BMP 05-BLACKTS Secondary Clutch Spring Black Torsion Style

The BMP 05-BLACKTS is a high-performance torsion-style secondary clutch spring designed for snowmobile and UTV applications. This black-coded spring is engineered to precise specifications by Bikeman Performance to optimize clutch performance and belt life.

Key Features:

• Torsion-style design allows for adjustable spring tension and improved shift characteristics
• Enables full overdrive shift out, unlike stock springs that often coil bind
• Black color coding for easy identification and tuning reference
• Manufactured to exacting specifications for consistent performance
• Adjustable design allows fine-tuning of upshift and backshift rates
• Helps reduce belt temperatures and extend belt life

Torsion springs are a key component in BMP's clutch conversion kits, replacing stiff stock secondary springs that limit full clutch shift. The adjustable nature of this spring allows riders to dial in their clutch setup for different modifications, altitudes, and riding conditions. Works with BMP torsion conversion helixes on 2005 and newer secondary clutches.
