What It Fits:

The Special Sauce:
Housing
- SAE 1045 Solid Steel Forged Housing: This is unequivocally the best carbon alloy steel for this application.
- Knurled Housings: The preferred design for aftermarket installations.
- CNC Machined Housing: Make our parts and bearings dimensionally perfect, eliminating any die wear issues.
Ball Studs
- SAE 4140 Hot Forged Chromoly Ball Studs: For the strongest possible metallurgy.
- Induction Heat Treated Ball Studs: Provides a very precise heat treatment to the exact depth and location we want it.
- Polished Ball Studs: Built like an anti-friction bearing with extremely precise tolerances.
- Rolled Threads: Made by pressing the shape of the threads into the ball stud instead of cutting. This strengthens the threads instead of weakening them and allows for easy movement of hardware. This ain't no Ikea furniture!
- Step Threads: Allows for very easy movement of hardware on install and superior holding when torqued (installer choice).
Bearing Design
- Bronze Bearing Design: Our newest improvement in bearing design. Combines our perfectly polished ball studs, encased in a solid steel forged housing, lined with a highly durable, low friction bronze bearing.
Boots
- CR Rubber Boots: The most durable material for undercar applications. Resistant to deterioration from road level ozone, oil/gas/engine fluids and extreme heat or cold.
- Internal Seal Boot: The boot is coined onto the ball joint, for superior sealing against contaminants.
Finish
- E-Coating: Extremely durable electrochemical finishing process
Hardware
- Grade 8 - Class 10.9 Hardware: Superior tensile strength.
- Castle Nut: Industry standard where high vibration loads occur.
Lubrication
- Pre Threaded Zerk Housing: If you have ever installed a MOOG Ball Joint without a pre-threaded zerk fitting you will understand what a simple but great feature this is. Another installer fav.
- Greaseable: Because it should be.
- Pre-Greased: Just in case you forget, we have you covered.
- Gull Winged Grease Grooves: Allows for improved lubrication disbursement around the ball stud.
- Zerk Fittings: Included for every application.
Special Features
- Custom Features: Lower: Angled Zerk housing for easier servicing.

Quality mats that provide noticeable noise suppression
Size: 10 sqft
I used these mats when I replaced the carpet in my Chevy Tahoe. Cutting the mats to size was easy enough with a utility knife and a straightedge. The adhesive backing stuck fairly well, but I used a roller to press the mats into place on the metal panels, which seemed to help them adhere a little better. Under the old carpet was the type of insulation you'd typically see under carpet in a typical home. It was worn, so I tossed it and installed the new carpet directly over these new mats. The before & after difference in noise was minimal, but noticable. But I only installed them on the floor - not in the doors, rear hatch area, firewall, or roof. So overalll, I'm pleased with these mats as they provided the noise suppression that I had expected.

Easy to cut and easy to install
Size: 10 sqft, Size: 10 sqft
You receive 9 sheets of RUNSUNSPRII Car Sound Deadening Mat that each measure 9.75" x 15.75". This calculates to a total of 9.6 square feet in total for all of the sheets. Of all the different styles of sound deadening mats, foil lined butyl is the best type for eliminating vibration. This quality product has a printed gridwork of 2-inch squares on the liner to aid in cutting the correct sized pieces.
Even with as sticky as this product is, it is super easy to cut to shape with one pass of a razor blade. OEM auto manufacturers use this same kind of product extensively on the inner structure for sound deadening and to block sound and air transmission through all sizes of holes and cutouts. Because it is highly waterproof, it also is perfect for blocking areas to prevent water intrusion. The very sticky pads adhere to all surfaces and are very flexible and will conform to fit many areas. Because it is thin, it is ideal to install under interior trim panels without causing interference with how the panels fit.

Solid quality and good price
Size: 10 sqft
I bought this for my custom built camper van and it’s been great so far. For $24, the amount of coverage you get is totally fair, and I’ll probably grab a second box to finish everything. It’s easy to install with just scissors and something to press it down, and making quick cardboard templates really helps for tight spots. The adhesive is insanely strong, so once it sticks, it’s not going anywhere (just don’t let it stick to itself). Keep in mind this is sound deadening, not full soundproofing, but even with partial coverage I can already hear a difference in reduced road noise and vibrations. I’m using this as a base layer and plan to add soundproofing on top, and so far I’m really happy with how it’s turning out.

It's a job but totally worth it
Size: 36 sqft
Pack a lunch when you tackle this project boys.. its a doozy!! Month in going great so far definetly did what I purchased it to do. 2000 chevy with two p3 10s every bass drop sounded like an old firebird with loose trunk bolts. Threw this on the back walls floor underneath the speaker and the doors.. all that energy is now in the cab with me instead of getting lost in rattling metal!! Love it!!! Left a few pieces outside after I was done rained like hell on them so water doesnt hurt this stuff at all or direct sunlight in south mississippi.. good stuff pick this up and make them systems thud instead of rattle!!! You wont regret it!! I didn't!!
