🧾 Overview
The TeraFlex Exhaust Spacer Kit is a required upgrade for 2012–2018 Jeep Wrangler JK and JK Unlimited models running 2.5 inches or more of suspension lift. When lifted, these vehicles can experience contact between the front driveshaft and the exhaust crossover pipe during suspension droop—this kit corrects that issue to prevent damage and noise.
By relocating the exhaust crossover pipe rearward, the TeraFlex Exhaust Spacer Kit restores proper driveshaft clearance throughout the suspension’s range of motion. Designed as a simple bolt-on solution, it installs between the exhaust header flanges and crossover pipe flanges using the included extensions and hardware.
