Left Front Torsion Arm Sprint Car

The Left Front Torsion Arm Sprint Car (Part No. SC-SU-0115) is a precision-engineered suspension component designed for micro and mini sprint racing applications. Built from polished aluminum, this driver-side front torsion arm measures 18.75 inches in length and delivers the geometry needed for consistent handling during high-speed competition. Hardware is included, eliminating the need for separate fastener sourcing and ensuring compatibility with Triple X chassis systems.

Torsion arm design plays a critical role in sprint car dynamics, controlling wheel travel and lateral load transfer during cornering and acceleration. The aluminum construction on this component balances strength with weight reduction—a key consideration in micro sprint classes where total vehicle weight directly impacts acceleration and fuel efficiency. Polished finish protects against corrosion while providing visual clarity for pre-race suspension checks. At 1.7 lbs, this arm minimizes unsprung weight without sacrificing structural integrity required for competitive racing loads.

Micro and mini sprint racers depend on chassis components that maintain precise geometry lap after lap. This left front arm is built for competitors who demand consistency during feature events and heat races. Whether you're upgrading worn suspension geometry, rebuilding after a season, or establishing a baseline setup, this arm integrates directly into Triple X front suspensions. Complete hardware inclusion means faster turnaround in the pits and reduced downtime between rounds.

Sprint car suspension geometry is unforgiving—even small deviations in arm length or angle affect steering response and tire wear patterns across an entire race night. OEM-specification replacement and upgrade arms ensure your setup remains predictable as you dial in weight transfer and cornering balance.
