- The factory AMA baseline for non-wagon TD2 Dodge V8 cars specifies 55 x 2.5-inch semi-elliptical asymmetrical springs, a 90 lb/in spring rate and 110 lb/in wheel rate including the tire, five leaves, and no rear stabilizer. Its leaf-count footnotes stop at 413 cubic inches and do not define a 426 package. The January 1964 service catalog explicitly lists heavy-duty rear spring 2448 341 for 361, 383, and 426 engines; it also lists broad heavy-duty rear shock packages 2275 849 and 2275 848 (1.375-inch diameter), without tying either shock number specifically to every Ramcharger 426 build. · 1963 Dodge Polara Max Wedge

- Notes
- The 117-inch figure in the RM catalog is the ordinary Coronet wheelbase. A990 histories instead document special front spring hangers that moved the rear axle forward two inches for a 115-inch wheelbase; this is distinct from the much more radical A/FX altered-wheelbase cars. The ordinary Coronet AMA filing documents 56 x 2.50-inch asymmetric semi-elliptical rear springs and, in its broad 426 passenger-car column, a 112 lb/in spring rate and 5.5 leaves. Because the A990 used relocated hangers and competition equipment, those broad passenger-car spring figures are context only until an A990 engineering or build schedule confirms applicability. · 1965 Dodge Coronet A990 Super Stock

- Notes
- An exact A990 feature identifies 1965 factory Super Stock leaf springs with stock shocks. The ordinary 426 passenger-car AMA schedule for Belvedere sedan body codes documents 56 x 2.50-inch asymmetric semi-elliptical springs, a 112 lb/in spring rate, a 140 lb/in wheel rate including the tire, 800/840-pound design loads, 5.5 leaves, and no rear stabilizer or track bar. The service catalog lists non-wagon 426 rear springs 2495 060 right and 2495 061 left. Because neither factory table names A990 or separates delivery hardware from service replacement, those values and part numbers remain scoped factory context pending the A990 special-equipment schedule and car-specific inspection. · 1965 Plymouth Belvedere A990 Super Stock
