How do I install 4G63 Rocker Retainers?Updated 18 minutes ago

Our 4G63 clips fit over your existing rocker arms, with no machining or modifications.

Key steps

1. Get access to the rocker arms following your workshop manual.
2. Fit a clip to each rocker arm.
3. Check clearance between each clip and its lash adjuster through the full range of rocker movement. The clip shouldn't rub or bind in normal operation. This matters most on cast rocker (Evo 1 to 3) engines.
4. Reassemble, making sure nothing has dropped into the head.

Watch it done

There's an install video on the Evo 1 to 3 product page.

Something doesn't look right?

If a clip contacts the lash adjuster or doesn't sit properly on the rocker, stop before running the engine. Email [email protected] with photos and your engine details.
