78-88 G-Body Rear Brake Cylinder Braces
78-88 Malibu Elcamino Monte Carlo Grand National Regal Cutlass 442 Grand Prix
78-88 G-Body / A-Body Rear Brake Cylinder Braces – Brand new braces, each lot consists of a pair of braces (2) one for each rear brake assembly (L&R).
The rear brake cylinders on these vehicles are fastened in place via a round metal retaining clip that snaps in place retaining the brake cylinder to the backing plates. During hard braking the brake cylinders have a tendency to rotate which may cause the rear brakes to lockup prematurely.
This a simple bolt on modification that keeps the rear brake cylinders fastened tight and from rotating.
The first couple pictures are of the actual braces. The last couple pictures are from a magazine article
detailing the usage & installation of these braces

RideTech 11324799 Rear Dual Rate Coil Springs, 78-88 GM G Body
Info
2″ drop spring StreetGRIP rear lowering coil springs improve the handling, ride quality and stance of your 1978-1988 GM B-Body muscle car including Monte Carlo, Monte Carlo SS, Malibu, Regal, Grand National, 442, Hurst/Olds, Lemans, Grand Prix, El Camino and T-Type. The dual-rate design provides the best of both worlds with the soft rate section allowing the vehicle to transition small road irregularities via a soft spring rate. When the vehicle compresses the spring far enough (through large bumps or cornering), these coil springs transition to the firmer spring rate to control body roll and movement. We work closely with Hyperco to develop g-body specific spring rates to ensure the best ride and handling.
This item is being shipped to you directly from the manufacturer and is subject to an increased handling time. Delivery estimates that include the handling time are displayed on the “Shipping and Payments” tab.
