Complete serpentine conversion for Ford Cleveland engines built around Unrivaled Engineering’s proven low-mount bracket system. This kit delivers tight packaging, clean belt alignment, and reliable high-RPM performance.
 
⚠️ NOTE:
The supplied bracket may be labelled "Low Mount A/C Bracket", but it is configured for power steering only and does not use an A/C compressor.
Images are for reference only. A standard Ford 6PK serpentine balancer pulley is supplied, not the Raptor Supercharger balancer pulley shown.
 
 
Available in black or clear anodised.
 
Included in every Cleveland power steering serpentine kit:
Low-mount power steering bracket system
Mid-mount alternator bracket
Alternator pulley 6PK
Balancer pulley 6PK
Water pump pulley – choose your style:
Pro Series
Classic Style
(Both offer the same performance, with the difference being their appearance. The Classic Style also allows the use of a mechanical engine fan if preferred).
Serpentine belt: 6PK1525
Eccentric idler pulley
Timing pointer
 
Optional add-ons (extra cost)
140amp Ford alternator - Aeroflow (black or chrome)
 
 
GM TYPE II Power Steering Pump Adapter Kit
Designed to integrate with the Unrivaled low-mount bracket system, allowing fitment of a GM Type II (remote reservoir) power steering pump. Not a standalone bracket - must be used with Unrivaled mounting system.
 
Compatibility:
Unrivaled Engineering low-mount bracket system
GM Type II remote reservoir power steering pump
Pump: Proflow PFEPSP200P
Pulley: Tuff Stuff 8487B
 
Design & Fitment
Positions pump tight to the engine block for maximum clearance
Compact design suits a wide range of engine bay configurations
This bracket is made to fit most vehicles and sits very tight and close to the engine block. As each car and engine combination can change, we advise checking there is ample room for a low mount bracket prior to purchase.
 
Notes:
Designed for use with the Unrivaled low-mount bracket system only
Power steering pump and pulley sold separately
Adapter bracket supplied in black only (not visible once installed)
 
 
Mid Mount Alternator Bracket
⚠ Check the spec diagram in images for dimensions, bolt sizes & compatible alternators before ordering.
 
Designed by an engine builder, this bracket is extremely strong and holds the alternator close to the factory location.
 
The key elements that set this mid mount bracket apart:
Made from strong 6061 billet alloy.
Space for idler pulley. This reduces the amount of belt shake/slap under high rpm loads, helping extend belt life.
Doesn't touch the cylinder heads.
Perfect fitment right out of the box - designed to directly replace factory alternator brackets and run the same backspacing so no need for extensive modifications if you are replacing your standard style alternator bracket.
 
Notes:
Check product pictures for alternator spec. This bracket will work with Powermaster & Aeroflow alternators along with many other brands.
Works on standard blocks with standard 5/16 bolt hole sizes. If your timing cover bolt sizes vary from 5/16 (such as for iron eagle blocks) then you will need to bring them back to oem spec by using thread inserts.
Designed to replace factory alternator bracket and will require 4 bolt raised face OEM spec harmonic balancer as seen on factory engines. If you have an aftermarket flat face balancer you will need to measure the balancer and purchase a raised hub for the balancer essentially bringing your aftermarket balancer back to factory measurement spec.
Recommended use is with mechanical water pump and idler pulley.
The image highlights the three mounting points (circled in red) on the engine block where our alternator brackets are designed to bolt up.
These brackets have been tested with aeroflow 140 amp ford alternators (Delco body) AF4273-1140
 
 
140amp Ford alternator Aeroflow (optional)
High-Output Charging:
140-amp Aeroflow alternator built for street and performance setups - supports electric fans, pumps, ignition systems, and modern accessories with stable charging at idle and cruise.
 
Direct-Fit Ford Mounting:
Bolts straight onto Ford applications for a simple, reliable install.
 
Important Notes:
Alternator must be properly grounded to the engine block. Painted or coated brackets can prevent grounding - run a dedicated ground wire if needed.
Battery must be 12.6V+ when fully charged. Weak batteries can cause alternator failure.
Do not disconnect the battery while running - this can destroy the alternator.
Alternator spins ~2.5× crankshaft speed; max safe alternator speed is 15,000 RPM. Engines above 6,000 RPMmust confirm pulley ratios. (Supplied pulley: 1.75".)
 
Alternator warranty:
Manufactured by Aeroflow Performance. Warranty claims follow Aeroflow’s terms. Unrivaled Engineering is not responsible for alternator performance or warranty handling.
