Mopar Adjustable XS Starter

The POWERMASTER Mopar Adjustable XS Starter is purpose-built for classic and modern Mopar V8 engines that demand reliable cold-start performance and extended cranking durability. This high-torque starter replaces OEM units on Mopar V8 platforms, delivering the extra cranking force needed in high-compression, modified, or heavily optioned vehicles where factory starters fall short. Designed for enthusiasts and professional rebuilders, the XS model addresses the real-world challenge of starting tough engines consistently—whether on the street, strip, or in storage after seasonal layup.

The adjustable XS starter incorporates a 4.4:1 gear reduction ratio that amplifies cranking torque while maintaining efficient power draw—a key advantage over stock starters in high-demand applications. The natural-finish nose cone design ensures proper clearance on tight engine bays and integrates seamlessly with Mopar V8 bellhousings and mounting pads. Weighing 9.25 pounds with compact dimensions of 7.4 x 5.5 x 12.5 inches, this unit minimizes weight while maximizing power output, making it ideal for both restoration accuracy and performance upgrades. The adjustable mounting bracket allows fine-tuning of gear mesh engagement, extending service life and reducing noise during engagement.

The POWERMASTER Mopar Adjustable XS Starter suits restorationists restoring original Mopar muscle cars, engine builders upgrading tired factory starters, and off-road enthusiasts running marginal fuel mixtures that require harder cranking. Installation is straightforward on any Mopar V8 platform—bolt-in compatibility requires only standard hand tools and a basic understanding of starter geometry. This starter pairs well with high-output alternators and upgraded battery systems for maximum reliability in demanding conditions. Whether you're troubleshooting chronic no-start issues or preemptively upgrading before a long road trip, the adjustable XS delivers the margin of safety that separates occasional starts from guaranteed starts.
