You can definitely use wet bolts with leaf spring trailer suspension. The usable length (distance from back of bolt head to beginning of threads), of the part # 126B2 is right at 2-5/16 inches and the overall bolt length (including threads) is 3 inches.

I attached an install video for this bolt for you to check out as well.

Answer 1

I'd recommend the 3-Leaf Double-Eye Spring for 4,000-lb Trailer Axles part #e57SR which measure 25-1/4" long and have a bit more capacity than your standard 3,500 lb spring so they won't wear out as fast. This means you must…

Thank you for providing a photo of your trailer shackle straps showing the extra non-threaded portion of the Redline zerk-fitted bolts #126B2. Shackle bolts are intended to have a fairly loose fit with the shackle straps when installed properly. This…

Good question, and what happens is that leaf springs elongate over time, and since you mentioned you got measurements of 25-1/2 inches from center eye to center eye and 26 inches under partial load, the best option for leaf springs really is the…

If you check out the picture I attached you can see that the knurls of the wet bolts like the part #126B2 are supposed go through the shackle straps and not the bushing. I believe the issue you are having is you are trying to force the knurls through…

Answer 5

Typically a suspension bolt will be measured by the shaft of the bolt not including the head, since the head of the bolt isn't used in mounting the springs. The shackles are 3-3/4" long x 1-1/2" tall overall and the bolt holes are…

Yes, axle spread and wheel base by definition are the same measurements. You will measure from the center of one axle to the center of the 2nd axle to determine what you axle spread is. This may be difficult as some wheels and covers will make this…

Answer 7

The term, wet, in this case means that the head of the bolt has a grease Zerk in it and there is a channel that leads to center of the bolt. This makes it easy to grease the bolt while installed, as you can put a grease gun right up to the Zerk and…

Answer 8

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…

Answer 9

I contacted MORryde and this does happen from time to time as the weight of the trailer can spread out the axles due to downward pressure on the springs/suspension. Odds are the 35" wheel base #MR27ZR will be the correct one for you, but they…

Answer 10

To correctly measure a leaf spring, you'll want to jack the trailer up on jack stands so the axle is hanging freely, then measure directly across from the center of one spring eye to the other, as shown in the provided diagram. The height of the…

Answer 11

Yes, going from a 4 leaf to a 6 leaf spring would add slightly to your ride height. For example, if the current 4 leaf spring has 3/8" thick leaves, and you go to a 6 leaf spring with 3/8" thick leaves, you would be adding 3/4" of…

Answer 12

Well shackle length is mainly based on the height difference between the front and rear hangers. The rear hanger normally doesn't hang as low as the front so that the shackle can offset the difference and add the ability to move. What is the…
