Borgeson Power Steering Box, 1988-98 Chevy/GMC OBS, Street & Performance 12.7:1

Borgeson's Street & Performance quick-ratio power steering box is the only quick-ratio replacement for the Delphi 800-series gear in 1988-1998 Chevy/GMC OBS trucks and fullsize SUVs. The 12.7:1 ratio delivers a firm, modern feel with fewer turns lock-to-lock. It bolts to the stock location and reuses the factory pitman arm, steering shaft, and power steering hoses.

Fitment: 1988-1998 Chevrolet/GMC OBS trucks and fullsize SUVs (incl. Tahoe/Suburban applications).
