Radflo Advice

2020 TRD sport 4x4 owner here


My local shop is suggesting I throw Radflo 2.5 with RR and compression adjusters all around. Front and rear should be around 2500 for parts.

I’m looking for an OEM+ look. So a level up front of ~3in with rear suspension at stock height.
My goal is to stuff 35s with my stock TRD sport wheels.

35x12.5xr20
285x65x20

will I need UCAs with this set up? I’m hoping to avoid a BMC, but wouldn’t be opposed to it if necessary.

95% on Road
5% off road (more than just fire roads: mild rock crawling and Ruts) SoCal users think Cleghorn and Gold Mountain

 

Ive heard good things about Radflow. If you go 3" up front you will be nose high. I'd recommend atleast 1" lift out back. For true 35's your likely going to need a BMC. An Yes you should get UCA to do it right..

 

For a 3in lift up front I do suggest replacing your UCA for alignment.

Running 35’s you’ll definitely need to do a BMC and you’ll have rubbing issues on the inner fender liners of the front bumper. You may want to look into front bumper shims to bring out a 1/2in+ more unless you don’t mind cutting your fender liners.

If you’re going to stick to slower driving on fire roads or slow mild rock climbing you really don’t need compression/rebound adjustable shocks. You’ll only feel the difference when off-roading at higher speeds. You can also get away with just a coil over setup without an external reservoir if you wanted. I’d make sure that the shock you use can be rebuilt because you’ll need to eventually do that in the far future.

For the rear at least get a 2.5 shock. For lift you can keep the stock leaf springs and increase height with just replacing your rear shackles.

You can also look into using an Add-A-Leaf pack in which you wouldn’t need new shackles but replaces some of the leafs in your current pack. The benefits of a AAL is increasing ride height at same time increasing or fine tuning your rear load capacity in the bed or softer for higher speed off-roading which looks like you won’t be doing.

now with all this being said, make sure that this is what you know will be the purpose of your truck because if you change you mind quickly you’ll end up spending more money on changing your suspension again. This is when people will tell you, “buy once, cry once”. Meaning spend more on a nicer suspension set up now and you’ll be able to do more with your suspension and truck down the road.
