YOUR BUILD JOURNEY
From Order to Production
Your order is not sent directly into production. Every custom build goes through RVRN engineering review before manufacturing begins.
Order Confirmed
Your custom specifications are received.
Engineering Verification
Fitment, clearance, and finish details are reviewed.
Production Begins
Manufacturing starts only after your build is approved.
Production Updates
Follow your wheel build through machining and final inspection.
Order & Fitment
Every RVRN wheel is a custom forged product, engineered and built to your exact vehicle specification. Production does not begin until your build is reviewed and confirmed by our engineering team.
Because each set is made to order, final specifications are confirmed during the engineering review. Estimated lead times are indications only and may vary with finish and component selection. Pricing shown is per wheel; your complete set is quoted at checkout.

About This Build
Precision Multi-Spoke Architecture for GMC Trucks
The RV-MG121 is engineered as a premium GMC wheels solution, featuring a refined multi-spoke forged design that balances visual density with structural clarity. Each spoke is shaped with multi-dimensional surfacing, creating a layered, OEM+ aesthetic that avoids flat or “plastic” visual effects.
Designed specifically for modern truck applications, this wheel delivers a strong, technical presence through its black with polished finish, highlighting the contrast between performance engineering and premium detailing. The spoke layout enhances brake visibility while maintaining a solid, professional-grade stance expected from high-end custom forged multi spoke wheels for GMC Sierra and trucks.
Forged Strength Meets Lightweight Performance
Manufactured from aerospace-grade 6061-T6 aluminum, the RV-MG121 is built using advanced forging techniques to achieve exceptional structural integrity and weight optimization.
This is not just a styling upgrade—it is a performance-driven wheel solution:
- Heavy-Duty Load Rated Structure engineered for towing, hauling, and real-world truck demands
- Optimized weight reduction to improve handling, acceleration, and braking response
- FEA-validated spoke geometry ensuring even load distribution and long-term durability
- Enhanced brake clearance through intelligent spoke spacing and concavity design
The result is a set of lightweight performance wheels for GMC trucks that deliver both strength and responsiveness without compromise.
Engineered for GMC, RAM & Cadillac Truck Platforms
The RV-MG121 is commonly configured for a wide range of full-size truck applications, including platforms from GMC, RAM, and Cadillac.
Typical fitment applications include:
- GMC Sierra 1500 / 2500 / 3500
- RAM 1500 / 2500 / 3500
- Cadillac Escalade (truck-based platform)
Each wheel set is fully customized to your vehicle’s specifications, including brake system, suspension setup, and desired stance. Whether you're building a street-focused truck or a heavy-duty work setup, the RV-MG121 delivers precise fitment, optimized load capacity, and a commanding visual upgrade.
This flexibility makes it an ideal choice for those seeking custom truck wheels for RAM trucks, as well as performance wheels for Cadillac and GMC platforms, without limiting the application to a single vehicle.
