RPM RMK 850 / 800 NA TITANIUM Polaris Primary Clutch Cover Bolts (QTY 6) OEM # 7518349 M6x1.0x57mm

Polaris Primary Clutch Cover Bolts (QTY 6)

Lighten rotating mass, eliminate rust, and secure your primary clutch cover plate with RPM’s Grade 5 Titanium Primary Clutch Cover Bolt Kit! Engineered as a direct, heavy-duty replacement for soft factory OEM hardware (OEM Part #7518349), this 6-piece bolt set fits a wide range of Polaris 600, 800, and 850 snowmobiles, as well as Polaris RZR, General, Ranger, and Ace UTV platforms.

Precision-machined from aerospace-grade Grade 5 (Ti-6Al-4V) Titanium, these M6 x 1.0 x 57mm hex flange bolts handle severe clutch harmonics, extreme rotational RPM, and heavy spring pressures without stretching, backing out, or shearing. Upgrading to titanium ensures your clutch cover remains evenly torqued, eliminating cover flex and prolonging clutch bushing life while shedding rotational weight.

Technical Specifications & Installation Guidelines:

⚠️ TORQUE & INSTALLATION CAUTION:

• Torque Reduction Rule: When replacing factory steel hardware with Grade 5 Titanium, reduce the manufacturer's specified torque rating by 10% to 15% to prevent thread fatigue or over-stretching the fastener in aluminum clutch components.

• Threadlocker: Always apply a drop of Blue Medium-Strength Loctite to clean threads prior to torquing down to safeguard against vibration backing-out from engine harmonics.
