Dinan 21-26 BMW 430i/M440i (G22/G23/G26) Adjustable Front & Rear Sway Bar Set - 28mm & 19mm

Every Dinan tuned anti-roll bar on the other hand is built and tuned specifically for each targeted BMW chassis to provide a more responsive and crisp experience. By reducing the amount of body roll your BMW is kept much closer to level than stock (while still allowing just enough body roll) to improve mechanical grip. This improvement gives the driver a much more planted and confident feeling in every corner making it a must-have upgrade for back road and track enthusiasts alike. Front: 28mm - Rear: 19mm - Adjustable - G20/G22/G23/G26/G42 Dropping of the subframe is required so professional installation is highly recommended.

• Made of high tensile strength alloy steel with tubular (hollow) construction for maximum strength while limiting weight
• Rear bars are 2-hole adjustable allowing you to fine tune settings for environment or comfort preference
• Larger, more robust, bars; Front - 28mm size (vs. stock 26.1mm), Rear - 19mm size (vs. stock 17.8mm)
• Increased stiffness to combat roll; Front - 50% stiffer, Rear - 54-66% stiffer
• Includes polyurethane bushings and grease
• More stable at the limit
• More mechanical grip
• Less body roll

The Dinan D120-0630 adjustable front and rear sway bar set is engineered specifically for select BMW G20, G22, G23, G26, and G42 chassis. Designed to reduce body roll while preserving useful suspension movement, this upgrade helps keep the vehicle more level through corners, improving mechanical grip and providing a more planted, confident driving experience on the street, back roads, and track. The set includes a 28mm front sway bar and a 19mm rear sway bar, with the rear bar offering two adjustment positions for tuning handling response or comfort preference.
Constructed from high-tensile-strength alloy steel, the tubular hollow design delivers substantial stiffness while helping limit unnecessary weight. Compared with factory bars, the Dinan front bar is approximately 50% stiffer, while the rear bar provides approximately 54% to 66% greater stiffness depending on the selected adjustment position. This additional roll control improves stability near the limit, reduces unwanted chassis movement, and helps the tires maintain a more effective contact patch during cornering.
The Dinan D120-0630 kit includes polyurethane bushings and grease for a complete installation. Subframe removal is required, so professional installation is highly recommended. This sway bar set is designed for select BMW 330i, M340i, 430i, and M440i applications, including certain Gran Coupe models. Verify vehicle configuration and fitment before ordering to ensure compatibility with your BMW chassis and suspension setup.
