yes, I used a thick turnbuckle for added support onthe front chassis brace....good eye on you.
The upper alluminum shock caps are off a Lightning Buggy. The lower shock ends, I just switched out to aluminum ones that my LHS carried for a MGT, sorry no part number on that.
The diff oil, I did not change that yet as my racing season had ended with only 2 races on the truggy. The shock oils, I used 35wt.
Another thing that I swapped due to factory production defect was the front universals since the pins that sit in the diff cups will snap off on the Pro on non Pro versions. For now, I traded a fellow truggy owner for his rear dogbones and I used them on my front drive axles until HB or MIP provides stronger replacements. The rear dogbones don't have issues. However I did hear that a CVD from a LST is long enough for the HB truggy. I have tried a CVD from a MGT which does come close but a bit too short when it comes to suspenion travel which they may seem to fall out of the diff cups.
Not much other changes done until hop ups and stock replacements are available. If your LHS carries Lightning buggy parts then that's a good thing since alot of parts work on the truggy.
Good luck with yours.
