Diameter and Weight

This PERRIN Shift Knob comes with a 1.85" diameter and weighs 1 lbs. This diameter is approximately the same diameter as the OEM WRX/STI shift knob.

Height Adjustment and Locking

The PERRIN Shift Knobs height can be adjusted by as much as 1 inch with the built-in adjustment screw. Once the height is set, tighten the lock bolt and your knob will never loosen on its own. Best of all, our super locking mechanism will not harm the threads of your shifter!

Construction

Multi-piece design for easy and accurate installation as well as great looks. The main body is precision machined from heavyweight stainless steel. Gear shifts with the stainless steel shift knob have been described feeling like an accurate bolt action rifle shifting feel. The lower piece is machined from billet aluminum and designed to hold your shift boot up with its lower groove.

Finish

Each PERRIN Shift Knob is precision machined and is finished in blue Cerakote. With this finish being extremely durable, your shift knob will be ready for years of shifting.

"Cerakote is a Polymer-Ceramic Composite coating that can be applied to metals, plastics, polymers and wood. The unique formulation used for Cerakote ceramic coating enhances a number of physical performance properties including abrasion/wear resistance, corrosion resistance, chemical resistance, impact strength, and hardness."
