have not had time to install the product but i will say i have NEVER had such excellant service as this bar none the person i talked to on the phone made sure i had the correct part for my trailer reasonable prices is there any reason to shop anywhere else 639726

Just general poor quality Chinese manufactured. Bought 6. On initial grease after install, zerk fitting pulled out of two out of the six. IF you are going to order these, I would in the future plan on buying screw in zerk fittings, tapping these bolts, and then installing screw in fittings. These are worthless as is. I'm concerned that the poor quality and fitment of the zerk will make these more liable to get moisture inside the bolt, increasing rather than helping the potential rust issue in the bushings. Furthermore, splines are too long, so plan on either grinding off portion of the splines or using a washer or two provided you have enough length on the bolt. Great idea, executed very poorly. 144207

Bought these bolts to replace the factory rusted out bolts on my leaf springs and equalizer, they are great bolts and the larger threads and larger nut at the end make for a super easy install. The factory bolts have a stepped down threaded end which makes it hard to install sometimes. 597316

We upgraded our camping trailer last fall so I’m no longer in a position to do a follow up review. Sorry, but the parts worked great while we owned it and gave piece of mind on the road. Thanks again for the parts and service you folks provide, you’re top notch in my opinion!

I bought a set of these bolts to replace the hardware in the triple axle suspension of my toyhauler. I had read about the benefits of a wet bolt kit, and after finding two broken shackle plates on my camper, decided I too needed to be able to properly lubricate the moving parts. These were a perfect fit and replacement for my original bolts. At the time I installed them I hadn't read about orienting the hole in the bolt to the 3 or 9 o'clock to ease pumping grease through them. I put them in at whatever orientation they were in my hand, but had no problem pushing 3 - 4 pumps of chassis grease through the zerk. I was able to observe grease flow out of the spring eyes around every bolt, and all of the zerk fittings stayed firmly in place when I wrestled the grease gun nozzle on and off. There were a few bad reviews about these press on fittings falling out, but I didn't see any evidence of that. I am very pleased with this purchase, and enjoy the peace of mind that comes with knowing I can properly service my suspension and hopefully extend the life of all the components in the system. 302285

This is a tough call. The Good: The bolts are strong and exactly the right size for my Equa-Flex suspension. I was only able to complete one side of the camper before we left for a weekend trip. Even so, I could already tell that side of the suspension was MUCH quieter. I just completed the other side. The Bad: I had read of some complaints regarding the bolts not allowing grease to flow completely through. I have used at least 30 so far and only one appears to have that issue. But that's one too many. My biggest issue is the zerk fittings on many of them will pull out with the greatest of ease. That does not leave me with an extreme amount of confidence. The zerks don't screw in. They just push in. But some can almost come out by hand. Some of them would pop out under the pressure of the grease gun pumping grease inside. My advice: Get these bolts to keep your suspension happy. But buy several more than you need because 1. some will fail you right away and 2. you'll feel better having some on hand if you show up at a campground somewhere and you discover a big empty hole in the head of one of these bolts where the zerk should be. I have six that will stay in the camper at all times for just such an issue. 394539

I used these "wet" bolts on my leaf spring change out. I ended up using 3 per equalizer since that seems to be the location of most of the movement during axle travel and a friends 5th wheel had 3 installed on the factory set up, so that is what I went with. I painted a yellow mark on the head of the bolt in reference to the grease hole in the shaft, so that I could install them in the direction of "least resistance" when greasing them later, after reading how some guys have to relieve pressure on their trailer in order to get the bolts to take grease. I used Mystik 6 grease mixed with anti seize when putting everything together, then gave them 2 shots of Mystik 6 after installation. (I chose Mystik 6 because we always had good results with that grease when I was in the aircraft industry and it doesn't was out.) I did notice that the grease zerks did allow grease to return out of the fitting which means the spring behind the ball isn't doing its job. That is why I rated them as "good". There are different ways to install these due to the knurled shoulder. If you have access to an impact gun you can just tighten them in with that. Pulls the knurl right in to the shackle. Overall I like the idea of having a suspension that can be greased. 167548

