Description
The 1930–1935 Chevy Car SuperSlide Parallel Rear Leaf Spring Kit by Posies (Part #8021S) sets the industry standard for early Chevrolet parallel leaf spring conversions. Engineered specifically for 1930 through 1935 Chevy passenger cars, this complete rear package eliminates awkward tire-to-fender gaps while replacing obsolete torque-tube setups with smooth-riding, custom-tuned parallel leaf spring geometry.
Unlike stiff "one-size-fits-all" universal aftermarket springs, these SuperSlide springs feature Posies' signature moly-nylon inter-leaf buttons embedded between leaf tips. This design eliminates metal-to-metal spring friction, rust binding, and harsh squeaks for an exceptionally soft, quiet, and reliable ride.
Key Features & Design Highlights
Lowered Street Rod Stance: Designed to drop the rear end of 1933–1935 Chevy bodies, closing the tire-to-fender gap for a level, aggressive profile.
Vehicle-Specific Spring Tuning: Custom-engineered spring rates matched specifically to the chassis weight and suspension dynamics of 1930s Chevrolets.
SuperSlide Friction Control: Moly-nylon buttons prevent leaf-on-leaf grinding and friction, providing superior suspension articulation and road isolation.
Complete Hardware & Shock Package: Includes SuperSlide leaf springs, frame mounting brackets, rear shackles, axle saddles, U-bolts, axle spring plates, shock absorbers, and hardware.
American-Made Quality: Manufactured, hand-assembled, and tour-tested in the USA using premium tempered spring steel.

Fabrication & Assembly Guidance
Upper Shock Mount Requirement: Due to original frame width and contour variances across 1933–1935 Chevy model years, an upper shock bar is not included. Posies recommends welding a length of box tubing crossmember between the frame rails to mount the included upper shock brackets.
Final Welding Notice: As with all street rod suspension components, frame hangers and mounting brackets must be fully welded to the frame before vehicle operation.
