GM 4.3, 5.0, 5.7 Pre-Vortec Belt Driven Compressor Kit | 1988-1995 OBS C/K Truck

Add reliable onboard air to your 1988-1995 OBS Chevy/GMC C/K truck running a 4.3L, 5.0L, or 5.7L Pre-Vortec engine. This belt-driven compressor kit mounts a brand new York 210 compressor directly to your factory accessory drive - no electric compressor, no duty-cycle limits, just steady air supply for train horns, air lockers, air tools, or a full onboard air suspension setup.

Standard Kit includes:

• NEW (not remanufactured) York 210 compressor w/ clutch
• 2x head fittings tapped to NPT w/ o-rings
• 36" stainless braided leader hose
• Lasered/powdercoated 1/4" steel compressor bracket
• Dipstick and filler syringe
• Intake filter/silencer
• Gates idler pulley and machined idler spacer
• Mounting hardware
• Full installation instructions with serpentine belt length reference

York SLM Upgrade (Super Low Maintenance): Same benefits as the standard York, plus internal modifications (oil control ring pistons, crankcase venting into intake, intake baffling, finned head) that cut oil consumption dramatically - side-by-side testing shows 1oz of oil use per 1 hour runtime on a standard York vs. 1oz per 50 hours on the SLM.

Fitment: GM 90-95 4.3, 5.0, 5.7 TRUCK engines (confirm visually against installation instructions). Designed for GMT400 C/K bodystyle trucks; 90-91 squarebody carryover trucks/SUVs may require additional fitment consideration.
