This has been getting some attention lately. thoughts on bolt on vs welded gussets. It’s way cheaper if you don’t know how to weld, but can diy this. i’m skeptical that the spindle will be stronger than welded but i guess this is better than stock if you just need a mild increase in strength.

My first thought was that they looked pretty nice, until I saw how the balljoint is attached. They want you to use a nylock nut instead of the OEM castle nut in order to allow the spindle gusset to fit over the upper ball joint stud. IMO, a nylock nut is not as good as a castle nut with a cotter pin for something critical like a upper ball joint. They rely on a small piece of plastic to prevent the nut from backing off instead of steel wire through the middle of the stud (changing it from a mechanical to friction retention system). So, they may prevent the spindle from getting bent, but would increase (at least slightly) the potential for the UBJ nut to back off and separate, which would cause far more damage to the rest of the rig (or a crash) compared to a bent spindle.

I'd personally get weld-on ones that retain the OEM-style ball joint nut with a cotter pin.

I concur. I was hopeful when first reading about those but they are not a suitable substitute.

Instructions state you should reuse your castle nut if you have a different thread pitch than factory. You've got Ironman UCA's on yours, right? You're probably safe.

other than the removal of the castle nut- does the design seem legit? for the aerospace guys- would a nordlock washer be sufficient to replace castle nut and cotter pin?

We use both...but each has their application. Where it is the only fastener, castle nut and cotter pin is pretty standard.

Yes, I have Ironman UCAs with 555 UBJs in them. And a box of cotter pins as my rig has quite a few on it...

Are you wheeling/desert racing hard enough where you would need the spindle gussets? IMO I think there are many other parts in the rig that would break before you bent a forged steel spindle. And, if a spindle is bent, it should be very easy to find a good used one at a salvage yard, as well as being easy to replace.

I'll eventually put a set of spindle gussets on my rig, but not until after I've reinforced the rear shock mounts and lower control arm hangers, as well as the front LCA cam tabs and frame mount brackets. When I eventually add them, I'll use the weld-on gussets which are around $100. You could always pull the spindles out and take them to a welding shop to have them burned in.
