: Hi,
:
: Looking through my ARP price list last night
: and I noticed two versions of rod bolts,
: 142-6001 and 142-6002, no real difference in
: the description, and the price is similar. I
: don't have an ARP catalog, so I don't know
: what it says.
:
: Anyone know the difference in 6001/6002?
:
: thanks,
: mark

: The difference is in the bolt head. p/n
: 142-6001 has a round head with 1 flat side.
: 142-6002 has 2 flat sides opposite each
: other. This is per the 2001 ARP catalog.

: Thanks!
: Is the rod bolt with an extra flat for a
: special application? Aftermarket rod?
: Stroker crank? Just a different head design?
: Is one better than the other?
:
: thanks again,

: I have always used the 142-6001 with the one
: flat.
: These bolts always seem to need some head
: clearance work to fit / fully seat on the
: SL6 con rod. They do a good job of spreading
: the load out evenly around the bolt hole
: area.
: My guess is that the "2 flat side"
: bolts *may* fit without the additional bolt
: head clearance work but I have never used
: the 142-6002, has anyone out there used
: them?
