SPINDLE-FRONT WHEEL 1965-68 TRI SLS BRAKE
Front wheel spindle for 1965-68 Triumphs with SLS front brake, PN 37-1641 (alias W1641).
This is the front wheel spindle listed in the parts book as fitting 1965-68 Triumphs with the single-leading-shoe (SLS) front brake, part number 37-1641, also shown under the earlier W1641 designation. It's the axle that the front wheel and hub spin on, running through the fork ends and holding the whole front wheel assembly in place.

The catalog ties this one specifically to the SLS brake setup, so if your front end has a different brake arrangement, this may not be the correct spindle for your bike. It shows up across the front wheel section of the parts books for the years noted.
If you're rebuilding a front hub or replacing a bent or worn spindle, this is the number to have on hand. Worth confirming your brake type before ordering since the catalog draws a line specifically at SLS brake models.
