Jacobs Ladder Adjustable 14in (Large)

The Allstar Performance Jacobs Ladder Adjustable 14-inch (Large) is a heavy-duty suspension component designed for sprint cars and high-performance racing applications. This adjustable linkage assembly provides critical load-path support and geometry tuning for serious competition builds where suspension compliance and adjustability directly influence lap times and driver confidence.

Built from chromoly steel and finished in black paint, the 14-inch length places this in the large category for full-size sprint car platforms. The adjustable design allows tuning of suspension geometry angles and ride height compliance without requiring complete component replacement. Hardware and strap mounting provisions are integrated, allowing straightforward installation into existing frame structures. At 2.1 lbs, the component maintains structural rigidity while keeping rotational and unsprung weight minimal—a critical consideration in sprint car setup where every pound affects acceleration and handling balance.

This Jacobs ladder is engineered for teams building or refreshing sprint car suspensions who need proven, adjustable linkage geometry control. Sprint car racing demands frequent setup changes between track conditions, and the adjustable nature of this component allows teams to optimize load transfer and chassis attitude without component substitution. The chromoly construction resists fatigue from repeated cornering loads and impact forces encountered in competitive dirt and asphalt racing.

Allstar Performance's position as a supplier to competitive racing programs means this component meets the durability and geometry standards expected in that environment. The 14-inch size matches common full-size sprint car frame widths and wheelbase proportions, making it compatible with standard cage and suspension layouts.
