• Can I Replace 4 Leaf Springs With 5 Leaf Springs For The Axle On My Trailer
  
• Yes, you can replace your 4 Leaf Springs like part # SP-221275 with 5 Leaf Springs like part # SP-111275 as long as you replace all of the springs at the same time. There really isn't any advantage if you want to go with 5 leaf springs over 4 leaf springs. Typically, you always want to try to get the same parts to replace what you already have, but 1/8 of an inch difference per leaf spring won't make much of a difference in how everything fits together. The 5 leaf springs will work just...

• Replacement Parts to Rebuild Trailer Suspension on 1976 EZTrail
  
• All of the products you listed will work together just fine. Keep in mind, if your current springs are not 26 inch springs, like the # SP-124275 you referenced, your hangers, # APS4, will not be in the exact same position as your current ones. When repositioning everything the most important factor is keeping the axle in the same location it currently is. The U-Bolt Kit # APUBR-10 is correct for a 2,000 pound axle and the Shackle Bolt # 166081 will work too. It's hard to tell by the...

• Bolts Needed To Install Slipper Springs
  
• For the spring eye you would use the Spring-Eye Bolt with Locknut for Slipper Springs - 3-1/2" Long # 166079, but slipper springs don't have the second spring eye, so a bolt is not used on the back end. You can also use a wet bolt like # 126B2, for less friction. The Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # 166081 are for use with the spring and shackle straps used with a shackle straps on a tandem setup with an equalizer but it could be used for the springs and the...

• Comparing Bronze and Nylon Bushings for Trailer Suspension
  
• It really just depends on what you are looking to get out of the bushings. Bronze bushings, like part # K71-291-00, will last longer but are more noisy and it is recommended to use wet bolts like part # 126B2 to keep them lubricated. Nylon bushings, like part # SP05-060, are much quieter and can be used with regular bolts like part # 166081 since they don't need to be lubricated as much. As far as lifespan goes the bronze will last longer but not so much longer that they are much better...

• Trailer Suspension Kit and 6 Inch Long Equalizers for Tandem Axles and Double Eye Springs
  
• Suspension kit # APT4 for tandem axles with double eye springs has 6-1/4 inch long equalizers so it is a possible option for you. Kit # AP233-H248 uses 5-3/4 inch long equalizers. But if you have to have equalizer # TREQ310 then the individual parts will have to be pieced together since there isn't a kit with that equalizer. If you go that route then you would also need: 8 of # 18-11GALV 14 of # 166081 1 of # H248 (or other hangers, see link)

• Recommended Shackle Bolt for 2,000 lb Utility Trailer Leaf Spring Suspension System
  
• The Zinc Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # TRFA73Z916DLNZ is a grade 5 bolt. Your setup as described is a standard setup for leaf spring hangers and double eye leaf springs. The # 166081 is made by the same manufacturer and is used more commonly than zinc plated for most factory applications. The cost difference comes down to supply and demand. The Dexter bolt # 007-003-01 is simply a different manufacturer that has a big name in the trailer axle market. ...

• How to Pick Out Replacement Leaf Springs for 2007 Weekend Warrior Model CR3905
  
• I was able to find out that your 2007 Weekend Warrior model CR3905 is triple axle trailer with a GVWR of 16k. That means for each axle you'd need a capacity of at least 5,333 lbs. Which means you most likely have 6k axles. We have a few options for that capacity for leaf springs but you'll need to measure the length of your current springs to be sure. If you have 25-1/4 inch long springs you'd need part # SP111275. If you have 26 inch long springs you'd need part # SP-053275. If...

• Equalizer/Hanger Kit Recommendation with Equalizer TREQ356
  
• We can piece together an equalizer kit for you, however the TruRyde Equalizer, # TREQ356, is not included in an equalizer kit or a hanger kit. Next, you will need 14 shackle bolts that are 3 inches long and have a 9/16 inch diameter. For this, you can use Shackle Bolt, # 166081. Finally, you will need 8 shackle straps. The most common size is the 2-5/8 inch shackle strap, # 115052. I recommend measuring your current shackle straps to verify you are buying the correct replacement...

• Recommended Axles, Hubs, And Springs For 1971 Aristocrat Landmark 1 Trailer
  
• Based on the information and measurements you gave me, I recommend the Dexter Trailer Idler Axle Beam with EZ-Lube Spindles - 72" Long - 2,200 lbs, # T20BTR-EZ-7258. Then we need to add the hub assemblies and for those I recommend the Dexter Axle Trailer Hub Assembly for 13" to 15" Wheels - 2,200-lb Axles - 5 on 4-1/2 - L44649 Bearings, # 8-258-5UC1. The leaf springs to go with these I recommend are the 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles - 26" Long, # SP-124275....

• I recommend using the Never Fail Bushings - 9/16" Inner Diameter, 11/16" Outer Diameter - 1-3/4" - Qty 14 # LC279685. For 1-3/4 inch springs you will want the Shackle Bolt with Locknut for Double-Eye Springs - 3" Long # 166081. There is no specific torque rating for shackle bolts, you simply want to ensure they are long enough so you have at least 2 thread protruding from the bolt. You want to tighten the bolt until the knurls go through the shackle link or hanger and the bolt head is...

