This Formula 4x4 leaf spring kit lifts the rear of your BT-50 TFS and RG04 by about 45mm and is rated for a constant load of up to 200kg. That suits the odd load in the tray and weekend camping gear, carried without the rear sagging.
Paired with long-travel shocks, the springs keep the ute level when loaded and steady on corrugations and rough tracks, while still riding well on the road. The kit includes new U-bolts and a SuperPro shackle kit, so the rear is done in one job.
