Ace Controls International's new SC300 and SC650 'Heavyweight II' series
of have an effective weight range some
ten times greater than that of its existing Magnum series, and an energy
capacity up by nearly 200%. Ace says it has achieved this by combining
the piston and inner tube into a single component that acts as both a
pressure-creating and pressure-controlling device.
Shock absorber performance within a comparable body shell is directly
related to piston area; the new units have a piston area that is some
250% greater than previous models. The SC300 handles effective weights
from 11 to 181kg, with an energy capacity of 73Nm/cycle, while the SC650
handles effective weights from 23 to 1,089kg with an energy capacity of
210Nm/cycle.
