2nd gen suspension swap

Hello members!
I have questions hopefully your experiences and expertise help me out. I have 2015 TRD SPORTS DCLB with 148k KMs mostly highway’s. I just noticed both my LEAF SPRING are sagging. Right now I have 2” leveling kit front and back.
I found a set’s of 2020 TRD OR take out’s local to me. Question is would it fit and any pros and cons? TIA

 

It will fit fine. I think I’ve read that the sport coil springs are firmer than the offroads so the ride might be alittle bit softer on trails

 

3rd gen coils will make the truck ride 1in higher up front compared to 2nd gen coils, so take that into consideration if you have something like a spacer lift.

Rear leafs are going to be essentially the same just less used and will bolt right up. I recommend to get rid of any spacer / block lift.

 

Yes I have front spacer lift and block lift at the back

 

Is there a particular reason why to het rid of the spacer/ block lift?

 

I mostly do highway driving, wanted to do occasional off roading

 

current 2in spacer lift is going to put you arguably up too tall with the coils of the 3rd gen, also inherent issues with spacer lifts up front and the potential to bottom out shocks before bumpstop.

In the rear you create more axle wrap with blocks which can be harder on the driveline and leaf springs.

 

Thank you for all the information, appreciate it!
