Outer, valve spring (White and red paint dabs)
Outer valve spring (white and red paint dabs) for the cylinder head, part 70-8788, also known as E8788.
This is the outer valve spring listed under 70-8788, also found in older parts books as E8788. It shows up in the cylinder head and rocker box figures, where it works alongside the inner spring to hold the valve closed and bring it back after each opening.

The catalog notes this one with white and red paint dabs, which is how Triumph marked spring rate or spec on the coil itself at the factory. If you're pulling a head apart, that paint marking is worth checking against the new part before you reassemble, so you know you're putting the right spring back where it came from.
Our records show this part across cylinder head figures from 1969 into 1974. Beyond that we don't have more detail tying it to a specific model, so give us a call to confirm fitment before you order.
