My chain slider was worn through and I wanted to see if I could fix it instead of buying a new one, which I could and it worked out well.
I blame it wearing out on my slightly lowered suspension and the srt chain on a 13 tooth front sprocket, the srt chain is larger height wise than normal cutting the clearance between the chain and slider down.
If you don't want to replace the chain slider when it wears out you can patch a new piece onto the front of it where it wears.
I used super hard uhmw white plastic that I had lying around but you could also use a hockey puck its just big enough plus would be black so it would be harder for someone to notice the repair.
I cut out the worn section so I'd have a flat square place to put the patch, its attached by 2 screws from the side, I drilled tiny pilot holes for them and they're up as high as possible so the chain wont dig into them as it wears. I cut it with a re sip saw and ground it down with a 4 inch angle grinder to get it to match the shape of the original slider, its not a perfect match but close enough to fit well.
This took me 30 minutes tops to do, it wasn't hard at all and this stuff is way harder then the stock material so it will last longer.
Heres some pics.
