Product details

The Extender \ Max exists for a few reasons, we've all been in cars where the reach from the steering wheel to the shifter is just too long for quick shifting. There are also enthusiasts who just like the aesthetic of a tall shifter arm and shift knob. The Extender \ Max is a solution to both of these problems, it gives your shifting experience the look and functionality you want.

We looked around the market and saw nothing but shift knob extenders that look like poorly fitted sticks attached to the shifter arm, with exposed jam nuts and a lack of design. We took the opportunity to use our brains, design prowess and manufacturing skills to create an extender that addressed these issues.

During intense track and autox driving, maintaining consistent control of the steering wheel by having 2 hands on the wheel improves car control and reduces lap times. By decreasing the distance between the steering wheel and shift knob, you reduce your hands travel time between the steering wheel and shift knob keeping your hands on the wheel more.

We're tired of seeing poorly designed shift knob extenders that detract from your car's interior. The Extender was intentionally designed to have a nice, proportional visual relationship between your reverse lockout and shift boot. The satin anodized finish has a premium look while not standing out from your interior. The contrast cut icon provides that subtle touch of detail and marks the design and craftsmanship of Raceseng products.
