So yeah....I finally got those big brakes put on OVERCLOCK3D! I've been procrastinating, because I knew it was going to be a tight fit. I ended up taking my Jeep down to World Tour Offroad in Annapolis, MD, and changed the brakes there in front of the shop. Then I could test the fitment and work with Paul to relocate the wheel weights and get all of the tires rebalanced. It was a pain in the butt.... but all good now! The ProGrips really do improve braking... especially in my heavy JK!
The Dynatrac ProGrip™ Brake System comes with larger rotors for the front and rear, providing improved braking by moving the factory calipers farther from the axle centerline. The increased rear braking power provides balanced braking, reducing nose dive and dramatically improving the control of the vehicle in mild and hard braking conditions compared to upgrades that only address the front brakes. Significant research was done to select the optimum front and rear brake-pad linings to balance the system and provide additional stopping power.
Fully instrumented testing showed lower brake pedal pressure and a reduction in stopping distances of up to 30 percent compared to stock brakes on a Jeep JK outfitted with a 4-inch lift and 37-inch-tall tires. Measured G-force during moderate braking (1,000-psi brake fluid pressure) increased from 0.48 Gs with stock brakes to 0.63 Gs with the Dynatrac ProGrip system.
Another key advantage is that installation of the system does not require opening the brake hydraulics, thus avoiding the chore of bleeding the brakes after installation. Additionally, brake pedal feel and travel is improved after upgrading to the Dynatrac ProGrip Brake System.
The system is a direct bolt-on for 2007-2017 Jeep Wranglers and it includes:
13.50-inch front rotors with unique pillar-vented cooling design
14.25-inch rear rotors with integral parking brake surface
Stronger caliper brackets designed using CAD/FEA and advanced engineering tools
Unique front and rear brake pads for optimum friction performance
The Dynatrac ProGrip Brake System fits Jeep Wranglers with 17-inch wheels (wheel spacers are required with 17-inch factory wheels), and the system will fit in nearly all aftermarket wheels without spacers.

Nice video. Thinking of doing a big brake kit also on my JK. Appreciate these videos always learning something new. Pretty cool. Love those military style beadlocks those are beast and very good looking wheels. Cheers!
ReplyDeleteI really REALLY like these Rock Monsters! The big break kit from Dynatrac is nice (ProGrip is the actual name). It's a tight fit for sure tho, depending on what rims you have. I started out with them on the rears and realized quickly that it was stripping my weights off!!! So I held off adding them to the fronts until I could get all the tires re-balanced so the weights could be placed on the wheel where they wouldn't hit. It turns out there really wasn't any clearance issues in the front... just the rears. But you have to account for tire rotations, so every tire had to be re-done. Worth it in the end. The Jeep stops much better now!!!
ReplyDeleteWhat's your backspacing on those wheels? I was under the impression that if you went 4.5 or more you were safe to throw big break kits on.
ReplyDeleteIt's not about backspacing as much as it's about the inner wheel diameter. This may help.. https://www.dynatrac.com/downloads/Wheel-Fitment-Instructions.pdf Backspacing on these is 4.63".
ReplyDeleteGlad you guys figured this out!! I've got DynaTracs too and I was over at Paul's last month and he said balancing would present a challenge. I'm going back this week or next for a driveshaft install, wheel bearings, tire balancing and diff service. We're also trying to figure out why the steering feels loose and flighty, we're thinking it might be the Yeti attenuator.
ReplyDeleteNavy term PFM...
ReplyDeleteHal 9000 LOL
ReplyDeleteInteresting about the steering. loose and flighty definitely doesn't describe my experience with the Yeti attenuator. How's your caster?
ReplyDeletePaul checked everything including the alignment and he seemed to think it was fine. He was suspicious of the ball joints, but they are DynaTrac prosteers with less than 10k on them. The steering was tight until I went with the yeti parts, drag link flip bracket and the prosteers I added the pro grip brakes at that point too. Considering I had close to 70K running 35s on the stock ball joints which were flopping around everywhere and didn't have this loose feeling steering I'm having a hard time accepting it's the DynaTrac ball joints ball joints. He was also suspicious of the Yeti attenuator and said he wanted to talk to you about it, don't know if he did though. I've got a Fox ATS steering stabilizer and have read that the Yeti likes the stock ones better. Other than that I'm kinda out of ideas and hoping the new wheel bearings and rebalancing may tighten things up.
ReplyDeleteOVERCLOCK3D Jeeps Absolutely worth it. Do something do it right the first time and have that piece of mind. If I can't do it right, I sure as hell am not going to do it half ass. I do things as my time, capability, and finances dictate. God bless you. Appreciate you replying back. ✋😀
ReplyDeleteShould try 6mm air soft bullets in tire would need weights
ReplyDeleteartstump3 balancing beads were the last resort if this weight strategy didn't work.
ReplyDeleteIve got the Teraflex big brake kit going on this week - front and rear. Hopeful I dont need to move the tire weights.
ReplyDeleteI hope not... I haven't heard of people having issues with them. Just spin the tire after you get it mounted back up. If it's gonna hit, it will do it immediately, and you'll hear it.
ReplyDeleteOMG! OMG! You didn't do it yerself!!! You must not be a real Jeeper! (at least that is what I've been told)
ReplyDeleteTalez From the DashCam ha! Last I checked I don't have a $40K tire balancing machine in my garage. Hahaha
ReplyDeleteI don't have the tools or the time. Why spend hours beating my head with a wrench, when a professional can do it right quick. Then I get $h!t on by Trolls....
ReplyDeleteCan't avoid the trolls!!! They are everywhere! lol
