Your picture didn't make it through but it sounds like you are asking about the angle of the shackle strap on trailer leaf suspension. You want leaf spring shackles to be at a slight angle as that prevents the springs from flipping around to the other side of the equalizer over uneven terrain but also let's the spring stretch as it compresses. Typically this is achieved by having the leaf spring just slightly shorter that where it would mount to the hangers/equalizer.

Since the Roadmaster Comfort Ride Leaf Spring Suspension Kit w/ Shock Absorbers # RM-2460-2570 changes the leaf springs you will need to take a measurement from your front hanger bolt hole to the rear hanger bolt hole on your trailer to determine the resulting axle spacing. Once you have that measurement you will subtract the length of the spring 27" to find your approximate axle spacing. Do understand that since the springs compress and push towards each other under load the measurement... view full answer...
The Timbren Silent Ride Suspension Kit # TSR2000S06 will not increase the weight capacity of your Aluma Utility Trailer. This kit will provide you with a smoother and quieter ride than the traditional leaf spring suspension you currently have. The progressive springs will get firmer as the load increases providing a more stable ride. The springs will better absorb road shock and vibration than a leaf spring which will give the trailer a much smoother ride.
There are far less moving parts... view full answer...
The Curved Equalizer for 1-3/4" Wide Double-Eye Springs # TREQE34 that you referenced does not have a weight rating but will be safe to use basically with any trailer leaf spring suspension that has leaf springs that are 1-3/4 inch wide. view full answer...
I have contacted Timbren and for the specific rear suspension kit that you referenced that # TOTTUN4, you will need approximately 6-1/4 inches of clearance between the frame and the leaf spring on your modified 2003 Toyota Tundra vehicle suspension.
I did pull a set of Timbrens from the warehouse and the measurement from the top of the leaf spring to the the top of the Timbren spring is 5-1/8 inches, and if you add approximately 1 inch like you have indicated that will give you approximately... view full answer...
To measure for the correct leaf spring length, you should jack up the trailer so that the axle hangs free, then measure straight across from the center of one eye to the center of the other eye. Because springs tend to flatten out as they wear, this the best way to get an accurate measurement.
Each of our product pages for the leaf springs shows a diagram showing the width and height of the spring.

The torque requirements for leaf spring u-bolts depend on the diameter of the u-bolts that are being used. If the gross weight of your tandem axle trailer is 7,000 lbs, then you likely have two 3,500 lb axles. Typically 1/2 inch diameter u-bolts are used with leaf springs for 3,500 lb axles and they have a torque rating of 45 ft/lbs to 70 ft/lbs.
The shackle bolts do not require a specific torque rating because tightening the shackle bolts too much will squeeze the shackle straps against... view full answer...
There is usually two capacities listed on a leaf spring. The spring capacity and the axle capacity.
For the 4-Leaf Double-Eye Spring # e54SR that you referenced it has a spring capacity of 1,750 lbs meaning that the individual spring can handle 1,750 lbs. The axle capacity is 3,500 lbs meaning that when you use two springs the combined capacity is 3,500 lbs.

I believe you are referring to the 4-Leaf Double-Eye Spring for 2,000-lb Trailer Axles # e77SR.
Since your boat alone weighs in at 1,900 lbs you would want something beefier as the suspension supports the weight of the trailer as well. The best way to choose your leaf springs is to match their weight capacity with that of your trailer axle.
For your situation you would likely need the Leaf Spring # e27SR instead which has a weight rating of 4,500 lbs.
Please be sure to avoid overloading... view full answer...
The center bolt of a leaf spring such as # e54SR is essentially structural integrity. The bolt goes through the leafs and helps ensure stability. If you take a look at the photo I've added you can see how the U-bolts and center bolt of the leaf springs work in conjunction to form the composition of the trailer's suspension. view full answer...
If your trailer has the correct carrying capacity for your pontoon boat and if the trailer's suspension is in good order you may not gain anything by switching to 6-leaf springs. Trailer leaf springs are made with varying numbers of leaves and they are selected based on their specific weight rating which needs to match the axle. Spring length also matter too, of course.
If the springs are rusted/badly worn you may just need new ones of the same rating. The double-eye leaf springs we have... view full answer...

Uneven axle spacing isn't a great sign and most likely is related to the issue. If the leaf springs are the same length and the hangers are spaced differently that would not be the safest setup though and it would be wise to move the hangers to allow you to have even axle spacings.
To prevent leaf springs from braking best option is to make sure you aren't overloading the springs that are installed and that all of the suspension components are installed properly in the correct locations.... view full answer...
The typical spring deflection for leaf springs on a trailer is up to 1-1/2 inches when at capacity.
The recommended clearance with leaf spring suspension on an unloaded trailer is between 2 - 2-1/2 inches between the axle and the frame. You would want an additional 3 inches beyond deflection for maximum bump clearance for fenders and would want 4.5 inches of clearance at the unloaded ride height for fenders. view full answer...
When measuring a trailer leaf spring to pick out a replacement you'd need to measure from spring eye center to spring eye center with no weight on the spring. For example, the Dexter spring part # 072-017-00 would be correct replacement if the axle was a 2,000 lb axle and the measurement was right at 20-1/4 inches. You do need to factor in a bit of spring stretch since they tend to flatten over time. Around 1/4 inch is about correct. view full answer...
The weight rating of the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS3611-YHD for your 2022 Ford F-150 is probably geared more towards payload than towing a trailer because it gives extra support to the leaf spring suspension.
Please note that the weight rating of this system (or any other suspension enhancement) won't actually increase the weight capacity of your pickup, rather it just offers support for that much weight.

The axle capacity for a trailer does double when you add a second one to a trailer. This does not mean the trailer has double the capacity since the frame of the trailer may have the capacity. A trailer's overall capacity is only as strong as it's weakest link. That could be the axles, tires, suspension, trailer frame, coupler, etc.
The best way to pick out leaf springs is to pick a set that matches the capacity for the axles/trailer the best. If you have 3,500 lb axles you would want... view full answer...
Thank you for the photo of your boat trailer suspension.
If your boat trailer's identification plate indicates a gross vehicle weight rating (GVWR) of 3500-lbs for the loaded trailer then I think your springs could be too heavy, rated for too much weight. Your axle may have its own identification sticker or plate that will let you confirm its own weight rating. If the trailer has one axle and it is rated for 3500-lbs then I would suspect you are right that the previous owner installed... view full answer...
We do not recommend that you exceed your trailer's carrying capacity. You will be limited to your axle's rating. The 3-leaf slipper springs, # SP-039275, that we offer measure 24-1/4" long x 1-3/4" wide. These springs are designed for use on trailers with 1,500-lb axles.
If your axles are only rated for 1,500 lbs you would be limited to that.
I have included a link to our 2000 lbs axles and a FAQ article on trailer suspension systems for you to check out. view full answer...
You would not like the ride quality with 6K-rated springs on the 3500-lb axles on your 2003 Dutchmen Lite travel trailer. In fact, since you (wisely) plan to replace all four leaf springs at once just having four new 3500-lb-rated springs will have the trailer suspension feeling stiffer than what you're accustomed to.
The best way to go is to completely remove one of the springs so you can measure its eye-to-eye length without any tension on it. Do note that after years of use leaf springs... view full answer...
