Hi Guys - Any idea what model Triumph these are for?
I picked up these fork sliders at a swap meet and found out they are way too long. I was told they are for a pre unit. As you can see in the photo the overall length is 16 1/4" I did a search of pre unit fork sliders and these are several inches longer than any I found info for.

They may be early unit. Not sure of their length but they look similar.

My bet is 1958-59 pte-unit, because of the round mounting boss for the fender, and only one
bottom mount hole, that being for the front stand ('57 and earlier had TWO.)

i believe 1960 and later sliders were shorter.

I'm getting that CRS disease, but here a while back someone posted pics of a unit bike that had longer sliders on it. Most of us didn't know what they could be, but somebody else knew that aftermarket extended sliders were available from somebody back in the old days.

Yeah, these things are super long! From some old posts here, it looks like pre unit sliders are about 12 1/4" from bottom of threads to bottom of slider (axle center) and unit sliders are about an inch shorter. These are about 15 3/4" from bottom of threads to bottom of slider!

What are the casting numbers on them ? You can find them right above the axle lug.

Win, those aren't aftermarket.

My guess is they are modified tubes for a chopper, particularly as they have been chromed.
I have come across this before where two sliders are cut and welded together to make longer sliders.
Have a look inside to see if you can see a weld mark.
Otherwise they could still be aftermarket bits, but using Triumph lugs fixed to new longer tubes.
