Powerflex Gearbox Mount Bushing PFF60-1421 | Renault Clio 4 RS

The drawbacks of a worn factory gearbox mount: what your Clio 4 RS stands to lose

On a performance vehicle equipped with a dual-clutch EDC transmission, firm engine and gearbox mounting is essential. Retaining a soft, aged, or cracked OEM rubber gearbox bushing causes excessive engine-gearbox rocking during heavy acceleration and aggressive downshifts. This severe engine pitch leads to wheel hop, traction loss, hesitant gear changes, and premature wear on exhaust flex pipes and driveshafts.

Standard rubber mounts soften rapidly under heat cycles and spirited driving conditions. Without firm powertrain stabilization, front-end steering precision and throttle response suffer. Installing the Powerflex polyurethane gearbox mount bushing (reference PFF60-1421) stiffens the assembly without replacing the entire OEM metal bracket, eliminating mechanical sloppiness and maximizing chassis feedback.

Engineered by Powerflex, the global leader in polyurethane suspension bushings, the PFF60-1421 offers superior resistance to oil, environmental degradation, and high torque loads.

High-performance polyurethane, enhanced traction, and EDC responsiveness

Thanks to the physical properties of polyurethane, this insert significantly reduces gearbox mount deflection while absorbing destructive vibrations. It is a key upgrade for preventive drivetrain maintenance or chassis customization on your performance vehicle for both fast road and track use.

Frequently Asked Questions about Powerflex Bushing PFF60-1421 (FAQ)

Is modification required to install this insert into the factory gearbox mount?
No, the Powerflex PFF60-1421 bushing fits directly into the voids of the original factory bracket or replaces the worn voiding without altering chassis mountings.

Does a polyurethane bushing introduce severe cabin vibration?
A slight increase in feedback may be felt at idle, but it remains minimal compared to the massive gains in traction, shifting accuracy, and engine stability.
