Broken/failed rear shock bolts

[D-CEL]

Just another quick FYI for you SPF guys that haven’t checked your rear shock bolts.

DO IT!

I had two like this and one not quite so bad.

Wow!

I had a friend have a bad accident, thankfully not injured, due to this same thing. 600hp spinning uncontrolable with wheel inside fender sending the car off the road. I am not in the know about the SPF frame however I heard they are adjustable via a bolt, which can shear as it did with my friend.

I suggest setting your ride hieght then weld it solid.......

This issue has been known for a year or so, and there is a fix.

Does this issue apply to all SPF car numbers? Or has this issue been fixed at some point.

SPF tech bulletin here with chassis number information....

We do no cost inspections of cars for any SPF owner.

If I remember correctly, the factory beefed up the design at around #1670. Cars made after that are still subject to some sheer BUT they used heavier bolts and welded sleeves into the chassis hole to minimize the stress. If you have a car above 1670, the bolts should continue to be monitored and treated as a regular maintenance item. Lower car numbers should DEFINITELY buy the upgraded mounts and put the issue to rest. As for me, even if I had one of the later cars, I would invest a couple of hundred bucks in the upgrade and eliminate any concern. As much as we dump into "fun stuff", it makes at least as much sense to invest in safety.
