Upgrade and add a bit of color with the GSI "TR-1" Thumb Rotary Knob. Meticulously machined from a solid block of 6061 aluminum, each knob boasts unparalleled durability and precise engineering, ensuring smooth, flawless rotations every time you use it. Available in a variety of anodized colors, this knob adds a dash of personalization and character to your steering wheel.

How to Install

  1. Find the screw holes on the rotary knobs currently installed to your wheel and use a 1.5MM HEX bit to loosen (but not remove) the grub screw. Each new rotary knob already has a grub screw pre-installed.
  2. Place the new rotary knobs on your wheel and tighten with the 1.5MM HEX bit (do not over-tighten to avoid damaging the knob and rotary post). 
  3. You're done, enjoy your new wheel look!

*Fits on FPE V2, GXL V2 and Interlock.

Madison V. ★★★★★

The machining on this thing is genuinely impressive — you can feel the difference from the stock knob the second you grip it. The aluminum has a nice weight without being bulky, and the color pop on my dash is exactly what I was after.

Olivia Q. ★★★★★

Swapped the plastic knob on my radio for this and the difference is night and day. The 6061 aluminum has a nice heft to it, and the machining is clean with no sharp edges. Feels like it'll outlast the radio itself.

Abigail N. ★★★★★

The knurling on this thing is perfect, way grippier than the plastic knob it replaced. Machined from one solid piece of aluminum too, so it feels like it'll outlast the tool. Takes about two minutes to swap and the little pop of color is a nice bonus.
