not sure if they are hartge springs ,just had hartge body kit when i brought it ,and lowered springs ,has always handled pretty good ,very fast around corners .
starting to get a little bit twitchy ,rear shocks(munroe GT ) starting to leak ,and front ones (unknown brand at this stage) run out of travel .
hopefully these will work better than my million mile ones.
brent .
