⚙️ Important Note
The transmission currently needs a rebuild, and $1,500 has been discounted from the asking price to reflect that. The rest of the truck and drivetrain are in excellent condition — this is a strong, well-built street truck that just needs the trans refreshed to be 100% show-ready.
💪 Why This Truck Stands Out
This Silverado isn’t just built — it’s refined. After initial construction at G&G Performance, the engine was dialed in and perfected by Danny’s Performance Lab in Seagoville — a shop known for precision, reliability, and high-quality GM & Ford performance builds.
