Had this mod for a while now(perhaps 1.5 years) but for reasons listed below I've barely ever used it. It is a good mod, gives nice suspension lift over default in game offroad parts, yet as of the version I am reviewing it is still a 3 star.
It's a 3 star because of parts limitation. For example: When using it on say the "Heavy Duty Crew Cab Frame" I can only select "4.10 Locking Rear Differential". Also cannot use any driveshaft other then just "Rear Driveshaft". I find the driveshaft breaking more then other lower trucks I have because with said trucks I am able to use "Offroad Driveshaft" as well as addon driveshafts.
Other more minor things as far as I'm concerned is the inability to change the rear shocks, and springs to anything other then LKS. It kinda makes some sense but it's also too limiting.
This mod would be an easy 5 star if those things where addressed. Honestly might be 5 if just the rear driveshaft, and Differential issue where addressed(I'd be happy to go with 4 if only an offroad rear driveshaft where added, or compatibility with all driveshafts default and mod).
Sooo yep, Good mod, bit it would seem it is a bit lacking in some crucial areas.