Its nice to have wet bolts for people who will take the time to do preventative maintenance on their campers. But these aren't that great. As mentioned in my initial review, the zerk fittings are not tight at all. Most of them will easily pop out when you remove your grease gun. Then you have to try to tap them back in without getting any dirt or debris in the bolt. The zerks are just tapped into the bolt and the fit isn't very good. Next time, I will either go with regular bolts and Never Fail bushings or try to find a different brand. 513394

Not as nice to use as the shouldered style bolts. Requires you to tighten then back off to get the proper clearance. One bolt showed up unthreaded and the grease fittings fell out of a few during installation. I replaced the grease fittings with some better quality ones. ( press in style ) Overall it is a bolt and it is nice to be able to grease the bushings. Make sure you mark the bolt heads with the clocking of the grease hole. I like to install the grease hole on the loaded side of the bushings. Makes the grease go in harder but it gets where it needs to go. I did install a washer behind the nut too. The nut ran out of threads but there was still too much clearance between the spring eye and bracket for my liking. 458473

Ask the Experts about this Redline Trailer Leaf Spring Suspension

  • Correct Track Alignment Replacement Hanger Bolt Recommendation
    What you'd want is the replacement suspension bolt part # 166079. This is 9/16 inch in diameter like you need and is 3-1/2 inches long too. It comes with matching nut as well.

  • Usable Length of the Wet Bolt 126B2
    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 2-1/2 inches and the overall length is 3 inches. I attached an install video for this bolt for you to check out as well.

  • Wet Bolts for Equa-Flex Cushioned Equalizers
    Yes, we do have the wet equalizer bolts you can use with the Equa-Flex Cushioned Equalizers. You will need # 126B2. I have included a picture showing a typical installation of the bolts being used to secure the springs to an equalizer. Installation of the wet bolts and of the equalizer (in this case) are independent of each other. The Wet bolts are 9/16 inches in diameter so if the brass sleeve in the Equa-Flex makes the hole diameter too small either smaller bolts or no brass sleeves...

  • Recommended Shackle Straps and Bolts for 7K AL-KO Axles on Moritz Dump Trailer With 7-3/4 Equalizer
    For your shackle straps, I recommend the 3-1/2 inch # TRSL350 and for your bolts the Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs - 3" Long # 126B2. These bolts have the zerk fitting to allow you to add grease for better movement and less noise. If you prefer basic bolts, then I recommend # 166081.

  • Do the Equa-Flex Cushioned Equalizers Need to Be Greased Regularly
    I spoke to my contact at Lippert Components Incorporated (LCI) about the Equa-Flex Cushioned Equalizers that you have on your trailer. They informed me that the equalizer does not need to be greased regularly though it would not hurt to spray a bit of white lithium grease like part # L11363 around the bolt sleeves. If you intend to grease them regularly I suggest installing wet bolts like part # 126B2 (see photo).

  • Replacement Trailer Suspension Bolts Options with a Grease Zerk Fitting
    I have attached a link to our selection of suspension bolts that you can filter through. You will just need to make sure that the bolt you use as a replacement has the correct specs. Among the linked bolts is the Redline Wet Equalizer Bolt for Double Eye Springs # 126B2 which has a 9/16" diameter and 3" of usable length. It also comes with the grease zerk fitting that you mentioned.

  • Which Way Should Hole in Wet Equalizer Bolt Face and Can a Locknut be Reused
    On the wet equalizer bolt # 126B2 it does not matter which way the hole faces. Up, down, left, right, anywhere in between, it's all good. A lock nut has mismatched threads a little ways along the thread spiral and either its threads, the bolts threads, or both will get gnarled up so given that these are suspension pieces it would be a good idea to just replace whatever needs to be replaced instead of trying to keep reusing the same lock nut. Really it is situational. The nut could...

