Renault Twingo R2 Upper Valve Spring Retainer

Why failing to replace your Renault Sport valve retainers puts your engine at risk?

In the world of engine tuning and motorsport, every component is subjected to extreme thermal and mechanical stress. Ignoring the wear on your valve spring retainers means accepting the risk of valve float or a fatal engine breakdown for your Renault Sport block.

A precision-engineered part from the Renault Competition catalog

This upper spring retainer (reference 7711167577) is not just a simple spare part. It is a vital component to maintain the exact tension of your valve springs on the high-performance engines of the Twingo R2. Without a perfectly calibrated retainer, you lose lift precision, leading to an immediate power drop and instability in the engine cycle.

Strict technical compatibility: Twingo R2 195 and 205 hp

To ensure the integrity of your performance vehicle, it is crucial to follow the manufacturer's recommendations:

• Twingo R2 195 hp: Required fitment for both intake and exhaust valves.
• Twingo R2 205 hp: Specific fitment for exhaust valves only.

Frequently Asked Questions about reference 7711167577

When should you replace your spring retainers?

During every major cylinder head overhaul or as soon as you notice spring fatigue. A worn or deformed retainer no longer holds the spring in its optimal axis, which can lead to valve stem breakage.

Can I use a standard part instead of the Renault Sport part?

Using non-homologated parts instead of Renault Sport components on a Twingo R2 compromises your safety and engine longevity. Reference 7711167577 is manufactured with specific alloys to withstand the high rotation speeds typical of rally stages.
