Couldn't load pickup availability
A complete front-to-rear lift package pairing Bilstein's 6112 B60 2.5in big-bore front coilover with a Bilstein Platinum rear shock, matched to a duty-rated leaf spring pack and fresh leaf spring bushes. Choose your vehicle (N70 or N80), your leaf pack duty tier, and optionally add a CalOffroad Fixed Upper Control Arm Kit (2° caster) to correct geometry at ride height.
Dial in front and rear.
A stock front axle sits at 1180kg on a 600lb coil, and a stock rear axle sits around 1000kg on a LD leaf pack. Every kilo you bolt on shifts both numbers — but only the fraction that actually lands on each axle. Tell us what's fitted and we'll work out the rest, front and back.
Please fill in your setup below before ordering — it helps us make sure we build the right spec for your vehicle. Skipping it is fine, but the details help us get it right the first time.
Build this for how you actually drive — the daily commute, the school run, the odd weekend track — not the one loaded trip you do three times a year. Nobody enjoys a daily-driven brick just so it's ready for a trip it takes twice a summer. If your heavy trips are rare, tell us straight and we'll spec for the other 80%.
Lift Height
We only build 2in and 3in kits — see why below.
Selected lift height: ?
Rear Shock Length
Standard fits the factory bump stop. Long travel has a shorter closed length and needs a bump stop extension.
Front-Mounted Accessories
Bull bar and winch hang off the front overhang, so essentially all of that weight loads the front axle.
Underbody & Chassis
Mounted between the axles, so only part of the weight transfers forward.
Rear-Mounted Gear
Tray, canopy, boxes — mounted behind the cab, so this loads mostly onto the rear axle.
Towing
Tow ball weight loads almost straight onto the rear axle.
Recommended Spring Rate
Recommended Leaf Pack
Uses the Vehicle option you picked above — N70 and N80 run different leaf packs and shackles, so getting this right matters. We've set the Leaf Pack Duty Tier option to match — override it up top any time.
Your setup has been calculated and attached to this order — we'll confirm the exact spec before we build.
Guide only. Your answers attach to your order automatically so we see them at checkout, and we'll sanity-check the spec before we build. We're chasing ride comfort and capability together — not stance for its own sake.
What's included
- Bilstein 6112 B60 Front Coilover (2.5in big bore)
- Bilstein Platinum Rear Shock — 630mm open
- Rear leaf spring pack — duty tier selectable, matched to your Vehicle selection (N70 and N80 use different packs)
- Leaf spring bush kit
Note: N70 and N80 shackles differ too — if you're supplying or reusing your own, check fitment against the Vehicle you selected above.
Optional add-on: CalOffroad Fixed Upper Control Arm Kit (2° caster) — corrects caster/camber geometry at this lift height, sold separately or bundled here at a discount off buying individually.
Prices shown are the sum of individually costed components. This is a made-to-order package — allow standard lead time for the leaf pack and 6112 to be picked and freighted together.
