    BTW, I don't recall if I already posted this, but we went out wheeling last week and my gosh did this kit make a difference.

    The biggest area I noticed was the softness and ability to handle rough terrains at higher speeds.

    I'm starting to plan my next tweaks on my BP51 setup. Today, I'm at 20/23 preload on the front. I've got a second battery (55lbs), ARB Twin (20lbs), Xeon 10-S (80LBS), Warn Semi-hidden bumper (80 lbs) and sliders (~150 combined) on this truck. In the rear, I've got my RTT (160lbs) and canopy (150lbs) and fridge, plus gear.

    I feel like the front end is really stiff, but haven't adjusted the compression rebound yet. I also noticed that after my alignment, my height gain seems quite low, I am seeing the ~24" hub-to-fender in the rear, up front I am barely at 22". The 3mm difference driver to passenger seems to keep it level, though, as I am within 1/4" on both sides.

    I'm toying with taking a little bit of the preload out to soften the ride, but worry that'll further reduce the right height on the front end. I'm seeing a lot of posts indicating most folks with similar set up are closer to 18mm, but I am curious how much of a difference 2mm will really make in this scenario?

    I'm also thinking my immediate step is going to reduce the compression and rebound by a click or two on the front and see if that softens it up a bit.

    Anyone else been in this spot and care to share insights? Appreciate all that this thread, and the other BP51 threads, have provided for me!

    I wasn't happy until the preload was 10mm on passenger and 12 on driver. Otherwise the ride was poor and it topped out like crazy over small speedbumps.

    With comparable weight on the front?

    What is everyone's thoughts on air bags to adjust in temporary extremes in hauling coupled with this bp-51 complete kit. I'm talking maybe loading with 600lbs in the bed and towing a trailer with 400lb tongue weight occasionally in summer months.

    Does the BP-51 complete kit setup, paired with aftermarket UCA give you any extended length of travel over stock suspension or is that part of it the same?

    Just got the truck back from the installer and driving for the first time over moderate bumps was amazing. So then I took a large bump at a bit faster rate and bottomed out the rear suspension, hitting one of the rear boxes. My question is in the rear are the shocks adjustable for height? I see that I can adjust them for a stiffer rebound. I'm afraid that the installer who also put on the flatbed may not have provided enough clearance for the rear suspension travel.

    Need to run the truck over a scale

    The picture below probably has the truck parked on a backward slope

    Thanks for your thoughts

    I believe the only way to raise it at this point would be to run additional leaf springs.

    I don't want to body shame, but she looks heavy.

    Yup, you're just being honest. She was designed and built that way. BP-51's with Dobinson heavy duty springs, ARB front and rear locking diffs, load range e tires. She's built to drive around the world starting next year. If interested in the build and the TW discussion, my thread is "Taking a Tacoma around the world,need advice"

    Looks heavy for sure. What's your current spring pack config ?

    Ah good question. What I do know is that installer who’s a very well known overland company in the Seattle area put on Dobinson heavy duty rear springs. These Dobinson heavy rear springs are rated for loaded Hilux trucks running up to 2000 lbs of payload. Is there a way to look at them for the specific config?

    I do know that there’s 9 leaf springs. I’ll send a photo tomorrow

    It's a way heavy rig, no doubt about it.

    Is that just the way your tray fits? Is it rubbing? It's tough to tell from that photo, but I'd start by seeing if the truck sits close to level. Park somewhere you know is level and see how it looks?

    How would this kit handle on a stock weight truck? I plan on slowly upgrading to bumpers etc down the road. Right now the truck is a daily so it is seeing 95 percent highway. Would it be too stiff, or is there enough adjustability to tweak as I go. I've been weighing my options and this is on the short list. Thanks in advance.

    That is the way the tray was mounted using the standard Norweld mounting system for the Tacoma. It does not rub but only has about 4 inches of total travel in the rear suspension, clearly not enough. The installer used the heaviest duty Dobinson rear springs and they are almost flat so we’re reviewing our options. May have to go with a custom Deaver or Alcan setup. Good idea on taking it to a level parking lot with my 4 foot construction level

    Coming from the extreme other end with a very heavy Tacoma, I’d say the BP-51 shocks can handle all ranges of weight. The problem will be as you add more weight, your springs will need to be changed out. Just my thoughts. BTW, I’m very impressed with the ride quality of the BP-51s. Absorbs moderate washboards with almost no impact felt in the cab yet it does not sway much when cornering. Never have ridden in a rig that does this

    I’m planning to get this kit on my truck. My truck is stock minus a bakflip mx4 Tonneu Cover and Maybe 50lb of gear in the bed. so maybe 80lb max in the rear area. I may install sliders down the road but basically gonna keep the truck stock plus Sliders.

    What would others recommend for my preload up front on the stock Truck?

    I’m thinking maybe 7mm driver 2mm passenger. My goal is to sit level. If at all possible. I’m planning to remove the 3rd leaf from the top to turn the HD pack into the “medium duty” pack. Would you recommend also removing an overload spring on top of the 3rd leaf from the top? I’ve seen this referenced to remove an additional .5” of loft in the rear. Which overload spring do you remove the very bottom leaf or the second one up?

    I’ll also be running airbags with daystar cradles for the rear for when I will load down my bed with dirt bikes and tow. This will help compensate for 800~1200lb of added combined tongue weight and bed cargo. This will only be a few times a year if that so I don’t like the idea of beefing up my pack and having a large rake to the truck for everyday daily driving just for those few times. Normally the bags will be flat to 5psi not adding anything to the springs.


    My goal is for 2-2.5” of lift all around. Lots of good info in this thread. I hope I can get close my first time around!

    Just looked at this tool on Amazon and There’s a guy that posted a review on how he uses this tool to adjust preload while the shock is on the vehicle. It’s a 4runner not a Tacoma but shouldn’t matter right? What do you guys think? Safely doable?

    I’m trying to figure this out as well so I can use his measurements accurately.
