Effective Turns: Since the coils are closed on each end, they contribute less to the spring rate. The Actual Turns are about 1.5 more than effective turns.

Note that B310 spring is identical to North America B210 spring. The B310 however uses a different upper spring seat.

120Y

120Y is A12-powered B210. It uses similar suspension to B110, unlike the A14-powered B210.

Spring rate: 90.7 lbs/in.
