Precision Rear Lower Arm for Competitive Setup

The 3Racing SAK-D4805 Aluminum Rear Lower Suspension is engineered to replace the Sakura D4 rear lower arm with a more rigid aluminium component. This upgrade reduces compliance in the rear subframe and provides a consistent platform for tuning damping and roll behaviour.

Material and Construction Benefits

The aluminium design delivers predictable flex characteristics and improved resistance to impact fatigue compared with molded plastic. That consistency makes setup adjustments more repeatable for drivers chasing marginal gains in lap times.

Fitment and Tuning Notes

Manufactured to align with Sakura D4 mounting geometry, the SAK-D4805 installs without modification and supports standard linkage positions. Expect a firmer rear response; adjust shock rates and anti roll settings to refine handling for your chosen tyre and surface combination.

Does this arm alter roll centre or hinge pin height?

The SAK-D4805 maintains the factory hinge pin location, so roll centre changes are minimal. Any perceived difference is typically due to reduced arm flex rather than altered geometry.

What setup changes are recommended after fitting?

Start with your baseline setup and expect to fine tune rear damping and anti roll adjustments. Reduced arm compliance often benefits from slightly softer rear damping to recover rotation.

Is machining tolerancing consistent across parts?

Production tolerances are controlled for repeatable fitment, but inspect each arm for burrs or finish issues and deburr mounting holes before installation if required.
