A-Premium Engine and Transmission Mount Kit for 2003–2008 Toyota Corolla/Matrix & Pontiac Vibe 1.8L — Set of 4, OE-fit Durable

A-Premium's four-piece engine and transmission mount kit replaces worn mounts on 2003–2008 Toyota Corolla, Matrix and Pontiac Vibe models with the 1.8L automatic transmission.

If your vehicle shows vibration, engine movement, or unusual noise during acceleration and shifting, tired motor mounts are often the cause. This kit includes the front, front-right, rear engine mounts plus the transmission mount, built to align with original equipment dimensions and engineered for durability. Materials and production are tested to meet or exceed factory standards so the replacement fits securely and restores proper engine positioning.

Which vehicles and engines does this kit fit?

This A-Premium kit is made for 1.8L inline‑4 models with automatic transmissions from the 2003–2008 model years of Toyota Corolla, Toyota Matrix and the Pontiac Vibe. Confirm compatibility by matching your vehicle year, engine size and transmission type before purchasing.

What does the kit include and why replace all four mounts at once?

• One installation event addresses all major mounting points for consistent engine alignment
• Prevents uneven stress and vibration that can harm driveline components

A-Premium designs these mounts to match OE geometry and load capacity while using durable elastomers and metal components. Every mount goes through dimensional checks and stress testing to help ensure the replacement performs like the original part.

• Manufactured to meet or exceed original equipment specifications
• Materials chosen for resistance to oil, heat, and road vibration
• Reference numbers included for cross-checking: e.g., 123050D023, 88973356, 123710D110 and related OEM codes

What guarantee and support does A-Premium provide?

Who is this for: This kit is aimed at drivers and DIY mechanics who own a 2003–2008 Toyota Corolla, Matrix or Pontiac Vibe with the 1.8L automatic drivetrain and need to restore stable engine mounting.
