Born from racing, BoXXer promises one thing above all—composure. By eliminating chaos before it reaches the rider, every run delivers predictable speed, traction, and control. The all-new LinearXL air spring provides a coil-like ride—supple off the top, supportive through the mid-stroke, and backed by a jounce bottom-out bumper for confident end-stroke control—giving you unwavering consistency and predictability. Found only in our Ultimate forks, ButterWagonTech ensures a constant supply of oil to the bushings, reducing friction and maintaining smooth performance throughout the entire service interval. Intuitive HSC/LSC controls on the Charger 3.2 damper with ButterCups technology make setup fast, understandable, and easy to communicate. You’re so composed you don’t realize you’re going faster. But the clock says it all.

  • NEW LinearXL air spring delivers a consistent and predictable ride feel backed by a jounce bottom-out bumper for end-stroke control

Works as intended
Size: 1-Female to 2-Male Y-Adapter-1 ft
What can I say? Works as intended. Seems pretty decent in quality and has a decent thickness to it! Fits pretty tightly so you don't have to worry about sloppy RCA connections.

Great Quality
Size: 2 Channel-3 ft, Size: 2 Channel-3 ft
Outstanding quality a very reasonable price. I was able to check the headunit RCA was showing almost 5 volts which was rated on the output of the headunit. I’m not an expert however i am assuming you don’t have to add so much gain. I’m very pleased and i will save this seller.

Pretty good cables for what they are
Size: 2 Channel-3 ft
I purchased these Skar Audio cables here on Amazon because they were an outstanding price. They shipped very quickly. When I open the package mind you they do work pretty good but when I open the package I've noticed that the gold plated connecting points that are supposed to connect to your amplifier and your receiver are a little flimsy and don't fit as tight as they're supposed to so I was concerned that bumps on the road whatever would cause them to loosen up so I had to squeeze them together a little bit so I can make them fit tighter on the amplifier but so far so good and I've had no problems with them. I've had no weird humming no weird crackling or any kind of connection issues whatsoever since I've done this. Just something to take note. Other than that, for the price these are pretty good cables and if you want to spend a little more here on Amazon you can get better cables. I know Skar Audio makes pretty good speakers for what they're worth and they definitely make pretty decent amps. I'm just not quite sure about there quality on cables and such. Just my honest opinion. I know people that love everything that they make so it's all subjective and a matter of opinion. Would I recommend them? For the price definitely.

Another Quality Product from Skar Audio
Size: 1-Female to 2-Male Y-Adapter-1 ft
High Quality RCA. I needed a 1 Male to 2 Female RCA Y adapter, and me not reading correctly ordered this. However - I managed to make this work at my AMP instead of the head unit. Great sound quality, Cable is a good gauge and matches my RCA's already ran in the car. Connects easy and had this installed within minutes. Thanks Skar!
