These are exactly what I needed after discovering through no fault of etrailer that I ordered the incorrect suspension upgrade wetbolt kit. There are two for triple axle. One is for standard CRE3000 suspensions and one is for CorrecTrak versions. The difference in the two kits is that 6 of the bolts responsible for frame mounting the suspension components are 3 3/8" long instead of 2 7/8" long to accomodate the thicker correct track allignment plates. These were delivered promptly and fit perfectly. Torque, grease and go.

I bought 2 bolts for $40 dollars and there were no nuts with them. They are useless without the nuts. For twenty dollars a bolt they should have sent a stinking nut with it. But no, I have to drive 24 miles to get a nut, that should have been with the bolt. Not a good way to do business. It’s little details like this that lose you customers.

I know the picture did not show a nut, but I was expecting a nut to come with the bolt. What good is a new bolt without a new nut to go with it???

In the original wet bolt kit, I had 2 lock nuts that did not lock and I lost a bolt. This was on my first trip. They were all properly torqued to specs. I think trailer should have replaced my
Missing wet bolt and nut. But I was required to purchase new bolt and nut, which is not cheap. I have received my new bolt and nut and will be installing today. I am hoping they do not come off as well. Wish me luck.

You just need to know that you need to get the right hardware to use the bolt. The Morryde hardware is 3/8-16, this bolt is 1/2-20 which is better IMHO.

Quality and service from Etrailer is the best.
The shipping (usps) is no good. I know it's not etrailer fault. From now on I will only ship FedEx.

See what our Experts say about this MORryde Trailer Suspension Parts
- Is Correct Track Trailer Alignment and Lift Kit Compatible With MORryde Suspension Upgrade KitIf you install the Correct Track Trailer Alignment and Lift Kit # RR23QX it will require longer bolts but MORryde makes a kit specifically for this. To find the right MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track you will need the center to center bolt hole measurement from your current shackle straps. If you have 2-1/4" shackles you need the MORryde Suspension Upgrade Kit for Tandem Axle Trailers w Correct Track # MR58ZR. If you have 3-1/8" you need the # MR98ZR...
view full answer... - Does the MORryde Replacement Wet Shoulder Bolt Come W/ a NutHey Alen, no, the Replacement Wet Shoulder Bolt # MR52HR does not come with a nut. You'd need to order the Replacement Grade 5 Flange Lock Nut for MORryde Suspension Upgrade Kits # MR85DR separately. Let me know if there is anything else I can do for you!
view full answer... - Does The Replacement Wet Shoulder Bolt MR52HR Come With The Lock Nut? Hey Jeff, thanks for reaching out. The Replacement Wet Shoulder Bolt # MR52HR comes with just the bolt. The nuts are sold separately but we do have those available. For that bolt you'll need the following: - Replacement Grade 5 Flange Lock Nut for MORryde Suspension Upgrade Kits - 1/2"-20 - Qty 1 # MR85DR What kind of trailer is this for? What happened to the original bolts that they needed to be replaced?

Here's the replacement wet bolt, bushing and lock nut for the MORryde ALLTREK4000 equalizer # MR89DR: Replacement wet bolt qty 1 # MR52HR Bronze bushing qty 1 # D014-077-00 Replacement Grade 5 Flange Lock Nut qty 1 # MR85DR Do you mostly tow on highways, through the mountains, or on rough campground roads?
view full answer... - Are Bushings And Install Hardware Included With MORryde CRE3000 Equalizers?Hi Terry! The MORryde Rubber Equalizers for Tandem Axle Trailers - 33" Wheelbase - 8K # MR87ZR do include the copper/brass bushings, but the wet bolts are sold separately. For that, you would want the Wet Shoulder Bolt - MORryde Suspension Upgrade Kits - 9/16" x 3-3/8" - Qty 1 # MR52HR (and the Grade 5 Flange Lock Nut - 1/2"-20 - Qty 1 # MR85DR). Those wet bolts are included in the MORryde shackle kits, however. If you are interested in those, I have the two we carry listed below with...

