73-91 GM C10 Sway Bar Bushings 1-1/16in

The 73-91 GM C10 Sway Bar Bushings 1-1/16in from PROTHANE represent a critical upgrade for classic Chevy truck chassis tuning and handling refinement. Original rubber bushings on C10s, Suburbans, and full-size GM trucks degrade over decades, causing excessive body roll, vague steering response, and suspension geometry creep during cornering. This complete set of four polyurethane bushings restores anti-sway bar compliance while dramatically tightening steering feedback and lateral stability—essential for drivers who demand predictable handling during spirited driving or trailering loads.

PROTHANE's polyurethane construction delivers superior durability compared to OEM rubber compounds, resisting ozone, UV exposure, and thermal cycling that plague vintage truck suspensions. The 1-1/16 inch bushing diameter precisely matches factory sway bar diameter specifications for 73–91 GM C10 trucks and compatible full-size platforms. Non-greasable design eliminates maintenance intervals while the polyurethane material maintains consistent spring rates across temperature extremes—unlike rubber, which hardens in winter and softens in heat. Installation requires removal of the front sway bar and old bushing hardware; bushings slide over the bar shaft and secure via original clamps or brackets.

Restoration enthusiasts, street rodders, and vintage truck owners will notice immediate improvements in turn-in response and reduced body lean on highway curves or gravel roads. The set of four covers both sides of the sway bar system and fits GM Fullsize SUVs, trucks, and vans from 1973 through 1994, making this a universal upgrade for C10 Chevrolets and K10 four-wheel-drive variants. Professional installation is recommended; expect 30–60 minutes of shop time depending on bolt corrosion and access. Pair these bushings with updated shocks and springs for a complete front-end refresh that restores compliance without sacrificing the classic truck character.
