Product Description

The McLeod Racing 465310 Max Mass Billet Steel Flywheel is purpose-built for 2012-2018 Jeep Wrangler JK owners running the 3.6L Pentastar V6 with a 6-speed manual transmission. Unlike the factory flywheel, the heavier 45-lb billet steel construction stores significantly more rotational energy, reducing the tendency for the engine to bog or stall when crawling over obstacles, hauling heavy loads, or running oversized tires - the most common complaint from JK owners who have lifted and re-geared their rigs.

Engineered as part of McLeod's Adventure Series, this flywheel is a direct bolt-on replacement that requires no drilling or modification. It is internally balanced to match the factory 3.6L specification and features a 127-tooth ring gear for reliable starter engagement. Whether you're building a dedicated trail rig or want a more confident daily driver, the 465310 is a proven upgrade for JK owners pushing beyond stock capability.
