Jason Grimes' Custom Suspension Mods

If you've been following STREET RODDER for the past year, you've undoubtedly taken notice of some of the work coming out of The Garage--Jason Grimes' shop in Lebanon Junction, Kentucky. We've covered some of his customer builds as features, plus we've followed along as he's created some interesting suspension setups. Well, he's at it again.


This time Jason, who happens to like the way quarter-elliptic springs look and work, put his know-how into triangulating a set of those springs with a tube axle front suspension. As always, he works out his theory on paper first, then as a 3-D model in cardboard to see if his ideas have merit. Once satisfied with the outcome, he starts fabricating the necessary parts and pieces.

This particular suspension is going under a '34 Plymouth coupe, for which he has already created a set of custom framerails. The spring he's using is a set of quarter-elliptics from POSIES, but he basically builds everything else he needs himself. So follow along and see how it's done!
