This line has been developed for heavy duty specifications, motor change or CNG vehicles.
We count with two types of heavy springs, the Reinforced (R) and Heavy Duty (TP).
The Reinforced (R), compared to the AG Comfort line, is produced with the same steel diameter and the same number of coils but with a higher height and bigger coils, making the spring harder. Reinforced is recommended for CNG tubes not heavier than 50/60 kg.
The Heavy Duty (TP) counts with bigger coils and bigger steel diameter to increase its hardness. This spring is recommended for heavier equipments, dual tubes or commercial vehicles (such as taxis, vans, etc.)
AG Heavy line counts with a one-year warranty and has the widest range of aftermarket springs.
