The Serpent 401655 Pivot Pin Inserts are made for the 4-X chassis and help give more consistent suspension geometry. They are a straightforward way to reduce unwanted movement and sharpen handling.
By securing pivot points, these inserts let you tune steering and roll behaviour more precisely. They are useful when you need repeatable settings between practice and race runs.
Serpent 401655 inserts are manufactured to resist the stresses of frequent running, maintaining alignment and reducing the chance of premature wear. That adds reliability to race day setups.
