Excess 10mm GC 351 Rear Axle

Product Overview The Excess 10mm GC 351 Rear Axle is a replacement axle engineered for Excess GC (new generation post-2014) rear hubs. The 10mm diameter axle with 351mm total length accommodates standard BMX 3/8" bolt dropouts. Precision-manufactured to exact Excess specifications, it delivers reliable performance across racing and training applications.

Key Features

• 10mm Diameter – Standard BMX rear axle size compatible with 3/8" bolt dropouts; universal compatibility across most BMX frames
• 351mm Length – Full-length axle accommodates both hub sides with proper dropout spacing; engineered for consistent hub geometry
• GC Generation Compatibility – Designed specifically for Excess GC (new generation) rear hubs manufactured after 2014; precision fit ensures proper bearing seating and hub function
• Precision Threading – Exact thread specifications match Excess GC hub cones and lockring; eliminates cross-threading and ensures secure component retention
• Durable Steel Construction – High-strength steel resists bending and maintains straightness under racing loads and impacts
• Direct Replacement – Drop-in compatibility with original Excess GC axles; no modification required for installation

Technical Specifications

• Diameter: 10mm
• Length: 351mm total
• Bolt Standard: 3/8" (standard BMX)
• Material: Steel
• Hub Compatibility: Excess GC (new generation, post-2014) rear hubs only
• Threading: Excess GC standard cone and lockring compatible

Compatibility and Ideal Use Cases

• Fits: Excess GC rear hubs (new generation, manufactured after 2014)
• Best For: Axle replacement due to bending, cracking, or damage; hub rebuild or reassembly; drivetrain upgrades
• Ideal Riders: All skill levels; those maintaining or upgrading Excess GC rear hubs
• Installation Requirement: Intermediate mechanical knowledge; hub disassembly and reassembly needed; requires cone and lockring adjustment
• Not Recommended For: Pre-2014 Excess GC hubs (use older generation axles); non-Excess hubs or incompatible hub standards

Installation Notes Remove rear wheel and disassemble hub from old axle. Clean axle seat and threads on new axle before installation. Install new axle through hub body, aligning splines with cassette body. Thread cones onto both sides hand-tight, then adjust for minimal bearing play with smooth rotation. Lock cones with lockrings, tightening progressively in alternating directions (left-right) to ensure even bearing preload. Verify smooth wheel rotation without binding or play before final wheel assembly.

Maintenance Notes Axle straightness is critical for smooth hub operation and wheel trueness. If axle becomes bent, replacement is recommended over straightening, as bent axles may cause uneven bearing wear and inconsistent hub performance. Periodically inspect axle threading for damage; replace if threads become stripped or cross-threaded.

Performance Note Properly installed and adjusted axle with appropriate bearing preload ensures responsive hub performance critical for competitive racing and smooth drivetrain operation.

Compatibility Reminder Compatible with Excess GC (new generation, post-2014) rear hubs only. Verify your hub generation before purchase—incompatible with pre-2014 GC hubs or other Excess rear hub series.
