14+ 3.6L Pentastar Cart to Spin on Adapter

The 14+ 3.6L Pentastar Cart to Spin on Adapter by Baxter Performance is a precision engine accessory designed for Chrysler, Dodge, and Jeep owners who demand reliable power steering or alternator pulley solutions. This adapter bridges the gap between modern Pentastar V6 engines and aftermarket or custom-configured serpentine belt systems, making it essential for engine swaps, performance builds, and accessory upgrades. Whether you're customizing a late-model platform or restoring vintage harness compatibility, this cart-to-spin-on design eliminates the need for costly custom machining while maintaining OEM fit and function.

Baxter Performance engineers this adapter with precision-machined construction to ensure zero run-out and balanced operation under sustained load. The spin-on interface tolerates both stock and upgraded pulley diameters, allowing seamless integration into high-output alternator or power steering pump configurations without belt slip or harmonic vibration. At just 2.07 lbs, the compact 3.5 x 3.25 x 8-inch footprint minimizes packaging interference while delivering the structural rigidity required for long-term reliability in supercharged or turbocharged Pentastar applications. The adapter's design prevents common failure modes like pulley walk and bearing preload drift.

This adapter suits engine builders, performance shops, and DIY enthusiasts upgrading 2014 and newer 3.6L Pentastar platforms across Jeep Wrangler JK/JL, Cherokee KL, Grand Cherokee WK2, Dodge Durango, Ram trucks, and Chrysler 300/Pacifica models. Installation requires basic hand tools and familiarity with serpentine belt systems; no special equipment or tuning adjustments are necessary. Pair this with performance pulleys, high-amp alternators, or hydraulic power steering upgrades to unlock the full potential of your Pentastar build.
