If your Holden is starting to wander under brakes or feel vague through the steering wheel, tired lower control arm bushes are often the root cause. The Lower Control Arm Inner Bush is designed to suit Holden HZ and WB models, restoring proper suspension geometry and the confident front-end feel these vehicles were built with. This construction allows the front lower control arm (wishbone) to pivot smoothly through its suspension travel while maintaining accurate wheel alignment under load.
Premium Silentbloc Construction: Incorporates an internal metal crush sleeve chemically bonded to a high-density vulcanised rubber core and outer shell, ensuring strength, durability and correct suspension articulation.
Radial Tuned Suspension Damping: Calibrated to match original RTS (Radial Tuned Suspension) geometric parameters, delivering optimal compliance for cornering side-loads while preventing excessive harshness from transferring into the chassis and steering column.
Anti-Torsional Slip Bond Technology: The bonded rubber-to-metal design prevents the bush from spinning, deforming or tearing under heavy articulation, ensuring long-term reliability and consistent suspension behaviour.
Quantity Supplied: 1 x Individual Bushing (A complete front suspension overhaul requires 2 inner bushes per side — 4 total across the front axle.)
Whether you’re refreshing a daily driver or tightening up a restoration project, the Lower Control Arm Inner Bush helps bring back precise steering response, stable braking performance and the balanced ride quality your HZ or WB Holden was designed to deliver.
