New coils or just 5100's

I have a set of 5100's on order and was planing on setting them at 1.75 as my 2010 AC non TSB is sitting 2'' high in the rear. Now, I am thinking about ride quality and wonder for a couple hundred bucks would it be worth it to get a set of new coils? And, which one? I am only looking for about 1.5 inches of lift and dont plan to do anything to the rear. I am running 265/75/16's on stock wheels and like the set up just fine. Mainly looking to level and good quality ride on road/off road.

 

I have 5100's set to 1.75 and TRD off road (stock) coils. The ride is fantastic. Your rear (the trucks) will sag eventually, trust me. You will want at least the rear TSB if you are going to set the 5100's to 1.75. Mine is level with the TSB.

 

I dont have the TRD, just the stock SR5 4x4. Maybe that has something to do with it being 2'' higher in the rear already.

 

Well when I had the TSB springs installed and I had a 2 inch lift my rear still sat higher. So I would say the perfect setup for you, since I have had this as well is just get the 5100s and put a set of eibach coils in there for a 1.6 inch lift. It will sit almost perfectly level and ride nice.

 

Your best bet is 5100's with stock coils or OME coils with OME shocks. But since you already have the 5100's on order, stick with the stock coils. They are practically valved for stock applications.

 

get the billys and try them out. They should be fine since your not maxing them out. If you want more lift later on you can always either put them on a higher setting or add some eibach or OME coils. Non of which are expensive.

 

Ok, if I keep the stock coils, and set at 1.75 do they settle at all?

 

Here are Eibach Coils with 5100s set at .85 and a stock rear (no tsb). It still has about .75 inch of forward rake and the ride is smooth.

 

Any Vibs? I have the same set up sitting here in my house. Still wondering if I should add it? Worried about vibs...on a brand new truck if I add the above components. thoughts?

 

No vibes, it rides real nice and leveled out the truck. The coils only gave about an inch of lift with the 5100s set at zero. I got about 1.75 inches when I bumped the 5100s up to .85.
