The main rails are fully boxed from laser cut metal pieces that are welded together in special jigs-which means that these are not like the factory 'C' channel rails, but rather a four-sided rail (often called a box rail)-so we thought mounting reproduction pre-bent fuel and brake lines would be a challenge. We were wrong. The lines went right on the frame like they were meant to be; the only thing we had to do was drill and tap some holes to mount some hold-down tabs.
Other than that, the various systems bolted right on the frame and everything looked great when everything was reinstalled. The owner of this vehicle is very excited to get it back on the road and enjoy the better-than-new performance of his beloved Corvette (a car his dad drove for many years and now is ready to once again be a longstanding family heirloom).
Without a doubt, swapping frames is an involved job, but if you have a rusty frame and want to enjoy safe, durable miles with your Corvette, you have to replace the frame. It's a tough choice, but one of those tough jobs that will pay dividends for years to come.
Collier Technologies Frames
The men behind Niagara Falls-based Collier Technologies, Bob and Rick Collier, are both Corvette enthusiasts. The engineering and manufacturing side of Collier Technologies, Davert Tools Inc, started in 1996, but these guys have over 20 years each supplying assembly line equipment as a Tier 1 automotive supplier to the OEMs including most GM plants in North America (including the Bowling Green Corvette plant).
Their frame business started many years ago when Rick needed a new frame for one of his vintage Corvettes and couldn't find one-so the brothers decided to build their own. Like most car guy projects, the frame building program was soon an over-the-top project utilizing Davert Tools engineering and manufacturing as well as other resources to build a frame better than the factory piece. Other than being fully fabricated, the Collier replacement frame has been through extensive simulated durability testing to ensure it can handle the rigors of being driven for thousands of miles.
While their journey to a final product was lengthy, we think it was worth the effort as every Collier Technologies Corvette frame is a fully-boxed work of art in its strength, mounting point accuracy, suspension flexibility (it can be set up to mount late model Corvette suspensions under an early vehicle) and appearance.
As a heads up, the Collier frame is slightly different from a stock frame, but once we spent some time with it, the appearance and functionality of their frame won us over. In the end, we would recommend the Collier frame for someone who plans on driving their Corvette like a regular car and wants late model rigidity and functionality in their older Corvette.
