RN I’m on 32s and open diffs, with 5100s, giving a 3” lift in the front, but no diff drop and I still have the stock UCAs.
I do have a TRD axle and front 7.5” clamshell with a Detroit LSD installed, both with 4.88 gears with about 20,000 miles on them. Would you say it’d be advisable to install these, or would it kill the drivability of the truck? Also would you say a LSD in the ADD front diff would be asking for trouble? It sounds like @Metcalf was saying the guys locking their IFS front had a lot more breakage. In theory the LSD should make the diff stronger, and shouldn’t be as hard on the CVs as a lunchbox locker.
Still, ideally I’d rather just have a rear locker and 32s/33s on the stock gears. I spend a good amount of time on the highway and it’s already howling at 3k rpm at 75 mph on the 4.10s on 32s. I’d appreciate your advice, thanks.
i have 4.88's w/ 285/75-16's. I will argue all day long that 5.29's would have been a better choice. The OD on the Auto is way higher than the OD on the manual... even w/ 5.29's, the cruising RPM's are almost the same as stock 5-speed w/ 4.10's/31.s
