New Camshaft standard profile TR2-TR4 with timing 15-55 55-15 degrees. New blanks of sufficiently high quality are currently available making this our preferred option alternatively an exchange camshaft 301466EX can be supplied. See below

These camshafts are only supplied to special order as the TR4A camshaft 307036 is preferred for all TR's 2-4A and Italia as it has superior valve timing. Install this camshaft to the original workshop manual bearing in mind any markings for lining up the camshaft on the chain sprockets and camshaft will now be irrelevant.
We often have good second hand camshafts available supplied under part numbers 301466SH and 307036SH which are listed below along with our range of performance camshafts.
When installing a camshaft, to avoid excessive and premature lobe wear it is important to use valve springs which provide the correct seat pressure. We recommend standard spring pressure, certainly no more unless you are consistently revving to 7000RPM!
Only just enough spring pressure is required to ensure the valve stays closed when it should be, without valve bounce. Any more is too much and will put unnecessary load on the camshaft lobes, possibly resulting in premature lobe failure.
When choosing valve springs it is also important to check that the extra lift of our performance camshafts does not result in coil binding on full lift. This should be checked (even with standard camshafts) with the head and the valve gear assembled and valve clearance correctly set. It should be possible to leaver down the valve by an extra 3mm for safety with the valve at full lift.
Please see the appropriate catalogue section for a range of suitable springs HERE.

New camshaft followers (tappets) should always be fitted with a new, exchange or second hand camshaft as the under face of the follower develops a wear pattern particular to the lobe it has been running with. If a used follower is fitted with a lobe it has not operated with before (even another lobe on the same camshaft) then rapid wear will ensue; order 8 off RTR1024 followers.

Camshaft installation paste should be used to protect the lobes when the engine is started for the first time. These products can be found HERE and listed below
