Shock Absorber Mounting Kit

Shock Absorber Mounting Kit consists of the following brackets:

  • 1 x 10mm Left Bottom mount plate for trailer shock absorbers. (passenger side)
  • 1 x 10mm Right Bottom mount plate for trailer shock absorbers. (drivers side)
  • 2 x 40mm Top Brackets.
  • Suit Shock absorbers with 12mm bolts.

The flat place is slotted to suit 45mm to 60mm Springs with 1/2 inch or 5/8 inch U bolts. If using 45mm springs, you may need to slice 15mm off the bottom plate to shorten this plate.



Locate the top bracket so that the shock absorber top hangs towards the rear of the trailer at an angle of 15%. This angle can vary a little however the greater the angle, the less effective are the shock absorbers.

The greater the angle, the less effective the shock absorber becomes.

Folks have told me that these shock absorbers have failed and need replacing. Upon inspection, the outer casting was pitted with stone dints without puncturing the casting.

In this case, shock absorbers do expire once they reach the end of life. The most straightforward test is to remove the shock absorber and compress it, and then decompress the shock absorber. If there is little resistance on any compression stroke, replace the shock absorber.

It’s a good idea to check the bolts, which may also need replacing. Good quality shock absorbers are supplied with replacement bolts.

In a vehicle, shock absorbers reduce the effect of travelling over rough ground, leading to improved ride quality and vehicle handling. While shock absorbers serve the purpose of limiting excessive suspension movement, their sole intended purpose is to damp spring oscillations.

Shock absorbers use the valving of oil and gasses to absorb excess energy from the springs.

Manufacturers chose spring rates based on the weight of the vehicle, loaded and unloaded. Some people use shocks to modify spring rates but this is not the correct use.

Along with hysteresis in the tire itself, they dampen the energy stored in the motion of the unsprung weight up and down. Effective wheel bounce damping may require tuning shocks to an optimal resistance.
