Skunk2 Alpha Valve Spring & Titanium Retainer Kit - B/D/H/K-seriesSkunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kits for Hondas B series VTEC, D series VTEC, H series VTEC, and K series iVTEC engines. Each kit includes Skunk2s high quality dual valve springs (single for D series) and race proven titanium retainers that are the result of nearly two decades of racing and engine building experience. Each Alpha Valve Spring is manufactured exclusively from super clean, chrome silicone wire
Skunk2 is proud to introduce its Alpha Valve Spring and Titanium Retainer Kits for Honda’s B-series VTEC, D-series VTEC, H-series VTEC, and K-series iVTEC engines. Each kit includes Skunk2’s high-quality dual valve springs (single for D-series) and race-proven titanium retainers that are the result of nearly two decades of racing and engine building experience.Each Alpha Valve Spring is manufactured exclusively from super-clean, chrome-silicone wire milled in Japan. By using inner and outer springs mated together through a slight interference fit and with differing frequencies, Alpha Valve Springs are able to prevent valve float and maintain valvetrain stability at engine speeds in excess of 10,000 rpm.
Skunk2’s industry-leading Alpha Titanium Retainers are designed to significantly reduce valvetrain mass, resulting in more horsepower and improved valvetrain stability. Similar to Skunk2’s already popular Pro Series Titanium Retainers, Alpha Titanium Retainers feature radius-cut edges for additional rocker arm clearance and reduced weight, strategically positioned lightening grooves, and reduced overall heights for better valve seal clearance and even further weight reduction.
Alpha Titanium Retainers are manufactured using the latest 3D CAD (Computer Aided Design) and FEA (Finite Element Analysis) to ensure that each is optimized for strength as well as for reduced weight. Skunk2 engineers then test and prove their designs on the engine dyno as well as the race track. Once approved for manufacturing, only medical-grade titanium that’s been ultrasonically inspected and certified is used. Following CNC machining, each retainer is then individually inspected to ensure proper hole diameter, taper, and that each are free from machining defects to ensure proper installed valve spring heights and pressures. Finally, each retainer is serialized for your protection, including valuable information, like material batch specifics as well as production and inspection dates.
Skunk2 designs, develops, and tests its entire valvetrain lineup in-house to ensure superior quality and maximum performance gains. During development, each valvetrain component is tested both on the dyno and the road, including 11,000 rpm drag racing engines and 17,000 rpm superbikes. Manufactured from the best materials available, Skunk2 valvetrain components provide exceptional performance, reliability, and quality and remain standard-issue on each Skunk2 vehicle that we build and support

K-series engines that are originally equipped with single valve springs must use a K-series dual valve spring base kit (available separately) and cotters (keepers) from pre-2004 K20A2 engines.
When using Skunk2 Titanium Retainers on 2004 and newer K engines, pre-2004 keepers (cotters) must be used (Honda P/N 14781-PR7-A01). Pre-2004 keepers can be identified by the absence of marks along the top edge (2004 and newer keepers feature laser-etched marks along the top edge). For applications where 2004 and newer keepers are used, Skunk2 Titanium Retainers must be used. Proper retainer/keeper selection is important due to varying angle ratios between earlier and later keeper designs. Use of improper retainers and/or keepers may result in potential engine damage.

It's a good one, buy it.
Size: 16 AWG-100 ft
Actual 5 stars!
OFC, copper stranded wire, takes solder nicely when tinned, stiff and pliable enough to stay bent.
covering melts INTO wire as expected.
I was hoping for a good deal and got one.

Not bad for money. But the spot lens is def a narrow spot
Color: 4.5inch Spot Light, Color: 4.5inch Spot Light
I did a direct comparison to BD squadron pro with spot lens.
Pic one is 1 squadron spot lens, pic two is 1 auxbeam 4.5
Not a pair. Only one light each.
Then the video is 2 squadron pro one with spot lenses the other with combo lens.
Then both auxbeam 4.5.
I wouldn’t buy the spot lens unless you have other lights or just trying to light a narrow beam a long ways. The fill light is not good.
I say the brackets and the finish is on par with BD, not as deep as the XL80 but similar in size.
The BD XL pro is def brighter with better fill even with spot lenses. I would say 4 of these would match the XL Pro at half the money if you have the space for four of them.
But even 4 don’t match the XL80’s. But for 160 bucks it’s a good solid light.

Great quality, and very bright.
Color: 4inch Spot Light, Color: 4inch Spot Light
I installed 4 of these pod lights in the front bumper of my 2009 f150 (2 spot beam, and 2 combo beam), and I am very pleased with the overall build quality, and brightness of these pod lights. Installing them is fairly straight forward once you have them mounted where you want them, and they look great! I highly recommend these lights if you are looking to upgrade the lighting on your vehicle!
The video I have attached is with the amber lens, and the picture with the lights on is without the lens. I prefer to keep the lenses on most of the time since it does add a layer of protection from the sun, and bugs/rocks while driving. I also do prefer the amber color for driving at night compared to the white.
