Which part number is yours

There is one part number to match, 1364000. The maker also shows SKU 1364020, so the listing you open should carry one of those two numbers. TeraFlex lists the kit for the JT Gladiator pickup with no years or trims, and it does not break the part number out by cab, bed length or trim. Fender type is the one detail that changes the answer, because it sets the tire size: 33 in with Sport or Overland fenders, 35 in with Rubicon or Mojave fenders. The maker also attaches conditions. Longer shocks are required and not included. EcoDiesel models need the 1 in front coil spring spacer kit 1155100, sold separately. Bump stop extensions of 2 in front and 1 in rear are listed for 33 in or 35 in tires. Wheels need 4.75 in backspacing or less, or the offset adapter pair 1057000. Before buying, match the part number, check your engine against the EcoDiesel note, and measure your wheel backspacing.
