Leaf springs

When you are buying make sure if the weight rating is for a single or for a pair. If each spring is rated at 3500pounds then a pair will support 7000 pounds which would be plenty. If it says that a pair supports 3500 pounds then I would buy heavier springs. Marketing can be very tricky.

I just came up with a similar question so will jump in on this thread if ok.
Last year put on new axel, wheels, brakes, rims, etc. due to the lost wheel episode. Well this weekend I had trailer on blocks and tires off to do some general clean up and maintenance on belly. I noticed top inside of wheel wells have been rubbing at times....a little shiny spot. Then I noticed, after lowering with tires back on that space between frame and axel is only about a strong inch and it too shows signs of occasional hitting. So, I’m guessing new better springs is the fix? Do I just measure spring length when off trailer and go with something rated higher than the 3k ( loaded) of the trailer)? Are there other options to gain height with the springs? Thanks.

This is a reminder that any time you change Springs, tires or any other suspension parts you should always measure the distance between the high point on your axle and what ever it would hit to stop it's travel. Then measure from top of tire to wheel well, next subtract axle travel measurement from total clearance and I recommend at least 2" of clearance. This allows for wheel angle changes when one wheel travels more than the other when hitting uneven places. Tires hitting the wheel is not only bad for the tire but can cause the trailer to start leaking and or allow pest a path to enter.

Thanks. Axels are over spring a so I guess blocks wouldn’t work. On longer shackles, would it be both ends, or just the end that pivots. Welding required?. Seems new springs aren’t all that expensive if that by itself would work with just heavier duty—-or not worn out. Is re arching less costly. As far as tires, I can go from the 90 to 75 and gain an inch in wheel well, but it won’t help on axel too close to frame.

Thanks for the input.

I’m going to try to get it weighed when we get everything installed. I’m going to leave the stock axle. Seems like the older stuff is built so much better than new Chinese stuff. I’ve been trying to estimate what I think it would weigh just by what I’ve installed right down to estimating 5 pounds of screws to 30 pounds of butyl tape. I’m thinking 4000# springs should be a no brainer. As far as ride height, I’m putting 15 inch 205s on and I have around 1 1/2” from the wheel well top. I’m hoping new springs will get me another 1/2”. I’m going to put new brakes on but not going to use them if possible. Brakes on vehicles are so much better than they were in 1965 so I’m hoping I won’t need them but going to put them on just because they are cheap to purchase and I’ll already have the axle torn apart.
