The RockShox Air Can Upgrade Kit - Linear XL 47.5-55mm SIDLuxe A1+ elevates your SIDLuxe rear shock performance by increasing the positive air volume, delivering a smooth, coil-like ride feel. This upgrade refines the suspension’s sensitivity, especially at the beginning of the stroke, while providing stronger support through the mid-stroke. Whether you’re aiming for lightweight efficiency or uncompromising performance, this kit bridges that gap with seamless tunability for a personalized ride.
Designed for riders who demand precision, the Linear XL upgrade allows you to adjust progression with up to eight Bottomless Tokens, ensuring your suspension matches your terrain and riding style perfectly. The comprehensive kit includes everything needed for installation and servicing, such as the air can, volume spacers, seals, grease, oil, and decals, making it an all-in-one solution for maintaining consistent shock performance.
Compatible with several SIDLuxe models (RS-SIDL-UFA-A2, RS-SIDL-ULT-A1, RS-SIDL-ULT2-A2, RS-SIDL-ULT3-A2), this upgrade kit enhances your mountain bike’s rear suspension responsiveness and control.
