• How to Measure for Replacement Slipper Spring on a Cox Tent Trailer
  A similar leaf spring that we have is the etrailer 2-Leaf Slipper Spring # e29SR which is 30" long and rated for a 1,800 lb axle. The 30" is measured from the center of the eye to the end of the leaf spring (see attached picture). The spring is 1-3/4" wide and has an eye diameter of 9/16" with the bushing. Let me know if this doesn't fit your specs and I can see if we have something else for you.

• Looking for 30-1/4 inch Leaf Spring for Boat Trailer
  Hey Tim, I believe the part # e29SR would be your best option and is only off by .25 of an inch in overall length. It is a 2 leaf slipper spring with a flat end like you want and for a 1,800 lb trailer axle. What is the axle capacity of your boat trailer?

• 4.80-12 Trailer Tires Wearing in Middle Could it be 30 Inch Slipper Springs
  Hi Gary, Yes, it is possible the bounce is causing the issue with your tires wearing out more in the middle. You may try lowering the psi in the tires to help stop the bouncing, or going with a lower-rated tire like the load range B Kenda # AM10060. This has a 785 lb per-tire capacity, and it is important to makes sure the tires have a capacity that meets or exceed the GVWR of your trailer. That can be tough with a homemade trailer, of course, so I recommend weighing it fully loaded to...

• Are Radius End And Flat End Slipper Springs For A Trailer Interchangeable?
  The only difference between the Flat and Radius end slipper springs is the shape of the end of the spring with the radius having an arch and the flat being flat as you can see in the included pictures of the Radius End # SP-179275 and Flat End # e29SR. The springs are interchangeable but you will want to make sure that the length from the center of the spring eye to the end of the spring is the same, and make sure the spring matches the axle rating of the axle on your trailer.

• Replacement Slipper Springs for 1982 Cox Boat Trailer
  Selecting new slipper springs for your 1982 Cox boat trailer's suspension means matching them up to your trailer's axle weight rating and also matching their width and length dimensions. The actual number of leaves does not always matter because different grades of steel can mean fewer or more leaves in a spring for it to reach is rated weight capacity. I think you are on target with the 1800-lbs axle rating for the spring # e29SR you referenced since your 1-1/4-inch diameter axle is not...

• Replacement for 31 Inch Slipper Springs on Small Trailer
  The closest leaf springs we have to what you're describing is part # e29SR. these are 30 inches from the center of the eye to the very end of the slipper end. One thing to keep in mind is your springs are going to be longer than they were when they were new because springs flatten over time. Before purchasing springs you should find out your trailer's axle capacity because the number of leaves isn't an indication of capacity. These springs are for 1,800 pound axles. Also, make sure your...

• Which End Faces Forward When Installing a Slipper Spring
  When installing a slipper spring, like the 2-Leaf Slipper Spring # e29SR, you will install it so that the end with the eye is oriented towards the front of the trailer and the open end is facing the rear part of the trailer. You will need to use hangers when installing slipper springs and avoid shackle straps. Since one end of the slipper spring is open and not "fixed" it will not sit properly if shackle straps are used. I have attached a helpful article that goes into detail about what...

• Replacement Suspension For a Old Trailer With 32-1/4" Slipper Springs and 1-3/4" Axles
  The longest 1-3/4" wide slipper spring we carry is 30" from the center eye hole to end of the flat slipper end. We have springs for 1,800lb # e29SR, 2,900lb # e49SR and 3,700lb # e89SR axles. With your axle diameter being 1-3/4" in diameter it likely is only a 2,000lb axle. All the springs above have a 15" length from center of eye to center of spring pack along the curve. The center of spring to end of spring along the curve is only 17-3/4". If this will not fit your application you...

• Replacement Slipper Springs for 1985 Harding Boat Trailer
  I do have options for you but exact replacements for old boat trailers are hard to come by. In the majority of cases, items will need to be altered for an exact fit which I assume is what is going to need to be done on your trailer as well. We don't have a slipper spring that is 1-3/4" wide x 28" long (center of eye to end of spring) with a 2,500, 3,000, or 3,500 lb capacity. However, leaf springs will fatten out over time which means the leaf spring that was originally installed on the...

• Replacement Slipper Springs to Replace 32 Inch Long Springs
  The 30 inch slipper springs we carry don't have a measured radius but the 28 inches you're looking for will work just fine. Your 32 inch springs were likely a little shorter than that originally and have flattened over time. Although probably not the full 2 inch difference but enough that our 30 inch springs will work on your trailer. We carry three different weight capacities that are 30 inches: 4-Leaf for 3,700 pound axles # SP-040275 3-Leaf for 2,900 pound axles # SP-039275 2-Leaf...

