3Racing Sakura D4 Rear Suspension Mount SAK-U407_V2/BK Race Tuned 7075  [SAK-U407_V2/BK]

Stiffen the rear end for cleaner lines

The 3Racing Sakura D4 Rear Suspension Mount SAK-U407_V2/BK uses 7075 aluminum construction to reduce unwanted flex and help the chassis hold its geometry. It is tailored for Sakura D4 layouts so modellers can gain more predictable mid corner behaviour and improved straight line stability.

Why 7075 is a popular choice

7075 alloy offers a durable, lightweight option for upgrade parts. This mount resists deformation under load while keeping unsprung mass low, which helps maintain steering feel and response over rough sections.

Practical gains on street and track

Fitting the 3Racing 7075 mount gives a firmer attachment for the suspension pivot, which reduces play and keeps alignment consistent. The result is steadier acceleration, cleaner turn in, and better overall control when adjusting setup for different surfaces.
