Product Introduction
S1608000 High-Strength Optimized OEM-specs Clutch Master Cylinder for Lifan
Engineered for hydraulic clutch systems, our S1608000 Clutch Master Cylinder delivers precise pedal feel and reliable force transmission. Crafted from forged aluminum with a precision-machined bore, it resists wear and ensures consistent performance under high pressure (tested to 1,500psi). Dual-lip seals prevent fluid leakage, a common failure point, extending service life. Compliant with ISO 7628 standards, this unit undergoes 100,000+ cycle durability testing, mirroring real-world demands. Trusted by aftermarket professionals for its tight tolerance and minimal pedal play, it’s a proven solution for seamless clutch engagement. Compact yet robust, it balances efficiency with longevity—key for heavy-use applications.
Product Advantage
1. High-Strength Forged Aluminum Construction
Crafted from aircraft-grade forged aluminum (not cast), this cylinder reduces weight by 12% vs. standard alternatives while enhancing impact resistance. The precision-machined 0.0015mm-tolerance bore ensures consistent fluid flow, cutting pressure loss by 18% during clutch engagement. Tested to 1,900psi peak pressure—exceeding OEM specs—it resists deformation even under repeated heavy loads, delivering unmatched longevity for high-use applications.
2. Dual-Lip Fluorosilicone Seal System
A game-changer for leak prevention: our proprietary dual-lip seals (pre-coated with PTFE lubricant) eliminate fluid seepage, a leading cause of clutch failure. They maintain 100% leak-free performance through 120,000+ pedal cycles and are compatible with DOT 3/4/5.1 fluids (SAE J1685-certified). This design prevents corrosion and reduces maintenance costs—critical for aftermarket professionals seeking hassle-free solutions.
3. Third-Party Validated Durability
Rigorous ISO 7628 testing proves this cylinder lasts 2.5x longer than generic units: it withstands 160,000 pedal actuations without degrading pedal feel or force output. The chrome-plated piston reduces friction by 22%, resulting in a lighter pedal effort (just 1.2kg force for full disengagement) and consistent clutch performance. Trusted by 80% of our B2B clients for its zero-defect track record.
4. Optimized Hydraulic Precision
Engineered for responsive control: minimal pedal play (<0.8mm) ensures instant clutch feedback, while the high-efficiency bore-to-piston ratio transmits 97% of pedal force to the slave cylinder. This eliminates “mushy” pedal feel—common in low-grade units—and enables smooth, precise gear shifts. Ideal for drivers and mechanics prioritizing performance and consistency.
5. Aftermarket-Compatible Design
While tailored for universal hydraulic clutch systems, this cylinder’s compact footprint (2.1” length x 1.1” diameter) fits 95% of aftermarket master cylinder brackets. Pre-assembled with a brass fittings kit (corrosion-resistant), it reduces installation time by 30% vs. generic parts—making it a go-to for installers valuing speed and accuracy.

Product Uses
Here are specific application scenarios of Clutch Master Cylinder:
1. Daily Commuting Vehicles
Ideal for drivers navigating frequent stop-and-go traffic, our S1608000 thrives in low-speed, high-cycle use. With <0.8mm pedal play and 160,000+ tested pedal cycles, it eliminates “mushy” feedback and slashes maintenance—perfect for commuters racking up 10k+ miles/year. Fluorosilicone seals prevent leaks, avoiding costly roadside repairs and keeping daily drives stress-free. (Data: pedal play, cycle testing; Benefit: low upkeep, reliability)
2. Commercial Fleets (Heavy Loads/Long Hauls)
Built for fleets hauling cargo or running cross-country, this cylinder withstands 1,900psi peak pressure—handling repeated hard clutch engagements without warping. Clients report 40% fewer clutch-related downtime incidents vs. generic units, thanks to forged aluminum resisting heat/fatigue. Ideal for trucks/vans demanding consistency under load. (Data: max pressure, fleet feedback; Benefit: reduced downtime, durability)
3. Performance Enthusiasts (Modifications/Track Use)
Suited for drivers upgrading for sharper shifts, the S1608000 delivers 97% pedal force to the slave cylinder—enabling crisp, precise engagement. A chrome-plated piston cuts friction by 22%, boosting throttle response. Used by hobbyists for track days or spirited driving, it balances OEM reliability with aftermarket performance. (Data: force transmission, friction reduction; Benefit: better shifting, responsiveness)
4. Ride-Hailing & Taxi Services
Tailored for high-mileage use, this cylinder’s ISO 7628-tested longevity (2.5x generic) cuts maintenance costs for taxi fleets. Its compact fit simplifies replacements, while SAE J1685-compliant seals ensure fluid compatibility. 80% of ride-hailing clients praise its zero-defect track record—keeping vehicles on the road longer. (Data: longevity, client feedback; Benefit: cost savings, uptime)
Product Operate Guide
For best results: First, confirm compatibility with your hydraulic system using the 2.1” (53mm) length/1.1” (28mm) diameter. Mount securely with 12-15Nm torque (prevents seal damage/leaks). After installation, bleed air per standard procedures—this ensures <0.8mm pedal play for crisp, responsive shifts. Always use SAE J1685-certified DOT 3/4/5.1 fluid to maximize seal life and consistency. Follow these steps, and you’ll leverage our ISO 7628-tested durability for thousands of trouble-free cycles.
