Rear ARB Drop Links – Balanced Handling and Rear Suspension Control
Rear ARB drop links are vital suspension components that connect the rear anti roll bar (sway bar) to the suspension, allowing it to operate correctly during cornering and load changes. By transmitting suspension movement to the anti roll bar, rear drop links help control body roll, maintain chassis balance and improve rear-end stability.
At Design911, we offer OE replacement and performance rear ARB drop links from trusted suspension brands. Whether you’re replacing worn components or upgrading as part of a handling-focused suspension setup, quality rear drop links are essential for predictable, confidence-inspiring driving.
What Do Rear ARB Drop Links Do?
Rear ARB drop links act as the linkage between
the rear suspension and the anti roll bar, ensuring the bar can resist body
roll effectively. Their key functions include:
- Transferring suspension movement to the anti roll bar
- Improving rear-end stability during cornering
- Helping balance front and rear handling characteristics
- Supporting consistent traction and tyre contact
Worn or damaged rear drop links can reduce the effectiveness of the anti roll bar and negatively impact handling balance.
Why Upgrade or Replace Rear ARB Drop Links?
- Replacing or upgrading rear ARB drop links provides:
- Restored anti roll bar effectiveness
- Reduced knocking or clunking noises from worn joints
- Improved handling balance and stability
- Better compatibility with upgraded or adjustable anti roll bars
Performance rear drop links may feature uprated joints, stronger materials or adjustable lengths, making them ideal for lowered vehicles or fast-road and track-focused suspension setups.
When Should You Replace Rear ARB Drop Links?
Rear ARB drop links should be replaced when:
- Knocking or rattling noises are present from the rear suspension
- Ball joints or bushes show play or wear
- Installing new anti roll bars or lowering springs
- Carrying out a suspension refresh or alignment
- Rear handling feels inconsistent or unstable
Replacing worn rear drop links ensures the anti roll bar works as intended and helps maintain predictable rear-end behaviour.
At Design911, our rear ARB drop links meet OE or performance standards for fitment, durability and handling performance.
