Product Spotlight


The Volvo T-Ride® suspension is for both on- and off-highway applications. It features a parabolic tapered spring pack that is upside-down and mounted outside the frame rails. There is a cushion that sits on each axle that is bolted to the end of each spring to absorb shock and vibration. Four lower torque rods control braking and acceleration forces. These suspensions are popular on waste haulers.

Benefits of ATRO Components

ATRO's T-Ride® components are chemically resistant to the common contaminants that most fleets face.

All T-Ride® torque rods and V-rod bushings have rotating pins for easier installation & elimination of torsional stress.

Load Spring:

  • Proprietary polyurethane formulated to absorb shock & dampen vibration improving ride quality

Lower Torque Rods:

  • Complete fixed length & adjustable torque rods, all with rotating pins for easier installation
  • OE lower torque rods rebushes with rotating TS96-22700 bushing for easier installation

Upper V-Rods:

  • TH96-22200 apex bushing uses a low friction, high abrasion & wear resistant polyurethane for durability & longevity
  • TS96-22600 & TS96-22286 end bushings have a split outer sleeve to ease installation & conform to inconsistent eye sizes

Product Spotlight


Mack Pads are manufactured using ATRO's proprietary polyurethane. The characteristics of this ATRO Poly formulation is Shock Absorbsion.

In contrast, rubber Mack Pads and other polyurethanes are made with a high rebound material. With the high deflection rate of this material, it can cause vibration and road shock. This energy can transfer to other suspension components, trunnion assemblies and the cab.

Positive Effects of ATRO Poly in Mack Pads:
  • Low Rebound, No Bounce Material
  • Shock Absorbing Material
  • Chemically Resistant to Contaminates
ATRO’s proprietary polyurethane takes the bounce out and acts to absorb shock, resulting in:
  • Smoother Ride
  • Longer Life and Extended Life of Attached Parts
  • Less Cab Damage
  • Reduction of T-Leaf Failure

PROGRESSIVE LOAD SPRING

ATRO Part LP50-24778

In July 2014, Hendrickson began using their progressive load spring on all new production vehicles with the Haulmaax suspension. The overall height of the Progressive Load Spring is 4 1/4” in comparison to the Auxiliary Load Spring height of 3 5/16”. Because of the increased height of the progressive load spring, two auxiliary shims are typical instead of the 3 shims used on auxiliary load spring. When either load spring’s unloaded height measures less than 3”, the spring needs replaced.

ATRO’s Progressive Load Spring LP50-24778 is designed and engineered to be compatible with ATRO’s LP50-24179 Bolster Spring, providing maximum control and suspension performance. ATRO recommends removing or adding load spring shims (ATRO MS50-29791) to achieve the desired level of control and ride. Please refer to ATRO Progressive Load Spring Installation Instruction #DC001-022615. ATRO’s Progressive Load Spring will maintain contact with the shim plate at all times.

Note: In all cases, there must be at least one shim present per side.

ATRO’s Progressive Load Spring will replace the OEM load spring on newer trucks and can be retrofitted on older models to improve the suspension performance.

ATRO’s polyurethane material, coupled with ATRO’s design and engineering, will provide the fleet with:

  • Superior strength and durability
  • Resistance to chemical attack
  • Improved suspension performance and life

The LP50-24778 is also available in the following ATRO suspension kits:

Product Spotlight


Many concrete mixers employ a rear mounted “Stinger Axle” that drops down and makes contact with the pavement, usually powered down by a hydraulic cylinder. These “Booster Bridge Trailing Axles” are forced down to shift the load forward towards the front of the truck. This allows concrete mixers to maximize payload and meet local weight restrictions by improved weight distribution across the truck axles. These “drop down” axles on the rear of the mixer are often rigid suspensions. Being rigid they take a beating and ATRO’s stronger polyurethane material provide much longer life for the booster cylinder bushings mounted at the end of the cylinders. The EB38700 BridgeKing cylinder bushing has an extended outer sleeve to reduce cracking. Please see the diagram for the bushing locations.

