240 Redrilled Front Hubs

Regular price $18.00 $0.00 Unit price per

This product is a modified 240 front wheel hub that allows for alternate Bolt Circle Diameters (BCD).

These can be very useful for the mounting of wheels intended for other vehicles, especially for vehicles with rear axle swaps that may have different BCD in the rear than in the front.

The hole diameter that we are using is 12.55mm which matches Late Model GM applications.

Compatible ARP wheel stud part numbers (the ones that we use and supply)

#100-7708   -  M12x1.5

#100-7731   -  1/2x20  

If you plan to use a 1/2-20 thread stud, please let us know as the hole diameter needs to be enlarged slightly for the required clearance.

The max bolt pattern that the 240 hubs can accommodate is 5x114.3 mm (5x4.5"). We can redrill other patterns such as 5x112, 5x110, and 5x100 as well.

The purchase price includes 2 wheel hub cores ($18 each) which we will refund if we receive the cores back.   

The machining service is $55 per pair of hubs and we can include ARP studs and install them into the hubs for an additional charge

Frequently Asked Question: 

Q: Do you need to redrill the rotors to use these hubs

A: No you do not.  With 100 through 112, you do not need to modify the rotors at all, they will simply slide on due to the large diameter holes in the rotor to clear the shoulder of the factory studs.   With the common 114.3mm pattern, there is a slight interference of ~1mm.  This can easily be removed with a round or half-round hand file and should take about 10 minutes per rotor. 

Q: Can you drill hubs to 5x120?  
A: No, there is not enough material to safely drill a 5x120 hole pattern onto a Volvo 240 hub, the outside diameter is too small.  

 

Q: Can I reuse my stock wheel studs?   

A: No, not on the alternate pattern.  The reason for this change is we want to leave as much material intact as possible on the wheel hub.  The larger diameter patterns like 5 x 114.3 would make the wheel hub weak if a stock-sized stud was used in that position.   They would also necessitate more material removal from the rotors to clear the large shoulders on the stock studs.
