A-arms are one of the most important, yet overlooked suspension components. They are the direct link between the front wheels and the chassis. Any deflection causes a change in alignment, which results in poor performance and driving feel. Fabricated from heavy-duty 1.25-inch, 0.095-inch wall DOM tubing with laser-cut, CNC-formed plate steel plate, deflection is eliminated with A-arms from BMR Suspension. BMR’s AA025 Lower A-arms are equipped with greasable heavy-duty ball joints, 95-durometer polyurethane bushings (front mount), and greasable Delrin bushings (rear mount) to handle the high loads. Polyurethane bushings add a solid, more responsive feel over the stock rubber bushings. BMR’s bushings are internally fluted, which allows grease to evenly coat the inner sleeve. These flutes also direct grease to the outer edge of the bushing, keeping the thrust surface lubricated. This efficient lubrication ensures quiet, reliable operation over the life of the bushings. The combination of poly and Delrin bushings gives you improved steering feel and responsiveness for any for of driving. Based on our well proven traditional A-arm design, these Handling A-arms feature ¾” taller ball joints to raise the roll center height on lowered vehicles for improved handling.

BMR’s AA025 lower A-arms eliminate A-arm deflection, greatly improving steering feel and response in normal and performance driving situations. The polyurethane and Delrin bushings add strength and reduce deflection over the stock rubber bushing, while still absorbing much of the NVH. The means you get a great blend of performance and comfort. Designed for street performance, drag race, and handling, and pro-touring applications, BMR lower A-arms are engineered to give you improved geometry and increased lateral grip during cornering situations.

BMR Suspension AA025 Non-Adjustable Lower A-arms are available in black hammertone and red powdercoat for long-lasting good looks. Installation time is 3-4 hours. Proudly made in the U.S.A.

Control arm hardware kit RH014 (Includes upper and lower control arm hardware - Highly Recommended) also available.


*All S197 BMR K-Members include all new control arm hardware, so it is not necessary to purchase the RH014 separately.

NOTE: BMR Suspension highly recommends the purchase and installation of a bumpsteer kit when installing "tall" ball joints on the S197 Mustang platform.


***Attention 2010 Mustang Customers***
According to representatives from Ford Motor Company, all 2010 Mustangs built before August 2009 have 18 millimeter ball joints on the front lower A-arms. If your 2010 Mustang was built before August 2009, you need to purchase BMR A-arms for a 2005-2009 Mustang (AA010, AA019, AA023, or AA024).

There should be a manufacturing decal on the driver side door jamb of your Mustang. The date on the upper left hand corner is the build date.

All 2011-2014 have 19 millimeter ball joints on the front lower A-arms. All 2005-2009 Mustangs have 18 millimeter ball joints on the front lower A-arms.

If you are uncertain of the build date for your Mustang, please measure the ball joint stud diameter before ordering your BMR front lower A-arms. If you have any questions, please call BMR Suspension directly and we will help you select the correct A-arms.
