Both of the hitch pin holes on the Bulletproof Hitch # ED20SHACKLE are 5/8". This is basically universal for all of the tow shackles we carry. We do not carry a tow shackle that will accept a 3/4" hitch pin. view full answer...
I went out to the warehouse with the digital caliper # PTW80157 and found that the shackle of the Roadmaster Quick Disconnect Padlocks # RM-308 measures about 0.23" which is close enough to 1/4" that it is classified as a 1/4" shackle (technically it's about 15/64").
If you were using 9/32" shackles and they barely fit then that might be what the issue is. I would do some double checking with your setup and make sure that everything is seated properly and nothing is forced into place. view full answer...
The Buyers Products Drop Forged Heavy-Duty Towing Shackle part # 337B0681 is 6" wide by 5" tall. The lower mounting holes are 4 3/8" center on center and the top hole to both lower holes is 3 5/8".
I have linked a diagram on this to show it exactly and a video giving more details on the shackle portion. Check it out. view full answer...

From the center of the hitch pin hole to the center of the shackle bolt hole on the Curt Tow Strap Loop for 2" Hitches # C45832 is going to be about 4-1/2" (see attached photo). view full answer...
The Rampage Front Recovery Bumper # RA88510 accepts a 7/8 inch diameter pin through the shackle mount holes. The shackle mounts are approximately 1 inch wide. The hole diameter is actually 0.92 inches which is closer to 15/16 inches than it is 7/8 inches. The Roadmaster adapter # RM-035-1 will fit around the D-ring mounts but the pin options for the hole are either 7/8 or 1 inch in diameter. So it isn't an exact fit but the 7/8 inch pin would be the better option. view full answer...
The Tow Ready loop, part # TR63046 measures 7-1/16 inches from hitch pin hole to center of tow loop.
The Bestop Loop measures about 6-5/16 inches from the hitch pin hole to center of tow loop. The version I have in front of me also uses a red shackle bolt. view full answer...
The space between the ears of tow bar adapter # RM-035-1 is slightly more than 1 inch to fit D-Ring tabs that are 1 inch thick. The hole for the pin is 1 inch in diameter. The pin itself is 7/8 inches in diameter. For D-ring tab holes that are 1 inch you would use the included sleeve with the pin. D-ring tab holes that are 7/8 inches you would just use the pin without the sleeve. view full answer...
Usually leaf spring hangers have one hole on each side to allow the shackle bolt to run through the eye in the spring and then be secured to the hanger, as on a part like # E4139. But if your hangers have multiple holes to allow a choice of trailer height you can certainly use the lower set of holes to lift the trailer relative to the axle.
If you refer to the linked diagram you'll see the recommended minimum clearances for 5th wheel towing. 5-1/4-inches of clearance at the bed rails is... view full answer...
We do recommend certain minimum clearance distances between a 5th wheel trailer and the truck's bedrails, tailgate and rear bumper. The diagram I have linked for you at right shows these recommended minimums for safe 5th wheel towing.
Between the top of the bed rails and the bottom of the trailer overhang we suggest no less than 5-inches of vertical clearance; between the truck's tailgate and the front of the trailer no less than 4-inches when making turns; and between the rear edge of... view full answer...
Trailer leaf spring # e34SR, when a pair are used and loaded to the maximum of 6,000 pounds, would not completely flatten out just sitting. But when going over bumps it will bottom out at the max load. That would be 3 inches of deflection but you will want to shoot for a little more clearance to be on the safe side since it sounds like you might be doing some heavy duty towing!
Another option is to use an axle-less system such as # TASR7KS01 which has built-in suspension. This system is... view full answer...
A standard beam axle made for a leaf spring suspension will vary only slightly more in its actual weight, depending on its carrying capacity, than two Timbren axle-less systems of different capacities. This is because as weight ratings increase a beam axle tends to have a larger diameter and more steel, which makes it heavier. With Timbren kits there will be a bit less of a weight difference.
For instance, Timbren 3500-lb-rated kit # ASR35HDS02 has a shipping weight of 152-lbs, while their... view full answer...
