T-Works YZ series 5.5mm titanium ball studs
Coming from T-Works are new 5.5mm titanium ball studs for the Yokomo YZ-2 and YZ-4 series off-road buggies. The pivot balls are machined from high-quality 64 grade titanium and they are available in sets of two and in 6mm, 8mm, 10mm or 12mm specification – all are direct replacements for the original parts. However, due to being cut from lightweight yet more corrosive-resistant material they scrub both overall weight and unsprung mass.
