The best BMR Suspension parts in this collection are its boxed lower control arms and bushing kits for classic GM A-Body and G-Body cars and the 2008-2009 Pontiac G8. Shoppers restoring or tightening up a 1964-1972 A-Body, a 1978-1987 G-Body, or a G8 should start with the control arms and bushings listed for their exact platform, in their choice of Red or Black Hammertone where offered.
Worn bushings and flexible factory arms let the suspension move in ways that hurt traction. Boxed arms and fresh bushings address that at its source. This is a platform-specific collection, not a universal one: A-Body, G-Body, and G8 parts do not interchange, so check your year and model carefully. See also the wider suspension, suspension bushings, and control arms ranges.
About the brands
BMR Suspension is the sole brand here, represented by non-adjustable boxed lower control arms for the 1964-1972 A-Body and 1978-1987 G-Body, a Pro-Touring upper A-arm with tall ball joint for the A-Body, and bushing kits for the 2008-2009 Pontiac G8. Examples include the G-Body boxed lower control arms in Black Hammertone, the A-Body Pro-Touring upper A-arms, and the G8 rear upper inner bushing kit. Polyurethane, Delrin, and elastomer options appear across the listings, so read each product's material before ordering.
Prothane is known for polyurethane bushings and mounts, and is a common cross-shop for owners whose main problem is perished rubber rather than the arms themselves. Compare Prothane when you are refreshing bushings only, and BMR when you want the arm and bushing as a matched boxed assembly.
Energy Suspension is another polyurethane specialist, widely used for bushing kits on older platforms where factory rubber has aged out. Its approach is bushing-led, while this BMR collection leads with complete boxed arms for the A-Body and G-Body plus targeted G8 bushing kits.
Hotchkis is known for complete handling packages for muscle cars, including sway bars and suspension kits aimed at road manners as well as grip. Shoppers planning a full chassis refresh often compare Hotchkis kits with individual BMR arms and bushings. For background reading, see how aftermarket parts improve handling.
Frequently asked questions
Will BMR A-Body arms fit my G-Body, or vice versa?
No fitment should be assumed between platforms. The arms in this collection are listed separately for 1964-1972 A-Body and 1978-1987 G-Body cars, and the bushing kits are listed for the 2008-2009 Pontiac G8. Check your year and model against the individual listing.
What is the difference between polyurethane, Delrin, and elastomer bushings?
They differ in stiffness and compliance, and this collection uses all three. Choose from the specific product description rather than assuming one material suits every position.
Are these control arms adjustable?
The boxed lower control arms in this collection are listed as non-adjustable. The A-Body upper A-arm is a Pro-Touring design with a tall ball joint. Read the individual listing if alignment adjustment is a priority for your build.
Is fitting control arms a driveway job?
Control-arm and bushing work typically needs the car safely supported, and bushings can require pressing tools. Many owners have a shop fit them and then set the alignment, especially on a Pro-Touring build.
