Challenger b40050 Billet Cable Sheave / Pulley for 4-Post Lifts
This is an upgraded billet cable sheave pulley for Challenger 4-post lifts. Unlike the original cast metal pulley and thin bushing these lifts came equipped with, this unit features solid billet construction paired with a durable bronze center bushing for extended service life. Found under the runway on many Challenger 4-post lifts in stacks of 2, 4, and singles, as well as used in all 4 cross-rail beams in each corner.
