With an experience in shock-absorber designing and manufacturing for many years, KONI, leader in Heavy Duty dampers (buses, trucks, trailers, military applications, railway, etc. ...), has decided to combine its high level of technology and its 4x4 market knowledge to create a new range of dampers dedicated to the raiders.

The main features of the new Heavy Track RAID series are:

Twin-tube technology
- Outer tube thickness of 2.5mm.
- Damper function guaranteed in case of deformation of outer tube by impact of rocks. 
Reservoir tube:
- Big bore (70mm)
- Oil volume has been doubled for better cooling & efficiency
Attachments:
- Solid, robust attachments
- Attachments welded all around (360°)
Adjustability:
- Possibility to adjust the rebound forces in order to adapt your damper to your springs and / or loads and so increase its life-span.
Double dynamic protection:
- Rebound: progressive hydraulic rebound stop valve
- Bump: extra security in case of big compression impact 
Easy fitting:
- Heavy track shock absorbers make use of original attachment fittings. No vehicle modifications are  necessary.
The Heavy Track Raid shocks are reliable high quality replacement performance parts for customers who seek a non sophisticated but effective product to do the job it's designed for; to finish in off road rally raids.

1 Heavy Duty attachments, suitable for all (off)road-conditions
 
2 Bump Stop
 
3 Special extra-heat resistant Viton seal
 
4 Teflon piston rod guide
 
5 Hydraulic rebound stop
 
6 Piston rod diameter Ø18mm
 
7 Teflon piston-ring
 
8 Adjustable rebound forces for individual fine-tuning
 
9 Bigger reservoir and more high-performance oil to improve heat exchange
 
10 Oil Baffle
 
11 Reservoir diameter Ø70 mm
 

KONI shock absorbers have a built-in hydraulic rebound valve with spring. This rebound valve substantially increases the damping forces during the last 40 or 20 mm of the rebound stroke to prevent metal-to-metal contact.
