DSE Rear Speed Kit 1 (041648DS) - 1973-1987 Chevrolet C10 / GMC C15
Get the stance of your Square Body right without turning the rear suspension into a major fabrication project with the Detroit Speed Rear Speed Kit 1. Designed for 1973-1987 Chevrolet C10 and GMC C15 applications, 041648DS lowers the rear of the truck approximately 3 to 4 inches using Detroit Speed leaf spring front drop hangers and rear drop shackles. The result is a lower, more aggressive profile while retaining a straightforward bolt-on approach that works with the truck's leaf spring rear suspension.
Detroit Speed builds the hangers and shackles from heavy-duty 1/4-inch-thick steel and finishes them in black powdercoat for durability. Both components provide two leaf spring mounting positions spaced 1 inch apart, giving you additional flexibility when dialing in the truck's rear stance. All required mounting hardware is included, making 041648DS a well-engineered foundation for enthusiasts who want to lower their Square Body while keeping installation clean and uncomplicated.
