Fully adjustable billet alloy rear shock

 Fully adjustable billet rear shock
Considered to be one of the best if not the best rear shock available
The spring is duel rated at 275/350 lb loading with further adjustment by means of a 'C' spanner .It also has the function to alter the damping rate of the spring from soft to hard by means of a 13 point thumb wheel adjustment at the base .
The shock spring can also be removed by hand for painting or chroming if you desire.
This shock is British made  and as such all parts are available in the event of a malfunction though very unlikely.

Design Features

·  New internal sealing system is designed to eliminate high pressure bleeding so all movement of oil in bump and rebound is consistently controlled through the piston and base valve.

  The top and bottom eyes cnc machined with a spherical surface for looks and strength.

·  The control knob has only 13 click settings with a total movement of 300 degrees (less than one turn).

·  Pro-tech has eliminated the coil spring in the control, which most manufacturers still use; coil springs in constant use do not maintain height and will take a set and create inconsistent damping.

·  Pro-tech high performance disc spring system, infinitely variable spring characteristics can be achieved by the arrangement of disc springs into stacked column and by adjusting the control knob to change the force/deflection maintaining constant damping.

·  After assembly the unit is tested with the very latest computer controlled damping dynamometer to establish damper conditions and calibrations. All units are set with an adjustment range to suit 95% of most applications. However in the event of needing a lower range of damping or a higher range of damping this can be achieved as follows on or off your lambretta

a.        Turn control knob to off position (Anti-Clockwise) then turn six clicks clockwise

b.        Holding knob firmly against shock absorber unscrew 4 m/m grub screw in the side of knob by one half turn

c.        Still holding knob firmly against body turn control screw in centre of knob with screwdriver half a turn clockwise to increase damping range or half a turn anti-clockwise to decrease damping range

d.        Lock-up 4 m/m grub screw

e.        Holding the knob firmly against body at all times this prevents the spring and ball bearing coming out of it's location - if this happens you will lose your "Click" action which means removal of knob to correct
