The Dampers are manufactured from billet aluminium, anodized to protect from the elements, and constructed without the use of welding. They also feature a new ultra progressive valve system that can be adjusted to suit different spring rates.

Pro-tech 500 series is made from 6262 spec. aluminium with adjustable spring seat platform for 2.25” i.d spring, with a single adjustable knob which adjusts bump and rebound simultaneously. Backed by a 3 year warranty against defective manufacture.

Features

1.The lower base and eye is designed to hold the threaded body on the outside giving more internal clearance and movement as well as extra strength.

2.Extra machining the lower eye mounts into the solid part of the base gives vital clearance and weight advantage as mounting bracket fouling is eliminated.

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

4.The control knob has only 13 click settings with a total movement of 300 degrees (less than one turn) see note 8 for resetting knob for softer and harder range.

5.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.

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

7.Wisbech Engineering units are fitted with a heavy duty 5/8” shaft for extra strength and durability.

8.After assembly, the unit is tested with a very latest computer controlled damping dynamometer to establish damper conditions and calibrations. All units are set with an adjustment range to suit 95 per cent of most applications. However in the event of needing a lower range of damping this can be achieved as follows on or off the car:-
a)Turn control knob to off position (anit-clockwise) then turn six clicks clockwise.
b)Holding knob firmly against shock absorber, unscrew 4mm grubscrew in the side of knob by one half turn.
c)Still holding knob firmly against the body turn control screw in centre of knob with screwdriver half a turn clockwise to increase damping range or half a turn anit-clockwise to decrease damping range.
d)Lock up 4mm screw
e)Holding the knob firmly against the body at all times 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 the knob to correct.
