1. Product Introduction
Original OE Number: A251 320 3013
Product Name: Mercedes-Benz W251 R-Class Front Air Suspension Repair Kit
Installation Position: Front air suspension system,universal for front left and front right, not compatible with rear positions. Exclusively suitable for Mercedes-Benz W251/V251 chassis R-Class models with original Airmatic air suspension. Not applicable for mechanical suspension, rear air suspension and other chassis models.
Product Description: A251 320 3013 is an original factory matching professional repair kit for the front air suspension of Mercedes-Benz classic W251 R-Class luxury business SUVs, a cost-effective repair part for solving common minor air leakage faults of W251 front air suspension. Due to the heavy front suspension load and long-term high-frequency driving of R-Class vehicles, the sealing rubber rings of the original air spring are prone to aging, hardening and failure, resulting in common problems such as front sinking after parking, slight chronic air leakage, unbalanced body height and occasional air suspension alarm. This repair kit adopts 1:1 original sealing specification replication, complete with full sets of special sealing rubber rings, dust-proof accessories and sealing repair components. There is no need to replace the expensive complete air spring assembly. It can accurately repair minor faults such as poor sealing and micro air leakage of air suspension by replacing a full set of sealing accessories. Featuring high fitting accuracy and excellent weather aging resistance, it perfectly adapts to the working conditions of W251 front air suspension, maintains stable air tightness after repair, greatly reduces vehicle maintenance costs and avoids excessive maintenance.
Core Advantages
- Developed in strict accordance with the original A2513203013 front air suspension sealing parameters, with sealing size, accuracy and mounting positions fully consistent with original W251 front air springs, universal for front left and right, supporting non-destructive maintenance without original vehicle structure modification
- Specially solves typical W251 R-Class front air suspension faults: pressure relief caused by aging sealing rings, slight chronic air leakage, front sinking after parking and unbalanced body height, optimized for front suspension long-term load-bearing and seasonal temperature aging working conditions
- Adopts European vehicle-specific high and low temperature resistant high-elastic sealing materials with excellent aging resistance, deformation resistance and pressure resistance, avoiding hardening and secondary air leakage of ordinary repair kits, ensuring long-term stable air tightness
- Low-cost precision maintenance solution, targeting minor sealing faults without replacing the air spring assembly, effectively reducing maintenance costs and improving cost performance for repair shops
- Fully compatible with original Airmatic air suspension electronic control system. After repair, the vehicle body automatic leveling and height sensor data work normally without fault codes, restoring the original factory chassis comfort
- Every product undergoes strict factory air tightness test and weathering aging test with high fitting accuracy and low error rate, suitable for 4S routine maintenance, professional repair shop precision overhaul and cross-border bulk stocking

5. FAQ
Q1: Is A2513203013 universal for front left and front right?
A: Fully universal. The W251 R-Class front air suspension repair kit has no left or right distinction, which can be used for both front left and front right maintenance without position distinction.
Q2: Can it be installed on rear positions or other chassis models?
A: No. The structure, stroke and pressure resistance parameters of front and rear air suspensions are vastly different, and installation on rear axles is strictly prohibited. It only fits W251/V251 R-Class, not applicable for W164/W166 and other chassis models.
Q3: Is it suitable for mechanically suspended R-Class models?
A: No. Mechanical suspension models are not equipped with air suspension pumps, pipelines, control modules and mounting bases, with no installation conditions for air suspension.
Q4: Is computer programming required after replacement?
A: No programming and coding required. Adopting 1:1 original parameter adaptation, only air tightness test, body height calibration and fault code clearing are needed after installation for normal use.
Q5: What symptoms require replacement of this front air spring?
A: This repair kit is applicable to vehicles with only slight chronic front air leakage, front sinking after parking and slight unbalanced body height caused by sealing aging, while the air spring bladder has no cracking, bulging or structural damage. It can perfectly repair minor sealing faults without replacing the assembly. If the air spring has cracking, damage or serious collapse, replacing the air spring assembly is recommended.
Q6: What is the difference between 3013, 3113 and 5613?
A: All are original iterative universal models for W251 front air suspension repair kits with completely consistent sealing parameters and maintenance adaptability, only differing in batch numbers and can be interchanged freely.
