Koswork Front 44mm Set 3.6–5.1 lb/in 12/13mm AE RC Shock Spring Set - KOS04850FSET

The Koswork KOS04850FSET Front Shock Spring Set is a tuning-focused RC shock spring kit designed for 12mm and 13mm front shocks on Associated Electrics compatible 1/10 scale vehicles. The set covers five spring rates — 3.6, 3.9, 4.3, 4.6, and 5.1 lb/in — giving you a practical range to dial in suspension feel across different track surfaces and driving conditions. Each spring measures 44mm in length, making these a direct fit for front shock assemblies on compatible AE cars without any modification.
