2000 Mountain Max Update Kit
W-Arm Relocation on the Rails
(shortening the distance between the rear and center shocks)
Pros and Cons
The kit DOES provide the optional hole in the template to relocate
the front W-Arm back further on the rails.
W-Arm relocation (set back) is a simple task! You don't need a kit!
W-Arm relocation has NOTHING to do with approach angle!
PROS
CONS
- Rough ride. By moving the
W-Arm rearward without installing 2000 style transfer rods and relocating the Rear scissor
suspension, the suspension will bind. This causes BUCKING, BINDING, BROKEN SUSPENSIONS and
BROKEN AXLES.
- The 97 through 99 Mountain Max has a shock & spring combination that was designed to
have the W-Arm in the stock location on the rails. Load balancing is key. Aftermarket
W-Arm relocation (shortening the distance between the rear and center shock) has a
negative impact on the snowmobile's ride!
- Yamaha's 2000 Mountain Max has a DIFFERENT Front Arm, Spring,
& Shock, NOT just relocated 99 parts. In fact, the arm is no longer a
"W"-Arm, It's an "H"-Arm. The shock has been updated and is of much
high quality. It also changes the shock angle (which is not possible with the W-arm.
Yamaha designed a new shock to prevent damage to the Shock, Arm and
Tunnel. This becomes a HUGE concern when the 97-99 W-Arm is moved back.
- W-Arm relocation requires elimination of the front set of bogie wheels. This causes
excessive hyfax wear. The 2000MM's H-arm allows these wheels to be used.
- Testing at Mountain Performance revealed tunnel crushing
under extreme riding conditions with the relocation (we were concerned about this from the
beginning and used large stainless patches inside and out). It just wrinkled the tunnel
forward and upward of the patch. It is not feasibe to strengthen you stock tunnel to
accept this relocation.
- Our 2000 Update kit (when installed w/o moving the W-Arm back on the rails) moves
the W-Arm, Center Shaft and Rear Shaft back equal amounts (not upsetting the design
characteristics of the suspension). Further, the front W-Arm still bolts through the Bulk
Head and Tunnel (not just the tunnel). That means no reliability problems.
We recommend a good set of adjustable weight transfer rods
in place of the W-Arm relocation. See the
Adjustable Rods
sold here!
If you still want to relocate, we have a Chrome Moly and Aluminum H-Arm & Powder coated brackets. Call for details. Call for details.
* Not to mention ELIMINATE the possibility of being towed home (like an
Arctic Cat) with a bent shock shaft or wrecked tunnel.
