The ARA330837 is Arrma's pink shock spring rated at C=0.359N/mm, supplied as a pair and listed by Arrma for the 1/10 2WD Freedom Flyer, Gorgon and Quake. Approximately 2.05 lb/in in imperial terms, for anyone working from the American tuning charts.

The spring carries the truck's weight and sets how far the suspension travels under a given load; the shock oil controls how fast that travel happens. The two work together, and changing one without understanding the other is where most suspension tuning goes wrong. A spring that has taken a set — gone shorter and softer after a season of hard landings — will sit the truck lower at rest and bottom out earlier, and because springs sag unevenly, one tired spring on a corner will pull the chassis off level.

Arrma produces this rate in several colours. The colour identifies the part number, not the rate — a pink ARA330837, an orange ARA330836 and a green ARA330835 all spring identically. Choose on appearance, or on matching what is already fitted.
