Delrin Knobs

Ergonomically Contour. Smooth. Cool. Lightly Weighted. Secksy.

The K20mart Delrin V1 white light bulb shift knob debuted back in 2008 as a word of mouth product that sold through several go-to Honda message forums: NWP4LIFE, K20A.org, and Honda-Tech. The V1 was originally a Karcepts shift knob design offered exclusively to us in a white colorway. We’ve built upon the V1 and offer four additional versions – V2/V3/V4/V5.  The V1 is currently discontinued unless popular demand calls for its return.

Why Delrin?
Its a unique polymer and its properties stays cool and tolerant to the touch when exposed to the sun. It’s smooth, looks cool, and is light weight. It’s more affordable than aluminum or stainless steel.

Available in 4 versions – V2. V3. V4. V5.
V2 is solid Delrin that is pre-tapped with a 10×1.50mm thread pitch only (Honda/Acura).
V3-V5 feature a hollow shell design for pressing in a weighted stainless steel insert.
The insert has optional thread pitches of 10×1.50mm or 10×1.25mm.
V3 insert can be pressed in flush or countersunk.
V4-V5 insert are pressed in flush only.
Colorway options are black or white for all versions.
