Koswork Rear 61mm Set AE (1.8/1.9/2.0/2.3 lb/in, 12/13mm) RC Shock Spring Set - KOS04851RSET

The Koswork KOS04851RSET Rear Shock Spring Set is a multi-rate spring kit designed for Associated Electrics RC cars running 12mm or 13mm rear shocks. The set covers four spring rates — 1.8, 1.9, 2.0, and 2.3 lb/in — each at 61mm in length, giving you a practical range of tuning options without needing to order individual springs separately. If you're dialling in rear suspension feel on an Associated Electrics buggy or truck, this set lets you work through rate changes at the track rather than waiting on parts orders.
