The 3.5? suspension is one of our most popular and versatile systems. With its Alpine IR Long Arms & Brackets, the new Alpine RT3 Long Arm provides a completely new driving experience. This kit provides maximum adjustability. TeraFlex Alpine RT (Rogue Trail) Suspension Systems build on our already capable Alpine CT (Cross-Trail) Suspension Systems. These systems include all our top-of-the-line components. The 3.5? suspension is one of our most popular and versatile systems. With its Alpine IR Long Arms & Brackets, the new Alpine RT3 Long Arm Suspension System provides a completely new driving experience. This kit includes HD Forged Adjustable Track Bars and Track Bar Brackets for maximum adjustability making them the perfect mix of performance and comfort. Adjustable Alpine IR Long Arms balance front caster angle and pinion angles as well as optimize rear pinion angles, anti-squat geometry, and tire position on vehicles with 3?6? lifts. On higher lifts, Long Arm Brackets reposition frame-end control arm mounting points to restore near factory orientation to reduce bushing stress during extreme droop as well as shock load transferred through the Long Control Arms. Alpine IR Control Arms feature our Independent Rotation (IR) Bushings. These innovative bushings remove bushing bind during full suspension travel for less overall bushing load during articulation resulting in unrestricted droop as well as a noticeable ride improvement whether on the highway or the trail. HD Forged Adjustable Track Bars and Track Bar Bracket(s) improve steering response, center the axles to optimize vehicle roll center, and reduce body roll for unsurpassed handling. This results in improved suspension geometry and relaxed control arm angles for a superior ride quality and performance regardless of terrain. These systems restore front and rear roll axis angles to minimize brake dive and acceleration squat. TeraFlex suspension systems provide reduced noise, vibration, and harshness (NVH). Alpine RT Suspension Systems are for the Jeeper who wants it all! Does NOT include shocks. We recommend Falcon Performance Shocks. Sold separately.

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
Size: 20 sqft, Size: 20 sqft
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

Good stuff
Size: 50 sqft, Size: 50 sqft
Good stuff. I did a lot of work on my 91 Toyota Land Cruiser 3FE. I did the inside and outside doors, as well as the under-hood area, with some extra work. I like this stuff. It sticks down good but you have to clean your surface so there's a good grip. I think these are going to do well for noise cancellation. The deadening material does well with absorbing vibrations too. But the install roller tools it will come in handy. Trust me trying to do it by hand is not worth it.
