TRZ Motorsports Bump Steer Kit for Rack & Pinion Conversions - TRZ Spindle (4130 & Billet) (1968 - 1972 Chevelle A-Body) - 317-202-12T
Bump Steer Correction for 1968 - 1972 Chevelle A-Body with TRZ 4130 & Billet Spindles
The TRZ Motorsports Bump Steer Kit is engineered specifically for 1968 - 1972 Chevelle A-Body platforms equipped with TRZ billet or 4130 spindles. When converting to rack-and-pinion steering, steering geometry must be corrected - especially on lowered Chevelles where bump steer becomes far more noticeable. This kit provides the precise adjustment needed for smooth, predictable steering under acceleration, braking, and cornering.
TRZ spindles utilize TRZ's own 303 steering arms, which extend tie-rod length for improved geometry. This bump steer kit includes high-strength chrome-moly rod ends, Grade 8 hardware, and precision 6061 aluminum spacers to fine-tune steering alignment. Installation requires drilling the existing tapered spindle or steering arm hole to 1/2? to accept the straight-through hardware. Designed to work with both Standard and Narrowed Pinto racks (1/2-20 thread).
Note: Your cart may display "Narrowed Rack" based on your vehicle selection. Always verify rack length before ordering.

Frequently Asked Questions
Why does this kit differ from the factory spindle version?
TRZ spindles use TRZ steering arms, which extend tie-rod length, requiring a different adjustment range and spacer configuration.
Is drilling required for TRZ spindles?
Yes. The tapered hole on the spindle or steering arm must be drilled to 1/2? for the straight-through bump steer hardware.
