The Speedmaster PCE179.1017 tubular front upper and lower control arms are engineered specifically for 1955–1957 Chevrolet Bel Air Tri5 vehicles, delivering a direct-fit upgrade over factory stamped-steel arms. The tubular construction reduces unsprung weight while improving front suspension geometry for a more responsive, controlled ride whether you're cruising the strip or hitting the track.
Designed as a complete front control arm kit covering both upper and lower positions, this Speedmaster set simplifies installation and ensures consistent geometry across both arms. A great choice for classic Tri5 Chevy builds looking to modernize handling performance without sacrificing the integrity of the original suspension layout.
