Product Details

The fatal risk of unsuitable rod bearings on the Twingo RS

The 1.6 16V engine of the Twingo 2 RS is a precision-engineered machine that demands flawless lubrication. Ignoring bearing replacement during an overhaul or using approximate references exposes you to a "spun bearing" failure. Without this genuine Renault rod bearing shell, you risk irreversible damage to the crankshaft and a hole in the engine block. The loss here is total: a complete engine replacement instead of controlled preventive maintenance.

The crucial importance of the OEM Yellow Mark

The yellow mark defines a specific thickness class essential for maintaining the correct clearance between the connecting rod and the crankpin. In competition, on a Twingo R1 or a 160hp Twingo R2, thermal and mechanical stresses leave no room for error. Only the Renault Sport part ensures:

Optimal heat dissipation to prevent seizure.
An anti-friction layer compliant with the original manufacturer specifications.
Perfect durability against peak combustion pressures.

Frequently Asked Questions about Twingo 2 RS Bearings

Why choose genuine Renault over an aftermarket brand?

Renault Sport engines have very strict metrology requirements. A difference of just a few microns can cause a drop in oil pressure when hot. The OEM bearing is the only one to guarantee the longevity of your bottom end under intensive use.

Should I change the rod bolts at the same time?

Absolutely. Rod bolts undergo "stretch" during installation. To ensure that your yellow mark bearing shell stays perfectly in place, replacing the bolts is mandatory. You can find them in our complementary items at the bottom of this page.
