  • Ordered flishrc cobra. Communication was great. Ordered larger batteries but they were the wrong size. Olly shipped the right batteries and gave a refund for the difference I paid. Couldn't ask for more. Thanks for the help with the order.

About this product

Precision Coil Springs for TRAXXAS X-Maxx

The TXMSP28 spring set is engineered as a direct replacement for TRAXXAS 1/8 X-Maxx platforms. It supplies 2.8mm wire-diameter coil springs sized to work with standard dampers or compatible optional shock units, enabling quick evaluation of increased spring rates without shock body modification.

Standard service procedures apply for installation: remove the shock cap and spring retainer, fit the new spring, then reseal the shock. Routine hex tools and shock service implements are sufficient. The set is intended for on-vehicle swaps so tuners can compare dynamic responses across multiple setups.

From an engineering viewpoint, the increased 2.8mm wire diameter raises the spring constant relative to softer coils, shifting static ride height and altering the interaction between spring force and damper damping. Achieve target behaviour by pairing the springs with suitable shock oil, preload settings, and revised mounting geometry.

This item is compatible with

  • TRAXXAS XMAXX

What dimensional checks should I perform before fitting?

Verify spring free length and seat compatibility with your X-Maxx shock assembly, and confirm clearances at full travel to avoid coil contact with other components.

How does wire diameter relate to spring rate?

Wire diameter is a primary factor in spring stiffness; increasing diameter increases spring rate nonlinearly, so the 2.8mm coils provide a noticeably firmer rate compared with smaller wire gauges.

Recommended setup steps after installing these springs?

After fitment, set static ride height with preload collars, select shock oil to control compression and rebound, then test and adjust mounting positions to balance roll and pitch response. Write Product Review Please sign in your account before you can write any review.
