Spec Clutch SF465 Stage 5 Full-Metallic Clutch Kit

The SPEC SF465 Stage 5 Clutch Kit is SPEC's most aggressive performance clutch offering, engineered for heavily modified drag race and pulling applications. Built around a full-metallic sintered iron disc with the highest possible friction coefficient, this kit delivers maximum holding power and heat resistance where conventional organic or ceramic clutches simply cannot keep up. Due to its aggressive engagement characteristics, this clutch is not street-friendly and is best suited for dedicated race and performance applications.

Key Features:

• Full-metallic sintered iron disc with maximum friction coefficient for superior holding power
• High-clamp pressure plate for firm, positive engagement (adjustability available on select applications)
• Solid 12-rivet hub assembly — heat-treated for exceptional strength and durability
• Rigid iron disc assembly with unsprung hub design for direct, uncompromising power transfer
• SFI 1.1 Certified — meets sanctioning body requirements for competitive motorsports use
• Ideal for drag racing, tractor pulling, and extreme performance driving
• Made in the U.S.A.

Kit Includes:

• High-clamp pressure plate
• Rigid sintered iron disc assembly
• Throwout bearing (where applicable)
• Installation tool kit

Important Notes: The Stage 5 is not recommended for street driving due to harsh, aggressive engagement. For best results, this kit should be ordered as a custom configuration — consult a SPEC technical specialist to ensure the correct setup for your specific application and power level. SPEC Clutch warrants all products against defects in materials and workmanship for up to 120 days after retail purchase.
