VCCA Home Forums TECHNICAL - GENERAL Vendors & Suppliers - Parts Rocker arm shaft kit

I bought some parts as a lot, and it included this rocker arm shaft kit.
It looks a lot like the parts in my 1932 Chevrolet, but springs are a little different and sharfs are longer than in my car.
I don`t get any information when I Google Atlas and partno 15013.
I´m pretty sure it`s for Chevrolet.

Can anybody tell which Chevrolet it will fit?

I believe there was point at which Chevy no longer had bushings in the rockers (maybe 1941) Since your kit has no bushings, the kit is probably from that time and later.
The 1951 parts catalog says '40-'51 rocker shafts are the same, but no length is given.

Rocker arm shaft length

1929-1931 11 7/16" -OIL HOLES DRILLED ON BOTH SIDES
1932-1934 except 1934 Master 11 /7/16 , oil holes on on side
1934 Master and all 1935-1936 11 3/8 -OIL HOLES DRILLED ON ONE SIDE.
1937-1939 12 1/16'

I measure them to 318 mm which equals to 12,5", will that fit any Chevrolet model?

I would put my vote on 1940 and up. The 39 shafts had a groove on both ends, I believe.

From what I have used before in rebuilding rocker arm sets, the set shown in the picture will fit 1940-62 Chevy 6. The set is made to fit 1940-53 with the 2 studs to hold the valve cover on but the shafts, springs, bolts and keepers are the same.

Thank you all for the information.
