Brake Lathe Rotor Silencer Kit - 2 Non Vented 9.25" Silencer Bands & 4 Ventilated Rotor Springs with Rubber Sleeves, Fit for Ammco 9800 6922, Replace SB9800 909800 906922

Dual Silencer System for Complete Noise Reduction​ - Combines ​4-pack SB9800 Ventilated Rotor Spring Silencers​ and ​2-pack 9.25" Non-Vented Rotor Silencer Bands​ to eliminate vibration and noise during all types of rotor cutting. Achieve smoother operation on ​both ventilated and solid rotors​ – ideal for professional workshops and DIY projects. ​Universal Brake Lathe Compatibility​ - Designed to fit ​most major brake lathe models. The SB9800 springs target ventilated rotors, while the 9.25" bands handle large non-vented rotors – making this kit a versatile, all-in-one solution for every job. ​Premium Materials for Long-Lasting Performance​ - SB9800 springs made of ​high-grade spring steel​ resist wear under high-frequency cutting. 9.25" bands use ​durable, corrosion-resistant rubber​ – ensuring extended service life and reduced replacement costs. Easy Installation & Time Savings​ - Both components feature ​flexible, tool-free designs: Simply attach springs to ventilated rotors or swap bands for non-vented rotors in seconds. Minimize setup downtime and maximize workshop efficiency. Complete Kit + Reliable Support​ - Includes ​4 SB9800 Spring Silencers + 2 Silencer Bands (9.25")​​ – perfect for bulk servicing needs. Backed by responsive customer support for compatibility checks or troubleshooting.

• This kit includes 2 pieces of 9.25" non-vented (solid) rotor silencer bands and 4 pieces of ventilated rotor springs with rubber sleeves. The springs are steel-constructed with rubber sleeves for vibration damping, and the silencer bands are made of natural rubber for noise reduction during brake rotor machining
• Designed for use with brake lathes in automotive brake repair and rotor resurfacing operations. The ventilated rotor springs suit machining of ventilated (vented) brake rotors (14 inches and above), while the non-vented silencer bands fit non-vented (solid) brake rotors (9 inches to 13 inches)
• Fit for Ammco brake lathe models, and compatible with accessories from The Main Resource, MT-RSR, Hennessy Industries, SPC Performance. Replaces part numbers: Ventilated rotor springs - SB9800, 9800, 909800, AA9800, 09800; Non-vented silencer bands - 6922, 906922, AP6922, 90194
• The ventilated rotor springs provide stable clamping force to minimize vibration and high-frequency noise during ventilated rotor machining. The non-vented silencer bands absorb vibration and reduce noise for solid rotor machining, helping improve the surface finish of brake rotors
• The quantity of ventilated rotor springs can be adjusted to fit different ventilated rotor diameters. The 9.25" non-vented silencer bands are designed for standard non-vented rotors and install on most brake lathe rotor clamps. The kit is easy to install and remove for routine brake lathe maintenance
