S1 LOWER ARMSOVERVIEW

VIEWED FROM FRONT LEFT OF VEHICLE

THE LOWER ARMS ARE MIRROR COPIES (NOT IDENTICAL COPIES) ON EITHER SIDE OF THE VEHICLE

REMOVE ALL BUSHES DURING WELDING TO AVOID HEAT DAMAGE

21

SOME VEHICLES REQUIRE SHOCK-ABSORBERMOUNTS ON THE LOWER SUSPENSION ARMS,WHILE OTHER VEHICLES MOUNT THE SHOCK-ABSORBERS TO THE SUSPENSION UPRIGHTS.

BOTH TYPES OF ARMS USE THE SAME CONSTRUCTIONAND THE SHOCK-ABSORBER MOUNTS CAN BE ADDED

IF REQUIRED.

(VIEWED FROM BELOW)

THE ARMS CAN BE WELDEDON A FLAT SURFACE.

TACK WELD ONE SIDE OF THE ARM BEFOREFLIPPING THE ARM AND WELDING THE

OTHER SIDE. FULLY WELDING ONE SIDEBEFORE FLIPPING CAN LEAD TO SEVERE

HEAT DISTORTION.

ONCE THE 5 TUBES AND 1 GUSSET PLATEARE WELDED TOGETHER, THE ARM IS READY

FOR USE ON VEHICLES WHICH DO NOTREQUIRE A SHOCK-ABSORBER MOUNT

ON THE LOWER SUSPENSION ARM.

VEHICLES WHICH REQUIRE AN ARM SHOCKMOUNT MUST BE FITTED WITH THE SHOCK

MOUNT SHOWN OVERLEAF.
