EAGLE-EYED readers may have spotted the rear wheel’s track aligns perfectly with the front. While that might not normally sound like something worth writing about, it slipped Toyota’s mind when they developed the current 7X platform. Shane’s Jmacx coil conversion didn’t just change out the leaf springs for a set of coils, the upgrade also bumped the rear track width out to meet the front with an upgraded wider axle that avoids complicated spacers or mismatched wheels. The kit also includes stronger rear axle shafts and a heavy duty sway bar. It also added 600kg to the GVM, taking it from 3300kg to 3900kg. The 7X platform is quickly becoming the Swiss Army knife of Australian 4x4s, with upgrades for just about everything you could imagine. However, the Jmacx coil conversion kit takes things to a whole new level!
