1014001680 Rear Spring Upper Support for Geely MK

Product Introduction

1014001680 Rear Spring Upper Support for Geely MK

Our Rear Spring Upper Support is a critical suspension component connecting the rear spring to the vehicle body. Crafted from high-strength alloy steel and durable rubber composites, it stabilizes the rear spring, absorbs road vibrations, and reduces cabin noise.

Its core function is to distribute spring pressure evenly, maintaining proper suspension alignment during acceleration, braking, or rough terrain. Suitable for various car models, it enhances ride comfort and protects adjacent suspension parts from excessive wear, ensuring reliable performance in daily and heavy-duty use.

Product Advantage

1.High-Strength Composite Material Construction

Made of automotive-grade 45# alloy steel (tensile strength ≥900MPa) and EPDM anti-aging rubber, the Rear Spring Upper Support resists deformation even under 5000N continuous load. The rubber component passes 3000-hour aging tests, ensuring 5+ years of service life—20% longer than ordinary rubber supports.

2.Efficient Rear Suspension Vibration Absorption

Integrated multi-layer damping structure reduces 65% of road vibration transmitted to the vehicle body, significantly lowering cabin noise during driving. It maintains stable performance in -40°C to 120°C extreme temperatures, solving the problem of hardening or cracking of supports in harsh environments.

3.Precision Machining for Universal Fit

With CNC-machined mounting holes (tolerance ±0.02mm), it fits 98% of mainstream passenger cars and SUVs (verified by 6000+ vehicle compatibility tests). The direct bolt-on design requires no modification, cutting installation time by 35% compared to non-universal Rear Spring Upper Supports.

4.Superior Corrosion & Wear Resistance

The alloy steel surface adopts electrophoretic coating (thickness 8-10μm), passing 500-hour salt spray tests (complying with ISO 9227 standards). It effectively resists rust from rain, snow, or coastal humidity, while the rubber’s wear resistance reduces friction damage with the rear spring.

5.ISO/TS 16949-Certified Quality

Produced in our factory with 18 years of suspension part manufacturing experience, each Rear Spring Upper Support undergoes 15 quality inspections (including load, vibration, and dimensional tests). The pass rate reaches 99.8%, matching OEM quality at a more cost-effective price.

Product Uses

Here are specific application scenarios of Rear Spring Upper Support:

1.Daily Urban Commuting

Perfect for city drives with frequent stops, speed bumps, and tight parking. It absorbs small vibrations from uneven urban roads, reduces cabin noise, and keeps the rear spring stable—preventing premature wear from daily small bumps.

2.Long-Distance Highway Travel

Stabilizes the rear suspension during extended high-speed runs. Minimizes rear spring 晃动 (sway) caused by highway turbulence, maintains consistent suspension alignment, and reduces fatigue on connected parts like control arms.

3.Family Car Load-Bearing Scenarios

Ideal when carrying passengers or cargo (e.g., weekend trips, grocery runs). Distributes the rear spring’s pressure evenly, avoiding deformation from extra weight and ensuring stable handling even with a full load.

4.Rural/Rough Road Driving

Shields the rear suspension from strong impacts on gravel, dirt, or potholed rural roads. Its durable material and shock-absorbing design protect the rear spring and vehicle body from damage caused by uneven terrain.

5.Aging Vehicle Maintenance

Great replacement for worn original Rear Spring Upper Supports (common in cars over 5 years old). Restores factory-level suspension performance, eliminates abnormal noises from loose supports, and fits DIY or professional repair needs.

Product Operate Guide

1. When the vehicle comes to a complete stop, pull the handbrake, use a jack to lift the rear wheel, and secure the support bracket; Remove the rear wheel and wheel arch guard to expose the upper support of the rear spring.

2. Use a wrench to remove the fixing bolts, take out the old support, and clean the installation position of impurities and rust.

3. Align the installation holes of the new support, manually pre tighten the bolts, confirm the position is correct, and tighten with a torque of 30-35N · m.

4. Reinstall the protective plate and rear wheel, lower the vehicle, and check for any looseness or abnormal noise.
