1998-2002 LS1 F-Body Front Control Arms

Decrease overall weight and more importantly "unsprung" weight with a set of BMR tubular front a-arms. BMR A-arms are manufactured from DOM tubular steel and feature precision laser cut mounting plates and CNC milled ball joint cups to provide you with a very rigid, high quality upgrade to the factory suspension. These a-arms are built extremely rigid and are equally at home on the street or at the track, whether it be drag racing or autocross. Both upper and lower a-arms are compatible with all stock components and come equipped with swaybar mounts unlike other "race only" setups.

All of BMR's suspension and chassis components are powdercoated in black hammertone (click link for color sample.) This color was chosen for its neutral characteristics and is a very durable hybrid powdercoat, designed specifically for outdoor environments.

 

Lower A-arms:

These precision made a-arms feature 1.625" and 1.25" DOM tubing construction with CNC milled balljoint cups and laser cut mounting plates. A new, heavy duty, greasable ball joint comes pre-installed. Mounts consist of a combination of low deflection polyurethane bushings and a chrome moly, teflon lined severe duty rod-end with stainless steel mounting spacers. Save 7 lbs. of unsprung weight and increase the rigidity of your front suspension at the same time!





Upper A-arm features include:

• 1.25" DOM tubing with 3/16" ball joint mount
• Standard Arms include low deflection polyurethane mounting bushings
• Adjustable version allows additional alignment adjustability utilizing chrome moly, teflon lined rod-ends
• 3 pounds lighter than stock
• 3 degree improved balljoint angle for lowered cars
• Adjustable Upper A-Arms are not recommended for street use.

Lower the front of your 4th Generation F-body 1" without affecting suspension travel with a set of Lowering A-arms from BMR Fabrication. Based on our well proven traditional A-arm design, these lowering A-arms are constructed from a combination of 1-5/8" and 1-1/4" DOM tubing and feature 3/16" laser cut steel plates and CNC machined ball joint cups. The BMR Lowering A-arms (AA020) utilize a combination of low-deflection, internally fluted polyurethane bushings and Teflon-lined XR series spherical rod ends with stainless spacers. The result is a high quality tubular A-arm that not only reduces weight by 10 lbs. but lowers the vehicle without the typical geometry and alignment concerns. Installation time is only 2-3 hours. Available in black hammertone or red powdercoat.

PA Racing's Tubular A-Arms are available in either mild steel or chrome moly, and feature double spherical bushings for maximum control.  A new ball-joint is included and comes pre-installed for ease in installation. Available in black or red powdercoated finish.

Spohn Performance's front lower a-arms set a new, higher standard of performance and quality. When we designed our a-arms, we had two goals in mind. One was to provide the performance capabilities needed for the toughest race tracks, the second was to provide the strength and durability required for the demands of a daily driven vehicle. We're proud to say that we have accomplished both. Spohn's front lower a-arms are a true "A" arm rather than a "V" arm. This provides maximum rigidity and equalizes forces delivered in to the k-member. Spohn control arms are gusseted in critical areas to ensure that a weld never breaks. The Spohn front control arms can be installed on a stock k-member, or on aftermarket k-members. They decrease overall weight, and more importantly - "unsprung" weight. If you are looking for the highest quality front suspension components for the fourth generation F-Body, you just found them!
