Yokomo YOKRP-101SH Titanium Ball End for 4.8 S-Size Linkages  [YOKRP-101SH]

High-strength S-size ball end

The Yokomo YOKRP-101SH is a purpose-built ball end for 4.8 S-size linkages, offering an 11.5mm ball length in a titanium construction that reduces weight while maintaining load resistance. It suits compact steering and suspension linkage setups where S-size fittings are used.

Used as the terminal between linkage rods or turnbuckles and ball studs, this ball end connects servo horns, suspension arms, and bulkheads. The titanium body helps prevent deformation under common model stresses and supports consistent geometry through repeated use.

To fit, screw the ball end onto compatible S-size rod threads until firm, then press the ball onto the mating stud ensuring full engagement without excess preload. Check articulation through the intended motion range and verify tightness after an initial run session.

When tuning, this compact, low-mass terminal helps preserve handling precision; small variations in length will alter throw and toe link geometry, so make incremental changes and evaluate handling before committing to setup changes.
