The Fox 987-24-002 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.

Extended: 23.990

Cheap and does the job
Size: 6 Feet
Seems to be well constructed, it’s a little thinner than I expected, but it passes bass just fine to my SVS PB 2000 Pro.

Great value for high quality lights
Size: 2Pcs 7.6Inch Light Bar
These are really nice lights. Night and day difference between these and the cheap Nilights. They should really try to differentiate these in their listings.
Nice consistent beam pattern and color. High quality build. Power output close to claimed rating.
