Product Description

MPSS Idler Suspension Unit

[Patent# US9,333,436 B2]

Non-assembled Suspension Idler for scale vehicles [i.e. 1/6 scale or larger]. This unit of TWO IDLER SYSTEMS is over-designed for a swing arm type suspension system, for the purpose of tensioning the tracks. The NEW idler now has 3/8" bolts on both sides of the hull/wheels, not allowing any lateral torque.

This self-standing suspension unit consists of a road wheel shaft, connected to a layered swing arm, which is connected to the swing arm shaft with an adjustable tension coil spring. Each suspension unit is rotating inside a steel square tube rail (included).

The semi-moon groove extension is used for fine tuning the suspension tension. The suspension arm should be inclined 45 degrees downward toward the back of the vehicle.

Internal Floor print of unit: 5.5 cm width (2.1") by 6 cm length (2.4"). The height of this unit is only 5.4 cm (2.25")

Advantages:

    • Flexible: Each suspension unit is independent from the other units. They can be positioned at different locations, combined in sets of x4, x6, x8 or even x16 for Scale German Tiger and Panther or Allied Cromwell or T-34 tanks of WW II.
    • Strong: A series of suspension units across a steel rail will increase the structural strength of the vehicle. This suspension can be mounted on frames such as Plastic, Fiberglass, Aluminum or Steel.
    • Powerful: The coil springs are rated for 8.6 kg (19 lbs) for each unit, which allows for 136 kg (300 lbs) loads for a set of x16 units.
    • Adjustable: Two adjustments are possible on this suspension unit: The coarse adjustment is made on the position of the hex bolt connection between the swing arm layered plates and the swing arm shaft. The fine adjustment is made on the tension plate connected to the coil spring tangential arm.

  • Coil Spring with tangential arm ("right-hand AND left-hand" spring)
  • Two 3/8" ID Swing arm sleeve with four 5/8" OD bearings. 3/8" bolt with nut
