SOHC Model 30/30M 500cc SS Crankcase Cylinder Stud - Set of 4

High Tensile Stainless Steel Cylinder Stud Set for 500cc (and some 350cc) engines (set of 4).

These are CNC manufactured by us to the original dimensions and style and transform the look of your engine (particularly if you originals are rusty or losing their plating). 

Price is for set of 4 studs

These studs are manufactured to the original dimensions (and curved chamfer on each end) as original Norton SOHC studs, to the dimensions of the 500cc models.  However, I have also found some 350cc crankcases share the same dimensions - so please email me at paul.norman@racingvincent.co.uk if you wish to confirm dimensions for your bike before ordering.  

These studs have the standard BSW thread going into Norton cranckases, and the fine thread that fit our SOHC sleeve nuts (Item 0042 or 0043).  They are manufactured from a higher tensile grade of stainless steel than normal, to avoid stretching.

As you can see from the photos, replacing original rusty or pitted engine studs with a set of these stainless steel items will totally transform the look of your engine, as well as preventing rusting in the future.  They are a very popular item.

Note: these studs as standard come with the standard stainless steel bar 'satin' type finish, as shown in the photographs.  In the past I have occasionally linished these studs to give a semi-polished appearance.  If required - we can provide this finish as an optional extra (as of 2023 - expect this linishing to cost @12 per set of 4 studs, and requiest it in the 'comments' section when placing your order.  Turnaround to do this is normally at least 2 weeks - as I have to setup a manual lathe to mount the studs for linishing)

2024 Update:  A new batch of these popular studs are now back in stock.  Price of stainless steel has almost doubled since we last made them 3 years ago, we have only increased our retail cost by a fraction of that amount.
