Chrysler Lever Clutch 11in x 1-3/16in 18spl

The RAM Clutch Chrysler Lever Clutch 11in x 1-3/16in 18 Spline (part number 88504HDX) is a single-disc, organic friction clutch assembly engineered for Mopar-equipped vehicles requiring precise engagement and reliable torque transfer. This HDX-grade clutch kit delivers the holding power and modulation expected in street and performance driving applications where stock clutch capacity falls short of demand.

The 11-inch diameter disc with 1-3/16-inch by 18-spline hub geometry matches Chrysler's OEM input shaft specifications, ensuring direct bolt-on compatibility without adapter plates or driveline modifications. The sprung hub design absorbs driveline shock and vibration, reducing noise and protecting synchronizers during gear changes. Organic friction material provides progressive engagement characteristics—a key advantage over ceramic alternatives in street-driven vehicles where smooth pedal response and driver feedback matter as much as holding capacity. At 23.65 lbs, the assembly balances thermal mass for heat dissipation with rotational inertia control.

This clutch is specified for Chrysler, Dodge, and Plymouth models with Mopar bellhousings and manual transmissions. It serves builders upgrading from factory clutches to handle increased engine output—whether from bolt-on modifications, carburetor tuning, or forced induction—without compromising daily drivability. RAM Clutch's HDX line positions this kit in the performance-street segment: significantly stronger than original equipment while remaining user-friendly for road duty and occasional track use.

Verify bellhousing and input shaft spline count before ordering to confirm compatibility with your specific Mopar application. Installation requires a clutch alignment tool and proper torque specs for pressure plate bolts.
