EPI Performance CFMOTO UForce U10 Pro Secondary Clutch Spring

Description

EPI Performance CFMOTO UForce U10 Pro Secondary Clutch Spring

This secondary clutch spring is designed to work with the CVT clutch system of select CFMOTO UForce models. It serves as a key component for adjusting shift characteristics, belt grip, and overall clutch response to match your vehicle’s operating conditions.

Manufactured by EPI Performance, this spring offers a precise upgrade or replacement option. It allows you to fine-tune engagement and RPM range, helping maintain consistent performance during use.

Ideal for stock setups or modified applications, this spring delivers reliable tension and durability, supporting smooth backshifting and stable operation across varying loads and terrain.

Features

• Precision Tuning: Adjusts clutch engagement and RPM to optimize shift behavior
• Premium Construction: Made from high-quality spring material for long service life
• Consistent Performance: Manufactured to a strict 5% tolerance for reliable spring rates

Specifications

EPI has three spring options for the CFMOTO U10 Pro:

• CFFSS1 (Bright Green): 3″ Load – 172 lbs; 2″ Load – 216 lbs
• CFFSS2 (Pink): 3″ Load – 188 lbs; 2″ Load – 237 lbs
• CFSS3 (Purple): 3″ Load – 203 lbs; 2″ Load – 257 lbs

Design & Construction

The spring is engineered to maintain stable tension under compression and heat, common in CVT systems. High-grade materials resist fatigue and deformation over repeated cycles.

Precision manufacturing ensures each unit matches the specified load values, eliminating inconsistent performance between units.

Performance Benefits

Upgrading or replacing your secondary spring helps reduce belt slip, lower operating temperatures, and improve power transfer efficiency. It brings predictability to how the clutch shifts under acceleration or load.

Proper spring selection aligns your clutch behavior with your specific setup, whether keeping stock specifications or making minor adjustments.

Installation Notes

This spring is sold individually and fits directly into the secondary clutch assembly. Installation follows standard CVT service procedures; professional installation is recommended if you are unfamiliar with clutch components.

Why It Stands Out

This EPI Performance spring combines trusted build quality with precise engineering. It offers a straightforward way to restore factory feel or refine your machine’s shifting characteristics.

With tight tolerances and proven materials, it provides consistent results you can rely on during every ride.
