What Might Cause Trailer Leaf Spring to Break Top Leaf  

The only real difference between your current 3-leaf springs and the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles - 27" Long #SP-210275 will be the thickness of the leaf spring stack. This will be 3/8" thicker when compared to what…

Every 3,500lb Dexter axle we sell has a diameter of 2-3/8" and typically uses a 5-1/2" U-bolt, such as U-Bolt Kit for Mounting 3,500-lb, Round Trailer Axles - 5-1/2" Long U-Bolts #APUBR-1. You may have a 5,200lb Dexter axle, which has…

Hello Monte, thanks for reaching out. Both of the springs you mentioned, the etrailer #e54SR and Dexter #DX23CR are springs for a 3,500 lb axle. The difference is the brand and the length. The #e54SR is our etrailer brand and is 25-1/8" long eye…

Those are some good options, and the best overall upgrade (without getting too crazy like you said!) for your Jayco with tandem 3,500 lb axles is going to be the MORryde CRE3000 with the X-factor crossmember. The Road Armor is good, but the…

Hey Dennis, thanks for reaching out! The 4-Leaf Double-Eye Spring #DX23CR has a 3" drop from center eye to middle of the leaf spring (see attached photo). For a single axle setup I recommend the Hanger Kit #APS4, and for a tandem axle setup I…

Hey Mike, thanks for reaching out. Yes, we should have the leaf springs and hardware you need, but those parts aren't make and model specific to your trailer, so I will need a bit more information from you. For the leaf springs, I'll need to…

Hi Austin, I can help you determine the right replacement double-eye leaf springs for your 2018 Jayco trailer, though we don't have any way of knowing what specific ones you need. It's pretty easy though, as all you need to do is measure your…

Hey Eli! The first thing you want to do is make sure you have brake flanges on those axles. You also need to take a look at the axle tags and find the axle capacity. More than likely they're 3,500 lb axles so I'll answer based on that. If you…

Hey Duane, The Hellwig kit you referenced was designed for trucks and would not work for your trailer but we can still help. What you'd want instead is the SumoSprings kit part #TSS-106-40 which is for lighter duty trailers with underslung…

You can use leaf springs that are rated higher than the axle without any issues as long as they measure the correct measurement for your trailer. For example the 6-leaf double eye spring for 7,000 lb axles part #e64SR measures 24-7/8" eye to…

Hello Ryan, thanks for reaching out. Yes axle U-bolts are not meant to be re used so you will definitely want to replace them. For a 3,500 lb 2-3/8" diameter axle, the longest we carry are the 5-1/2" U-bolts like what come with the #APUBR-1…

Hey Kevin thanks for your question. There is not much downside to going with the 5,000 lb springs instead of the 3,500 lb. A higher rated spring may make the ride a bit more "chunky" at times, since the spring would not flex as easily.…
