QA1 52855 High Clearance Front & Rear Sway Bar Set 1-3/8" & 1-1/4" 4130 Chromoly

The QA1 52855 is a complete front and rear high clearance sway bar set engineered specifically for 1978–1988 GM G-Body vehicles. This matched set features a 1-3/8" diameter front bar and a 1-1/4" diameter rear bar, both precision-crafted from lightweight 4130 chromoly steel with a gloss black powder coat finish for long-lasting corrosion resistance and a clean under-car appearance.

What sets this kit apart is its high clearance design — 4" narrower than OEM sway bars — allowing full turning radius with wheels up to 24" in diameter. The bars are compatible with both stock GM G-Body OEM front frames and notched front frame rails, making this an ideal upgrade for custom and big-wheel builds alike.