• Replacement Bushings, Eye Bolts, and Shackle Straps for a 1-3/4 Inch Wide Leaf Spring
  
• The prices are a reflection of factors such as demand, availability, cost, and several other variables. The nylon bushings are also the least cost effective component of the kit. Unfortunately, we do not offer the Never Fail Tandem Axle Suspension Upgrade Hardware Kit for Double Eye Springs part # LC281285 with 1-3/4" long bushings. If you have 1-3/4" wide leaf springs then you will want to piece your own kit together with the Never Fail Bushings part # LC279685, Shackle Bolt with Locknut...

• Double Eye Spring Recommendation and Suspension Parts for 6,000 Lb Trailer Axle
  
• The leaf spring I recommend is 6-Leaf Double-Eye Spring for 6,000-lb Trailer Axles part # SP-053275. These leaf springs come with 9/16" diameter nylon bushings installed. The amount of leafs do not matter as much as long as the spring is rated for your axle capacity. I recommend TruRyde Shackle Link part # TRSL225. The shackle straps are 2-1/4" long. The bolts you need are part # 166081. I also recommend curved equalizers part # TREQ356 that measure 6-1/8" long. We do not carry an equalizer...

• Hangers to Use with Leaf Spring SP-212275
  
• The spring you ordered # SP-212275 would work well with the hangers # 115917 and # 30-20 with shackle straps # TRSL350. These parts are very similar to what comes with the # APS1 which is what is recommended with the springs you ordered. Only thing else you might need is the shackle bolt part # 166081. The distance between the hangers would need to be 24-7/8 inches.

• Can Replacement Shackle Bolt Have Longer Thread Length
  
• I do understand your concern with the potential of a slightly longer thread length on the Shackle Bolt # 166081 causing the shackle strap to sit right on the threads. The fact is though that the shackle positioned there as opposed to the unthreaded shank is not going to cause much of a difference, if any. The shackle straps should not wear down any quicker because of this. As long as the bolt's overall length is correct then this will work perfectly for your trailer.

These bolts have the zerk fitting to allow you to add grease for better movement and less noise. If you prefer basic bolts, then I recommend # 166081.

• Comparing Lippert Never-Fail Bushings to the Bronze Bushings and Wet Bolt Option for Tandem Axles
  
• The bronze bushings and wet bolts are a great option but they still do require maintenance especially under the conditions you referenced. There really isn't any new information in comparing it is basically the difference between maintenance required and zero maintenance. The Never-Fail bushings # LC279685 are maintenance free and self-lubricating so they will be a better fit for you. This kit comes with the bushings for 4 springs and two equalizers for a complete tandem axle trailer....

First you would want the part # TREQ356 as an equalizer. You would need two of them. A quantity of 8 of the shackle straps part # TRSL225 14 of the bolts part # 166081

• Comparing Wet and Dry Shackle Bolt Strength Rating
  
• A wet shackle bolt like the Redline # 126B2, the type that is hollow with a grease zerk fitting for lubrication, is just as strong as the dry (solid) type like # 166081. Neither variety of this part actually carries a weight capacity rating since the trailer weight is distributed across many of them.

• Replacement Leaf Springs, U-Bolts, Shackle Straps, and Hardware for Three 7,000 Pound Trailer Axles
  
• When replacing springs always replace them in pairs (2 springs per axle) but if you are going to replace all 6 then that is even better. When measuring a spring you have to do it with the weight off of the spring by either removing the spring or jacking up one side of the trailer and measuring on that side. The reason I bring that up is because the double-eye springs that we have do not have the exact measurements that you have provided. Spring # SP-198275 is a close option. Eye...

• 3,500 lb Leaf Springs and Hanger Kit Recommendation for a Mobile Home Trailer
  
• Mobile home axles/suspension are typically designed for one time use, so picking out components to work with mobile home components can be tricky. Your best bet is to do what you did with your axles and just start over with quality stuff that you will know will work. First let's start with a spring. For a 3,500 lb spring the part # SP-212275 would be a great choice. For a u-bolt kit you would want part # APUBR-1. For a tandem axle hanger kit you would want the part # APT3. The Never...

• How Tight to Get Boat Trailer Leaf Spring Shackles
  
• There is no specific torque rating for shackle bolts. You'll want to ensure that the bolts you use are long enough so that when installed you will have at least 2 threads protruding from the nut. Make sure that the bolt you're using has a lock nut, like part # 166081. If the bolt you are using has knurls at the bolt head, tighten the bolt down until the knurls go through the shackle link or hanger and the bolt head is flush. Then back off the nut slightly so that all of the components...

• Can Standard Shackle Bolts Replace Stepped Shackle Bolts
  
• The Step Wet Bolt # 34007-187-00 is a 9/16-inch diameter overall and 3-inches long. The threaded portion is a smaller 7/16-inch diameter (which is the "step"). You can use this part with the matching 7/16 nut # 192600 or you can use standard non-stepped 9/16-inch bolts like # 126B2 (which has a grease zerk fitting) or part # 166081 that does not.

• Recommended Torque Specs for 9/16 and 1/2 Inch Trailer Suspension Hardware
  
• If you will be using 9/16 inch fasteners then torque them down to 110-114 foot pounds. If using 1/2 inch torque them to 76-78 foot pounds. You can find all sorts of different torque specs for the same size bolts or nuts and they will all be around these same figures. If you use Loctite use the blue kind, such as # LT37643, which will allow you to remove parts using hand tools. The red kind is going to be too strong.
