In the high-stakes world of chassis alignment, your caster readings are only as reliable as the vial in your gauge. Over time, exposure to UV rays, extreme trailer temperatures, or accidental drops can cloud or damage the original vial. The Longacre 52-78243 Replacement Caster Vial is the genuine factory-spec component required to restore your gauge to professional-grade accuracy.
This specific vial features a wide -4° to +12° range, making it the standard for modern racing front ends that require significant positive caster for high-speed stability. Designed as a "No Lines" version, it provides a clean, unobstructed view of the bubble, intended for use with Longacre gauges where the degree increments are etched directly onto the aluminum gauge body.