It measures 9/16" x 3-3/8". They're sold as part of a kit with the MORryde Suspension Upgrade Kit for Tandem Axle Trailers item # MR76ZR. What kind of trailer do you have? You can add this information and any other questions you have in the box that says Reply to Jerred H.
view full answer... - X-Factor and Wet Bolt Kit for 2022 Montana High Country 331RLHey Greg, welcome back! The correct MORryde X-Factor for your 2022 Montana High Country 331RL that has the CRE300 equalizers is the # MR33WR. The best solution is to run three of these. One for the front, center and rear hanger. If you are only going to do one you should do the center. If you are only going to do two you would want to do the front and the back but all three is your best solution. The correct wet bolts you would need then would be the part # MR52HR. This is correct for...
view full answer... - Replacement Wet Bolts For A MORryde CRE3000 Suspension Hey John, Yes, you'll just need to measure the length of the bolt to determine the correct replacement. MORryde offers a 2-15/16" long bolt # MR92HR as well as a 3-3/8" long bolt # MR52HR if you have a Correct Track system.
view full answer... - Replacement Bolt For MORryde CRE3000 And X-Factor CrossmemberWelcome back, Tom! The MORryde Replacement Wet Shoulder Bolt - 9/16" x 3-3/8" - Qty 1 # MR52HR will definitely work for you, but are you measuring just the threaded portion or the actual shank of the bolt? I ask as the threaded portion of the # MR52HR bolt will measure 1/2", though the rest of the bolt shank is 9/16" (see included image). This is fairly common with these bolts and the top hole on the MORryde CRE3000 Equalizers # MR27ZR is 9/16". I think a 1/2" bolt would have caused issues...
view full answer... - Recommended Longer Wet Bolts for a Correct Track Trailer Alignment and Lift KitHey Rick, welcome back. If you don't want to use the bolts included with the Correct Track Trailer Alignment and Lift Kit item # RR23QX or item # RR55QX, you can replace them with the 3-3/8" Replacement Wet Shoulder Bolt item # MR52HR. Using two of these will replace the bolts that hold your equalizers onto the brackets attached to the spring hangers. It's highly recommended to replace you suspension bolts when you take your leaf springs and equalizer apart. MORryde makes a couple of...
view full answer... - MORryde Wet Shoulder Bolt Not Taking GreaseHi Tony; it sounds like you have some dirt/debris lodged in there which is preventing the grease from going through. Since you already replaced the fitting I don't think cleaning it further will work so I would replace the whole bolt with the Replacement Wet Shoulder Bolt # MR92HR (9/16" x 2-15/16") or # MR52HR (9/16" x 3-3/8").
view full answer... - Flange Nut to Fit with MORryde Shoulder Bolts for Trailer SuspensionHey Michael, thanks for reaching out! The Shoulder Bolts # MR92HR and # MR52HR will fit with the Replacement Flange Nut # MR85DR . We don't have a specific one from MORryde that works, but they are both compatible with this one so it can be used instead! Is there anything else you're needing to upgrade or replace?
view full answer... - Replacement Wet Bolt for MORryde Suspension Upgrade KitHey Steven; you do not need to buy a complete kit. If you need a 2-15/16" long replacement bolt it is the # MR92HR and for a 3-3/8" # MR52HR. If you need a replacement bushing as well you can use the # LC32SV. Might be a good idea to pick up a few spares just in case.
view full answer... - Can Bushings and Bolts of Lippert Road Armor be Replaced with Wet Bolts and Bronze BushingsHey Evert, what you would want is: - Wet Bolt # MR52HR (Comes with 1) - Bronze Bushings Kit # K71-291-00 (Comes with 4) To replace the bushings and bolts of your Road Armor setup.
view full answer... - Availability of Replacement Wet Bolt and Bushings for MORryde HD Shackle KitHey Scott, for a replacement wet bolt for your MORryde shackle kit you would want the part # MR52HR. Then for bushings you would want the part # K71-291-00 for a set of 4.
view full answer... - What Bronze Bushings Go With The 4-Leaf Double-Eye Spring DX23CRHello Reuben, thanks for reaching out. We do have a bronze bushing that will work with the # DX23CR Leaf Spring. For that you will need the following: - Bronze Bushing - 9/16" Inner Diameter, 11/16" Outer Diameter - 1-3/4" Long - Qty 1 # D014-077-00 These must be used with wet bolts, since that is how they are lubricated. A wet bolt like part # MR52HR would work great. These are typically sold as a full suspension kit that comes with shackles, bronze bushings and wet bolts. For example,...

- Are the Wet Bolts in the MORryde Suspension Upgrade Kit a One Time UseNo, that is not completely true. The wet bolts can be re-used as long as they are not rusted, cracked or damaged in any other way, to include the splines or threads being damaged. The main thing that you'd want to replace is the lock-nut which can be sourced locally. The Replacement Wet Shoulder Bolt # MR52HR (for attaching the springs to your equalizers) is the correct bolt for the MORryde Suspension Upgrade Kit # MR46ZR you have. There is also another wet bolt used which is the Replacement...
view full answer... - Replacement Wet Bolts For MORryde X-Factor CrossmemberThe MORryde X-Factor Crossmember uses 2 of the Wet Shoulder Bolts # MR52HR. I recommend using the LubriMatic LMX Industrial Strength Grease # L11390 with these bolts. This grease is formulated to work well in both hot and cold climates. It is also highly water insoluble so it will not wash away easily if you drive in wet conditions. The Grease Gun # L30416 has an 18" flexible hose to make it easier to reach the wet bolts.
view full answer... - Comparing MORryde and Lippert Wet Shoulder Bolts # MR52HR and # LC126197The MORryde Wet Shoulder Bolt # MR52HR and Lippert Equa-Flex Wet Shoulder Bolt # LC126197 are identical in in size. The only difference I can see is the one comes from MORryde while the other comes from Lippert. Both have a length under head of 3-3/8", bolt dimension of 9/16", thread length of 9/16", usable length of 2-13/16", tread size of 7/16"-20 fine and a bolt head diameter of 13/16".

view full answer... - Correct Replacement Wet Bot for Grand Design Trailer with MORryde CRE300 EqualizersThere are two different size shackle bolts that come with the MORryde Suspension Upgrade Kit for Triple Axle Trailers, part # MR92HR which is 2-15/16" long or part # MR52HR which is 3-3/8" long. The longer bolts are used on models with the Correct Track system. The correct size locknut you need is 7/16"-20 which you can obtain locally. Unfortunately, we don't offer the locknuts or shackle links separately.

The item # e44SR you referenced is the same size but has a 5,000 lbs capacity. You can use a higher capacity leaf spring, however it won't increase the capacity of your trailer as the axle is still rated for that maximum capacity of 4,400 lbs. I would go with the 4-Leaf Double-Eye Spring for 3,500-lb Trailer Axles item # DX23CR. It'll be softer but expect it to be stiffer than the 2,200 lbs springs you're currently...
