Drive Shaft Shop Jeep Trackhawk WK2 3" Aluminum 1-Piece Front Shaft
The Drive Shaft Shop 3" Aluminum 1-Piece Front Shaft is a robust upgrade for 2018+ Jeep Grand Cherokee Trackhawk WK2 models, built to manage torque up to 1,200 HP while slashing weight and vibrations for sharper acceleration and stability. Fabricated from high-strength 6061-T6 aluminum tubing with balanced 1350-series U-joints for reliable power delivery, this single-piece design overcomes OEM limitations by eliminating support bearings and flex. As a direct bolt-on replacement, it sharpens throttle response, boosts traction, and endures punishing conditions, essential for Hellcat-powered Jeeps in drag strips, rock crawling, or highway hauls demanding unyielding driveline performance.
