Straightline Performance Billet Adjustable Weight Kit (78–80g)

The Ultimate Adjustable Clutch Weight System for Serious Tuners

When it comes to clutch calibration, nothing influences performance more than clutch weight selection. The Straightline Performance Billet Adjustable Weight Kit has become one of the most trusted and widely used tuning systems in the snowmobile industry, giving riders the ability to precisely dial in clutch performance for maximum acceleration, optimal RPM control, and peak power transfer.

Manufactured from premium billet material and precision-machined to exact specifications, these weights are designed to provide unmatched tuning flexibility while maintaining the durability required for today’s high-performance snowmobiles.

Each weight is heat-treated to the ideal hardness specification, ensuring long-term durability, consistent wear characteristics, and reliable performance season after season. To further enhance longevity and corrosion resistance, every weight receives a premium yellow zinc plating finish that provides excellent protection against harsh riding conditions.

The Straightline Performance Adjustable Weight Kit utilizes a simple set-screw tuning system that allows riders to make precise weight changes without purchasing multiple sets of clutch weights. Whether you’re compensating for elevation changes, tuning for modifications, adjusting for riding style, or simply chasing maximum performance, these weights make clutch calibration easier than ever.

Designed to cover a broad range of high-horsepower applications, the kit offers an adjustable range from 78 grams to 80 grams right out of the box. For riders requiring even greater flexibility, optional tungsten washer kits are available, extending the tuning range up to an impressive 102 grams.

This makes the kit an excellent solution for turbocharged snowmobiles, big horsepower trail builds, performance applications, and riders who demand precise clutch calibration. The ability to quickly adjust weight mass allows riders and tuners to maintain target RPM and maximize power delivery regardless of horsepower level, riding conditions, or elevation.

Unlike many adjustable systems that can be complicated or time-consuming to tune, the Straightline Performance design was developed with simplicity in mind. The complete tuning package includes everything needed to make adjustments quickly and accurately, making it ideal for both experienced tuners and first-time clutch tuners.

Over the years, this has become one of the most popular clutch weight systems on the market because it works. Riders appreciate the ability to fine-tune clutch performance without constantly purchasing new components, while racers and performance enthusiasts rely on the system’s repeatability and accuracy when every RPM matters.

Whether you’re looking to improve acceleration, maintain peak horsepower RPM, increase consistency, or build the ultimate tuning package, the Straightline Performance Billet Adjustable Weight Kit delivers the flexibility and performance serious riders demand.
