Rebuilding a ZF 8HP or Chrysler 845RE? Don't risk your rebuild with generic tools. The ZF 8-Speed transmission relies on extremely precise bushing clearances to maintain pressure. Driving these bushings in crooked or damaging the soft aluminum housing with metal tools can lead to immediate failure, P0731 codes, or burnt clutches.
This Master Bushing Driver Kit is designed specifically to install the full set of bushings found in the popular Sonnax 35030-01K kit (and OEM equivalents). Each driver is sized to perfectly center the bushing without marring the bore.
Why use these tools?
Impact Resistant Material: Manufactured from a high-strength industrial polymer that is tough enough to be driven with a hammer but softer than aluminum—meaning you cannot score or gouge the transmission housing if you slip.
Precision Fit: Each driver is engineered with a pilot to hold the bushing square during installation, preventing the "bushing tilt" that causes immediate wear.
Comprehensive Coverage: This kit covers the critical failure points in the 8HP rotating assembly.
