Mod-Lite
Speedway Engineering has an innovative rear end housing that's ideally suited to most short track applications. It's built for optimum performance, reliability and economy.

We've taken the technology proven on Super Speedways in Goodys Dash Series competition and incorporated it into a special lightweight rear end setup that's ideal for cars up to 3,100 lbs. They come with .188" wall, 1020 DOM tubing and can be optionally fitted with lightweight, strong chrome moly tubes (.120" wall). Likewise, you can substitute lightweight hollow axles for the "solid" premium alloy steel axles.

The MOD LITE FLOATER with optional features weighs about 76 lbs. and is 16 lbs. lighter than our popular Grand National Floaters. Through reducing unsprung weight you can enjoy significant performance improvements with quicker lap times. Go to the head of the pack with MOD LITE!
