Triceps in general have a higher fiber-content of fast twitch fibers. You want heavy lifts that offer high degrees of concentric and eccentric stress (dips, CG bench presses), because it maximizes tricep motor recruitment better than cable or DB isolation movements can do.
Here's a fiber make-up schematic for the triceps for those interested:

Generally, 95% of people who are eating enough and growing elsewhere but claim their triceps "can't grow" have one of these problems:
a.) Too much volume
b.) Too little mechanical stretch/stress (generally from relying too much on iso movements)
c.) Combination of "A" and "B"
