Gents,
The Bilstein shocks that come with our Recon Series and HD Leveling Kit are different than those sold by Geno's. Although visually similar, the front shocks are a different part number. KORE coil springs provide significant droop travel. The Bilstein 6681 sold by Geno's will not work with our kits as they are too short and will top out while traversing medium-sized bumps. However, the 6681 will work well with the OE coils and should work with most puck-style spacer kits.
At one time, the rear Bilstein shocks we sold with our kits were custom-valved. KORE worked with Bilstein to develop valving that incorporated a one-way check valve to maximize rebound control while minimizing compression damping. In a few months this exact valve profile will be offered by Bilstein in their 6647 shock. I have been told that it will retain the original 6647 part number with the addition of an alpha-numeric rev designation to indicate the new valving.
Since the first of the year KORE has not sold revalved 5100 Series shocks used in the rear of the Recon kits. Today we use a different shock with a soft linear instead of a digressive valve profile. To reflect this change, the price of this kit was lowered on 3 Jan. 2006.
Besides causing stocking problems, there are several reasons why KORE no longer parts-out systems, the most important of which is that the components in our systems are designed to work in concert. Since KORE prioritizes function, mixing components with differing performance parameters doesn't make sense. It would be like installing a high-flow exhaust while retaining a restrictive intake. You may save some money, and the truck will sound different, but the modification won't yield significant performance gains without addressing the motor as a whole.
As new designs become available, KORE does sell upgrade parts to prior customers. Our database or their invoice shows what system they have, we know what's compatible with what and we know that as prior KORE customers, they're on The Team.
KORE would probably increase profit if we sold all of our parts separately, but we're not interested in this kind of opportunism; we're interested in long-term reputation - and that revolves around balanced performance. Which is why KORE matches complete suspension systems to driving requirements, instead of just selling a variety of parts to whomever wants to purchase them.
In the long run we've found that everyone benefits.
Best Regards,