  • Recommended Wet Bolts With Screw-In Zerk Grease Fittings
    We offer 2 wet bolts that may work for you because they have screw-in Zerk fittings. The first wet bolt I recommend is part # 34007-187-00. This is a step wet bolt designed to work with 1-3/4 inch double eye leaf springs. The overall length of this bolt is 3-7/16 inches and the usable length is 3 inches. This is a 9/16 inch diameter bolt. These are sold individually so you would need to enter the quantity you need when ordering. The other wet bolt I recommend is part # 126A1. This...

  • Replacement Trailer Equalizer that is 6-1/16 inches in Length
    The closest equalizer we have to what you said you need is the part # TREQ310 that is 6-1/16 inches long and 4 inches tall measured on the hole centers of the equalizer. For bolts you would want the part # 126B2 and then for the shackles part # TRSL350.

  • How Often Should Wet Trailer Equalizer Bolt Get Greased
    Like you said it depends on how much use the trailer gets. If you do not use it very often then it is not working as much and the grease will not break down as quickly. So you will want to grease it at least once a year. If you do use the trailer frequently you might want to check it a few times a year or when you notice the ride quality has changed because the suspension is not moving as freely as it used to.

  • Does The Redline Wet Equalizer Bolt, # 126B2, Come In Different Lengths
    I called the supplier (Redline) and they said the only wet bolt they offer in a 9/16 inch diameter is the Redline Wet Equalizer Bolt, # 126B2. The length of this bolt, not including the head of the bolt or the threads is 2-1/2 inches. The only other wet bolt we offer is the Redline Wet Equalizer Bolt, # 126A1, which is a 3-1/2 inches length with a 3/4 inches diameter.

  • Is it Dangerous to Over Tighten Bolts on Equalizer and Shackle Bolts
    Equalizer bolts, like the Redline Wet Equalizer Bolt with locknut and grease zerk, # 126B2, should be torqued to yield. Equalizer bolts are not given a specific torque rating because they should allow some movement of the equalizer. If they are torqued down too tight, the equalizer will have difficulty moving and that could bind up your trailer's suspension. Simply tighten the bolts down until they are tight, but still allow the equalizer to move. I have provided an installation video...

    You are looking for what we call wet shackle bolts that include a grease zerk fitting for easy lubrication. We offer two such items. Redline part # 126B2 is a 9/16-inch diameter wet bolt that is 3-inches long overall with a usable length of 2-1/2-inches.

  • How to Measure Length of Equalizer on Trailer
    To determine the right equalizer you will want to measure the center to center distance between the holes on the end of the existing equalizer. I have included a link which shows all of the shackle bolts and spring eye bolts we carry. You can then filter the parts by diameter, length, etc.

  • Solution for Needing Replacement Zerk Fitting for Wet Bolt on Trailer Suspension
    I reached out to the manufacturer and the Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs - 3" Long # 126B2 is a pressed in zerk fitting, so it cannot be replaced. This is also true for Dexter bolts as well. There are not threaded zerk fittings available for this bolt size, so it will require purchasing new bolts to have those working zerk fittings.
    view full answer...
  • Wet Suspension Bolt vs a Regular Suspension Bolt
    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 shoot the grease into the center of bolt. Otherwise, with a dry bolt, you will need to find some other way to apply the grease. If given the choice, I would go with the Wet Shackle Bolt, part # 126B2.

  • What Is Bolt Length Measurement On The Redline Wet Equalizer Bolt, # 126B2 And Are Bushings Needed
    On the Redline Wet Equalizer Bolt, # 126B2, the length of 3 inches is not including the head. The overall length is 3-3/8 inches including the head. It is a 9/16 inches diameter bolt. I have the Redline Wet Equalizer Bolt, # 126A1, which has a length of 3-1/2 inches not including the head, but it is a 3/4 inch diameter bolt. Yes, the bushings on the equalizers are needed. They can wear out from excessive movement if the trailer is used more on bumpy roads. We carry the nylon...

