2.3mm Crankshaft Thrust Washer - Renault Clio RS & Megane RS

Why failing to replace your crankshaft thrust washers exposes your engine to total failure?

When rebuilding a Renault Sport engine, overlooking the replacement of thrust washers is a costly mistake. Without a new genuine Renault crankshaft thrust washer pair, you risk premature wear of the engine block and crankshaft due to excessive axial play. If not corrected by a strict 2.3 mm thickness, this clearance leads to destructive vibrations and can result in total engine failure at high RPMs.

Wide Compatibility for Renault Sport and Racing Ranges

These critical components are engineered for the most demanding setups. Whether you are preparing a Clio 2 RS Group N, a Clio 2 X65 Cup, or a Clio 3 RS X85 Cup, the fitment must be perfect. These washers are also compatible with Clio R3, Megane 2 RS, Megane 3 RS, and rally versions like the Megane N4.

Frequently Asked Questions about 2.3 mm Thrust Bearings

Why choose the 2.3 thickness genuine Renault part?

Choosing a genuine Renault part is a safeguard for your engine customization. The 2.3 mm thickness is the required standard to keep the crankshaft in perfect alignment. Using lower-quality aftermarket parts means accepting a risk of internal friction that could destroy your engine block in just a few miles.

Is it necessary to change thrust washers every time the engine is opened?

Absolutely. Crankshaft end play shims endure constant friction stress. Failing to replace them means risking the crankshaft "machining" directly into your engine block main caps. It is a minimal investment to save a Clio Williams or Megane RS engine.
