The Fox 987-24-001 2.5 Performance Series IFP HTO Shock Absorber is a bolt-on shock loaded with position-sensitive technology, vehicle-specific valving, and larger pistons to help improve on and off-road performance. Featuring a type II anodized aluminum body that efficiently dissipates heat and prevents corrosion. The 2.5-inch shock body is made with an internal floating piston (IFP) to separate the shock oil from the high-pressure nitrogen, optimizing damping.
The Hydraulic Top Out (HTO) technology offers usable position-sensitive rebound damping control on and off the pavement. HTO helps to reduce harsh top-outs and increases comfort by forcing shock oil through a secondary shim stack to slow down the shock shaft speed. HTO is particularly beneficial after installing heavier, aggressive tires and applications lifted higher than OEM specification. Bolt-on a pair of the Fox 2.5 Performance Series HTO shocks from Guaranteed Auto Parts to increase damping capacity and ride in comfort with position-sensitive rebound control.

Travel: 10.790
Extended: 29.580
Top Mount: Eyelet
Compressed: 18.790

Favorite turtleneck
I'm a big guy- 5'6", about 385, and I ordered the 4x. It fits perfectly. I love the soft material and fabric, and it's slimming without being uncomfortable. The quality of the material is top notch, and I haven't noticed any piling yet. It also looks great with all of my dress and casual wear, with either khakis or slacks. I wear this under my overcoat for outside, and with a base layer underneath it for inside. Definitely a great value for the money.

Too thin, neck portion too hard to position to sport the classic turtleneck look.
Color: White, Size: Medium
Too thin. The neck won't hold a clean look, the neck portion bunches and double/triple folds and I can't get that cool turtleneck look with it that I had with my first white turtleneck that I loved so much I wore it out. This one doesn't measure up. If you just want this kind of shirt to wear in warm weather it's good for that because it's very thin.
