UMI Performance 4061 Bump Steer Kit for A-Body 1964-1970

The UMI Performance 4061 Bump Steer Kit is engineered to reduce or eliminate toe change during suspension travel, commonly known as "bump steer." Designed specifically for GM A-Body vehicles (1964-1970), this direct bolt-in kit significantly improves handling precision, straight-line stability, and overall steering response by maintaining proper tie rod geometry throughout the suspension's range of motion.

Key Features:

• 4140 Chrome-Moly Construction: High-strength CrMo studs provide exceptional durability for street and track use
• Adjustable Height Design: Includes laser-cut spacers in 0.125", 0.1875", and 0.250" thicknesses to relocate the outer tie rod end lower (or higher if necessary) for optimal geometry
• Premium 6061-T6 Aluminum Adjuster: Hard anodized hex sleeve with 5/8" RH and 5/8" LH threads, 9.200" sleeve length for lightweight strength and corrosion resistance
• Bolt-On Installation: Direct fit design works with factory inner tie rods and spindles—no drilling required
• Race-Quality Components: Includes high-performance rod ends, jam nuts, and locking hardware
• Factory Taper Fit: Studs feature exact OEM taper for precise, secure fitment
• Complete Kit: Comes with detailed instructions and technical reference links
• USA Made: 100% designed and manufactured in Philipsburg, Pennsylvania

Battle-tested on UMI's own A-Body development vehicle, this bump steer correction kit delivers professional-grade suspension tuning for muscle car restorations, street performance builds, and competitive racing applications. By maintaining consistent tie rod angles throughout compression and rebound, the kit eliminates unpredictable steering inputs and enhances driver confidence in all driving conditions.
