Offroad & Truck Big Brake Kits

The Big Brake Kit The Industry Forgot To Build

They've been told the same lie for twenty years: if you want a real brake kit, buy bigger wheels. The whole industry built a category that quietly excluded every serious truck on the road. Brembo starts at 19 inches. AP Racing starts at 19 inches. Alcon, Wilwood — same story. And meanwhile, the trucks that actually need brakes — the RAMs, the F-150s, the LandCruisers, the Patrols, the G-Classes, the Hiluxes, the Prados — are all riding on 17s and 18s because that's what real offroad tyres demand. Two tonnes of loaded vehicle. A steep descent. A trailer behind it. And factory pads cooking themselves into glass on the way down.

That's not a product gap. That's a category nobody had the guts to build.

So SET built it. TX7 fits inside a 17. TX8 fits inside an 18. No compromise on the caliper, no compromise on the rotor, no compromise on you swapping out the wheels you actually need. These are the only big brake kits in the world that respect what you drive.

If you spent real money on a serious truck, you already know. Serious trucks deserve serious brakes. Everything else is just decoration.

Why Every Other BBK Won't Fit Your Truck

Offroad and heavy-truck owners run 17-inch and 18-inch wheels for three reasons: bigger sidewalls absorb rocks and potholes, taller tyre profiles give real flex on uneven terrain, and smaller rims are cheaper to replace when you bend one on a trail. It's a setup that works. Until you go to upgrade your brakes.

Traditional 6-piston and 8-piston calipers were designed around one assumption — that the owner would be running 19"+ track-style wheels. Their bodies are wider, their mounts sit further out, and the minimum rotor diameter they accept won't clear anything smaller than 19 inches of wheel. Fit one inside a 17 or 18 and the caliper physically contacts the spoke.

SET re-engineered the geometry from the inside out. The TX7's 6082-T6 forged body was laid out specifically to slip inside a 17-inch wheel while still clamping a 332mm rotor. The TX8 does the same trick one size up — it packs 148cm² of pad area inside an 18-inch envelope using a custom 355mm D83 rotor. Same stopping force. Different real world.

Vehicle Fitment

The TX7 and TX8 were engineered for the heavy, hard-working end of the 4WD and truck world. If you're not sure which kit fits your rig, contact our team with your vehicle year, model, and wheel size — we'll confirm fitment and recommend the right variant.

Why SET

The Physical Truth

Lift one in your hand and the weight tells you everything — 6082-T6 forged aluminium, 148cm² of pad biting into the disc, a 6 or 8-piston differential bore that grips like a closed fist. Press the pedal and the truck doesn't slow down. It obeys.

Built To Be Trusted

Built to hold 180°C continuous heat, then asked to do it again on the next descent, with a full load, in the wrong weather. The kit ships complete — caliper, disc, pads, lines, brackets, hardware — because trust shouldn't have a missing piece.

Made For Owners Who Actually Use Their Rigs

This is the brake the people who actually use their rigs reach for — the ones who plan trips around terrain instead of fuel stops. You won't see it on a mall-crawler. You'll see it on the trucks parked at the trailhead long before sunrise.

A Statement, Not A Mod

The only big brake kit in the world that fits a 17 or 18-inch offroad wheel. Bolting it on isn't a modification — it's a statement that you took the rig seriously enough to engineer the one part most owners never think to upgrade.

The Freedom Your Truck Was Built For

Your truck was built to go where the road ends. The TX7 and TX8 give you the stopping power to actually take it there — fully loaded, fully committed, fully alive — and bring it back when you're done.

Frequently Asked Questions

Will a SET brake kit actually fit my 17-inch wheels?

The TX7 with a 332×32mm rotor is specifically engineered to fit inside 17-inch wheels with standard offroad spoke patterns. If you're running aftermarket wheels, send us a photo or the wheel spec and we'll confirm caliper-to-spoke clearance before you order.

Can I install a TX8 on my RAM 1500?

Yes. The TX8 is the recommended kit for RAM 1500, 2500, and 3500 with either 410mm discs for 20-21" wheels, or our custom 355mm D83 configuration that fits inside 18-inch wheels while still delivering the full 148cm² pad area. Confirm your wheel size when you order.

What's the real difference between TX7 and TX8?

The TX7 is a 6-piston caliper with up to 110cm² of pad area — ideal for mid-weight 4WDs and utes (1.8–2.3 tonnes). The TX8 is an 8-piston caliper with up to 148cm² of pad area — built for the heaviest trucks and SUVs (2.3+ tonnes, towing, heavy cargo). If your vehicle weighs more than 2.5 tonnes loaded, go TX8.

Do I need to upgrade to larger wheels?

No. That's the whole point. Both kits were designed to fit existing offroad and truck wheel sizes without forcing you into an expensive wheel swap.

Does this work with my factory ABS and traction control?

Yes. SET brake kits are direct bolt-on upgrades that work with all factory ABS, ESC, and traction control systems. No recalibration required. No warning lights. Nothing to unplug.
