e44SR does not come with u-bolts. We have U-bolt kits that would work though like with the part # APUBR-9.

• Will I Need New U-bolts If I Go From A 4-Leaf To A 6-Leaf Spring?
  Hello Ken. I am not sure exactly how long your current U-bolts are, but you will probably be able to re use them. It just depends on how long they are and how much thread is left. Assuming your 4 leaf spring has 3/8" thick leaves it would be 1.5" thick. The # e94SR 6 leaf spring is 2.25" thick so as long as you have another 1" or so of threads left on the current U-bolts they can definitely be re-used. If you find you need something longer, we have the U-Bolt Kit # APUBR-9 which comes with...

• Recommended Slipper Spring And U-Bolt Kit For Trailer With 7,000 Lb Axle
  We have just what you are looking for. The slipper springs we offer for a 7,000 lb axle are part # e74SR. This is a 5-leaf spring that measures 26-5/8 inches long and 2 inches wide. It is always recommended to replace both sides of the trailer suspension at the same time to make sure they wear evenly and support the trailer evenly as well. You can check out the attached photo with the dimensions noted for the leaf spring. When checking the dimension of the spring you will want to check...
