Any idea what leaf spring this is?

Hey guys!, bare with me here I am new to Tacomas and trucks in general.

Background:

So it's been 10 days with my truck that I got used, and overall I love the performance and ride quality in the desert which is mainly what I got it for. I havent started upgrading or modifying yet, but I plan to work on the rear end first. Ultimate plan is to either go with a SUA bed cage or 4 link(most likely linking it in the future).

The front end is very smooth and rides extremely well, floats over mostly everything here in the desert, however the rear end is a different story, rear end feels very stiff and bucks easily. Granted the rear end does not have any major modifications to it (travel). Front end has the +2 LT Kit(11 Inches of wheel travel) with a single KING 2.5 Coilover and rubber bump stops.

Rear end has a 2.5 KING Shock (Standard Stock Wheel travel) with 2.0 x 2.0 KING Bump Stops @100 PSI.

* Rear end is unloaded, no weight. I never haul or tow with this truck, mainly open desert fun.

I am not sure which leaf springs are on my truck though, I don't think they are stock OEM leafs since without load it is sitting way to high in the rear, 2.5+ inches in the rear over stock height. Rake. They are to stiff also, to much spring rate.

I am guessing the leafs are heavy duty and are to stiff for unloaded situations, maybe previous owner used to haul stuff.

Questions:

1. Any idea which leaf pack this is (does it look like its a HD leaf)?

2. If you focus on the video, you can see that the rear tires only go half way up before stopping, plenty of room for uptravel there, maybe the bump stops are designed to stop it there because of the stock leaf geometry or something ? Since I heard that SUA kits will allow more uptravel, Will it be okay if I lift the bump stops up a little?.

* I also noticed that the 2.5 KING Shock still had about 2 inches of uptravel left at full bump.

Thanks a Bunch guys, help is very much appreciated

 

It's a Dakar HD pack.

 

That was quick!, thanks!. Just searched it "OME says these springs are for vehicles carrying an extra 660+ lbs at all times". Way to stiff for a completely unloaded truck thats what has been causing the stiffness and buck. Considering a switch to Deaver J62's now.

 

Noted, thank you. I am doing some research now and will either relocate the shocks with 2.5 x 10-12 KING Bypasses and go with deavers for now, or a DMZ Sua kit with a bed cage.

 

I've heard most say Deaver J62's if you plan to permanently be unloaded. I have heard that ICON RXT would be very beneficial over the J62's, only if I occasionally load up.

 

I run the RXT’s with b110’s and love them. However, if you’re all about playing in the desert and have the money, go spring under with shock relocation (and you’ll have to swap shocks too). Leave bumps where they are.

Tacoma’s need more bump travel if speed is involved in the equation

 

Did you have to extend your bump stops for this set up? Going the same route! Still happy with it?

 

I’m actually using Sumo Springs 610-40’s (blues) and I cut one wafer off. I carry a dirt bike back there from time to time. They might be a little short but I haven’t flexed it out enough times to have an issue.

Only complaint is my squeaky leaf pack. One dusty road and these things make plenty of noise for quite a while.

edit: The SS’s were a prior sag solution that I carried over. I’d need help to figure out exact length bump that’s needed. Tried flexing it out right after I installed the leaves and taking rough measurements but gave up. Had already trimmed the SS’s beforehand.
