I want to install a tunnel extension on my 08 nytro 121 to 136. Just wondering if there is one better that the other? Ulmer racing or Hartman Inc. Thanks
Can't speak for Ulmer but the Nytro I bought had a Hartman on it. Looks like a nice fit and seems strong.

tunnel ext
I've stretched 2 RX-1's, went with Tracks USA rail extensions and Hartman tunnel extensions on both, great fit and tough.

Ulmer
I just installed a kit from Ulmer. He doesn't make any of it himself. He goes out into the market and gets the best parts from whoever makes them and puts it together in a kit. The kit I just installed on my RTX from Ulmer was Tracks USA rail extensions and a Hartman tunnel extension. I have installed kits on friends sleds from Hartman and I really like the fit and quality of his tunnel extension but I'm not nuts about his rail extensions. The Tracks USA rail extensions are very nice and very durable. My advise is to buy the kit from Allen. You will be happy.
