Rear Frame Rail Kit - 68-76 Nova

The Rear Frame Rail Kit for 1968–1976 Chevrolet Nova by Competition Engineering is an essential structural reinforcement for Nova owners pursuing serious frame restoration, chassis stiffening, or performance modifications. This kit addresses the inherent flex and deflection in original Nova rear frame rails—a known weakness when upgrading suspension geometry, increasing cornering loads, or installing modern braking and suspension components.

Whether you're executing a full frame-off restoration, building a street-strip cruiser, or reinforcing an aging chassis for autocross duty, this rear frame rail kit restores structural integrity and provides a solid foundation for suspension tuning. Competition Engineering's rear frame rail kit is engineered to replace or reinforce the original stamped steel rails, which can crack, separate at welds, or exhibit excessive compliance under load. The kit measures 65 inches in overall length and is designed to bolt and weld into position, providing continuous lateral support across the rear suspension mounting points and rear axle attachment surfaces.

The robust design resists bending and torsional stress during hard acceleration, braking, and cornering—critical when running performance tires, lowered suspension, or drag racing setups. Installation involves careful alignment with existing frame structure and precision welding to ensure frame squareness and axle centerline consistency. This rear frame rail kit is ideal for serious Nova enthusiasts looking to enhance their vehicle's performance and durability.
