Alright, I am sick and tired of buying an autococker bolt from someone on here, only to have it not fit any of my cockers. So, for once, I would like to make a list of all the autococker bolt lengths in inches and which autococker versions they are compatible with.

Below I have posted all of my bolts with lengths (inches) and which guns they fit.




So, here are some of the measurements of my bolts:

5 5/8" - 5 11/16" will fit 98 STO / 99 STO / 97-99 EVO (with exceptions, see below)
6" will fit 2000 STO
6 5/16" will fit PMS Mark II (and other full size back block cockers)

Notice also that although bolts 1-6 appear to be basically the same length, bolt number 6 will NOT fit a 98-99 STO or a 97-99 EVO because the rear grip section of the bolt is much longer on 6 than on 1-5, which means the bolt will not line up with the bolt pin holes as seen here:

Maybe someone can explain what gun 6 fits...

Please list exactly what size bolt you have and what model autococker you have so we can compile a comprehensive list for reference. Once again, I have listed my results below. Thanks!


5 5/8" - 5 11/16" will fit 98 STO / 99 STO / 97-99 EVO (exception= #6 is '05 superstock length due to larger rear bolt grip)

6" will fit 2000 STO (Standard 2k - 2k4 length)

6 5/16" will fit PMS Mark II (and other full size back block cockers, usually older ones such as pre-2k)

The overall length doesn't really make a difference because the back of the bolt past the bolt pin hole can vary. A better measurement might be from the tip of the bolt to the center of the bolt pin hole.

it's the bolt you can find in a 05 Superstock.

nice job, it's always a pain to find the right bolt when building a Cocker...

9 thru 12 are older cockers, which had thicker backblocks. Backblocks stuck out about 1" from the back. Newer ones are in the 1/2" area.

So all the varying you see in size is cause of all the different size backblocks. Which varied from manufactures.

#7 looks like a standard 2k-2k4 bolt.

that bottom one looks very weird, the hole for the bolt pin is a lot further forward than the ones near it, so I think its actual length (length between the bolt pin and the air inlet) is closer to normal 2k length.

Alright, I just updated the list. Thanks for you input, I will also measure from the bolt pin holes to the front of the bolt ad MAD said.

PLEASE only post a reference length if you have tested it and measured it yourself! I want to keep the guessing on compatible models as minimal as possible.

Keep 'em coming!

Could be useful to add a picture of the 3 major styles of the back ends / back blocks of cockers. (pre-2k, 2k+ and evo). What also gets a little wacky are the back blocks where the pin goes through the top. I think that #8 bolt is one but may have the holes for both top and side bolt pins.

Great Presentation. I have been fortunate enough I accidentally always buy the right length. I always thought you had the mini bolt and standard bolt. Thanks for the eye opener.

Looking again, # doesnt look like the stock 99 sto bolt I have sitting at home.

The only one you're missing is work's P-block bolts. Those were between evo and 2k length.

Also - APBBolts.com (old Jam bolts maker) had some good info:
