I purchased a 5.3L LS engine swap package from this company, and the experience was excellent from start to finish. The engine arrived exactly as described, very clean, and in great condition.
What really stood out was the professional installation support — the mechanic ensured everything was installed correctly and running smoothly the same day. The engine performs perfectly, with strong power and no issues at all.
Great communication, fast delivery, and solid warranty backing. I highly recommend them to anyone looking for a reliable LS engine or swap setup.

Wow! This 5.3L rebuild is built like a tank. Everything feels solid—pistons, heads, seals—everything was carefully assembled. My truck now has excellent highway power and plenty of torque for towing. After a week of use, I can confidently say this is one of the best rebuilt engines I’ve owned. Excellent choice if you plan to keep your truck for years.

“I installed the 5.3L LM7/L59 Rebuilt Truck Engine in my ’04 Silverado and couldn’t be happier. Right out of the box the engine looked clean and professionally assembled. After install, it fired up smoothly and runs like a dream—quiet, strong, and responsive. Perfect blend of power and reliability. Finally feels like I have my truck back! Highly recommended if you want a quality rebuilt engine without breaking the bank.”

Excellent engine overall. The 5.3L LM7/L59 rebuilt engine restored my truck’s performance like new. Strong acceleration, smooth idle, and lots of torque for hauling. The only slight downside was the lack of detailed instructions—but my mechanic had no problem. I’d buy it again in a heartbeat and recommend it to others needing an affordable, high-quality rebuilt engine.

This rebuilt 5.3L LM7/L59 engine has been a great upgrade for my daily driver. Installation went pretty straightforward, and it’s noticeably more responsive than my old engine. I’ve done about 3,000 miles so far with no issues. The only reason I’m giving 4 stars instead of 5 is because I waited longer than expected for delivery—but the performance makes up for it. Great value for the money!
