Boost your suspension’s durability and performance with our Rear Shock Shaft Upgrade Kit, designed to replace the factory 7/8" rear shock shaft with a high-strength 1" shaft. Built for aggressive riding and demanding terrain, this upgrade delivers increased stiffness, improved damping control, and long-term reliability.
Key Features:
Heavy-Duty Shaft Upgrade: Replaces the OEM 7/8" shaft with a robust 1" shock shaft for enhanced strength and resilience.
Improved Performance: The larger diameter reduces flex under extreme loads, improving shock consistency and feel.
Precision Engineering: Machined to exact tolerances for a direct fit into the factory rear shock body (may require minor modification).
Race-Ready Strength: Designed for riders who demand more from their suspension — whether it’s dunes, desert, or track.
Complete Kit: Includes 1" shock shaft, upgraded seal head components, and all necessary installation hardware.
Why Upgrade?The stock 7/8" shaft is fine for stock power and moderate use — but when you start riding harder, adding weight, or pushing big power, it becomes a weak point. Upgrading to a 1" shaft gives you the strength and stability needed to handle harsh landings and high-speed abuse without compromise. *Please note that for the Pro R Dynamix will come with a Shock Therapy Shock Guard replacement!*
