Liner-S is a Performance Tip released as part of the Burst System as well as the SlingShock System. It debuted in western countries with the release of the Gold-X Betromoth B4 & Galaxy Zeutron Z4 Dual Pack.
Liner-S, as its name implies, is a SlingShock Performance Tip based off of Liner. However, unlike the original Liner, Liner-S is significantly taller, and features two gaps on either side of the cylinder base, which is meant for the activation of its “SlingShock Mode”. Aside from this, Liner-S keeps the same “Stabilization” gimmick from its original counterpart; which is through the use of its vertically free-spinning wheel. As a part of the SlingShock System, Liner-S can be manually altered to switch between “Battle Ring Mode” and “SlingShock Mode”; in this case, by twisting the base clockwise, pulling it downwards, and twisting the base clockwise again, and vice-versa.
