My old u bolts and leaf springs were rusted through so bad I had to cut them off. I had such a hard time finding replacement parts for my little boat trailer with such a small 1 1/2 inch axel. This was exactly what I needed! Fit perfectly with my New 24 5/8 x 1 3/4 inch leaf springs. 844361

Completely updated the axle, suspension, and added roller bunks to my waverunner trailer. Have taken the waverunner in for the winter and back out for the summer one time. All components were great and the trailer rides really well! 794372

Works great, personally the u bolt itself could be a little larger diameter. I stripped one of the nuts because I tightened it too hard also. But was just hand tightening. 790093

Exceeded my already high expectations. I live in rural Hawaii and my complete boat trailer axle down to tires was delivered within a week of order with reasonable shipping charges.. Local place gave me runaround 3x already. This saved me. Now I can go fishing again! Dimensions and sizing can be difficult, even if you are used to these things but trailer makes it super ez.. With videos and detailed things. Thank you, I will definitely do business again!!! 782577

  • Replacement U-Bolts Compatible with CE Smith U-Bolt Kit for 1-1/2 Inch Square Axle
    The CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles - 3-3/8" Long U-Bolts - Zinc # CE23102 unfortunately doesn't have direct replacement parts outside of the kit. The Replacement U-Bolt with Nuts for 1-1/2" Wide, Square Trailer Axles - 1/2" Diameter # 1753223 is the closest we have to what you are seeking but it is not zinc plated and is 5 inches long.

  • Can Round Trailer Axle be Replaced with Square Trailer Axle
    Yes, you can replace a trailer's round axle with a square axle as long as the weight capacity is appropriate. You will need a new U-bolt kit to connect the axle: 1-1/2 inch square axles # CE23102 1-3/4 inch square axles # 175130 for the U-Bolts and # 116308 for the plate 2 inch square axles # CE23103

  • How to Determine Correct Slipper Spring Replacement for 1,500 lb Axle
    What happens to slipper springs is that over time they elongate and flatten out, particularly if your springs are considerably older. The most important measurement you mentioned was the 26 inches from the center of the spring eye to the end of the spring. Based on that the closest slipper spring we have that could work is the 3-Leaf Slipper Spring w/ Radius End for 1,500-lb Trailer Axles - 24-5/8" Long # SP-178275, which would work if you had a tandem-axle trailer. There are no slipper...

  • Replacement 1-1/2 Inch Square Axle for a Boat Trailer
    I do have some options for you but none of our trailer axles match the exact measurements that you provided. Therefore, the best option we have for you would be to switch to an axle less system like the Timbren Axle-Less Trailer Suspension System part # A20RS545 which will replace the axle, leaf springs, and leaf spring hangers in light of a rubber suspension system that works to absorb road shock and support the trailers load better than standard leaf springs. The other option you...

It has the hub-face-to-hub-face length of 57-1/2 inches and the spring-center-to-spring-center length of 46-1/2 inches with the overall beam length of 62 inches. The only thing that you will need to change is the spring centers which is just a drilled hole for the square axles. There will be a difference with the...

  • Recommended Slipper Spring for Custom Kayak Trailer
    Thanks for the photos with measurements. The 2-Leaf Slipper Spring w/ Radius End for 1,000-lb Trailer Axles - 24-5/8" Long # SP-177275 are rated for 500lbs each for use with a 1000K axle. This will work with the inside to inside measurement you are seeking. You will simply need the 9/16 inch bolt # 166079. If there is any extra space in the hanger it won't be an issue with the bolt and bushing.

  • Recommended Jet Ski Trailer Leaf Spring U-Bolt Mounting Kit for 1-1/2 Inch Square Axle
    Recommended U-bolt Kit for square 1-1/2 inch axle and # SP-113275 springs is the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles - 3-3/8" Long U-Bolts - Zinc # CE23102. This will work much better than the u-bolt that is simply used diagonally in your current photos. These are plates are galvanized and the hardware is zinc plated so they are ideal for your Jet-Ski trailer as they resist rust and corrosion.

