Frame and front cross-member clearance issues have been a real problem when installing GM LS engines. We have put together a package that relocates the A/C compressor to the upper right hand (passenger side) of the engine. This package also eliminates the need for a second belt to drive the compressors and converts your drive system to a single serpentine belt driven system.

Package includes:

  • New, natural finish, Sanden 508 style compressor for R-134A
  • Lightweight 6061-T6 aluminum brackets
  • Pulleys (smooth non-ribbed idler pulley is Gates 38012 or equivalent)
  • Zinc plated fasteners
  • Serpentine Belt (for use with Pace Pac LS Serp kits, different belt length may be required when using this package with other drive systems)

Grooved idler pulley replacement part number is GM 12569301
