SPL Parts 1990-2005 Mazda Miata (NA/NB) Bumpsteer Adjustable Tie Rod Ends (Manual Rack Only)

Fits 1990-2005 Mazda Miata (NA/NB) models equipped with a factory manual steering rack. Part number: SPL TRE NAMR.

The SPL NA/NB Miata Tie Rod Kit provides critical bumpsteer adjustment for lowered vehicles. By utilizing precision-machined spacers to relocate the tie rod end pivot point, these units allow you to align the steering geometry with the suspension arms. This optimization significantly reduces dynamic toe change, also known as bumpsteer, as the suspension cycles through its travel during cornering or over uneven road surfaces.

Constructed for professional-grade durability, these tie rod ends replace soft factory bushings with maintenance-free, US-made FK PTFE-lined spherical bearings. These self-cleaning bearings eliminate deflection, resulting in more predictable steering response, reduced front tire shoulder wear, and improved stability across track curbing and rough pavement.

• Materials: 6061-T6 aluminum turnbuckles and 4140 chromoly steel tapered studs.
• Hardware: 304 stainless steel spacers (1/8" and 1/4") and anodized titanium fasteners.
• Precision Bearings: FK PTFE-lined spherical bearings for smooth, bind-free operation.
• Weight: Lightweight design at 2.52 lbs (1.14 kg) per side.
• Adjustment: Engineered for precise dynamic geometry and bumpsteer correction.

Proudly engineered and assembled in the USA.
