New truck with boring looks? Have no fear, ReadyLift is here with a 4" kit for the 2020-2023 Chevy Silverado and GMC Sierra 1500 with exclusive components making the kit compatible with available Adaptive Ride Control Suspension (ARC)! The 69-39400 SST Lift Kit provides a great lift solution to achieve an aggressive yet daily drivable lifted stance while still maintaining the important factory ride and handling.

This SST lift kit provides 4" of front lift and includes a 3" rear lift block. Front lift is achieved with heavy-duty laser-cut fabricated steel top mount strut extension with an offset design to correct the strut and wiper seal angles. A CNC-machined billet Aluminum pre-load spacer is also included. Combined, this configuration provides 4 inches of front lift with minor design variations to improve driveline orientation over other kits on the market. This lift kit can easily allow for up to a 295/65-20 tire as shown here with XD Series Demodog 20x9 0 offset wheels (35x11.50 max). The kit provides the right amount of lift without exceeding the CV limits working within the OEM tolerances. (GMC Sierra can only fit up to a 295/55-20 tire due to fender flare wheel well restrictions.)

This no-cut kit includes tubular steel upper control arms with optimized ball joint pivot angles and maintenance-free TCT pivot bushings. These upper control arms are an essential component of the 4" SST Lift Kit to ensure proper suspension geometry.

For the rear, included are the popular time-tested 3" tall OE-style cast iron rear lift blocks with built-in axle pad locating ears and new longer U-bolts. With the 3" rear blocks, this GM 1500 truck will have a very subtle rake that looks great with the body lines even while towing or hauling payload.

IMPORTANT NOTES:
  • This kit is NOT compatible with Trail Boss, ZR2, AT4, or AT4X.
  • This GM 1500 kit is NOT COMPATIBLE with vehicles equipped with rear composite mono-leaf springs. The mono-leaf is easily identifiable – the U-bolt is round/circular around the top of the leaf spring. This kit only works with vehicles equipped with traditional steel leaf springs – identified by ‘square’ U-bolts.
  • Use of Auto 4 Hi feature is not recommended.
  • NOT compatible with 2019 Limited OLD Body Style.
  • NOT intended for off-road use or abuse.

Nice looking, easy to read, comfortable silicone strap, hard to buckle.
Color: Black
This watch has all the features other Ironman watches have plus a 100 lap interval timer. The interval timer is possibly the reason this watch is slightly more expensive than the other IM variants with the same size and general appearance. I find this watch to be nicer looking when going out to dinner than the more common multi-colored IM watches, though most of the functions are available on the others. My previous Ironman watch had a resin strap, which was somewhate stiff when putting it on. It was comfortable enough wearing on the river, but later in the day I sometimes took it off for comfort. This watch has a soft, stretchy, more comfortable silicone strap, that, sadly, is hard to buckle and tuck-in.

Longtime Ironman Wearer -- I Hate This Watch
Color: Black
I've worn the old Ironman 100 Lap Watch for Years I would still be wearing those watches if the Indigo on them didn't consistently fail. My main requisite is large, easy to read digital display, and the ability to turn the Indiglo on 20 seconds a day once or twice to see time in dark. If I could have found a simple watch with a large display made by any other reputable manufacturer I would have bought it instead. I have truly come to dislike Timex because their Indiglo fails so consistently, on (5) different Ironman's I've owned. Doubt this one'll be any better, viewing it a disposable purchase after a year. Unsurprisingly, Timex is an American company, all marketing no quality, and yes I'm an American, looking at something Casio Seiko, Swiss or Japanese made. They get fundamentals right in terms of quality. The band on this is redesigned. Grippier. Tougher to adjust or put on, but more apt to stay on and not slide once on. I'm used to the old band, don't love or hate this new one. I will usually take my watch off while typing for a long time, not as easy to do with this, not a dealbreaker, can see the sense in making a swimming and exercise watchband a bit tougher. I hate the branding on this watch. Bright red Ironman logo on both ends of the band near the watch. Even worse is the Timex and Ironman words ATOP the glass on the watch. This means they throw shadows down onto the watch face below the glass. This effect gets even worse with the magnification underwater. Inexcusable design flaw, simply so some corporation can self-advertise its products. The combination of these two sets of branding make the watch look cheap, gaudy, and inappropriate for any remotely formal wearing. This would not have been the case if it was understated in color scheme. Without the two red marks on the band, and the absolutely moronic decision to place the branding on the watch glass, you have something understated you could get away wearing all the time. Not with the branding. There are also two lines running horizontally above and below the time. I hate these when I'm looking at it underwater. Haven't tried the lap functions yet, I usually open lake swim, maybe the lines help with that, but for my use I hate them. I'm 6'4" tall, people complain the watch is big, it feels to me if anything a bit undersized or the proper size, others may find it big. I would rather have a slightly larger size with bigger numbers. Biggest plus is time SUPER easy to read. I'd love to be able to turn date off and only have time display and nothing else in some mode. I don't need to check the date 6 times a day. Love to have mode where I press one button, upper left say, and date shows for five seconds or something. Indiglo about the same as old big Ironman 100, excellent--when it doesn't break which it almost always does. I have many of these watches where the time still shows but Indiglo never works, Timex themselves admitted to me this is a known problem. The rounder face, versus rectangular, better looks, but wonder if it is optimal way to make most readable. I would pass on this watch. I have always liked Ironman watches, but the branding is so bad, glass especially, and the absymal quality of Timex Indiglo, are unacceptable.

Cool & functional
Color: Pink
Attractive watch. Simplistic, yet cannot understand everything without not having instructions. Watch did no come with instructions, which became hard to figure out all its functions.
