anyone have the part numbers for 1 ton calipers and rotors? i think this is the route i want to go for a brake up grade. what models did these parts originally go on?
Well... Depends. There were a few 4x4 1 tons I think, so they'd be 6 lug. But if you're a 5 lugger, I think you're only reference-model would be Toyota RVs or those old U-haul duallys (even though the 1-ton duallys had bolt on adapters that utilized a different bolt-pattern) I scoured rock-auto and such and think I only found a few rotor sets... I'm at a loss, man.
The 1 ton cab and chassis came with 6 lug wheels (2WD). They have a different lug pattern than the 6 lug 4WD. The two are not interchangeable. You would have to get spindles,hub assemblies and rotors to make the swap along with the correct 6 lug wheels. They wouldn’t match anything else on your truck. The cost vs benefit would not be worth it. Best to stay with what you have.
The 4runner caliper swap has be done many times by members in this forum. I did forget to mention though, they used aftermarket rotors. Wether they were OE replacements to something else or willwood producrs
The 4runner/v6 front brakes and rear disc swaps are very common upgrades for older 6-lug Toyota pickups to get more stopping power. I believe the same upgrade similarly applies to the 5lug trucks
