The 3.42 would be a all around street gear, good for pulling or highway driving. I swapped my 3.42 for a 3.08 because of the 6 cyl rpm range and I like to drive 65 and 70. I did have to change the spring perches because the '37 uses a 1 3/4" wide spring. Your newer truck should use the same 2" spring, so you still may have to relocate them inward or outward. Joe | | |
