What Grade Is The Shackle Bolt ABS74FR?  

Your best bet for upgrading the suspension on your trailer with 5,000 lb axles is to change out the springs from 1,750 lb capacity each to at least 2500 lb capacity each. Helper springs would not increase the capacity of your original suspension,…

Both the SMI Stay-IN-Play DUO, part #SM99251 and the Roadmaster InvisiBrake Supplemental Braking System, part #RM-8700 are nice braking systems and will function similarly but I recommend the Duo system. Both systems are a one-time installation. The…

The hub/drum you sent in a picture of is a Lippert 8,000 lb axle hub with an 8 on 6-1/2 inch bolt pattern designed for oil-bath applications. The correct replacement then is the #8-285-10UC3-A.

So after quite a bit of research it seems that the Trostel 300-156-6 seals you mentioned are quite old and have not been around for some time. The best I could find was that they are 3.00" in outer diameter, and I did manage to find a customer…

I do have some great full replacement options for you but the motors are not replaceable on trailer tongue jacks. There might be one or two out there which are but none of the dozens we carry ever have that option. Instead, I recommend the Phoenix…

I did some checking and the hub/drum we offer that will work for you is the part #8-430-5UC3. This uses the same bearings as the 8-415 and will be an exact fit aside from the fact this is a non-ABS setup and the 8-415 came in an ABS setup and non-ABS…

For a standard replacement equalizer for your Dexter 13-122 equalizers you'd want the #TREQE1 or for a cushioned version you'd want the part #K71-653-00 which comes with new shackles and bolts. For a kit that includes new bolts, bushings, and…

I do understand your concern with the potential of a slightly longer thread length on the Shackle Bolt #166081 causing the shackle strap to sit right on the threads. The fact is though that the shackle positioned there as opposed to the unthreaded…

There is no specific torque rating for shackle bolts. You'll want to ensure that the bolts you use are long enough so that when installed you will have at least 2 threads protruding from the nut. Make sure that the bolt you're using has a…

There usually is not a bushing in the upper bolt on the shackle links. When tightening the bolts on the shackle link you will want to get them tight but you do not want to over tighten them. Being tight will not keep the suspension from working…

The standard trailer leaf spring bushing dimension is 1-3/4 inches wide with an inner diameter of 9/16 inch. Easiest solution would be to replace the springs and mounting bolts to allow you to keep the bushing in the new springs but if you wanted to…

The Curved Equalizer for 1-3/4" Double Eye Spring #A2252CB-GALV is not galvanized but it has a powder coat finish which is pretty standard when it comes to trailer suspension parts. The OD of the 9/16" bushing is 11/16" so to replace…
