Optimized Title: Primary Clutch Spring for Polaris and Arctic Cat Snowmobile in Green/Pink

SLP's line of drive springs offers you the flexibility to choose a spring that not only provides the engagement you desire, but also delivers the proper peak RPM. These springs are manufactured using only the highest quality Chrome-Silicon wire that has been shot peened to ensure a highly durable and sag-resistant construction.

One such spring in SLP's offering is the green with pink stripe SLP 40-77 primary spring, which is a recommended component in many of SLP's clutch setups. This spring features the following spring rates:

For Arctic Cat models, the spring rate is 150 / 330 pounds, measured at 2 9/16" and 1 5/16" respectively. For Polaris models, the spring rate is 160 / 340 pounds, measured at 2.50" and 1.25" respectively.

To facilitate the proper installation of this SLP primary spring, the use of specialized tools is highly recommended:

1. Primary Clutch Holding Tool 20-202: This tool holds the primary clutch in place, preventing it from turning while removing or installing the clutch on the tapered shaft.
2. Primary Clutch Puller 20-136: This tool is used to remove the primary clutch from the tapered crankshaft.
3. Clutch Press Tool 20-222: This tool compresses the primary or secondary clutch, making the dis-assembly and re-assembly process easier when the clutch is under spring tension.

The use of these specialized tools ensures a smooth and efficient installation process, allowing you to properly maintain and service your vehicle's clutch system.

In conclusion, the SLP 40-77 primary spring, with its high-quality Chrome-Silicon construction and resistance to sag and breakage, is a reliable and recommended component in many of SLP's clutch setups. The availability of specialized tools further enhances the installation experience, ensuring a secure and proper fit for your vehicle's clutch system.
