BMR Suspension MTCA002R Lower Control Arms (Chrome Moly)
The BMR MTCA002R lowers are designed for G-Body cars from 1982–2002. They use chrome moly construction and offer on-car adjustability with poly bushings. This makes them well-suited for enthusiasts who want precise alignment changes without removing arms for service. They are best for drivers seeking durable performance parts with a direct-fit approach.
Best for: Street-driven G-Body owners who want adjustable geometry and durable materials. Why selected: Chrome moly arms with in-car adjustability help dial in camber and toe for improved stability at speed.
Caution: Data emphasizes user-centric design; verify fitment for your exact year and sub-model prior to purchase to avoid misalignment.
G Body Adj Control Arm Pair
This control arm pair is vehicle-specific and developed in-house, with a focus on precise geometry and reliable support components. The company holds ISO 9001 and IATF 16949 certifications, signaling a quality-management approach aligned with automotive manufacturing standards.
Best for: Builders who value proven engineering processes and a tailored fit for G-Body frames. Why selected: In-house development supports tighter tolerances and predictable performance.
Caution: Design emphasis on specific vehicle platforms; confirm compatibility with your exact model year and sub-model.
Southside Machine Performance SSM Stage 1 Control Arm Kit
The SSM Stage 1 kit focuses on improved header clearance and geometry with a powdercoat finish for corrosion resistance. TIG welding improves structural integrity and it is designed to reduce bushing noise, contributing to a cleaner driving experience.
Best for: Performance-oriented drivers who need better clearance and geometry while keeping a clean install. Why selected: Combines improved arc welds with a protective finish and noise-reducing design.
Caution: Some users may still encounter fitment nuances with aftermarket headers; verify header clearance for your setup.
BMR Suspension Control Arm Bolt Kit
This kit provides the hardware needed for a clean, bolt-on control arm upgrade, including bolts, lock nuts, and washers. It is designed to complement BMR control arms and simplify installation on GM F-Body, G-Body, W-Body, X-Body, and Y-Body platforms from 1964–74.
Best for: DIY enthusiasts performing a full arm upgrade who want a complete hardware package. Why selected: Ready-to-install hardware streamlines the upgrade process and reduces missing components.
Caution: Check compatibility with your specific sub-model and year range to ensure the hardware matches the mounting points on your car.
Buying Guide: G-Body Chrome A-Arms
What should you look for in chrome A-arms?
Material quality and wall thickness directly affect strength and weight. Chrome moly is popular for durable performance. On-car adjustability helps dial in alignment without removal. Look for poly bushings if you want a firmer ride and precise steering feel.
How to choose the right length and geometry
Assess your current suspension setup and desired handling characteristics. Adjustable arms allow camber and caster changes, which can improve cornering and tire contact. For street use, prioritize stability and noise reduction; for track use, prioritize precise geometry and durability.
Maintenance and installation considerations
Ensure compatibility with your year, model, and existing steering/linkage parts. Check for proper clearance with headers and exhaust components. Some kits include hardware and are designed for straightforward bolt-on installs; others require additional machining or alignment work.
Pros and cons at a glance
- Chrome moly arms: High strength; more weight; long-term corrosion resistance with proper care.
- Poly bushings: Quieter, better steering response; may wear differently than rubber over time.
- On-car adjustability: Easier alignment; potential added maintenance to keep settings stable.
- Vehicle-specific designs: Precise fitment; verify year/model compatibility before purchase.
Installation and best use cases
Best for enthusiasts performing a suspension refresh with a focus on geometry control. Choose this if you want to improve handling without fabricating mounting points. If you frequently swap between street and strip, look for a balance of comfort and performance.
FAQ
- Q: Do chrome A-arms fit all G-Body years? A: Fitment varies by year and sub-model; verify compatibility with your vehicle’s configuration.
- Q: Are on-car adjustable arms worth it for daily driving? A: They can help fine-tune alignment; consider maintenance needs and stability.
- Q: What are poly bushings versus rubber ones? A: Poly bushings offer firmer steering feel and longer life; rubber provides a smoother ride but may wear faster.
- Q: Is a bolt kit necessary for upgrading arms? A: A complete hardware kit can simplify installation and reduce missing parts.
- Q: Should I upgrade multiple suspension components at once? A: For consistent handling gains, align arms with compatible components (rods, tie rods, and bushings) during a single upgrade.
- Q: Do these arms require professional alignment after install? A: Yes, post-install alignment is recommended to realize tuning benefits.
