Rear shock mount bending

[kcjaz]

M19 bolts look hard to find anyone know of a source? I’ve checked Fastenal and Bolt Depot. 3/4” is probably OK but I get hung up on keeping things metric.

Might check with @MTKID as he did this for AHC long travel.

I’m thinking now is the time to figure out raising the mount. There are already two promising looking holes in the mounting bracket.

If this works it would add a nice amount of more droop and I could cut off the bottoms of the bracket for more clearance. I need to make sure the shock won’t bottom out and potentially extend brake lines and breather tube. Anything else I need to check?

Hey @Turbo, I was looking at your shock mount relo bracket and thought it was essentially using the holes above the mounting pin as the relocated shock eye center but see that your bracket offsets that a bit.

If I just through bolt my BP51 shocks through those higher holes, the change in angle will cause the upper mount bushings to be compressed at a different angle than the OEM setup but will that really cause an issue? The angle changes as the axle goes up and down. Did you design your bracket to maintain the angle or to make it a bolt on mod not requiring enlarging the stock holes to accommodate a 3/4” bolt?

Here’s a couple photos I found of the 3/4” bolt we used and a small sleeve of steel tubing welded to a small square of plate to space out the lower shock from the support. Seems to have worked fine and is still the same. I like the idea of cutting off the bottom of my lower shock support too but I just can’t bring myself to do it.

Hope this helps if this is the route you take.

I also have LX600 shocks sitting on the shelf to eventually try seeing if they could even mount in this same location and give just a little more droop.

Yeah, my spacer moves the shock mount up and inboard to keep the bushing in a more oem position.

Compared to hole above oem pin.

So this is my plan. I've seen a couple post about enlarging the upper hole to accept a proper sized bole for the shock, welding it in properly the cutting the lower mount off.

I've put in Perry parts extended bumps in and have checked, looks like they will work perfectly for that second hole. I also have metal tech LCAs and they give extra movement in the axle

Do you think the bent shock mount and enlarged upper hole was from the Swell?

Make sure the rear springs, mainly the drivers side, won’t fall out at full droop. Also expect to extend the diff breather hose and the brake lines… not that I’ve done this, but I did look into it. Of course make sure shock doesn’t bottom out - remember the PP bumps are progressive so there likely will be more travel than just sitting on them without springs installed.

I’m looking forward to following along and eventually doing something similar one of these days…

Springs stay in, will probably add a redundant retainer though. And yeah diff/brake lines are on the parts table just haven't done it. I'm on dobinsons mrr and after a through compression test at uwharrie I'll have about 1/2 gap before bottom out