  • What Direction Should Wet Equalizer Bolts Face
    It really shouldn't matter what direction the wet bolts part # 126B2 install when used for equalizers or shackle straps. But if Dexter says to install them in the orientation you described then I would recommend you stick with their recommendation. Having the zerk fitting facing out would make accessing them easier.

  • Do Trailer Wet Equalizer Bolts have Press In or Screw In Zerk Fittings
    Without knowing what wet bolts you have it is hard to say for certain, but most likely the zerk fitting of the bolt is pressed in as that is the norm. Since typically the way to fix a zerk fitting that won't take grease is to remove it and then clear it out and reinstall a new one it might just be easier to replace the wet bolts you have to save the trouble.

  • Zerk Fitting Shackle Bolt Recommendation for Trailer Suspension with Longer Span than 2-1/4 inch
    We have the Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs # 126B2 that has a usable width of 3 inches. It also has the zerk fitting like the title indicates and is 9/16 inch in diameter.

  • Comparing Wet and Dry Shackle Bolt Strength Rating
    A wet shackle bolt like the Redline # 126B2, the type that is hollow with a grease zerk fitting for lubrication, is just as strong as the dry (solid) type like # 166081. Neither variety of this part actually carries a weight capacity rating since the trailer weight is distributed across many of them.

  • Upgraded Wet-Bolt Options for a Tandem Axle Trailer
    That is going to depend on how many axles you have, but for a wet bolt that is 3 inches long and has a 9/16 inch diameter that most trailers use you would want the part # 126B2. The price is available at the link below. For a tandem trailer you are most likely going to need 14 of these. The other option we have is the Never Fail suspension upgrade kit # LC281285 that comes with all new bolts, shackles, and self-lubricating bushings. With this you wouldn't have to ever mess with lubing...

  • Can Lock Nuts Be Reused on Trailer Suspension Bolts After Being Removed
    You may be able to reuse the same shackle bolts provided that they are the correct size, are not severely rusted, and are not cracked or otherwise damaged, but not the lock nuts. If you think your bolts might be rusted, cracked, or damaged I would definitely change them out for new ones. When used with lock nuts, the bolt threads could be compromised and I would recommend replacing them. The lock nuts cannot be reused. There are essentially 3 kinds of bolts and 3 kinds of nuts.

  • Could a Wet Bolt with a Zerk Grease Fitting be Used When Installing Trailer Springs

This and all other wet bolts are displayed on the linked page. We also have a 7/16-inch diameter bolt, part # 34007-187-00, which is a stepped bolt that measures 3-7/16-inches long.

  • How Tight Should Wet Equalizer Bolts like # 126B2 When Installed on a Trailer
    When tightening down Wet Equalizer Bolts like # 126B2, our installers in the past have torqued them to about 70 foot pounds. Over tightening can lead to components being damaged so make sure to use a torque wrench that is rated properly. I have included a link to a video that may help as well.

  • Wet Bolt and Shackle Recommendation and Availability
    For wet shackle bolts that are 9/16 inch in diameter you would want the part # 126B2. For replacement shackles you would want the part # 115052. These are the most common sizes used. If you have a need for a different size shackle bolt check out the link I attached to the right to see all the suspension bolts we carry.

  • Troubleshooting Missing Zerk Fittings On Wet Bolts
    I reached out to the manufacturer and the Wet Equalizer Bolt with Locknut and Grease Zerk for Double-Eye Springs - 3" Long # 126B2 is a pressed in zerk fitting, so it cannot be replaced. There are not threaded zerk fittings available for this bolt size, so it will require purchasing new bolts to have those working zerk fittings.

  • Are Grease Fittings Threaded In or Pressed In on Wet Bolt 126B2

  • What Torque Rating Should be Used to Install Trailer Suspension Shackle Bolts
    If you are using 9/16 inch shackle bolts which are the most common you will want 65 to 95 foot pounds of torque. If you are using 1/2 inch then go for 45 to 70 foot pounds. And for 5/8 inch bolts use 100 to 120 foot pounds. All of these components are designed to move so you don't want to over tighten anything.
