Building a single axle trailer you will need the following items to install leaf springs. I have listed the part numbers for the PR626 Springs next to the items needed.

2 Springs - # e27SR
2 Front Hangers - # 115917, 1-1/2 inch tall or # 28-5, 3-1/4 inches tall
2 Rear Hangers - # 30-20, with 1-1/2 inch or # 93003-3x, with 3-1/4 inch
4 Shackle Straps - # TRSL313
6 Shackle Bolts and Nuts - # 166081

These components are available in the following Kits.

Single Axle Trailer Hanger Kit 1-1/2 inch Tall Front, item # APS1
Single Trailer Axle Hanger Kit for 2K Axles 3-1/4 inch Tall Front, item # APS5

To attach springs to the axles you will need U-Bolts and U-Bolt Plates that match the springs and axles you will be using.

If you are hanging dual or triple axles there are other consideration to take into account such as axle spacing and placement to get the proper tongue weight on the trailer so it will tow properly. Axle spacing will depend on the wheel/tire combination you plan to use and the hubs on the axles. The extra parts needed will be equalizers, center hangers, equalizer nuts and bolts and extra shackle straps, not to mention another set of springs.

Answer 1

For a single axle trailer, you want the shackle strap to be able to move so that you have the spring deflection needed for your suspension. Angled like the photo or even almost vertical is fine you just don't want the shackle strap to bind…

Answer 2

Based on your images it does appear your trailer was built to have double eye springs rather than a slipper spring. For this you will need to measure your current mounts from bolt hole center to bolt hole center. We have the 3,500LB leaf springs…

Answer 3

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. I attached a picture that shows what the angle is typically like.

Answer 4

With slipper springs you will want the eyes of the spring facing the front of the trailer and the open end facing the back. I attached a help article on slipper springs for you to check out as well.

Answer 5

When replacing the leaf springs on your 6 x 12 utility trailer you will need to match all of the dimensions and the spring capacity as closely as possible to the original spring. Usually the measurement from eye to eye will lengthen and the height…

Answer 6

Since you have 3,500 lb axles you most likely currently have 3,500 lb axle leaf springs which we have in a 4 leaf spring with part #e68SR. This is 25-1/8 inches long which is a very common length and most likely your best option. But without knowing…

Answer 7

The leaf spring you referenced part #e54SR would work great as a replacement for your single axle trailer. This is a little shorter than what you have now and is 3,500 lb rated so it would work perfectly. Springs stretch over time as they wear out…

Removing cap nuts like the part #CE10800 requires grabbing the outer flange with a set of pliers to pry open the cap enough how to pull the cap off.

Answer 9

We have a 6 leaf 6,000 lb trailer axle leaf spring with the part #e94SR which would work well for you. It has the higher amount of leaves that you are wanting and is slightly higher rated. This will work great with your EZ flex system as well.

Answer 10

From the measurements you provided, the 6-Leaf Double-Eye Spring #e27SR will be the closest in length we have available. That being said, your current springs do look a bit flattened out, so it will be a good idea to replace all 4 of them with…

Answer 12

When picking out new trailer leaf springs it is important to closely match their length with your existing sets. Leaf springs will definitely stretch/lengthen a bit over time (around an inch or so at most) but the 20-3/8 inch long 3-Leaf Double-Eye…
