DPG OffRoad's new TrailGunner springs

DPG OffRoad has finally released their new TrailGunner line of leafs and coils for XJ's and TJ's. Dirk has been working on these springs for nearly 5 years now, tweaking the design until they work exactly like he's wanted them to and making sure they'll stand up to long term use and abuse. He's been talking to me about his leafs for about a year now I guess, and as soon as he told me they were ready I jumped on a set, and got a set of his new matching coils too. I needed new leaf springs anyway (years of axle wrap have taken their toll), so the timing was perfect.

Right now the XJ springs are available in one height: 5". The reason is this seems to be about the magic height for XJ's. Low enough to maintain good stability and a low CoG, but tall enough to run up to 35's with the proper trimming. For lower lift heights I think Dirk generally recommends OME springs, but he's really aiming at the 33-35" market with these new springs.

Dirk designed his leafs to be used with the stock shackles to keep things simple and stable, but you can use lift shackles if you want or need more lift, or if you've got a fairly heavy rig. I fall in the later category so I'm going to be running his springs with a set of JKS 1" shackles (down from the 1.5" RE boomerangs I'm running now). I've got a set of 3/4" poly coil spacers for the front if I need them to level things out.

To help with axle wrap, sagging, and overall durability Dirk designed his leafs to be a 7-leaf pack, vs 6 leaves like most other springs on the market. They've got rubber bushings of course, and there's an extra spring clamp up near the rear spring eye that Dirk says helps combat spring wrap. I'm not entirely sure how that works, but he's the one that's done the R&D and testing, so I'll take his word on that. ;)

The springs are going to be on the firmer side of things for better road handling and greater stability in offcamber stuff offroad, but Dirk has assured me the springs won't ride "rough" on the road. He also recommends running a quality pressurized shock with them, like OME, RE's Monotubes, or even Bilsteins if you like a tighter feel. I've already got Bilstein 5150's up front, and will probably be going with some OME LT's in the back once I raise my rear shock mounts.

I got the springs last friday, but due to other projects (and the SuperBowl) I didn't get a chance to install them over the weekend. I'm hoping to get them put in this coming weekend though, so I'll have more to report back once I get them installed and see how much lift they net on my heavy XJ (it's not fat, just big boned) and how they ride on the road. We don't have another wheeling trip until the first or second week of March, so I'll probably be a while before I can report on how these springs perform offroad. From what I've seen of these springs in action on Dirk's XJs though, I think they'll do great.

Here's a pic of the leafs and coils:

Here's DPG's 5" leaf (top) vs RE's 3.5" leaf (bottom; I didn't have a 4.5" leaf handy):

It's kinda hard to tell, but the DPG spring does have more arch to it than the RE spring.

The leafs sell for $416/pair plus shipping, and the coils (XJ or TJ) are $175/pair plus shipping. They're available through DPG OffRoad and JeepinOutfitters.com, and they're available by themselves or as part of some trick new JKS/RE/DPG hybrid lifts that Dirk is putting together.

Here's a press release I got from Dirk about the springs:

==============
5 years of R&D at DPG OFF-ROAD has produced a set of springs that are the highest quality available anywhere. We wanted to build springs that were firm enough to provide exceptional handling and off-camber stabilty, while also allowing for excellent articulation and a very good ride. That's not something we've seen in most aftermarket springs available so far. We felt like we could do better than what was available and we set out to design a spring that would accomplish just that.

Our coils are all manufactured to the highest standards on precision mandrels to insure that they consistently meet our rigid design specs. Every coil is load tested and shotpeened to reduce stress and lengthen spring life. Ramp angles are lower, which also allows for longer life and more fluid operation and articulation. DPG TrailGunner coils duplicate the original manufacturers end configuration for a perfect fit on your jeep. Simply the highest quality coils available for your TJ or XJ!

Our DPG TRAILGUNNER LEAF SPRINGS are truly different. A proprietary mix of complimentary leaf spring alloys are combined in our new 7-Leaf XJ packs. At appx 5" of lift, they are a sorely needed addition to the aftermarket leaf spring line-up for your XJ.

Our 7-leaf design and exclusive anti-wrap features greatly reduce axle/pinion wrap under torque. Off-camber stabilty as well as on road handling with these packs is excellent. No more "wallowing" or "porpoising" around corners or when hitting bigger bumps. They provide a firm, sporty feel but still provide a very good ride as well. The added control afforded by these leafs will benefit heavier jeeps too, which tend to have stability issues with less substantial springs. A true innovation in leaf springs for your XJ!
========================

Holy crap this turned out to be a long post! :gag:
 
Jason, can you tell us how much actual lift they give when you install them. I have an ARB bumper and winch, so there's a lot of weight up front. I'm looking to replace my RE 3.5" coils and 1.75" Daystar spacer and get about another inch of lift. I was thinking about the Skyjacker 6" coils.
 
Absolutely! Dirk's XJ is fairly lightweight compared to mine, and since I've always seemed to have an issue with leaf springs on my rig it'll be a good test to see how they hold up under my rig. The coils too. I don't know the weight of my C4x4 front bumper, but I know the rear bumper/tire carrier is about 132#, plus about 90# for my spare tire. I figure my roof rack adds another 50# or so, maybe more. Then of course a winch (synth rope/fairlead), rocker guards, belly skid, and gas tank skid...

I'll have before/after measurements for my rig, but I need to find a stock XJ to get some measurements off of again. The measurements I'll post should allow folks to compare against their own rig, to see where they'd be with the DPG springs relative to where they are currently.
 
Jason,
Is Dirk on here himself, or would I have to go to his site (or jeepin) to ask him a question about a custom application?
 
I'm sure Dirk's on here, don't know how active he is though. I'd probably just shoot him an email about whatever it is you're wanting to know. I know he's posted in my thread on my forum, so you might post there too.
 
Do you have spring rates on the coils and leaves? The leaves look really nice. My 1462's leave something to be desired...I think it may be coils or coilovers though:D

Anyway. Do you have the numbers? Thanks.
 
These sound like very nice springs. As soon as my tax return gets here I am going to replace my tired RE's, and I will be ordering both front and rears from ya.

Brad
 
Can you measure these eye-to-eye? Aftermarket spring makers need to make them a little longer overall to compensate for shackles to keep proper angle back there.
 
Nice looking kit. I was going to do a BB ontop of my RK 4.5" but now I just may use my tax return for a set of these...since I already have the adjustible control arms and trac-bar, should be an easy swap!
 
cool, been needing a set of new springs and was going to go with Big Offroads's or custom but may take a serious look at these. One thing I wonder about is how they are handling reverse arching?

Also the height is a little high, I like the 4" springs with a 1" shackle lift but....
 
BOR won't give out spring rates, most places I have asked declined to give out that information.

True, but I guess to me it doesn't matter if ABC is making them, I'm more interested in the process and treatments they use. For example I would never buy spring from Alcan but BOR has their springs shot peened so I would buy BOR.
