[TR] IRS rear shock question

[Cliff Hansen]

Is that bolt 3/8 or 7/16”?  The parts manual assigns HU1010, which the hardware catalog translates as 7/16” UNF x 1.25”. If I was to guess, I’d say the parts manual is wrong; I don’t recall that bolt being 7/16”.

I started using ARP bolts that have a different size socket for the head but still is 3/8-24 in size. With these there is
Room for the socket and can get them really tight.

Summit has them in 3/8 – 24 X1.00 with a head that is 12 point and takes a 7/16 socket. Also has a built in flange washer. With this you can use a 7/16 12 point socket. Summit number ARP-744-1000. Package of 5 $12.59

I also use a 3/8-24 nut that also takes a 7/16 12 point socket. Summit number ARP-300-8332. Package of
10 $13.59

A regular 3/8 – 24 bolt takes a 9/16 socket.

Works for me

I can't recall exactly what I did there, but changing the standard hardware is a good place to start.  The fatter the purchase on the shock side the better.  I think I used a grade8 hard washer to grab as much of the shock as possible under the bolt head.  I think an allen head bolt might provide a better purchase for tightening, or I ground down a 9/16" socket to better fit the bolt head.  I think I used a longer bolts too.  Adding another nut to lock things is place.  If I get a chance, I'll take a good look at what I did and get back to you.  The frame mount can get worn out of round too, if it's been loose a few times.
