This spring set is specified for TRAXXAS 1/10 T-Maxx 100mm shock bodies and is supplied as 2 pcs to adjust initial spring rate and rebound response without opening the shock assembly.
From a setup perspective, the 1.5mm wire diameter is a core parameter affecting linearity and load response. Use firmer springs to limit dive and firm up landings, or select softer coils to increase tyre contact on rough terrain. Changes should be validated with short test runs to observe transient behaviour.
Installation follows standard practice for T-Maxx dampers: remove the shock, compress the end cap, exchange the springs and reassemble. For consistent results, pair spring swaps with calibrated oil viscosity and measured preload adjustments, then verify spring seating and full travel clearance during suspension sweep tests.
