Straightline Performance Ski-Doo / Lynx QRS Jackshaft Alignment Shim Kit

The Straightline Performance QRS Jackshaft Alignment Shim Kit precisely repositions the QRS jackshaft approximately 3 mm to achieve improved clutch alignment, smoother power transfer, and longer belt life. Complete with precision-machined shims for both the bearing side and chaincase gear side, this kit provides a simple, effective solution for optimizing drivetrain efficiency on Ski-Doo and Lynx models equipped with QRS secondary clutches.

Precision Belt Alignment for Maximum Clutch Performance

Correct Jackshaft Alignment in Minutes

Improve Belt Life, Clutch Efficiency, and Power Transfer

The Straightline Performance QRS Jackshaft Alignment Shim Kit is designed to correct one of the most overlooked areas of clutch performance—jackshaft alignment. By allowing the QRS jackshaft assembly to be moved outward approximately 3 mm, this precision shim kit helps achieve proper clutch alignment for improved belt efficiency, smoother shifting, and longer belt life.

The kit includes precision-machined shims for both the jackshaft bearing side and the chaincase gear side, allowing the entire shaft assembly to be relocated while maintaining proper bearing and gear alignment. The result is a more accurately aligned primary-to-secondary clutch relationship, reducing unnecessary belt side loading and improving overall drivetrain efficiency.

Proper clutch alignment is critical on both stock and high-horsepower machines. Even small alignment issues can increase belt wear, create excess heat, reduce efficiency, and negatively affect clutch performance. The Straightline Performance Shim Kit provides a simple, effective solution to fine-tune your drivetrain for maximum performance.

Manufactured from premium materials and precision machined for an exact fit, the kit installs easily during clutch or chaincase service and requires no permanent modifications to the chassis.

Whether you’re building a race sled, tuning a high-performance machine, or simply looking to maximize belt life and clutch performance, the Straightline Performance Jackshaft Alignment Shim Kit is an excellent upgrade.
