Tough Dog raised front coil springs for the Jeep Wrangler JK (March 2007 - 2018), approximately 40mm of lift, sold per pair. Pick the part for your wheelbase, engine and front-end weight using the application guide below - several combinations share a spring rate.
Tough Dog coils are designed and made in Australia from micro-alloyed spring steel – shot-peened, scragged and load-tested, and hot-formed on precision mandrels so the spring keeps its height and rate after years of heavy loading.
Pick the rate for the weight the vehicle actually carries, not the weight you'd like it to carry – and count only permanent accessories and loads (bar, winch, drawers, long-range tank) when choosing. A spring that's too firm for an unloaded vehicle rides worse than the factory item; one that's too soft sags the moment you load up.
Fit springs in pairs per axle, and book a wheel alignment after any change in ride height. It's also worth checking brake-line slack and bump-stop condition while the suspension is apart.

These suit the following applications: Jeep Wrangler JK (SWB & LWB) March 2007 - 2018. Check your build date and variant against the fitment table on this page – if you're not certain, contact us with your rego or VIN details and we'll confirm fitment before you order.
The listed price covers both sides – always replace left and right together so the axle is evenly damped and sprung. It's a bolt-in job for a competent home mechanic or any workshop; check bushes, mounts and brake-line slack while everything is apart.
A moderate suspension lift is generally acceptable in most Australian states, but the allowed total lift and whether certification is needed differ between states and change over time – so always confirm with your state’s transport authority before modifying. Our guide explains how the rules work state by state: are lift kits legal in Australia?