• Replacement Slipper Style Leaf Spring for 1984 Tee Nee Trailer
  For your 1984 Tee Nee trailer, the number of leaf springs is not the determining factor but rather the length and the capacity rating. The 3-Leaf Slipper Spring w/ Flat End for 2,900-lb Trailer Axles - 30" Long # SP-039275 is a great replacement option based on your photo as long as your axle capacity is 2900 lbs because each spring is rated for 1450 lbs. If you have a 3,500 lb axle then instead you would want # SP-040275 because it is a higher weight rated spring. If the trailer axle...

• Replacement Slipper Spring Recommendation to Replace 31 inch Long Spring
  For a slipper spring that would work well for your application you would want the part # e29SR. This is a 2k rated spring that is 30-1/4 inches long. This should be a much softer spring than what you have as it looks like your spring would be a higher capacity than this one.

• Can the 2 Leaf Spring on my 1977 Boat Trailer be Replaced with the 3 Leaf Spring # WIF3
  Over time leaf springs will flatten making them a bit longer than their than their original length. You mentioned that the springs on your 77 boat trailer measure 31-1/2 inches so the 3-Leaf Slipper Spring, # SP-039275, measuring 30-1/4 inches would work as a replacement for your current 2 leaf springs. Part # e29SR that you mentioned is a 2 leaf spring for 2,000 pound axles. Please keep in mind that although you will be increasing the weight capacity of the springs by upgrading to the...

• Replacement Slipper Spring for a Jon Boat Trailer
  When replacing trailer leaf springs you are correct in that you want to do both sides at the same time. You can go a little over in capacity but if you go too much the suspension basically wouldn't function as it would be too stiff to move and absorb bumps. When picking out a slipper spring the most important dimension you need to get from your old springs is the length of the spring when measured from the center of the bolt hole to the other end of the spring. The 2-Leaf Slipper Spring...

• How to Find Replacement Slipper Spring for Jet Ski Trailer
  The length of the slipper spring is from the center of the eye to the end of the slipper. See the attached diagram below. The width and the capacity are also necessary when choosing a replacement, leaf count isn't very important and can vary. The capacity will be based on your axle. For example, if you have a 30" long slipper spring that is 1-3/4" wide and a 1,800 lb axle you could use the # e29SR. I have attached a link to all of our slipper springs along with a helpful article on slipper...

• Will Overrated Slipper Springs Cause Rigid Ride
  The 30" 2-Leaf Slipper Spring for 1,800-lb Trailer Axles # e29SR may well improve your ride, it just depends on what your axle is rated for and what your current springs are rated for, though it seems likely a 4-leaf spring is rated for more than you need. Ideally you are going to want your springs to be rated the same as your axle, or as close as possible without going under. The 30" # e29SR you referenced have an 1,800 lb axle capacity (900 lbs per spring), which is the lightest for...

• How To Find the Correct Replacement Leaf Spring for an Old Row Boat Trailer
  In order to find out what trailer leaf spring is correct you will need to measure from the center of the eye to the end of the other side while there is no weight on the trailer.

• Replacement Trailer Suspension Components
  In a typical leaf spring trailer suspension a spring seat like # TRSS300 is welded to the axle but the u-bolt plate is not. The u-bolt plates are bolted around the axle and leaf spring and these hold the spring in place on the spring seat and to the axle, as noted on your photo. You can also refer to the linked article on slipper spring suspensions for more on the details of how these parts work together and on how to measure. You'll want to completely remove one spring from the suspension...

• Slipper Spring for Older Boat Trailer that is 30 inches in Length
  We have a few slipper springs that are 30 inches from spring eye to hook, but you did say eye to eye which would imply a double eye spring. Since 30 inch double eye springs are very uncommon I'll assume you do have a slipper. So for a 1,800 lb capacity spring you'd want the part # e29SR or for a 2,900 lb spring you'd want the # SP-039275.

• Replacement Slipper Springs for a 2,100 lb Trailer
  The most important factor in picking out a new leaf spring for a trailer is to match the capacity needed. Going with a 3,500 lb spring for a 2,100 lb trailer is going to give you a very harsh ride. For a spring similar to the # WIG4 that is better rated for your trailer we have the # SP-039275 which is for a 3,000 lb axle or part # e29SR for a 2,000 lb axle. If you need all 2,100 lbs of your trailer's capacity you would have to go with the # SP-039275. If you have a 2 inch square axle...
