Upgrade your Jeep Wrangler JL and Gladiator JT with RockJock’s Johnny Joint Front Lower Control Arm Set – a durable replacement for your factory control arms. Adjustable arms are vital for aligning lifted vehicles and ensuring your caster specifications are in check.
These arms boast RockJock’s 2 1/2-inch Johnny Joints, the original and most robust high-articulation urethane suspension joint in the market. With a smooth steel ball pivoting inside a specialized urethane shell, these joints provide over 30 degrees of quiet, shock-dampening articulation, without the excessive deflection seen in soft rubber-based flex joints. Whether you're cruising on-road or tackling off-road challenges, Johnny Joints offer a smooth, comfortable on-road ride coupled with unmatched off-road capability. Their reliability is evident, as multiple commercial suspension companies rely on them for both street and off-road systems.
Additionally, these arms are fully greasable and come with mounting studs in the stock location for easy re-attachment of brake line brackets. Finished with a semi-gloss black powder coat on the arms and gold zinc plating on the Johnny Joint adjuster ends, this control arm set ensures durability, performance, and a sleek look for your vehicle.

A Must Have For Sound Deadening Materials
Size: 3 Pack
I applied Silex sound deadening material to the rear interior of a Ford Maverick truck cab. Lots of narrow areas, and lots of curved surfaces. This set was a must to properly apply the mats to the metal surface. There were places that I had to push down with my fingers due to obstacles like seat belt mounts, but I could tell that I was not getting the same results as I was with the crimped rollers.

Would recommend
Size: 10 sqft
I used this sound deadening material in my car during an audio and interior upgrade, and the difference was noticeable immediately. Road noise, vibrations, and rattling were reduced a lot, especially on the doors and floor panels. The car feels much quieter and more solid while driving now.
The material was easy to cut and apply, and the adhesive stuck very well without peeling up. It has a quality feel to it and conforms nicely around curves and tight areas. I also noticed my speakers sound cleaner and have better bass response after installing it.
For the price, this sound deadening material is a great value and definitely worth it if you want a quieter ride and better overall sound quality in your vehicle.

Worth it!
Size: 50 sqft
I was worried it wouldn't work as well since it's 50 mil and I thought I got the wrong thing. Nope! Works great. Did all four doors on my 93 civic and I have enough for the floor I think. Solid price. Noise reduced by about 5 decibels hive difference. Very sticky and easy to apply I'm so happy I was able to cover most all of my car. If I need more, definitely buying this since I got so much extra and I thought I would.
PS: that five decibel thing is only with the four doors. My firewall is next and then my floor, but it's such a huge difference

Quiet your vehicle noises
Size: 50 sqft
Put this in our high roof van and couldn’t believe how much quieter it was at once. Really cut down on the vibration noise Nice and easy to install just peel n stick. Was also easy to cut with scissors for smaller areas. Seemed to be really nice quality. Didn’t notice any odor.

Sound deadening the Hot Rod

Works well, good value for the money.
It’s very sticky and conforms to what you are applying it to. One 20 sq ft box did approximately the passenger side
