TeraFlex JT: Rear Lift Coil Springs are perfectly engineered for your JT Jeep Gladiator. Out back, we chose progressive triple-rate lift coil springs that provide optimal performance both on and off road as well as while towing. TeraFlex JT: Rear Lift Coil Springs are perfectly engineered for your JT Jeep Gladiator. Our engineers focused on extensive rate tuning and dynamic balance between front and rear and side-to-side load bias to produce Lift Coil Springs that deliver unsurpassed highway handling and off-road performance. Out back we chose progressive triple-rate lift coil springs that provide optimal performance both on and off road as well as while towing. These progressive triple-rate coil springs provide consistent performance and predictable handling throughout normal street driving ? just like a linear rate spring. When the axle begins to droop the softer sprung upper section of the coil spring begins to unwind for maximum flex and spring retention. The stiffer sprung lower section of the coil provides stability while towing. Additionally we lowered the towing coils to improve ride quality while unladen. We recommend pairing TeraFlex Lift Coil Springs with Falcon Performance Shocks for superior performance. TeraFlex coil springs and Falcon shock absorbers have been engineered together to improve both compression and rebound for optimal vehicle stability.

Work as well as the NGK's
Bought for a 2016 Mazda 6, I had NGK's in it for 5 months and had misfires, didnt have the money to throw more NGK's at it for troubleshooting. Bought these to try and they work great so far.

Faulty plug? Otherwise great set
Definitely better than the old plugs that probably had 80k miles on them. The one star off is because I had a misfire after installing. Not sure if I damaged the plug or what, but a reinstall didn't fix the misfire. In my genius, I rushed to try to gap it and ended up breaking the iridium tip. Put the old plug into cylinder 3 (where the misfire was) and it was fine. Gonna have to get a new single tomorrow at my local shop, but a bit frustrating to get a misfire after install.

Upgrade from OEM
After seeing a quite ludicrous $403 quote to change 4 spark plugs in a Mazda3 I decided to show my son how easy it is. These were an upgrade from OEM parts. They were gapped perfectly for the car. They took 20mins to fit and work fine.

garbage spark plugs
misfired after 30 minutes of driving cylinder 4 misfire code, left me stranded on the highway with baby in car. “(9621)” at the end of description is a lie, was not compatible with my vehicle even with compatibility test.
