About KW Variant 4 (V4) CoiloversHigh-performance racing technology for daily road use with KW 3-way racing damper adjustment technology
With the new KW coilover kit Variant 4 with its coilover struts made of stainless steel, you will give your super sports car the necessary reserves to further increase the driving dynamics. The three way adjustable high-performance shock absorbers with their independent adjustment of the rebound and low speed as well as high speed compression damping are based on the successful racing technology of the multiple overall winners of the ADAC Zurich 24h Nürburgring and depending on the vehicle-specific design, they also feature aluminum top mounts. The new KW coilover kit Variant 4 is developed exclusively for selected high-performance vehicles, which can be driven more safely at the driving dynamics limit with our KW suspension technology.

Setup – factory-set pre-configured damper setup with separately 3-way damper adjustment
The three-way adjustable high-performance dampers with the independent setting of the rebound stage by the “TVR-A”-technology as well as the low-speed and high-speed compression stage damping by the “TVCLH-A”-technology are based on the successful racing technology of the multiple overall winner of the ADAC Zurich 24h Nürburgring race and are depending on the vehicle-specific version, braced with aluminum top mounts. The new KW coilovers Variant 4 are exclusively developed for selected high-performance-vehicles, which due to the sophisticated KW suspension technology can benefit from safer driving at the limits of their driving dynamics.
TVR-A rebound stage damping (Twin Valve Rebound – Adjustable)
The two-step, patented “TVR-A” technology enables the small volume to flow through an adjustable, conical low-speed bypass in the case of slow damper speeds, while in the case of higher piston speeds, the main rebound stage valve opens for the large volume flows. This provides a big improvement in terms of ride comfort without influencing the high-speed in the safety-relevant range. There are 16 precise clicks available for individual settings, so you can choose between more comfort or more body control.
TVCLH-A compression stage damping (Twin Valve Compression Low Highspeed – Adjustable)
With 6 precise clicks in low-speed and 14 precise clicks in high-speed range of the compression stage damping, the cross sections in the valves are decreased or increased, in order to achieve either more or less compression stage damping. The “TVCLH-A”-technology has a blow-off characteristic with large cross-sections which allows high low-speed forces for an optimum bracing of the vehicle body without raising the body in the case of wheel-induced high damper speeds (driving over curbs). The separate low and high-speed setting is always supplied with an additional rebound setting (“TVR-A”-technology) for an in dependent 3-way damper setting.Models

15 Pack (WA0010)Replacement Trimmer Line Spool C
This weed eater trimmer line is pretty tough. Although there was only 12 spools in the box, but the Description says 15 spools, And this trimmer line is a lot tougher than the previous line I was using. I used very little of it on the first spool, which is great these Worx trimmer line spools fit perfectly and function perfectly this is a great product to purchase, and I will highly recommend them. if you just have a small amount of weed eating to do I would recommend getting these spools for your worx weed eater.

Good product for the price
I bought for my Worx trimmer and they work great. Even though Worx offers free replacements, when you add shipping onto the "Free" order..it costs more...this price is well worth it.

String breaks about halfway
Just as pictured. PROBLEM…..LINE BREAKS ABOUT THE MIDDLE OF THE SPOOL…. Wound so tightly that once you have used the first half it is impossible to use the rest…. So guess what…I have to buy more!
