I did a search, but I didn't come up with the information that I was looking for, has anyone put together their own bump steer kit? Hoping to find out where people were able to source the parts from or a parts list that they used to make the kit.

Bump steer kits usually consists of two thick spacers that go under the steering rack and longer bolts.

I'll offer a counter point to the concerns about using spacers and a (semi) long bolt to attach a tie rod to the strut. There isn't THAT much force on a tie rod end, compared to other suspension joints. For a tie rod I'd rather have a single shear bolt as a weak link if a wheel takes a significant hit, and have the bolt bend, rather than having a double shear setup and transmit the entire force to the steering rack.
I've had a single shear setup on my racecar for many years and haven't had a problem yet. I do have a large washer on the outboard end of the rod end joint so it won't pop up in case of damage. |

Those spacers i was talking about (the ones posted by 914Sixer above) don't go on the tie-rods, they are used to drop the whole steering rack itself. (IMG:style_emoticons/default/shades.gif) |
