Author : Olive Sophia | Published On : 27 Apr 2026
If you have been searching for cheap Toyota Tundra engines without wanting to sacrifice quality, you have likely come across Moon Auto Parts. As one of the more talked-about online engine suppliers in the used and remanufactured auto parts space, Moon Auto Parts has built a growing reputation for offering competitive pricing with a level of reliability that keeps customers coming back. I recently purchased a replacement 5.7L V8 engine (3UR-FE) for my 2007 Toyota Tundra CrewMax and put Moon Auto Parts to the test. Here is my full, unfiltered review.
The Problem: 2007 Toyota Tundra 5.7L V8 Engine Failure at 178,000 Miles
My 2007 Toyota Tundra had served me faithfully for years, but after 178,000 miles, the inevitable happened: excessive oil consumption, low compression in two cylinders, and a mechanic's diagnosis that pointed to piston ring failure. A full engine rebuild quote came in at $4,200. An OEM replacement from the dealership was quoted at over $6,800. I needed another option and fast.
Finding Moon Auto Parts
After researching online for cheap Toyota Tundra engines that had verifiable reviews and documented history, I landed on Moon Auto Parts. Their website was professional and easy to navigate, with engine listings clearly organized by year, make, model, and engine code. The 2007 Tundra 5.7L (3UR-FE) listing showed available units with mileage ranging from 68,000 to 95,000 miles.
The Ordering Experience
I called Moon Auto Parts' customer service line before committing. The representative was knowledgeable they quickly confirmed compatibility with my 2007 Tundra 4WD CrewMax and clarified what was included: a long-block engine (block, heads, valvetrain complete) with accessories. She also confirmed the unit had been compression-tested in-house. The quoted price for a 72,000-mile unit was $1,690 — significantly below competitors I had checked. Shipping via freight to my mechanic's shop was $185.
Engine Arrival: Packaging and Condition
The engine arrived in nine business days on a reinforced pallet, shrink-wrapped and strapped. There were no signs of transit damage. My mechanic noted the engine looked clean no visible oil sludge on the valve covers or in the oil fill neck, no signs of coolant contamination. He was cautiously impressed given the price point.
Post-Installation Performance
It has now been four months and approximately 6,200 miles since installation. The 2007 Tundra 5.7L V8 from Moon Auto Parts runs exactly as it should strong acceleration, no misfires, no oil burning, and rock-solid idle. Fuel economy has returned to expected levels (averaging 14.5 MPG mixed driving), and my mechanic has seen no signs of leaks or abnormal wear at the 3,000-mile check.
Warranty and Customer Service
Moon Auto Parts provided a 4 year 40k miles warranty on the engine with a clear, straightforward process for claims. I had one follow-up question about a breather hose fitting post-installation and received a helpful, quick response from their support team. They also confirmed the warranty is backed by documentation, not just a verbal promise.
Overall Verdict
Moon Auto Parts earns a strong recommendation for anyone seeking cheap Toyota Tundra engines without cutting corners on quality. For my 2007 Tundra 5.7L V8, they delivered a documented, tested, clean engine at roughly 25% of the dealer replacement cost. The experience from order to installation was smooth, transparent, and professional.
