Well I'm back, after a lot of research and dealing with both local Toyota dealers I'm no closer to knowing what front coil springs came on my truck. One dealer says 48131-af170, right, 48131-af180, left. The other dealer says 48131-af090, right (yellow/yellow) and 48131- af100, left (yellow/blue). one says my shocks would be 48510-a9450, the other place says my shock's are 48510-09760. neither says that they will lower my front back down. Anyone got a 2004 limited access cab, hell any first gen limited access cab will probably work with you original front spring? If so and you are able to see the color codes on them please let me know the colors. I talked to a retired Toyota mechanic that's my brothers neighbor, he said that most of the 1st gens came with the front drop no matter what package they came with, 2wd, 4wd, sr5, TDR, or off road pkg. So I'm thinking ether one of these coil will work but I don't want to buy then just to find out they didn't make a difference.
