Product Description

R4 AC bracket for LS engines with Truck/SUV (1999-2013) and Camaro (2010-15) crank pulley and water pump spacing.

This bracket mounts the old school OEM R4 compressor just outside the passenger’s side valve cover and is driven by one main 6-rib serpentine belt.

Why relocate the AC compressor for an LS swap?
  • GM made a fantastic engine with the LS design, but they didn’t always put the accessories in the best location for us engine-swapping hotrodders.
    By locating the AC compressor just outside the passenger side cylinder head you solve the possible frame clearance issues with chassis such as:
    • Camaro
      • 1st Gen (1967-69)
      • 2nd Gen (1970-81)
      • 3rd Gen (1982-92)
    • Chevelle (and other A-body cars, 1964-77)
    • Malibu (and other G-Body cars, 1978-88)
    • Full size Chevy pickups (1955+)
    • S10 pickups and S10 Blazers (1982-2004)
What driver’s side bracket works with this AC bracket?

Use with the Kwik Performance Idler Relocation kit K10618 which allows you to use a low profile intake manifold and 2010+ Camaro water pump with OEM truck alternator/power-steering bracket.

Don't want to spend time modifying, cleaning and painting the OEM bracket? Our K10611 (pictured) bracket allows you to reuse your alternator and truck "P-series" power steering pump. We also tucked the pump for added steering gear and A-arm clearance.

Alternatively, our Wide Mount alternator/ (Type 2) power-steering bracket K10168 allows more hood clearance and provides more steering gear / A-arm room.

  • Check dimensions for fender clearance if application is early Truck or Street Rod.

  • Camaros (2010-2015)
