Lease for as low as $/week
A replacement yoke & universal joint kit designed for use with IAG transfer gear sets (IAG‑DRV‑1000 and DRV‑1010). It includes everything you need to replace wear-prone drivetrain components as part of routine maintenance or after heavy use.
🔧 Purpose & Role
-
Wear item replacement: The yoke and U‑joint on the transfer gear set experience high stress—especially under aggressive driving or drag racing—so this kit is essential to restore optimal drivetrain function.
-
Maintains drivetrain strength: Keeping these parts fresh ensures that the integrity of your drivetrain system remains intact, avoiding potential failures down the line.
🧩 Included Components
-
Heavy‑duty driveshaft yoke compatible with IAG DRV‑1000/1010 gear sets
-
Matched universal joint assembly, complete with snap rings
-
Overall unit constructed from high-quality steel for durability
🚗 Vehicle Fitment

-
Addresses fitment across both “1:1” (04‑05) and “1.1:1” (06‑21) transfer gear sets when used with the correct IAG kit
🏁 Maintenance Recommendations
-
Regular inspection: Inspect yoke and U‑joint health during gear replacement or after intense launches.
-
Service interval: Replace whenever play is noticed, noise arises, or during a full rebuild—especially on performance-built cars
-
OEM match: Specifically replaces the yoke kit included with IAG transfer gear sets—ensuring proper fit and performance.
✅ Key Benefits
-

🧠 Final Take
If you're running IAG's performance transfer gears (DRV‑1000/1010) and hitting the track, drifting, or hauling serious torque, this kit is essential maintenance. Skipping it can lead to premature wear or U‑joint failure. Swapping out the yoke & U‑joint is a wise investment to safeguard your gearbox and drivetrain system.
