2005 tacoma

Just bought a 2005 Tacoma trd with a toy tech 3 inch with boss shocks it was installed at the dealer 40,000 km ago. The shocks are leaking oil and the truck rides like a old lumber wagon it has front diff drop brackets and sway bar link drop and looks like he has them adjusted up maybe a 1.5 inch to 2 inch from factory. I bought complete set of struts and springs from a 16 Tacoma limited that was pulled with 500km on it. I no they set a inch higher than the 05 stock does. My question is I dont want to change the factory ride much and this truck won't be used off road just a little logging road cruising. I only need probley 1 to 2 inch block. Alot of these formula says the bilestien 5100 adjustables are the way to go. But will 1-2 inch block on top of the spring change the ride that much????
