The Radflo 2.5 Nitro Steel Shaft Replacement (7/8) is a direct replacement shaft designed for Radflo 2.5 shock absorbers utilizing a 0.875 shaft diameter with 8", 10", 12", 14", 16", or 18" travel length options. Built to restore strength, smooth operation, and long term durability, this mirror polished Nitro Steel rod is engineered for extreme off-road conditions.

If your existing shaft has been bent, scored, or damaged from hard racing or trail abuse, this replacement allows you to rebuild your shock properly without replacing the entire unit. Manufactured to Radflos exact tolerances, it ensures proper seal engagement, smooth cycling, and consistent damping performance.

Designed for high side load strength and harsh off-road environments, the Nitro Steel shaft provides exceptional durability while maintaining precise surface finish for extended seal life.

Tech Insight

The shock shaft is a critical structural component that must withstand extreme compression loads, side loading, and repeated high-speed cycling. Nitro Steel provides superior tensile strength and durability compared to standard steel shafts, while the mirror-polished surface ensures proper sealing and long service life.

Replacing a damaged shaft restores correct sealing surface integrity, prevents oil leakage, and maintains consistent damping performance. Because Radflo shocks are fully rebuildable, replacing the shaft is a cost-effective way to return your suspension to race-ready condition.
