Type 3030 2 Pack Air Brake Chamber Welded Clevis 2.5in Stroke

In this review the Torque Type 3030 2 pack air brake chamber is evaluated for drivers and fleet mechanics who need a direct replacement chamber with reliable stopping power. The bottom line: this pair is aimed at heavy truck and trailer owners who want a hard-wearing, industry-compatible replacement that mirrors OEM fit and function. The review focuses on build quality, key dimensions like the 2.5in stroke and 9in spring housing length, and the practical benefits of the double O-ring sealing and powder-coated service housing.

Key Features

• Type and Fit: The 3030 30/30 configuration is a direct replacement for K129605, K067114 and common GC3030CW variants, so it fits many semi truck and trailer brake setups without modification.
• Stroke and Actuation: The 2.5in available stroke and 1in pushrod length deliver predictable actuation and compatibility with standard clevis setups.
• Durable Construction: A rugged 9 gauge steel service housing with advanced powder coating resists corrosion and helps the units last in harsh road environments.
• Sealing and Bearings: The double O-ring centerseal and plastic bearings provide positive sealing and smoother internal movement for longer life under repeated use.
• Power Spring Technology: Improved spring design aims to provide consistent braking force and reliable return action across heavy-duty cycles.
• Warranty: A 1-year unlimited mile warranty offers a clear replacement path if the unit fails within the warranty period.

Who It's For

This product is best for professional technicians, owner-operators, and fleet managers who maintain semi trucks or trailers and need a dependable replacement chamber that matches common OEM part references. Its welded clevis and measured dimensions make it suitable for vehicles that require a TYPE 3030 30/30 configuration and a 2.5in stroke.

It is less appropriate for operators who need nonstandard stroke lengths, custom pushrod lengths beyond 1in, or those seeking chambers with different mounting styles. Buyers who require extended factory certifications should verify compatibility with their specific vehicle model before purchasing.
