F250/F350 Super Duty 2017-2022 Ford 4wd (w/8" lift) - Transfer Case Indexing Ring Kit by BDS Suspension

Protect your front driveline and eliminate vibration on your lifted 2017–2022 Ford F-250 or F-350 Super Duty 4WD with the BDS Transfer Case Indexing Ring Kit (SKU: 123615). When running an 8-inch suspension lift or taller, indexing the transfer case is required to allow the factory front driveshaft to reconnect properly and operate without binding or vibration.

The indexing ring is drilled for a fixed 8-inch lift height and features optimal spline engagement to maintain proper alignment between the transmission and transfer case.

To ensure proper fitment after indexing, BDS includes a high-clearance transmission crossmember that provides the necessary clearance and prevents interference with surrounding components. Built from heavy-duty steel, this kit delivers the strength and durability required for tall lift applications and long-term reliability.
