This part fits 1966-1970 Chevrolet Caprice vehicles.
Upgrade your front suspension with Pirate Jack tubular upper and lower control arms—built for strength, improved handling, and long-term serviceability. Designed as a robust replacement for factory-style control arms, this package delivers a clean, bolt-on fit while helping tighten steering feel, reduce suspension flex, and improve overall front-end response.
These control arms feature heavy-duty tubular steel construction for added strength and rigidity, with a durable gloss black powdercoated finish for corrosion resistance and a clean performance look. Designed to be stronger and more performance-focused than worn factory components, these arms help modernize your classic full-size suspension while preserving a factory-like fit.
Built-in positive caster helps improve steering stability, return-to-center feel, cornering confidence, and overall vehicle control. High-quality greasable Delrin bushings reduce deflection while maintaining smooth suspension articulation, helping the front end feel tighter, sharper, and more predictable on the street. Premium ball joints are included for durability and extended service life, and offset billet cross shafts help improve alignment capability and simplify setup.
These control arms are designed to work with factory springs and shocks, lowering springs, or coilover conversions, making them a flexible foundation for a wide range of street and performance builds. The lower control arms also feature integrated sway bar mounting locations for use with compatible sway bar setups.
Important Installation Note: Lower control arms feature 5/16” welded nuts at the lower shock mount points. These welded nuts must be removed or reamed out to 3/8” for certain coilover hardware installations, including Aldan American coilover t-bar installation. Modified parts are non-returnable.
Note: Sway bar end links are sold separately and are not included.
