Muscle Cars & Classics always recommends professional installation of our products. Buyer assumes risk of damage caused by improper installation.

Our tubular rear sway bars offer multiple advantages over the non-effective stock rear bar.

First, unlike the factory bar, ours attaches to the rear end housing and to the chassis crossmember as opposed to the stock lower control arm mounted bar. By using the chassis to stabilize the rear axle as opposed to the opposite control arm, we are able to minimize deflection as your car is placed under a heavy cornering load.

Second, the Detroit Speed bars mount to the chassis with a low-friction ball style end-link, allowing free articulation of the bar, eliminating binding through the range of rear suspension travel. Our bar is also made of 1 inch tubular 520 DOM for added strength and works for most street applications. The 1-1/8 inch sway bar is made for a more competitive natured vehicle.

The bars come powdercoated in a high gloss black finish, includes all necessary mounting hardware and has split lock collars that positively locate the Anti-roll bar in the correct location. The Anti-roll bars offers dual rate adjustment for increased vehicle tuning. We bend all of our Anti-roll bars in-house. This allows us to control quality so you receive the best product for your money.
