PERFORMANCE & ENGINE UPGRADES
This Sierra is powered by the legendary 6.6L L5P Duramax Diesel paired to the highly desirable Allison 10-Speed Automatic Transmission, and it has been professionally upgraded with premium performance components throughout.
Key Performance Modifications:
-
WC Fab Stage 3 High-Flow Intake Bundle
-
Custom Gloss Black Powder-Coated Intake Components
-
WC-F100822 Turbo Upgrade
-
VSE Engineering Catch Can System
-
PPE Transmission Cooling Cover
This truck runs extremely strong, has excellent turbo response, smooth power delivery, and drives exactly how a properly built L5P should.
SUSPENSION & HANDLING
Unlike many lifted diesel trucks that ride rough or feel loose on the highway, this Sierra was built correctly using high-quality suspension components that dramatically improve both ride quality and handling.
Suspension Upgrades Include:
-
Kryptonite Upper Control Arms
-
Bilstein 5160 Remote Reservoir Shocks (Front & Rear)
-
WC Fab Rear Track Bars
The ride quality is outstanding both on the highway and around town. Tight steering feel, excellent stability, and an aggressive stance without sacrificing comfort.
WHEELS & TIRES
Aggressive Yet Functional Setup:
-
18-Inch KMC Simulated Beadlock Wheels
-
Graphite Finish
-
Gloss Black Beadlock Ring
-
-
35x12.50R18 Nitto Ridge Grappler Tires
This setup gives the truck the perfect stance while still maintaining excellent drivability and road manners.

EXTERIOR & OVERALL CONDITION
Finished in Onyx Black over Jet Black leather with Kalahari accents, this truck has an incredibly clean and aggressive appearance. The gloss black powder-coated engine components and tasteful wheel/tire setup give it a custom look without going over the top.
This is a true Texas-owned truck its entire life, meaning:
-
Rust-Free
-
Well cared for
-
Clean overall condition inside and out
The interior is exceptionally clean and shows obvious pride of ownership.
