Dana Corporation has announced that it will supply full-perimeter frames, as well as thermal-acoustical protective shields (TAPS) and power steering hose assemblies, for General Motors’ 2005 Hummer H3.

“The Hummer name demands a high level of respect for its rugged performance, and Dana is honoured that our technologies are part of this unique vehicle,” said Michael J. Burns, Dana’s chairman and CEO. “We are proud to continue our long tradition of working with GM to deliver products that excite consumers.”
The ladder-type, fully welded frame — made of high-strength steel — features superior stiffness over previous generations of frames, Dana says. It also has mounting and suspension brackets that are simultaneously pierced to provide a more precise merge between the frame, body, and suspension. This enhances sight lines and vehicle ride while reducing noise, vibration, and harshness (NVH) the company claims.
Dana also provides a three-layer exhaust manifold TAPS to manage heat and lower engine NVH. The shield’s low-mass design consists of top and bottom steel layers with fully hemmed edges for safe handling along with a center insulating damping layer for improved NVH.
Dana’s power-steering hose assembly includes the pressure and return lines, along with a single-point connection to the steering gear. Dana says the new system decreases the number of potential leak paths by replacing brazed joints with formed tubing. A second o-ring has been added to the initial o-ring to further improve sealing performance. Compared to traditional systems, this version reduces NVH levels without adding cost, the company says. Dana jointly developed the assembly with GM and Mando, the steering gear supplier to the H3.
