Transfer Case Indexing Ring | 6-Bolt | Ram 2500 (14-18) and 3500 (13-18) 4WD | Diesel

Built for Ram 2500 and 3500 diesel owners who lift their truck and need to recalibrate the transfer case — when you raise your truck, the driveshaft angles change and the transfer case needs re-indexing to keep power delivery smooth and protect drivetrain geometry. This 6-bolt indexing ring corrects that geometry on 4WD models.

Installed and serviced at Road Runner Wheels & Tires. Most kits go in the same day. Call (678) 400-6467 to schedule.

Important notes

• Fits Ram 2500 4WD (2014–2018) and Ram 3500 4WD (2013–2018) diesel models with 6-bolt transfer case flanges.
• Transfer case re-indexing is required when lifting your truck to maintain correct driveshaft angle and prevent premature wear on U-joints and transfer case internals.
• This ring is a critical component of any BDS lift kit for these trucks — do not attempt a lift without it if your driveshaft geometry requires correction.
