1994+ Cummins Single Plane Retrofit Tie Rod End Kit

Fits:

Upgrade an existing Synergy tie rod to the latest single-plane end design without buying a whole new tie rod. The single-plane geometry tightens steering response and kills the "flop" you feel from worn factory or aftermarket joints. Each kit includes one updated passenger-side single-plane tie rod end plus a fresh driver-side boot, so both sides of your tie rod come out refreshed.

Part Numbers: 4167-01, 4168-01, 4169-01
