Build the kit around how you actually drive.
Answer a handful of questions about the vehicle, how it's loaded and where it goes. We work the weight onto each axle, then call a package, spring rates and the supporting parts that lift actually needs — the same conversation you'd have in the shop, before you order.
Spec it for the driving you actually do — the commute, the school run, the odd weekend away — not the one big loaded trip you do twice a year. Nobody enjoys a daily-driven brick that's permanently set up for a trip it rarely takes. If the heavy stuff is rare, tell us straight and we'll build for the other 80%.
The vehicle
Platform sets the stock axle weights, the front end type and which packages we build for it.
How it's used
This is what decides the package character — comfort-biased, load-biased or built for speed on the rough stuff.
Front of the vehicle
Bar and winch hang off the front overhang — essentially all of that weight lands on the front axle.
Back of the vehicle
Tray, canopy, drawers, water — mounted behind the cab, so this loads mostly onto the rear axle and sets the spring rating.
How the recommendation is worked out
The same logic we'd run through in the shop, made explicit. It's a guide — the final spec is always confirmed against the vehicle before anything is built.
Axle loads
Each accessory has an average weight and a split between the axles based on where it sits. Front-mounted gear (bar, winch, lights) loads the front almost entirely; underbody gear is shared; anything behind the cab loads the rear, with a small amount carrying forward. Tow ball download is added straight to the rear.
Spring rating
- Front — starts at the platform's stock rate and climbs with the weight added over the front axle. On Hilux we quote it as a coil rate in lb; on other platforms as a duty band.
- Rear — leaf platforms get a duty tier (LD / MD / HD / XHD) from the added rear weight; coil-rear platforms get a rate band plus an adjustable panhard to re-centre the axle at lift.
Package
Your primary use, top priority and terrain build a profile across five traits — road manners, off-road control, load capacity, value and competition-grade damping. Each package we build for the platform is scored against that profile and the best fit is called, with price breaking any tie.
Supporting parts
Driven by front-end type and lift height: independent front ends at 2in+ need upper control arms and a diff drop to correct geometry and CV angles; live-axle fronts need caster correction; coil-rear needs a panhard. Big tyres and hard off-road use add bracing. Extended brake lines come in at 3in, or at the rear on 2in.
Indicative stock figures used

Averages and platform figures are working numbers we refine as we build more of these. Cubby House Fabworks confirms actual weigh-bridge figures and current pricing before building.
