Don't risk irreversible engine failure during your track sessions. ACL Race Series crankshaft bearings, featuring trimetal technology, are specifically engineered for demanding F4R engines (Clio R3, RS, and Megane RS).
Offering significantly higher thermal and mechanical resistance than OEM parts, this reference 5M7819H is your insurance for maintaining stable oil pressure and protecting your rotating assembly against the extreme stresses of competitive racing.
The essential barrier against F4R engine failure
Ignoring the condition of your bearings in a Renault Sport engine is an invitation to a inevitable outcome: a spun rod bearing. By keeping standard components during a build or intensive use, you risk losing your entire engine block. ACL Race crankshaft bearings are the ultimate solution to avoid such a mechanical catastrophe.
ACL Race Series Technology: Why Trimetal is vital?
Unlike mass-produced parts, the ACL Race range utilizes a three-layer metal composition (steel, copper-lead, and tin). Without this trimetal design, your engine lacks the embedding capacity required to handle load peaks. These bearings allow for superior heat dissipation and increased tolerance for high RPMs, where factory parts would typically crush or overheat.
Perfect compatibility for the Renault Sport range
Specifically developed for the F4R engine, these Clio R3 type bearings are a perfect fit for:
- Clio 2 RS (172, 182)
- Clio 3 RS (197, 203)
- Megane 2 RS and Megane 3 RS (225, 230, 250, 265, 275)

Frequently Asked Questions about ACL Race 5M7819H Bearings:
Why replace my bearings preventively?
On F4R engines running at high RPM or with increased boost pressure, bearings are critical wear items. Waiting for the first suspicious noise often means the crankshaft is already scored, leading to repair costs multiplied by ten.
What is the difference between H and HX series?
The H series (like ref 5M7819H) adheres to standard clearances, while the HX offers extra oil clearance. For a reliable and durable build, the H series is the trusted standard for the majority of high-quality engine reconstructions.
