COMP Cams 3521CPG Composite Coated Camshaft Bearing Set 2.124" Big Block

The COMP Cams 3521CPG Composite Coated Camshaft Bearing Set is engineered for 2.124-inch journal big block applications, providing superior protection and lubrication in high-performance engine builds. This bearing set features an advanced fluoropolymer composite coating that delivers exceptional performance under extreme conditions.

Key Features:

• Fluoropolymer composite coating provides self-lubricating properties for enhanced protection
• Retains engine oil on bearing surface even under extreme heat and pressure conditions
• Designed for 2.124-inch (2.125") camshaft journals on big block Chevrolet engines
• Excellent protection during engine start-up when oil starvation is most likely to occur
• Advanced coating technology reduces friction and wear for extended bearing life

The composite coating acts as a lubricant itself, making these bearings ideal for high-performance and racing applications where momentary oil starvation can cause catastrophic engine damage. Whether you're building a street performance engine or a dedicated race motor, these cam bearings provide the protection and durability your engine demands.
