FAQ

What size belt do I need to purchase for the LS alternator bracket setup?

Your local auto parts store should be able to cross the part numbers. Here is the list based on which bracket, and if you are running standard or electric water pump:

Bracket / Water Pump Setup Belt Length Part Number
Type 1 or 2 with stock water pump/tensioner, stock diameter balancer 68.5"  685K6 or 6PK1740
Type 1 bracket, ELEC. PUMP, stock diameter balancer 48 5/8"  or 48 1/2" 6PK1235, 6PK1230, or 485K6
Type 2 bracket ELEC. PUMP, stock diameter balancer 49.75 or 50"  6PK1270,    6PK1265

 

Where else can I purchase your products?      Besides right here on our site, you can purchase on amazon or ebay.  Not all variations are available.

What is the difference in a type 1 and type 2 bracket?      The type 2 bracket is 1.5" shorter than the type 1, so it brings the alternator closer to the cylinder head.  This can aid in clearance for narrow LS swap applications. The type 2 will ONLY work with the Truck/5th gen Camaro balancer.    The type 1 will work with all three LS balancers, depending on which one you select when ordering.

Will your bracket work with an electric water pump?      Yes, either of the bracket versions will work with an electric water pump, including the Meziere.   You will orient the idler block 180 degrees from normal, so that the slot is in the bottom hole of cylinder head.  The pulley will tension against the top of the belt.  Click here for photo of belt routing.

 

What is the difference between the "small" and "large" fuel injector holder?

Both holders will ONLY work with 14mm diameter o-rings.  The small holder fits the newer Bosch EV-14 series and short PICO style injectors.  It has 1/8" NPT thread for the fuel fitting.  These are available with either a beveled or straight end.    The large holder fits the older Bosch EV-1 style injectors and Billet Atomizer injectors.  It has 1/4" NPT thread and is only available with the beveled end to go on a 3" diameter pipe.
