BOSAL 255-557 Rubber Buffer – The Quiet Guardian of Your Exhaust

The Bosal 255‑557 Rubber Buffer, also known as a silencer or exhaust rubber strip, is an essential component for maintaining the integrity and performance of your vehicle’s exhaust system. Designed with precision engineering, this buffer delivers superior vibration damping, noise reduction, and protection against corrosion for a wide range of Chrysler, Dodge, Fiat, and other OEM models.

Key Functionalities

• Vibration Isolation: The high‑density rubber material absorbs engine vibrations that would otherwise travel through the exhaust pipe, reducing fatigue on mounting brackets and hoses.
• Noise Suppression: By interrupting sound wave propagation, the buffer significantly lowers exhaust noise levels, contributing to a quieter cabin experience.
• Corrosion Resistance: The rubber’s chemical stability protects metal components from rust and oxidation caused by exhaust gases.
• Thermal Protection: It acts as an insulator, preventing heat transfer that could damage surrounding parts or affect driver comfort.

Material Composition & Construction

The buffer is crafted from a premium blend of natural and synthetic rubber compounds. This composition ensures flexibility across temperature ranges while maintaining structural integrity under high pressure. The inner surface features a textured coating to enhance grip against the exhaust pipe, preventing slippage during operation.

Compatibility Overview

The Bosal 255‑557 is engineered for a broad spectrum of vehicles, particularly those within the Chrysler and Dodge families. Below are representative models that benefit from this buffer:

• Chrysler Voyager / Grand Voyager / Voyager III (GS)
• Dodge Caravan 3.3 (1995‑2001)
• Fiat models that share the same exhaust architecture
• Other OEMs with matching mounting brackets and pipe diameters

When selecting a buffer, verify that the mounting bracket size matches the BOSAL 255‑557 specifications. The buffer typically comes in a single piece but is often sold as a pair (2PCS) for symmetrical exhaust systems.

Installation Guide

1. Preparation: Ensure the vehicle’s engine and exhaust system are cool to avoid burns. Clean the mounting area of any debris or old gasket material.
2. Positioning: Slide the buffer onto the exhaust pipe, aligning it with the designated mounting bracket. The textured side should face the pipe for optimal grip.
3. Securing: Fasten the mounting bracket over the buffer using the supplied bolts or clips. Tighten to the manufacturer’s torque specifications to avoid overtightening.
4. Verification: After installation, start the engine and listen for any rattling or excessive noise. Adjust if necessary.

Maintenance Tips

• Inspect the buffer annually for signs of cracking, hardening, or wear.
• Reapply a high‑temperature silicone sealant around the mounting area to maintain a tight seal and prevent leaks.
• Avoid exposure to extreme chemicals that could degrade rubber integrity.

Benefits Over Conventional Metal Mounts

Traditional metal exhaust brackets transmit vibrations directly to the vehicle chassis, leading to accelerated wear of suspension components. The Bosal 255‑557 Rubber Buffer mitigates this issue by acting as a flexible intermediary. This not only prolongs the life of the exhaust system but also enhances overall ride comfort.
