TL4 Gearbox Snap Ring Set 1.5-1.9 mm | Renault Clio 3 RS

The risks of improper shaft end play in a TL4 gearbox: what your Clio 3 RS stands to lose

When opening or rebuilding a TL4 6-speed manual gearbox on a Renault Clio 3 RS, re-using a worn snap ring or an incorrect shim size leads to destructive consequences. Imprecise axial clearance lets the input or output shaft shift under high-rpm loads and aggressive downshifts. This lateral movement causes popping gears, vague engagement, crunching during gear shifts, and accelerated wear on synchronizers.

Leaving a transmission shaft floating also exposes the gear train to abnormal mechanical stress, risking broken gear teeth or seized bearings during hard driving. By using this genuine Renault retaining snap ring kit, you eliminate unwanted shaft play: you protect your shift quality, avoid costly internal gearbox failures, and restore factory-smooth gear changes.

Manufactured to strict OE specifications, these precise retaining circlips and shims deliver the thermal hardness and accurate tolerances required to handle high torque output.

Adjusted thickness range from 1.5 mm to 1.9 mm for custom gearbox rebuilds

This complete set of retaining snap rings for TL4 gearboxes contains multiple thickness increments (from 1.5 mm to 1.9 mm) essential for measuring axial end play and selecting the exact retaining shim recommended by factory service manuals. It is the indispensable shimming solution for heavy transmission maintenance and gear set customization on your sports vehicle.

Frequently Asked Questions about TL4 Gearbox Snap Rings (FAQ)

Why is measuring axial clearance necessary before choosing the snap ring?
Gearbox casings and bearing stacks have minor manufacturing tolerances. Measuring clearance with a dial indicator or feeler gauge allows you to select the precise ring thickness (between 1.5 mm and 1.9 mm) that eliminates excess play according to factory specifications.

Can old circlips be reused when changing bearings?
No, a removed snap ring undergoes elastic deformation and loses clamping force. Furthermore, replacing bearings changes the required shim stack height, making a new snap ring of the correct thickness mandatory.
