The 4.5? Alpine RT4 Long Arm Suspension System excels on the highway, off-road, through the desert, or rock crawling! Alpine IR Long Arms & Brackets and HD Forged Adjustable Track Bars allow full 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 4.5? Alpine RT4 Long Arm Suspension System excels on the highway, off-road, through the desert, or rock crawling! Bolt-on Alpine IR Long Arms & Brackets, HD Forged Adjustable Track Bars, and Track Bar Brackets allow full suspension adjustability, while the SpeedBumps smooth out unexpected trail bumps. This is the ultimate suspension with a lifetime warranty. 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.

Good enough
Color: Black
Comfortable chair. Easy to put together. Allen nuts aren't cut perfectly so sometimes hard to get the wrench in there. My biggest complaint, and I didn't even realize this until I sat down in it, the arm rests are not adjustable and they are a little short for my liking.

I love it!
Color: Black
This chair is so comfy! I also love that it goes up super high (as a tall man it's nice to have the kicking my feet sensation... Lol). It's wider than I imagined and it the first chair with arms that I can fit in as an almost 500 pound dude. The lumbar support is nice and also adjustable, too. The wheels are high quality and move you fast. It was pretty easy to put together, but deff get help from someone to hold pieces in place

Very sturdy and well worth the price!
Color: Black
First, my chair arrived faster than I expected! It was delivered in a well packed box and everything was plainly marked! It assembled very easily as per the instructions. The only thing I would recommend is to have another person available to assist with the installation of the back rest onto the chair. It gets kind of cumbersome for one person, although I did it myself… another tip start all screws before tightening, especially with the arms and the back rest cushion! It only took me about 25–30 minutes to do the whole thing by myself.. The materials are of good quality, very sturdy and I really like the dual casters as they glide on the floor really nice! Well, worth the price!!! Mike P

My best office chair!
Color: Black
I haven't really given a lot of reviews before. But that said I weighed 260 at 6 ft 3 in. I have to admit this is a pretty comfortable chair! It was easy to put together, and my legs don't go to sleep anymore sitting in an office chair The lumbar support is really good. I'm just glad I was able to find this chair, and about my son another one and it'll be here Friday! You can't go wrong with this chair! I love it so far!
