Crower 74733F Features:

Crower 74733F shaft rocker assembly with blue print PS8013 and 1-piece intake stands for 5/8 shaft applications CNC precision-machined from ball race alloy steel, then heat-treated twice and micro-finish ground in-house Fully rollerized precision needle bearing fulcrums help reduce friction, scrubbing, and valve stem side loading Aircraft-quality 12-point nuts and super-secured axles support reliable operation and improved valve control

Shaft Rockers Blue Print 5/8 Shaft, One-piece Intake Stands, Features:

• CNC-machined ball-race alloy steel rockers with 5/8 in. shaft and 1-piece intake stands for precise valvetrain geometry and stable high-RPM operation
• Double heat-treated, micro-finish-ground construction helps reduce wear, maintain alignment, and support consistent rocker performance under demanding engine loads
• Fully rollerized precision needle-bearing fulcrums minimize friction, reduce scrubbing, and help improve valve control while lowering valve stem side loading
• Aircraft-quality 12-point nuts and super-secured axles promote reliable retention, trouble-free operation, and added confidence in performance valvetrain setups
• Blueprint shaft rocker assembly, Part Number 74733F, engineered for reduced frictional losses and smoother motion in performance-oriented valvetrain applications
