Customer Q&A - Atro HL00-64001

On different types of applications of different tractor on a hood hold down strap is there a manufacturers specifications on the weight of the hood on sudden forward stop or a rear end collision to hood that from flying off. - I was told that a bungee cord would be the same as a manufacturers spec's.

I am unable to get the manufacturers specification on the break strength of the stock hood latch but I did speak with Atro on this. An Atro polyurethane hood latch will have a higher break strength than the original rubber strap by a factor of three and it will be much stronger than a bungee or tarp strap as well as much more resistant to weather and oil. The other thing to consider is that a bungee cord may not be a DOT inspection fail but it may inspire a DOT officer to look closer to see what else is missing on the truck.


ATRO Engineered Systems (ATRO) is a supplier of heavy-duty proprietary polyurethane suspension parts designed to deliver longer-lasting performance and reliability. ATRO’s free-rotation bushings with proprietary polyurethane material deliver longer life, lower cost-per-mile bushings that are superior to standard rubber or other polyurethane bushings. ATRO bushings are manufactured in the U.S.A and have proven to last three to five times longer than standard rubber and polyurethane bushings.

ATRO’s free-rotation design allows the inner piece to rotate freely, eliminating bushing “wind-up” and allowing less stress on the bushing material and ultimately the suspension components, thereby helping to prevent premature failure.

ATRO Bushings:

  • Meets or exceeds OE specifications
  • Eliminates bushing “wind-up”
  • Installs easily and requires no maintenance or grease
  • Resists contaminants such as road salt, grease, oil, acidic cleaning solvents, hydraulic fluid, diesel fuel, and more
  • Provides a longer life – up to three to five times longer than traditional rubber bushings
  • Enables the suspension to operate as designed to minimize premature part failure

ATRO Engineers Systems’ patented designs, state-of-the-art manufacturing plant and extensive aftermarket distribution network make them an industry leader developing products which improve performance, eliminate downtime, and help control costs.
