Bilstein B12 Aggressive Swamper Lift kit 35mm for T26, T28, T30 - All Questions

Did you add the wrong number and meant WC498T524 and WC498T514

The kit we refer to as 'aggressive' is the one others list as 'extreme'? they're both 35mm lift, but the 'aggressive/extreme' kit has the following benefit?
The kit still contains all the same components as the original 35mm lift kit. Both kits use the same spring set-up and rear dampers. The front dampers, however, offer approximately 25mm further travel. This may not sound like much, but it makes all the difference when tackling the most adverse terrain. The increased travel allows the suspension to remain planted in harsher off-road scenarios meaning you ultimately have greater control over the vehicle when it matters
