2463210206 BEMWQ Auto Suspension Rubber Buffer for Mercedes Benz X156 W246 M270

The 2463210206 Auto Suspension Rubber Buffer, also known as a bump stop or strut bumper, is a precision-engineered suspension component specifically designed for the Mercedes-Benz X156 (GLA-Class) and W246 (B-Class) models equipped with the M270 engine. This rubber buffer serves as a critical safety device within the vehicle's suspension system, mounted on the piston rod of the front strut assembly. Its primary function is to prevent the suspension from bottoming out during extreme compression events, such as driving through construction zones, over potholes, or when carrying heavy loads. By absorbing and dissipating impact energy, this OE-grade replacement protects the strut or shock absorber from damage, prevents the chassis from making metal-to-metal contact, and maintains proper suspension travel for these compact Mercedes-Benz platforms.

• OEM Direct Fitment: Engineered to replace original Mercedes-Benz part number 2463210206 (also referenced as A2463210206), designed specifically for front axle installation on both left and right sides.

• High-Quality Polyurethane Construction: Manufactured from premium PU (Polyurethane) material. This dense, foam-rubber formulation is designed to be relatively stiff and compact while maintaining durability over multiple impacts, offering superior resistance to cracking, hardening, and compression set compared to conventional rubber alternatives.

• Precision Dimensional Specifications: Features a length of 86mm, width of 63mm, and inner diameter measurements of 18.1mm and 30mm, ensuring exact fitment on the strut piston rod.

• Progressive Damping Design: Some applications utilize the bump stop as a progressive secondary spring, particularly in sport-oriented suspension configurations. This design feature assists in everyday handling by providing progressively increasing resistance during severe compression events.

• Protective Bumper Function: Serves as a cushioning barrier between the suspension components, preventing the chassis from bottoming out against the strut or shock absorber during excessive or unexpected jounces while driving.

• Weather and Age Resistant: Although rubber and polyurethane components naturally age with time and exposure to the elements, this OE-grade buffer is formulated for maximum durability against road salt, moisture, temperature extremes, and UV exposure.

• Prevents Costly Suspension and Chassis Damage: When the rubber buffer is worn, cracked, or missing, severe suspension compression can cause metal-to-metal contact between the chassis and strut assembly. This bottoming-out event can lead to bent components, damaged strut mounts, and chassis deformation. Replacing this proactive buffer protects hundreds of dollars worth of suspension components.

• Restores Proper Suspension Function and Travel: A deteriorated or flattened bump stop no longer provides adequate cushioning during extreme compression events. This replacement restores the factory-specified bump stop height and progressive damping characteristics, ensuring the suspension can safely handle severe impacts without bottoming out.

• Eliminates Clunking and Knocking Noises: If you are experiencing a loud bang, clunk, or knock when going over harsh dips, bumps, or potholes, you may be bottoming out your suspension due to a damaged or torn rubber buffer. This OE-grade replacement eliminates these alarming noises and restores the refined ride quality expected of a Mercedes-Benz.

• Specifically Designed for X156 GLA and W246 B-Class with M270 Engine: Unlike universal bump stops that may not provide the correct progressive damping characteristics or dimensional fitment, this buffer is engineered to the exact specifications of the M270-powered X156 and W246 platforms. The 86mm length and specific inner diameter measurements ensure perfect fitment on the strut piston rod.

• Essential Preventive Maintenance During Strut Replacement: Bump stops naturally age with time and exposure to the elements. Riding on worn bump stops frequently will significantly shorten their lifespan. Industry best practice recommends replacing bump stops every time you replace your struts or shock absorbers, as the labor to access these components is already completed.

• OE-Grade Quality at Competitive Pricing: Available from multiple quality sources including Genuine Mercedes-Benz OE and premium aftermarket manufacturers such as Febi Bilstein. Genuine OE parts are manufactured to original specifications, offering a flawless fit and function, and are meticulously tested to meet Mercedes-Benz standards of quality and performance.

• Progressive Handling Enhancement: For vehicles that utilize the bump stop more frequently to assist normal handling characteristics, a fresh buffer provides progressive resistance that actually enhances everyday driving dynamics. Some sport-oriented suspension designs rely on progressive bump stops as a second spring, making it crucial to keep them in good condition for proper handling.

• Easy, No-Modification Installation: Designed as a direct replacement that slides onto the strut piston rod during assembly. No cutting, trimming, or modifications required, saving labor time for professional mechanics and ensuring proper fitment for experienced DIY installers.

• Visible Wear Indicators: A split, cracked, flattened, or deteriorated bump stop will no longer function correctly. The rubber buffer shows clear visible signs of wear, making inspection straightforward. Replacement is recommended at the first sign of visible deterioration to prevent potential damage from accidental bottoming out.

• Months and Years of Reliable Protection: Manufactured using the finest materials and the latest technology, this buffer is engineered to deliver hassle-free performance and maintain its protective characteristics throughout its service life, ensuring your Mercedes-Benz suspension remains protected against severe impacts.