  • Replacement Leaf Springs for Harbor Freight Folding Trailer
    The best option we have for you is the 3-Leaf Double-Eye Spring part # SP-169275 with the Single-Axle Trailer Hanger Kit part # APS4. This option will replace the leaf springs and leaf spring hanger brackets which is needed because the new double eye leaf springs are 1-3/4" wide and the old slipper springs are 2" wide not to mention the length discrepancy and leaf spring hanger bracket height. The CE Smith U-Bolt Kit for Mounting part # CE23102 or part # CE23103 can then be used to complete...

  • Recommendation For Replacing Leaf Springs And Hangers
    I am glad to make a recommendation for your needs based on the pictures and information you sent. We have a few options to consider for a 30 inch long leaf spring that is 1-3/4 inches wide. For an 1,800 lb axle that has 2-Leaf Slipper Spring with flat end option, you would use Item # SP-038275. For a 2,900 lb axle that has 3-Leaf Slipper Spring with flat end option, you would use Item # SP-039275. A U-Bolt Kit for a 1-1/2 inch wide square axle for 1-3/4 inch springs is Item #...

  • Recommended 26 Inch Double Eye Springs for 1-1/2 Inch Square Axle Compatibility
    The 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles - 26" Long # SP-053275 are way to strong a spring for your 1-1/2 inch square axle. Typically 1-1/2 inch square axles have a capacity between 1000 and 2000 lbs. I recommend instead using the 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long # SP-124275 which will match the standard capacity without making the ride too firm adding to bounce. Don't worry about the number or leaves but rather the capacity rating. I...

  • Replacement Axle Tube for a Habor Freight Model 90154 Trailer
    In order to determine if we have a new axle beam that will work for you, we would first need to do some measuring. The measurements that will need to be taken are from the center of each spring seat on the axle you have now as well as the distance between the two hub faces. I have attached a photo of this for you as well. The most important measurement that you need to verify is the hub face as the spring seats can be moved. For example, if you have a hub face of 60" you can then use...

  • Switching From Slipper Springs to Double-Eye on a Single 2K Axle Trailer with Square Axle
    To switch to double-eye spring suspension I recommend getting parts individually since the u-bolts cannot be swapped out of kits. The spring in the kit is # SP-169275. We have a few different u-bolt kits for square axles including # CE23102 for 1-1/2 inch square axles. For a 1-3/4 inch square axles you can use u-bolt # 175130 and plate # 116308. And for 2 inch square axles we have # CE23103. You will also need a new hanger kit since double-eye springs use different hangers than slipper...

  • Recommended Options for Height Adjustment on 1,800 lb Axle
    You can mount the CE Smith Trailer Axle w/ Idler Hubs - 5 on 4-1/2 Bolt Pattern - 57-1/2" Long - 1,800 lbs # CE33201GA-HUB in an overslung axle position. You will simply need to use a U-bolt kit like # CE23102 but with longer U-bolts. We unfortunately do not have that hardware but you will want the bolt plates for 1-3/4 inch springs.

  • Are Trailer Spring Seats Needed for Square Axles with Leaf Springs?
    Square axles normally don't have spring seats like a round axle but do have a hole for the leaf spring bolt to fit into. Take a look at the CE SMITH # CE33201GA-HUB for a visual. The U-bolt mounting kits will have a hole in the center for the other side of that leaf spring bolt to keep everything in line. If you have a 1-1/2 inch square axle use # CE23102. If you have a 2 inch axle use # CE23103.

  • Compatibility of 3500 lb Double Eye Springs on 1-1/2 Inch Square Trailer Axle
    The 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 25-1/8" Long # SP-212275 would be a little firm if you are hauling the trailer without a snowmobile, but with one or more it would be fine. The additional weight capacity of the spring will not enhance your trailer's overall capacity. This is because you would still be limited by the weakest part of the system very likely your axle. I recommend using the CE Smith U-Bolt Kit for Mounting 1-1/2" Square Trailer Axles - 3-3/8" Long...
