Rear Shock Tower Optimised for Setup Consistency

The 3Racing Cactus 2WD Aluminum Rear Shock Tower CAC-308 is a purpose-built upgrade for the Cactus 2WD mid-motor configuration. It provides a more rigid rear shock mounting platform to reduce chassis flex and maintain repeatable geometry during high load transitions.

Material and Impact on Handling

Aluminium offers a firmer mounting surface compared with stock materials, which can improve tyre contact consistency and feedback. The CAC-308 helps stabilise the rear end so suspension adjustments yield more predictable changes on track.

Installation and Tuning Considerations

Engineered to match the Cactus 2WD mounting layout, the tower installs with standard hardware and allows technicians to focus on shock valving, spring choice and anti-roll adjustments. Expect to refine rear damping to match the increased mounting stiffness.

How does the CAC-308 affect tuning choices?

A stiffer rear mount typically reduces unwanted compliance, making shock and spring changes more effective. Start with small adjustments to damping and spring rate when moving from the stock tower.

Is the fit precise enough for competitive use?

The CAC-308 is produced to the Cactus 2WD mid-motor mounting spec to ensure accurate alignment. A precise fit reduces setup variance between runs, which is desirable for race preparation.

Any recommended hardware or prep?

Use correct length machine screws and consider medium strength thread locker for metal-to-metal joints. Verify screw torque after initial runs and recheck after heavy impacts.
