Updated Delrin 5.0mm Lower Arm Ball Cups for RC MAKER SP1 and SP1-F.
These ball cups that connect lower suspension arms to hubs and chassis.
Manufactured from Injection Moulded POM Delrin Material. This material is harder and also tuned for a finer tolerance. This removes both play and friction from the lower arms. The Outer diameter and tolerance on these is very slightly different (0.02-0.03mm) to the original 3026, so please take note that the holes in the carbon may need fine adjustment for cars from Batch 1, 2 and also the -2mm Arm Conversions. Holes in future kit batches and -2mm arm conversions will be updated to fit these new 3026A Ball Cups.
