Q: What is the primary function of the K10325 bracket system?

A: This is an "AC-delete" serpentine conversion for the Small Block Chevy. It replaces the passenger-side AC compressor with a dedicated bracket that mounts a modern, automatic spring-style tensioner. This provides the same maintenance-free belt tension as a full accessory system for builders who do not require air conditioning.

Q: Which Small Block Chevy engines are compatible with this kit?

A: It fits all classic Gen 1 SBC engines (1969 and later). The passenger-side cylinder head must have at least one threaded mounting hole to accommodate the tensioner bracket. It is compatible with displacements from 262 to 400 cubic inches, including Vortec heads.

Q: What components are included in the K10325 package?

A: The kit includes brackets made of brushed satin 6061-T6 aircraft-grade aluminum, an automatic spring-style tensioner, idler pulleys, a water pump pulley, and an SBC crank pulley. All necessary spacers and zinc-coated fasteners are provided.

Q: What water pump is required for the K10325 system?

A: The system is designed around the reverse-rotation "long" water pump found on 1988–1995 Chevy trucks. This pump measures approximately 7" from the block mounting surface to the fan hub. A standard-rotation "V-belt" water pump will not work with this serpentine belt routing.

Q: Which power steering pump should be used with this specific part number?

A: The K10325 is designed for the compact GM Type-2 power steering pump. We recommend our all-aluminum pump with a 5.5" pulley (PN 10206-06) and our remote reservoir (PN K10267).

Q: What type of alternator does this bracket system mount?

A: The bracket is designed to accommodate the GM CS130 (standard on 1980s-90s GM vehicles). It also accepts modern high-output 1-wire units like the PowerMaster, PN 87861.

Q: Does this kit require a specific crankshaft pulley?

A: Yes, and it is included. The kit provides a dedicated SBC serpentine crank pulley. Unlike some other platforms, you do not need to hunt for a donor pulley or adapter; the provided unit ensures proper 6-rib belt alignment with the other accessories.

Q: How is the serpentine belt length determined?

A: This system is driven by a single 6-rib belt. Because alternator and power steering pulley sizes can vary, a belt is not included. The installation instructions provide suggested Gates part numbers and lengths. Always verify the fitment by checking the tensioner’s operating range marks after installation.

Q: Will this bracket system clear tall aftermarket valve covers?

A: Yes. The high-mount design of the tensioner and the tight-mount driver-side accessories clear tall, performance-style valve covers.

Q: Can I add A/C to this system later?

A: Yes. Since this kit uses a dedicated tensioner bracket on the passenger side where an AC compressor would normally sit, you can "upgrade" to an AC system in the future. You would simply replace the AC-delete tensioner bracket with a Kwik Performance Sanden Mini compressor bracket.  This upgrade is not on our website but we’d be happy to add it for you.  Just email or call.
