Description

The Speed Kit 3 optimizes geometry and tire contact for GM A-Body vehicles. It features patented Swivel-Links™ for articulation, pinion angle, and/or wheelbase adjustments. The kit includes a tubular rear sway bar, Speed Kit springs, and double adjustable JRi shocks for precise tuning and improved ride quality. This part requires a Moser rear axle and excludes wagon applications. The bushing included may not fit some 1964 A-Body axle housings (due to diameter); a smaller bushing (ø1.360") is available as Detroit Speed P/N: 99040249.