There are several manufacturers of these suspensions. The following bushings are on popular applications:
  • ATRO #EB38700
  • Con-Tech #750051
  • Kimble #C9634375-03
  • BridgeKing Cylinder Pivot Bushing
  • ATRO #EB38651
  • McNeilus #0183488
  • McNeilus Booster Cylinder
Benefits of ATRO's polyurethane bushings.
  • Polyurethane material is twice as strong as rubber
  • It has 3-5 times the life of rubber bushings
  • Polyurethane is not affected by chemical attack including acidic cleaners

Wear Items:

Tri-functional bushing

  • Mode of failure: bushing tube spacers melt, inner sleeve separated from rubber.
  • Cause: excessive vertical movement of suspension arm caused buildup of excessive heat.
  • Note: check to see if tires are out of balance or if shocks have failed.
Tech Tip:

ATRO's installation tools will install/remove OE bushings and/or ATRO bushings. Remove the alignment pins when installing/removing the ATRO "Easy Install" bushings which don't have voids. Conversely, the OE tool can be used to install/remove both OE and ATRO; simply remove alignment pins from the rear drive plate before attempting ATRO "Easy Install" installation/removal.

Installation Tool PT50-59307

Do not use an impact wrench on this tool. Must lubricate before use. Can be used to install/remove ATRO & rubber pivot bushing.

PS011-090117

Product Spotlight


Problem:

  • When the drive axles rotate during braking and acceleration, the standard rubber bushed spring eye bushing will rotate in the leaf spring eye causing the eye to wear and the bushing to become loose.
  • The bushing tends to “walk” out of the spring eye towards the driver or curbside of the truck.
The PB46-26268 Solution:
  • The free rotating inner pin prevents the bushing from turning in the leaf spring eye, eliminating spring eye wear.
  • The inbound flange prevents the bushing from walking sideways out of the eye.

Note: The aftermarket (including ATRO) offers .060 oversized bushings to compensate for the spring eye wear. However, the leaf spring will eventually need replacement.

Note: Failure to properly shim will force the load springs to accept the full load and prevent the auxiliary spring from engaging and carrying the significant portion of the load it is designed and required to carry. This produces additional stress on the load pads and may cause premature failure and could void warranty. Do not mix ATRO suspension components with other manufacturer’s components. Doing so will adversely affect ride quality and may cause premature component failures.

Product Spotlight


Chalmers walking beam-style tandem axle rear suspensions use two large elastomeric load springs and eight large torque rods, 4 upper and 4 lower. This design allows for a large degree of articulation so the load is equalized while keeping the tires in contact with the ground.

ATRO load springs provide key benefits over rubber

  • Resistant to chemicals (lime, corrosive solvents, road wash)
  • Better load handling and ride characteristics than OEM rubber and other polyurethane brands
  • Will not take a permanent compression set like rubber springs, keeping ride height accurate and driveline angles in spec

LP19-24015OEM #1501515,000 lbs
LP19-24026OEM #1502626,000 lbs

ATRO torque rod bushing options:

ATRO’s 2-piece torque rod bushings make installation easier and faster. With limited installation clearance, 2-piece bushings are placed on each dowel pin on opposite sides and ends. Then the rod with the other halves loaded are positioned on the dowels. Finish the repair by placing and tightening the spigot cap.

Tech Tip:

Change one rod at a time! Otherwise, axles will slide and make re-installation of rods very difficult.

  • Rubber load springs, subject to chemical attack will take a compression set over time. This negatively affects the vehicle’s ride height, which puts the angle of the driveline out of OEM specs, resulting

ATRO Bumper Choices

Product Spotlight


Today's typical rubber bumpers do not last very long and may be worn out in six to twelve months. ATRO's polyurethane bumpers have been proven to last as much as 15 times longer than rubber.

THINGS TO CONSIDER

  • Labor Cost
  • Downtime
  • Trailer Damage

Changing out a simple trailer bumper can present a technician with unexpected problems. Many of today’s bumpers are mounted into a sealed bumper frame that contains the stop/tail/turn lamps. Often, a lamp will need to be removed to gain access to the rusted nuts on the inside of the trailer bumper frame. This is further complicated when the lamp is secured with a riveted lock ring, common with the newer LED powered stop/ tail/turn lamps. The bumper removal process usually takes a minimum of 20 minutes and as much as 45 minutes to complete and often the lamp gets damaged in the process.
