Shocks and strUts should be removed/installed according to guidelines in the car's factory manual except for torque settings for the piston rod top nut.

CAUTION - The D-Spec adjustable shock/strut uses a hollow piston rod for the adjusting rod.

As a result impact wrenches should never be used on the piston rod top nut. Torque settings for the D-Spcc shock and strut piston rod top nut are as follows:

Shock absorber (12mm piston rod) 25-321b1ft

Struts (4mm piston rod) 38-49Iblft.

Using an impact wrench or too much torque can break the top of the piston rod.

ADJUSTMENT - The D-Spec units come from the factory at or near the Firm or Hard Setting. DOUble-check the settings front and rear by turning the adjuster clockwise until it is snug. Then turn the adjuster 5 complete revolutions in a counter clockwise direction. This is a good starting point.

Caution - Because of the wide adjustment range, experimenting with various adjustments should only be done after reading the D-spec user manual. The manual explains how various suspension components work together and the possible effects of various D-Spec adjustments.

INSTALLERS - Please install protection caps to keep dirt and debris our of the adjuster hole.

Also please be certain that the D-Spec users manual is given to the vehicle owner and driver with the caution to read the manual.
