1014001681 Rear Spring Lower Support for Geely MK

Product Introduction

1014001681 Rear Spring Lower Support for Geely MK

Our Rear Spring Lower Support is a vital suspension component that links the rear spring to the vehicle’s rear axle or frame. Made of high-strength carbon steel (for structural stability) and wear-resistant rubber (for damping), it balances load-bearing and vibration reduction.

Its core function is to support the rear spring’s weight, evenly distribute pressure to the axle, minimize road vibration transfer to the body, and keep the suspension aligned during braking or turning. Suitable for most passenger cars and SUVs, it prevents spring misalignment and protects adjacent parts, ensuring stable, long-lasting driving performance.

Product Advantage

1.High-Strength 50# Carbon Steel Structure

Our Rear Spring Lower Support uses automotive-grade 50# carbon steel (tensile strength ≥1000MPa) for the main body, withstanding 5500N continuous load without deformation. The integrated stamping process enhances structural rigidity, and it passes 250,000 fatigue cycles (under 3500N dynamic load)—30% longer service life than ordinary steel supports, ensuring long-term rear suspension stability.

2.Dual-Layer Rubber Damping Design

Equipped with high-density NBR rubber (Shore A hardness 80±5) in a dual-layer structure, it attenuates 70% of road vibration transmitted to the rear axle. The rubber maintains elasticity in -45°C to 130°C extreme temperatures, solving the problem of hardening/cracking in harsh climates and improving ride comfort.

3.CNC-Machined Universal Fit

With CNC-machined mounting holes (tolerance ±0.03mm), this Rear Spring Lower Support fits 99% of mainstream passenger cars/SUVs (verified by 7000+ vehicle tests). No drilling or modification needed—installation time is 40% shorter than non-universal supports, ideal for garages and DIY users.

4.Superior Corrosion Resistance

The steel surface adopts 10-12μm electrophoretic coating, passing 600-hour salt spray tests (exceeding ISO 9227 standards). It resists rust from rain, snow, and coastal humidity, keeping the support intact for 6+ years. The rubber’s anti-oxidation formula also prevents aging from UV exposure.

5.ISO/TS 16949-Certified Quality

Produced in our 20-year-experience suspension part factory, each Rear Spring Lower Support undergoes 18 quality checks (load, vibration, dimension). The pass rate reaches 99.9%, matching OEM performance while offering 25% lower cost—reliable for both repair shops and individual car owners.

Technical Parameters

1.Material Composition

Rear Spring Lower Support main body adopts 50# carbon steel, with tensile strength ≥1000MPa and Brinell hardness 190-230HB for strong load-bearing; the rubber layer uses NBR rubber (Shore A hardness 80±5) that resists -45°C to 130°C extreme temperatures; the surface is coated with 10-12μm electrophoretic paint, with adhesion ≥4B to prevent corrosion.

2.Structural Dimensions

Total length of the support is 95±0.3mm; mounting hole diameter is 12mm (tolerance ±0.03mm) for precise alignment with OEM positions; rubber layer thickness is 18±0.5mm to ensure effective damping; overall weight is 240±10g, matching the original part’s weight distribution.

3.Performance Metrics

Static load capacity reaches ≥5500N without permanent deformation; fatigue life is ≥250,000 cycles under 3500N dynamic load (complying with ISO 13003-2017); vibration attenuation rate is ≥70% in 10-200Hz frequency range; salt spray resistance passes ≥600-hour tests (meets ISO 9227-2017), no red rust occurs.

4.Compatibility

Suitable for 99% of mainstream passenger cars and SUVs, with compatibility verified for over 7000 vehicle models; installation adopts direct bolt-on design, perfectly matching OEM mounting holes—no drilling or modification is required, reducing installation time.

5.Certifications & Compliance

Complies with ISO/TS 16949 automotive quality standards (IATF 16949:2016 certified); meets RoHS 2.0 environmental requirements, free of restricted substances like lead and cadmium; each unit undergoes 18 full-item inspections (including load, dimension, and vibration tests) before leaving the factory, with a pass rate of 99.9%.

Product Uses

Here are specific application scenarios of Rear Spring Lower Support:

1.Daily Urban Commuting

Ideal for city drives with frequent speed bumps, potholes, or stop-and-go traffic. The Rear Spring Lower Support absorbs small vibrations from uneven roads, reduces cabin noise, and keeps the rear spring stable—preventing premature wear from daily minor impacts and ensuring smooth rides.

2.Family Car Load-Bearing Scenarios

Perfect when carrying passengers, luggage, or groceries (e.g., weekend trips, shopping runs). It evenly distributes the rear spring’s pressure, avoids spring misalignment or deformation under extra weight, and maintains rear suspension stability for safe, balanced driving.

3.Rural & Rough Terrain Driving

Shields the rear suspension from strong impacts on gravel roads, dirt paths, or rural potholes. Its high-strength steel body and durable rubber layer resist damage from uneven terrain, protecting the rear axle and spring from excessive stress.

4.Vehicle Maintenance & Replacement

Great for replacing worn, cracked, or rusted original Rear Spring Lower Supports (common in cars over 60,000 miles). It fits 99% of mainstream models, uses direct bolt-on installation—no modification needed—suitable for professional garages or DIY repairs.

5.Extreme Weather Conditions

Performs reliably in rain, snow, high heat, or freezing temperatures. The corrosion-resistant electrophoretic coating prevents rust from moisture, while the NBR rubber layer stays elastic between -45°C to 130°C, ensuring consistent suspension performance.

Product Operate Guide

1. Pre installation check (30 seconds)

Operation: Verify the OE number laser engraved on the brake pad backing plate

Warning: Clean the contact surface of the brake disc with the accompanying ethanol cotton pads (to prevent abnormal noise)

Tip: Scan the packaging QR code to obtain a 3D disassembly animation

2. Non destructive installation techniques

Operation: Insert brake pads pre coated with noise reducing paste (do not touch the friction surface)

Tool: Use C-shaped calipers to compress the piston (saving 90% effort)

Standard: The installation of the snap spring requires a "click" sound confirmation (anti trip test)

3. Key debugging nodes

Operation: After loading, press the brake pedal 20 times to activate the self positioning system

Validation: No brake warning light on the instrument panel+no metal friction sound when braking in place

Assist: Use decibel testing app to detect noise<35dB (iOS/Android compatible)

4. Intelligent running in strategy

Operation: Avoid sudden braking>0.5G for the first 200 kilometers (G value record sticker attached)

Monitoring: Wheel hub temperature ≤ 120 ° C after continuous braking (detected by infrared thermometer)

Guarantee: Contact video customer service immediately for abnormal vibrations (24/7 multilingual support)
