Default SOLD - Koni 8242 (aka TC Kline) double adjustable shocks

SOLD - 10/17/2012

I'm selling my Koni 8242 double adjustable shocks. These are also sometimes known as "TC Kline" shocks. These are *not* just revalved Koni Yellows -- compared to Yellows, the 8242s have much larger shock bodies and shafts, and were designed as double-adjustable shocks from the start, instead of being converted to doubles after the fact.

My shocks were rebuilt and revalved by Jeff Wong at ProParts USA in August 2010. They were repainted standard Koni yellow as part of the rebuild, in case you're wondering why they're not white like other TC Kline shocks. I took the shocks off of my car in June of this year after winning the San Diego Tour on them.

It's a pain in the behind to adjust the left rear shock, so I had a low profile adjuster custom fabricated. It stays on the shock at all times (although it's removable), and makes adjusting the shock somewhat easier.

Full disclosure 1: The brake line mounting tab on the front shocks interfered with large aftermarket sway bars, so I cut it off. The paint used to cover the spot where the tab formerly attached doesn't match the rest of the shocks. This is visible on the leftmost shock in the picture.

Full disclosure 2: 8242s clunk when cold. This is not indicative of a problem with the shocks -- they all do it. Whether you care depends on how sensitive to NVH you are; I find it annoying, but I also run a stock exhaust because I find even aftermarket doubles too noisy.

Comparable double adjustable shocks from Penske, Moton, JRZ, and AST are well over $3000 new. I'm asking $1400 shipped or best offer.

I can be reached by text (four-2-five-7-six-1-three-1-four-8), email (my name as listed in my signature file, with no space between my first and last names, @live.com), or PM.

Thanks for looking!

I have the same shocks and was running 1000/850 f/r and never turned the knobs past half way.

Stephen should chime in here to let us know what kind of revalve was performed. My shocks that were also rebuilt by pro-parts had low speed rebound added to the shock, which makes the shock work a good bit better for autox applications (especially in stock class) than they did with the regular TC Kline damping.

The rebuild on these isn't cheap, you are getting a better shock than the regular TC Kline 8242, and hence the higher price than what the other shocks have sold for recently.

Unfortunately, I don't really know. I had the shocks rebuilt immediately after I purchased them just so that I wouldn't need to think about them potentially wearing out. I hadn't run on the shocks at all, and thus didn't know if / how the valving could be improved. Jeff from ProParts said that he'd give me the same valving as Joey Schilling (third in BS at Nats in 2010), and I said that sounded great to me, so that's what I got.
