PERRIN Shift Knobs come in two different sizes. A Small Knob (1.6" diameter, 0.7 lbs.) and a Large Knob (1.85" diameter, 1 lbs.) for power shifters. The Large Knob is approximately the same diameter as the OEM WRX/STI shift knob.

• *Height Adjustment & 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 raw brushed stainless steel. With this finish being extremely durable, your shift knob will be ready for years of shifting.
