S&S CYCLE Rocker Arm Guardian Kit — Steel, Kit – 18-23 Softail, 17-23 Touring, 17-23 Trike, 17-23 CVO

Upgrade your top end with a complete guardian kit that combines hardened components and serviceable roller rockers for long-lasting valve-train performance. 🔧⚙️

The kit includes roller rocker arms, rocker arm shafts, a rocker arm stud kit, and a head bolt kit — all engineered as direct replacements for worn or broken factory pieces to deliver greater durability and precise fit.

• Forged roller rocker arms with improved geometry and extended bushings to reduce wear and increase rebuild intervals
• 1.640 ratio; capable of .650" maximum valve lift (recommended for cams .550" and greater)
• Hardened, surface-ground shafts and formed threads on head bolts to prevent tower damage
• Heat-treated, cold-formed head bolts with 12-point heads and integral washers for secure fastening; durable black oxide finish and 12-point nuts
• Compatible with stock or CNC heads; rollers eliminate valve thrust and reduce valve-train wear

Designed for high-lift cam applications, this kit extends cylinder head life and lowers maintenance frequency while remaining serviceable and rebuildable for generations. Install studs and safely re-torque nuts to protect rocker towers and keep the top end running strong.
