Caliper render for this kit:
At around 2,100 kg kerb, before a trailer, roof tent or recovery load is factored in, the JT Gladiator asks more of its front brakes than almost any other vehicle at this price point. The factory stoppers handle light use without drama, but load the truck to its rated payload and thread it down a long switchback descent, or ask it to repeat-stop hard on a track day, and the thermal limits of the standard setup become apparent in short order.
The XYZ Racing front big brake kit for the Jeep Gladiator (JT) covers the full 2020-2026 production run and comes in three pad compounds to match how hard you run the truck. A full caliper finish range gives owners control over how the hardware presents behind the JT’s wide alloys.
What this brake kit does for your 2020-2026 Jeep Gladiator (JT)
The two-piece floating disc accelerates airflow through the rotor under rotation, directly reducing surface temperatures during sustained braking, the kind the Gladiator encounters on long descents or under towing load. The JT’s solid Dana 44 front axle concentrates a disproportionate share of deceleration force at the front end; the enlarged disc and higher-clamping caliper spread that force across a greater swept area, pushing fade onset further away. The floating bell lets the rotor expand evenly and stay flat, and braided lines firm the pedal for predictable feel under load.
Three compounds span the use spectrum. Street is the quiet, low-dust default for mixed road use. Sport adds bite and a wider heat range for owners who regularly tow at or near the JT’s 3,500 kg rated capacity. Racing is the dedicated track and competition compound for temperatures beyond the Sport pad’s working range. You select the compound when you order.
About the front big brake kit
The kit pairs a hollow-body forged caliper as standard with a two-piece floating disc whose hollow-vane geometry draws air through the disc’s internal channels during rotation, maximising the volume of cooling air passing through the rotor core, a measurable gain when the vehicle regularly exceeds two tonnes and sees sustained, repeated heat cycles. Discs are offered drilled or slotted at the same price, and centre bell upgrades come as two-tone anodizing in five colours, or titanium, selectable at checkout.
Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. A Custom Color in any Pantone is £150. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, with a premium candy range of Candy Teal, Candy Blue, Candy Red and Candy Orange. For competition and heavy off-road use, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C and carries a two-year warranty.
Fitment for the Jeep Gladiator (JT) (2020-2026)
This listing covers the Jeep Gladiator JT platform across the full 2020-2026 model year span. The JT runs a solid Dana 44 front axle throughout the range. Confirm your wheel offset and any suspension lift specification before ordering, as wheel clearance around larger rotors is lift-dependent and varies by rim width. No other Jeep platform or year range is covered by this listing.

Choosing your spec
Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.
Brake pads — Street, Sport or Racing
Every kit ships with a full set of high-performance pads; the compound is your call.
Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.
Caliper grade — Hollow vs Hollow Racing
Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.
Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.
Caliper colour & finish
Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).
Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.
Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).
Centre bells
The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
