Wondering if anyone could help me identify this chassis. It seems to have some JK Products DNA involved, but I can’t seem to find anything on the internet to match.

 

Thanks.

JK Extender chassis.

Thanks!

The JK ‘extended’ chassis I found appears to have a long cutout aspect in the center section. Were these two variations on the same (model) theme?

Yes, there were two versions of this JK 4.5" flexi. One with a slotted center, one with a solid center. These two chassis shown are the early version with the up-turned front ends for the guide lift. The later versions had a straight front with a coined area providing for the guide lift. The revised front design came out during the late '90s. I don't recall any differences in handling for the different front ends. I preferred the chassis with a slotted center because you could stick a screwdriver in it to remove most chassis twists or bends. Locally, we ran those chassis on a trioval with stock car bodies. I would think they would work on hillclimbs & other tracks too.

Much appreciated information!

These were the best 4.5 Nascar chassis on the market in their day. Available in a heat treated and non heat treated version. It’s all I used in the late 90s. I’m pretty sure I still have mine somewhere
