Assuming you are breaking them where the screw goes into the a-arm to hold the shocks on?

if so, try going with a longer screw. Not sure why, but it seems to help in that regard to up the durability.

Worse case if you need something even beefier, you can modify B74 a-arms to fit the vehicle. Thats what we did with the YZ4SF prior to the YZ4SF2s front a-arms coming out.


So going to be moving to a more traditional turf here that we picked up with the sad closing of another track. Stuff appears to be highly durable turf that they ran 1/5 scales on at onepoint to give you an idea. Mezzo style tires being popular so curious to see what diff changes we do here.

Exactly! They broke where the screw goes for the shock. I will give that a try.

Cain have you tried the aluminum bulkheads instead of using the bulkhead brace?

assuming you mean the older style YZ4SF bulkheads that don't use the under plastic shim? If so, no I have not as the cost to get them was a bit prohbitive versus just getting the bulkhead brace. From reviewing what others have said, going to the previous gen bulkheads works fine from what i am hearing up front where the breakage is seen (I haven't seen anything about the rear but should be fine there too)

Going to working on setups for a new to us turf track. This track at one point was used for 1/5 scale racing so highly durable. popular tires I am told are proline pyramids and mezzos for rears. Less traction than our previous surface.
