Gear Hub Slider 1st/2nd + Synchronizers - Renault Clio 3 RS TL4

The cost of inaction: Why ignore your TL4 gearbox issues?

A stiff gear change or grinding between 1st and 2nd gear is never a good sign on a Clio 3 RS. By continuing to drive with a worn synchronizer or a damaged gear hub slider, you risk irreparable damage to the gear teeth of your TL4 transmission. Eventually, you may face a complete inability to engage gears, leading to forced vehicle immobilization and much higher repair costs than a standard rebuild kit.

A complete Genuine Renault kit for unfailing reliability

Unlike aftermarket parts of uncertain quality, this Genuine Renault kit guarantees compliance with manufacturer tolerances. The TL4 gearbox is precise but demanding; using official components allows you to regain the firm shifting feel and speed characteristic of Renault Sport models. This kit includes:

• The 1st/2nd gear hub slider (synchro hub).
• The 3 synchronizer rings for 1st gear.
• The 3 synchronizer rings for 2nd gear.
• The 3 synchronizer keys (spring clips).

Frequently Asked Questions on Clio 3 RS Gearbox Rebuilds

Why does my gearbox crunch at high RPM?

Under the stresses of performance driving, the synchro rings wear down and can no longer equalize the speed of the gears. Replacement with this original kit is the only lasting method to stop this phenomenon.

Is it necessary to change the hub slider along with the synchros?

Yes, because the teeth of the hub slider wear down simultaneously. Changing only the rings without the slider hub exposes the new components to premature wear.
