XTX linkage kit for rear suspension
* Dollar conversion US-Canada is closely the same these days.
rear suspension of the Apex and Nytro XTX has a poor
progressivity and a lot of friction. The suspension is stiff on small
bumps and bottoms out easily. In addition, the suspension is
sagging a lot, so we lose valuable travel.
The kit greatly reduces
friction in the suspension and makes the progressiveness of the
suspension more efficient. The snowmobile stands higher on its travel
comfort and better bottoming resistance. In addition, the
snowmobile gets better weight transfer during acceleration without
affecting its cornering behavior.
See the installation instructions here.
graph shows the difference between the original setup and the linkage
kit. We can notice that the kit stays longer in the comfort zone
between the dashed blue and purple lines.
The kit also maintains the
sled higher (crossing with the dotted yellow line) without the
suspension becoming too stiff at 2/3 of the travel.
Rear Shock Pull-Rods
rear shock Pull-Rods for Nytro XTX and MTX (except MTX SE),
Apex XTX and MTX, Vector MTX, RS Venture and Venture Lite.
Much stronger and nicer looking than original parts.
Lowering, rebuilding and revalving shocks:
improvements. Lowering and revalving the ski dampers can significantly
improve the handling and cornering of the snowmobile on the trail.
Steering effort is lighter and skis stay flat when turning. Cornering
is more intuitive rather than calling for a deliberate effort.
The rear shock absorbers recalibration allows great
improvement in comfort without increasing bottoming of
on large bumps and holes.
Rebuild only: 60$ per
Rebuild and revalve: 80$ per shock
Shock tube reinforcement
absorbers with an auxiliary reservoir connected with a rubber hose on
Yamaha models have
a defect: the walls of the tube of
the shock are too thin, they swell and burst after repeated blows
(Nytro XTX 2009-2010 rear shock, Nytro RTX 08-09-10 Center shock, 09-10
Venture GT rear shock).
We install a reinforcement tube on the lower
part of the shock absorber to prevent this problem. Considering the
value of a new shock, we strongly advocate installing this
your shock is at risk.
Yamaha has corrected the problem in 2011.
35$ plus reconstruction
SOQI shock GYTR
Sometimes there is buildup of
corrosion around the o-ring of the compression adjuster needle causing
an oil leak on the dampers so equipped. We then must rebuild or
re-calibrate the shock and polish the chamber of the needle.
Disassembling, polishing and o-ring change: additional 10$ per shock
Needle replacement: 45$

2nd generation of our rear
spring cam: Lighter and cheaper
These cams are machined from aluminum.
The cam that we propose offers 5 positions:
1 = soft on the stock cam
2 = medium on the stock cam
3 = hard on the stock cam
4 = one
5 = two notches firmer
For installation, lift the rear of the snowmobile or flip it on the
Unhook the front of the springs and let them hang on the side
of the snowmobile.
Remove the snap ring of the cam.
Change the cam and go in reverse order.
is recommended to strengthen the support rod cams on the Venture Rs
2005. There have been reports of a few broken support rods
with the original cam.
