As a key structural component of the front aerodynamic and underbody protection system for Tesla Model Y, this CFN-branded right-hand (RH) lower wing bracket is engineered to match OEM specifications, with core functions focused on "aerodynamic precision + structural load-bearing + underbody corrosion resistance"—upholding CFN’s quality standards for EV-specific structural parts:
- Aerodynamic Stability Maintenance: Serves as the exclusive mounting base for the Model Y’s front lower wing (RH side), ensuring the wing retains its factory-calibrated 3° downward angle relative to the underbody. This preserves the vehicle’s original aerodynamic efficiency (maintaining a drag coefficient of 0.23, consistent with OEM performance) and minimizes high-speed wind noise (≤62dB at 120km/h).
- Dynamic Load Resistance: Constructed with CFN’s reinforced 500MPa high-strength stamped steel, it withstands front-end dynamic stresses—including aerodynamic pressure (up to 850N at 130km/h), impact from road debris (e.g., gravel, small curbs), and underbody vibrations. It prevents the lower wing from shifting or detaching during daily commuting or light off-road use.
- Integrated Underbody Protection: Features a CFN-exclusive 5mm-thick PP+GF20 (polypropylene + 20% glass fiber) shielding, molded directly onto the steel bracket. This shielding blocks road salt, mud, and water from infiltrating the bracket’s connection points to the front subframe, avoiding corrosion and extending the component’s service life.
Replace this CFN RH lower wing bracket immediately if you observe the following issues, indicating wear or failure:
- Lower Wing Misalignment: A visible gap (＞3mm) between the RH lower wing and underbody, or the wing tilting upward/downward (uneven with the LH wing)—caused by bracket bending or broken mounting tabs.
- Bracket Damage/Corrosion: Red rust on the steel base (spreading over 10mm²), cracked PP+GF20 shielding, or deformed bracket edges—signaling loss of structural integrity or risk of subframe corrosion.
- Aerodynamic Abnormalities: Increased front underbody wind noise, or a ＞5% drop in driving range (due to elevated drag)—resulting from the bracket’s failure to hold the wing in its aerodynamic position.
- Loose Mounting: Rattling from the front underbody over bumps, or ＞2mm of wing movement when pushed lightly—caused by stripped fastener inserts or loose subframe connections.
- 1× CFN right-hand lower wing bracket (1551936-S0-B)
- 4× 304 stainless steel mounting bolts (M8×25mm, OEM-spec with lock washers)
- 2× Plastic push clips (for securing shielding to underbody)
- 1× Installation guide (with underbody access diagrams + alignment marks)
- 1× Anti-corrosion grease packet (for bolt threads)
- Socket wrench set (10mm, 13mm)
- Torque wrench (0-50 Nm range)
- Plastic trim removal tool (for underbody splash guard)
- Jack + jack stands (for vehicle lifting)
- Safety Preparation: Lift the front of the vehicle using the front subframe jack point; secure with jack stands. Remove the front underbody splash guard (6 plastic push clips) to expose the RH bracket mounting area.
- Old Bracket Removal: If replacing, remove the 4 RH bracket bolts (10mm socket) and disconnect the lower wing—note the wing’s OEM alignment marks to avoid mispositioning with the new CFN bracket.
- Alignment Check: Align the CFN bracket’s holes with the subframe’s threaded inserts; ensure the PP+GF20 shielding faces downward (toward the road) for optimal debris protection.
- Torque Setting: Tighten bolts to 18±2 Nm (Tesla factory spec)—over-tightening strips subframe threads; under-tightening causes bracket movement. Reinstall the splash guard after verifying alignment.
- Warranty: 3-year/60,000-kilometer warranty (whichever comes first), covering steel corrosion (beyond normal wear), bracket bending (no impact damage), or shielding cracking (excludes collision/off-road abuse).
- Technical Assistance: CFN’s EV structural specialists offer email/chat support for installation (e.g., splash guard removal, alignment verification) and troubleshooting.
- Quality Guarantee: 30-day free replacement/refund for incompatible or defective brackets (unused, original packaging required).
- Maintenance: Inspect every 15,000km—clean shielding with a high-pressure washer (avoid direct spraying on bolts) to remove mud/debris.
- Pair Replacement: For balanced aerodynamics, replace RH (1551936-S0-B) and LH (1551935-S0-B) brackets together if both show wear—mixing old/new causes uneven wing alignment.
- Bulk Inquiries: Repair shops/fleets contact CFN’s commercial team for bulk pricing—custom 10-unit packaging and delivery schedules available.
