THE MID POLISHED
This is the Mid Polished Skateboard Trucks by Independent.

New Independent MiD trucks feature a lower profile hanger for optimal contact point angle on your nose and tail for flip tricks, ledges, and all-around street skating with a recommended wheel size of 53mm and under. The newly designed and first ever Independent inverted kingpin can be used with either a 5.5mm Allen key or standard 9/16" hex wrench. The innovative new Shaft Nut in the baseplate creates a rigid and durable solution to lateral movement found in most inverted kingpin designs and increases adjustability.
