Disc Pack Metallic 5.5in 3 PL 1-1/4in X 29spl

The Disc Pack Metallic 5.5in 3 PL 1-1/4in X 29spl from TILTON is a precision clutch friction disc assembly engineered for high-performance and racing applications where consistent torque transfer and thermal durability are non-negotiable. This component is purpose-built for drivers and shops upgrading street cars, track-focused builds, and competition vehicles that demand reliable power delivery under extreme load cycling. Whether you're tuning a naturally aspirated engine or running forced induction, a quality disc pack directly impacts drivability, launch control, and overall drivetrain longevity.

This metallic friction disc features a 5.5-inch diameter with three friction plates and a 1-1/4-inch hub bore machined to 29-spline engagement geometry, delivering maximum surface area for heat dissipation and load capacity. Metallic friction material offers superior bite and thermal stability compared to organic compounds, making it ideal for drivers who repeatedly subject their clutch to full-throttle engagements, track days, or drag racing. The multi-plate design increases overall clamping force efficiency while the spline configuration ensures positive drive without slippage—critical for maintaining traction control calibration and avoiding destructive shock loads on transmission input shafts and engine block bosses.

This TILTON disc pack is ideal for tuners, race teams, and serious enthusiasts restoring or upgrading manual transmission clutch assemblies in performance platforms. Compatibility depends on your specific clutch pressure plate, flywheel, and transmission spline design—verify that your release mechanism supports the firm engagement characteristics of metallic friction material before purchase. Installation requires proper alignment tools and a clutch bleeding procedure; professional installation is recommended to ensure correct stack height, pressure plate clamp load, and long-term reliability. Pair this with a matched pressure plate, throw-out bearing, and alignment tools for a complete clutch refresh that maximizes grip and minimizes pedal modulation effort.
