RATIO® patented gear technology
RATIO® - Calibrated Machine Heads incorporate different string gauges into the tuning equation.
From Low E to High E 39:1, 24:1, 20:1, 35:1, 20:1, 12:1.
We balanced the gear ratios to each string simplifying the tuning process.
With RATIO®, a half-turn is a semi-tone!
Every string reacts the same to any tuning adjustment. Predictable, precise tuning, on every string.
The PRL-8341 is a left-handed set of Locking RATIO® Calibrated Machine Heads for electric guitars that use 3 x 3 tuners, such as Gibson style and PRS style guitars.

A bit expensive compared to competitors, but absolutely worth the extra money.
The only downside for me, was that the connection plates didn't match my original Kluson Waffle back.
