Traxxas was one of the early pioneers of the ST class.
LS and LS-IIEdit
Based off of the Eagle Line, these trucks were practically the same. The LS was single decked, the LS-II was double. Both had graphite chassis, and had zero-flex marketed. The LS had a Ford F-150 ST shell, and the LS-II had an ST shell loosely based off of the Chevrolet Silverado.
Based off of the TRX-3 from the TRX Buggy Line, this model had a longer upper deck, larger dished wheels, longer A-Arms, and a ST body, directly off of the LS-II.
