BDS 2.5” Coilover Trailboss/AT4

Trailboss75 · January 22, 2020

Just saw this on Instagram. BDS announced a new 2,5” coilover lift for the Trailboss. I was pretty excited until I saw the price.

tboughts? Seems to me it’s same price if you bought the 4” lift and bought coil overs separately. This doesn’t makes sense to me, way overpriced.

Expensive, yes! But to be fair, coilovers by themselves will run you $2k so that alone is more than half the cost. And typically the components between different heights (2” vs 4” vs 6” etc) are fairly similar just slightly different lengths on some components. So it makes sense that cost is similar to other kits they offer.

BDS also makes great kits with an awesome warranty! I know that doesn’t help swallow the cost of the kit haha but at least you know you’re getting quality components. But yeah cost isn’t proportional to lift height

Here is another quality option, better shocks, covers the front - then you have to add a rear set up like BDS - price shown is with 2.5" adjustable kings

The 4” lift and the coil over lift have the same components, except the non coil over lift comes with 4” spacers for the top of the stock struts. So the pricing is 100% in line. I had this kit installed a week ago with the dual speed compression adjusters and couldn’t be happier. I ran 2.5” kings on my 4Runner and they leaked all the time. I rebuilt them 4 times and when I got rid of it, one was leaking again.

also, kings should really only be lifted 2.5” , which puts you .5” over stock height on a trail boss / at4. Once you add rears to that king kit, you’re at about 4k as well. Mind you, those rear shocks from king are much nicer than the standard fox shocks on the rear of the bds kit. If/when fox releases some better rear shocks, I’ll most likely upgrade mine.

is your truck and AT4 or Trail Boss- if so how does the ride compare? AT4 street ride is really good - want better shocks, but not at the expense of the ride quality

At4. I hated the stock ride. Way too mushy. I’d hit a speed bump or back out of a drive way and bounce all over the place. The new coilovers just soak it all up. Obviously going from a p-metric 31.5” street tire to a 35” f rated lt tire, you feel more bumps in the road, but the trade off is worth it to me.

I did the icons too, mines set at 3 inch but I used rc forged control arms since I didnt think I needed 900.00 control arms to drive to work..lol.. It handles really good but is firm. I'm afraid to turn it to 3.5, with adding preload would it get too harsh I'm not sure. To me this is prob the best bang for the buck. I do have kings on my 2500hd for years and they are flawless..

Did you go with the Stage 1 or Stage 2. And if Stage 2, did you go with tubular or billet aluminum upper control arms. Debating on going with Icon, but not sure if I need the upper control arms or not...I have a Trail Boss.

Thanks

FirstAscent · January 27, 2020

Do you NEED them, no. Do you WANT them. yes

Their control arms typically offer more travel when combined with their coilovers and also provide better angles after being lifted. However, some lifts are designed around the factory UCA so they aren't required.

I've had their billet UCA's on two different trucks now. Did I notice a difference? No, not really. I had good alignments with the factory arms but damn do the billet UCA's look good! The billet arms also offer a LOT more adjustability and fine tuning.

I should add that my experience only comes from using the truck as a daily driver and not off road where I imagine UCA's play more of a role.

Would I buy them again, YES. without a doubt.

Jaimie, thanks for your response. I guess ultimately what I'm wondering is whether I "need" them if I'm simply leveling out the front with the rear. I believe if I remember my measurements correctly, my front is about 1.5" higher than the rear on my Trail Boss.

I understand with some of these "leveling/lift" kits, that folks are also adding taller rear blocks and cranking their coilovers to the maximum 2.5-3 inches. In that case, I could see needing new upper control arms among other things I'm sure, which is why the BDS kit has so many components.

If I'm simply leveling out the front 1.5 inches, are they required (will my truck align just fine)?

Even if just leveling your TB upper arms are recommended. If you just want to level the Ready Lift SST kit is the best bang for the buck - $510 plus tax, free shipping from Tire Rack for the AT4/TB. If you want to add upgraded shocks down the road you could, but it would not be as "complete" a designed system as BDS is offering - so you just have to decide how many $ you want to spend the pick your best option.

Watch this video from Ready Lift as to why you need to add upper control arms - you are correcting geometry the stock upper arm can't handle.

Did the Ready Lift 2" SST level kit on my 2019 AT4 Carbon Pro - lost use of "auto 4WD" as RL does not recommend use. I just traded it for a 2020 AT4 Carbon Pro to get trailer tow mirros and new trailer tow camera tech - as I tow fairly often.

Going with BDS 2.5" kit with Fox 2.5 DSC coilovers - figured might as well do it right this time!

Looking forward to the upgrade - hope to have it install in a few weeks!
