replacing trd sport suspension

Looking for any ideas for replacing original stock suspension. I do pull some trailors and was thinking about installing some air bags with the new rear end. maybe a small lift? open to all ideas. Truck has 180000 kms and is well maintained.
What about boosting the horse power? K&N air filter system?

 

I see you have a DCLB , so do I , I went with an OME lift , 885 coils and Dakar leafs

2 1/2" lift front and rear and awesome for loads

 

Also , Welcome to TW

 

Like OZ said, the OME lift is a great lift. Those dakars are a good all around leaf pack.

As for boosting HP, the only good option is the TRD supercharger. The factory intake is already a cold air intake so any gains from changing it out are extremely small. Doing lots of little mods, like light weight pulleys, headers, y-pipe, cat-back, intake, maf cal, etc will start to add up, but in the end the TRD S/C will make more power than all of them combined and doesn't cost much more than all of those mods combined.

 

Thanks for the hospitality, and the ideas. Did your lift come as a package? I also have noticed a whining in my engine. Definetely not power steering. How do I check the timing belt?

 

The 4.0 engines do not have a timing belt, it has a chain. I would check the idler pulleys, belt tensioner, and belt first they can make some noise and are often the problem, also welcome to TW...

 

Hey oz where did you get your lift from? And what did you end up paying for it up here? I wanna lift mine a bit but I don't want to go to big and have to start hanging everything out. How big can I high can I go before I need to start changing out everything? I was thinking 2 1/2 to 4 inch

 

I got the OME stuff at Cap-it and my LR UCA's from Toytec , around $2000 all in IIRC

 

If you are in the Calgary area I ordered mine through Kyle at Cochrane Toyota.

 

Also check out OUIPACK for OME stuff in Canada , I didn't know about them till after I bought my kit
