Your frame is the “spine” of your vehicle. The frame design most common to heavy-duty trucks resembles a ladder, complete with cross-members and side rails. To satisfy the wide variety of trucking performance applications, engineers have toiled to design frames just right. Your frame should be strong enough to handle expected loads, vibrations and shock–yet flexible enough to resist bending and twisting forces.
The side rails of your frame support “vertical load” and “side load,” which include your engine, transmission, suspensions, fuel tanks, and more. The cross-members, which support your engine and transmission (among other major components), offer a “torsional stiffness” that impacts the comfort and performance of your truck. Cross-members also prevent your side rails from twisting with side loads.
Frames are generally made of steel but can be made partially or wholly built of aluminum to reduce weight and increase fuel efficiency. Most trailer frames use a unibody or monocoque design. In most heavy-duty vehicles, the extreme front and extreme rear of a frame rail bear less stress than do the middle sections, which take the greatest beating.
Aftermarket Modifications and Frame Alterations
We offer specialized equipment modifications, including dump boxes, rack bodies, lift gates, and snowplows.
An important consideration for upgrades: additional equipment will affect the loading of your chassis frame. Sometimes it even becomes necessary to reinforce the frame.
Also keep in mind that any modification done must not exceed GVWR (gross vehicle weight rating) and GAWR (gross adjusted weight rating).
Provincial and federal requirements may also come into play with modifications since upgrades can affect vehicle certification for noise emissions, brake requirements, noise emissions, etc.
At Vancouver Axle and Frame, we make sure your product is durable, well matched to your vehicle, and meeting all NSM requirements. Contact us NOW with your modification needs!
