SIMAGIC P-RSK Shift Knob

The Simagic P-RSK is compatible with three Simagic shifters: the Q1, Q1s and DS-8X. The standard thread mounting means knob replacement is fast and tool-free — it takes just seconds to completely change the look and ergonomics of your shifter.

Both knobs are made from true carbon fibre and fit the same shifters (Q1, Q1s, DS-8X), but differ in shape. The P-RSK has a round, spherical shape providing symmetrical grip from every angle — ideal for a natural hold from any approach. The P-TSK has a tapered, elongated profile similar to knobs used in motorsport rally cars. The choice comes down to personal ergonomic preference and aesthetic style.

The P-RSK is made from true carbon fibre composite — not a wrap, print or imitation, but genuine woven carbon fibre. This delivers minimal weight combined with exceptional rigidity, providing a precise shift feel and long-term durability under intensive sim racing use. The characteristic carbon weave delivers a professional motorsport aesthetic.

The spherical shape of the P-RSK allows a secure, symmetrical grip from any direction — regardless of which angle the hand approaches during a fast gear change. The palm wraps naturally around the knob, reducing fatigue during long sessions and enabling smooth, precise movements in both H-pattern and sequential modes. This is the classic knob shape used in sports and road racing cars.

No. The Simagic P-RSK is a dedicated accessory designed exclusively for the Simagic Q1, Q1s and DS-8X shifters. Its thread mounting is designed to the standard of these specific models and may not be compatible with third-party shifters. Verify the thread specification before purchasing for use with any other brand's shifter.

Replacing the stock knob with the P-RSK immediately elevates your rig's aesthetics — the characteristic carbon weave pattern delivers a professional, motorsport-grade look. The carbon fibre knob is lighter than plastic alternatives, reducing lever inertia for faster, more responsive gear changes. The round shape provides symmetrical grip from any angle and reduces hand fatigue across extended racing sessions.

No. The P-RSK installs via the standard Simagic threaded mount — unscrew the existing knob and thread on the P-RSK. The swap takes a few seconds and requires no tools or modifications to the shifter. It is one of the simplest and most visually impactful upgrades available for any Simagic sim racing setup.
