Weld-In Steel Bushing for Raptor Joint 2.5'' Uniball – 1'' Thread
A threaded steel bushing to be welded into the arm tube, made for the Raptor Joint 2.5'' uniball end (RAP-RPRJ9113). It stands 57 mm tall, has a stepped 31.7 / 41.7 mm outside diameter and a 1'' right-hand thread. This is the part that turns a plain tube into an arm with an adjustable end.
Weld-In Steel Bushing for Raptor Joint 2.5'' Uniball – 1'' Thread
A uniball end has nothing to hold on to unless the arm has a threaded socket. This bushing is that socket – you weld it into the tube, and only then can the joint be screwed in and the arm length adjusted.
It is made for one specific size: the Raptor Joint 2.5'' end, part RAP-RPRJ9113, with its 1'' right-hand thread. The stepped outside diameter makes it easier to seat and align the bushing in the tube before welding.
Thread 1'' right hand | Height 57 mm | Outside dia. 31.7 / 41.7 mm |
Key benefits
- A ready-made threaded socket – no need to turn your own insert or improvise with nuts; you weld in a part with known dimensions.
- Stepped diameter – 31.7 mm and 41.7 mm give the bushing a natural seat in the tube and help with alignment before welding.
- Matched to one specific end – the 1'' right-hand thread matches the shank of the Raptor Joint 2.5'' uniball, so there is no room for a mismatch.
- Steel construction – designed to be welded, that is, to become a permanent part of the arm.

Installation notes
The bushing is welded into the arm tube – a job for someone with a welder who can keep everything concentric, because the whole arm depends on it. Mind the thread direction: 1'' right hand. If you are building an arm adjustable at both ends, the opposite end is usually left-hand threaded so you can change the length without disconnecting the joints.
Why it is worth it
- A straightforward way to turn plain tube into an arm with an adjustable end.
- Dimensions stated outright, so no guesswork when ordering.
- A genuine Raptor 4x4 part matched to the 2.5'' uniball.
