Choppin' Block Front Coilover Performance Kit - 73-87 C10

The Performance Series front kit provides a mid-level drop with uncompromised performance and handling. An athletic stance and aggressive suspension geometry will transform your truck into the performer you deserve. The modular system replaces the factory crossmember and control arms with a new crossmember and tubular control arms with adjustable alignment cams. The steering is converted to a Mustang II rack and pinion with an adjustable flipped tie rod kit which requires no clearance modifications to the frame. The revised geometry offers world class handling and steering by increasing caster, improving camber curves and eliminating bump steer. Installation is a breeze as each kit is a bolt-on assembly with no welding required. We offer multiple engine mount options for effortless integration of your chosen powertrain and is compatible with all major coil-over manufacturers.
