Mechanical DIY Parts – aluminium components for building a sim racing steering wheel

The Mechanical subcategory brings together all the aluminium and mechanical components needed to build or upgrade your own sim racing steering wheel. You'll find knobs compatible with popular encoders and funky switches, professional paddle shifter mechanisms and precision Hall sensor clutches — everything that gives a DIY steering wheel its physical form and ergonomics.

Aluminium knobs for encoders and switches

Aluminium knobs are caps fitted over the shafts of rotary encoders and funky switches, providing a comfortable grip and a professional look. Simline carries several variants to suit different component types:

• Aluminium knob No.1 – classic, compact profile
• Aluminium knob No.2 – slightly wider for an improved grip
• Aluminium knob No.3 – taller variant with a knurled surface
• Aluminium knob No.5 – wide, flat profile for encoders with a prominent design
• Knob for Funky Switch ALPS – designed specifically for the shaft of the ALPS RKJXT1F42001 switch
• Knob for Funky Switch – standard aluminium cap for funky switches
• GT NEO aluminium knobs – dedicated knobs for the Simagic GT NEO steering wheel

Paddle shifter mechanisms and clutches

For builders creating fully equipped steering wheels with paddles and clutches, Simline offers precision aluminium mechanisms:

• Aluminium gear shifters – complete paddle mechanisms for mounting in a DIY steering wheel
• Push-pull shifter – an alternative gear change mechanism operating on a push-and-pull principle, popular in rally and F1-style steering wheels
• Aluminium clutches with Hall sensor – precision contactless clutches based on magnetic Hall sensor technology, delivering a linear response with no mechanical wear
