67-72 Coil Over Chassis - #Chassis6772-Coil

The GSI 1967-1972 C10 Coilover Chassis is designed for builders who want a sportier, performance-driven setup with a significantly lowered stance, modern handling, and increased structural rigidity. This Ridetech coilover suspension is ideal for autocross, pro-touring, and high-end street/show builds.

While it does not lay frame, this chassis sits aggressively low with predictable handling, a strong road feel, and consistent performance under hard driving. The rear suspension and notch system support aggressive lowering and wide wheel fitments up to 24” x 15” while maintaining suspension travel and drivability, making it ideal for tight show or track-focused trucks.


Performance & Low Stance

Each chassis is hand-fabricated and fully welded by professional fabricators using MIG and TIG welding methods. OEM frames are laser scanned to ensure proper geometry, accurate suspension pickup points, and consistent fitment across builds. Main chassis rails and structural components are fabricated from ASTM A1011 hot-rolled steel, selected for its strength, consistency, and weld quality.

Optimized suspension geometry minimizes camber change through suspension travel, reduces bump steer, and maintains stable alignment at ride height, which is critical for competitive driving and spirited street use.

Integrated GSI Lower Control Arm Alignment Cams and the GSI Tie Rod Adapter Kit allow for straightforward alignment adjustments while maintaining correct steering geometry.


A Serious Foundation

Primary chassis and suspension components arrive installed. Some components and optional add-ons may ship boxed separately on the pallet, depending on configuration. The chassis provides a strong, accurate foundation ready to accept a body, drivetrain, wheels, plumbing, and finishing components—without fabrication guesswork.
