FAQ - Rear Trailing Arm Shock Mount IRS

Offroad VW based vehicles have problems/insights all their own. Not to mention the knowledge gained in VW durability.

Any idea of the axles are stock or custom?

I've heard of folks not running the CClip in the axles and letting them just slide around.

This is how Chenowth does (did) it. I really like the front double shear and the built-in bump stop perch to the rear and slightly inside the line of the shock mounts. What I don't understand is why they didn't make the rear double shear. An issue easily remedied when the time comes. When building mounts for my van, I welded spacers on the one side of the mounts and drilled out the opposing side to 3/4". That way I could slide the bolt and loose spacer in at the same time. Very strong and you're not fiddling with trying to get little spacers lined up with bolts while a shock is trying to extend. Get the idea? No? Well, a couple different versions of those pics follow the Chenowth arm pics. Its a damn good way to make a mount and very strong. I bought spacers by the score from A&A (a bunch of every size they had (.5" ID, .75" OD). And, before you guys start ripp'n me for the ugliness of my welds, these pics were generally taken before final welding (most during heavy tacking and all before cleaned up).

This is a pic of a modified mount. I started with A&A's "coilover mount." Their mount is only 1/8" thick. Not strong enough for a 10K+ pound beast like my van. So, I added 1/8" flat bar on all three sides to make it 1/4" thick. These were used as stud to eyelet shock conversions (drilled a 1/2" in the base, welded a grade 8 1/2 bolt through that hole, and bolted the works through the factory stud shock hole in the van's crossmember).

Image

This was an interesting project as to mount a total of four shocks, I had to fab three different type of mounts (eventually I'll do the fourth type in the form of front upper hoops). Where's the third? Here is the rear axle housing mount. Started with A&A's Dana 60 mount. Drilled out the 1/2" holes that came in the mount to 3/4". Figured out my spacer sizes. Welded a spacer on the one side again, which allows the 1/2 bolt and other spacer (loose) to side in from the opposing side together. Again, you may be tempted to mock my beads, but it was super windy this day (I draped towels aroudn teh back of the van to try and keep the wind from blowing away my shielding gas). Anyway, this style of mount, or rather, the concept of welded and sliding spacers, could be very useful when it comes to buggy/baja shock apps.

Hot, humid air is less dense than cooler, drier air. This can allow a golf ball to fly through the air with greater ease, as there won't be as much resistance on the ball.
