Product Description

The Skunk2 Short-Throw Shift Adapter (628-05-0300) is a precision CNC-machined, high-strength steel alloy shift adapter designed specifically for the 2006-2008 Honda Civic Si Coupe and Sedan. By repositioning the shift pivot point, it reduces shift throws by more than 20% - delivering shorter, crisper gate-to-gate transitions without sacrificing smoothness or daily drivability. Unlike aluminum alternatives that are prone to failure under repeated stress, Skunk2's steel construction ensures long-term durability in both street and competition environments.

Installation requires only basic hand tools and no permanent modifications to the OEM shifter assembly, making it one of the most accessible performance upgrades available for the FA5/FD2 Civic Si platform. This adapter is not compatible with 2009 and later Civic Si models due to a revised shift linkage design introduced with the facelift. For Si owners looking to complement the upgrade, Skunk2 recommends pairing with a Skunk2 shift knob for a complete, refined shifting experience.
