HOLLEY MID LSA/LS ACCESSORY DRIVE BRACKET KIT - ALTERNATOR

Small Block Chevrolet - Gen III/IV - LSA/LS

If you're looking to swap an LSA or LS engine into your vehicle but your engine didn't come with an alternator bracket or the factory setup is too wide to fit your project, Holley has the answer. The 20-166 Bracket tucks the Alternator in closer toward the engine when compared to the original LSA accessories, giving more clearance where needed. These brackets look truly at home on the LSA engine, so much so that nobody will realize it didn't come from factory this way.

  • Compatible with the original LSA damper/pulley and similar aftermarket versions
  • Compatible with all Holley Alternators
  • Notably more clearance to swap applications than other options
  • Compatible with Holley P/N 20-160 compact SD7 A/C kit
  • Compatible with LSA and 2010-15 LS Camaro water pumps
  • OE pulley ratios for optimal accessory performance, allows for larger SC crank pulley
