Important: This bracket set is specifically designed for vehicles originally equipped with 22R/22RE 4-cylinder engines. On 1986-1995 4x4 Truck and 4Runner applications, the upper control arm frame mount must remain in place. Requires OEM-style engine block brackets and rubber mounts from 1991-1995 3VZ-FE applications (not included). Professional welding skills required for proper installation.

Installation & Maintenance

Installation Difficulty: Advanced
Tools Required: MIG welder, angle grinder, cut-off wheel, measuring tape, level, socket set, torque wrench, safety equipment
Professional Installation: Strongly recommended - requires expert welding and precise frame alignment

Installation Tips:

• Completely remove original 22R/22RE frame mounts before installing new brackets
• Test-fit all components with engine in position before final welding
• Verify proper engine alignment and clearances before permanent installation
• Apply quality primer and paint to bare steel brackets for corrosion protection

 

Frequently Asked Questions

Q: What's included in the package?
A: This set includes left and right frame-side mounting brackets with comprehensive installation instructions. Engine block-side brackets and rubber mounts from 1991-1995 3VZ-FE applications must be sourced separately.

Q: Can I use these brackets with 2WD frames?
A: The 1979-1985 version is not specifically designed for 2WD applications but will likely work well. The 1986-1995 version requires the upper control arm frame mount to be in place, which is typically only present on 4x4 frames.

Q: Do I need to modify my frame beyond welding these brackets?
A: No frame modifications beyond removing the original 4-cylinder mounts and welding these brackets in place are required. However, proper alignment and measurement are critical for correct engine positioning.

Why Choose Professional Frame Brackets for Your 3.4L Swap

Foundation of a Successful Conversion: The 3.4L 5VZ-FE swap represents one of the most popular and reliable engine conversions in the Toyota enthusiast community. However, the success of any engine swap begins with proper mounting. These precision-engineered frame brackets provide the critical foundation for reliable engine positioning and long-term durability.

Unlike fabricated or improvised mounting solutions, these laser-cut steel brackets ensure proper alignment and load distribution across the frame rails. The engineering accounts for the significant differences between 4-cylinder and V6 mounting geometry, providing the exact positioning needed for optimal driveline angles and component clearances.

The design leverages proven OEM mounting components from 1991-1995 3VZ-FE applications, combining the benefits of factory-engineered rubber mounts and brackets with purpose-built frame-side hardware. This hybrid approach delivers the reliability of OEM components with the adaptability required for successful engine conversions.

Professional welders and experienced fabricators appreciate the precision fit and comprehensive instructions that eliminate guesswork and reduce installation time. The heavy-duty steel construction provides peace of mind that your investment in a 3.4L conversion is supported by mounting hardware engineered to handle the increased power and torque of the V6 platform.

Don't compromise your 3.4L swap with inadequate mounting solutions. Invest in engineered frame brackets that provide the foundation for a reliable, professional-quality engine conversion that will deliver years of enhanced performance and capability.
