TCP Bumper...Dollar for Dollar best mod for the IQ-RMK's
I dont understand this bumper kick a lot of you are on. The bumper on the dragon will push over small green things no problem. Now if your hitting something that is going to make the sled stop suddenly, where is the energy from impact going? A plastic bumper will help absorb that energy. The metal is going to let your aluminum bulk head absorb it.
T4T... I can understand where you are coming from, and the logic is good but I don't agree with your evauation.
If it were just a matter of replacing a bumper or lifting the sled in a different way.... no problem... but the real world of mishaps plain happens.... getting bucked from your sled on a good hill climb and hittng a tree, hitting a ditch, find that rock under 3 feet of fresh pow, hard boondocking etc...
T4T is dead on with the energy absorbtion. Why do you think they make crush structures on cars, race cars and so on? To absorb energy to protect the driver or the main part of the vehicle. The TCP bumper will withstand more impact, no question there. It will however be more determental to the blukhead/chassis though when you compare the two. Pick your poison with this one. I will keep the plastic stocker and replace as necessary.
Although there are cars out there with sacrificial designs, the Polaris IQ's dont have this feature. In a car, the "crush structure" is desgned to absorb impact and protect the driver, who is strapped into the car... the crush structure is designed to totally sacrifice the chassis to protect the driver.... on a sled, hit something and watch how far you fly!!
The TCP bumper will actually tie together and help to reinforce the bulkead on your RMK.
The bumper/fender/panel assembly on the IQ is just plain weak. The bumper itself is held to the fenders by 6 small screws (#9 and #12 in the diagram below), the fender has just small nibs for these screws to mount to. I have personally watched 2 different IQ-RMK's (a 2006 and a '07 Dragon) get their bumpers ripped out and part of the fenders plus hood damage when people were getting their sleds unstuck in west coast snow... Polaris is
ALSO in the business of selling parts... and they make a very tidy profit doing so.
I have the bumper on my sled, I was the first person to get the production version. Trust me, before I lay down my hard earned cash, I do a lot of looking into the pros and cons... From the perspective of my engineering degree and 20 years of fabrication and mechanical installation experience. Before I added the TCP bumper I had broken 2 sets of plastic bumpers and fenders + other stuff from minor wrecks. If you hit anything hard enough to bend an IQ-RMK bulkhead with the TCP bumper installed, you would have done a lot more $$ damage to the sled than just bulkhead/tunnel assembly costs on a 2007-2008 RMK (which, by the way is only $1049.00).
If you center-punch a tree on an IQ RMK with a stock setup at anything over 10 MPH and you will take out the plastic bumper ($42) the nosepan ($210) The front screen ($34) The air-dam ($78) The right fender ($157) The left fender ($157) The exhaust Pipe ($305 stock or $600 for aftermarket) The hood hinge ($45) Misc springs, rivets etc (about $60).
If you can do the work yourself, tear off a whole weekend for this work, 1-2weeks to get the parts in. If you have to pay a shop, tear off another $600 - $800 for the repairs... not to mention the tow out and lost riding time.
Now this is not a complete list, if you hit something harder, you will break hood, the enginge loose, trash the mounts, airbox etc...
I know this from actual experience.
If you WERE to bend the bulkhead with the TCP bumper installed, you would have bent the bulkhead anyway in your stock sled (no TCP bumper) and ruined a lot of other stuff as well.
According to Mike Vanamburg, a specialist in snowmobile chassis fabrication, as well as Mark Holz, the Polaris IQ-RMK's are the strongest bulkheads out there.
Clicky for the link to TCP's website bumper page. http://www.tricityperformance.net/eshopprod_cat_2332-18092-18093-24214_product_333681.IQ_FRONT_BUMPER.htm
It is one of the best pieces of fabrication out there. Not a simple item to make as some have been suggesting. Theres at least 2 hours of welding and a good amount of aluminum in the bumper (expensive these days) plus countless hours of fitting and R&D on this setup. All jig welded and Very, Very sturdy!
Some have commented on the price, but if you see the fabrication, the completeness of the kit and the homework that went into this, you will not object to paying the same as you do for a pair of PLASTIC skis or pipe for your sled.
The hood hinges just like stock with the TCP bumper kit. Install was very straight forward with good instructions. About a push for wieght compared to stock and you remove all of the heavy plastic stuff.
This is not just an aluminum tube that is bolted to the bulkhead... more like an Extension of the chassis that protects the pipe and hood in the event of a bump with a tree (doesn't take much on an IQ to cause $1000 in plastic/engine damage) or "finding" those early season stumps or rocks with your new RMK.
If you are running a Turbo on your 600/700/800 I would consider this piece of protection MANDATORY to keep everything together. If you hit something without the TCP, get ready to watch that new Garret or Aerocharger pop thru your nice new stirrup vent.
Unlike the REV XP's.. The IQ's do not need a sacrificial front end to protect the others. Any hit big enough to cause damage to the bulkhead with the bumper installed would destroy the bulkhead anyway... and take a lot more with it.
I've seen some IQ RMK's stuck in deep snow and had the bumper pulled off from trying to get the sled unstuck. Floatation is still very good with the bumper installed. The nosepans are not needed on this chassis to keep the sled above the snow.
I polished mine, but the coating that TCP applies to these bumpers is much better at keeping the ice and snow from building up.
IMO, Dollar for Dollar one of the best mods you can do for your IQ-RMK. (And yes Rob, your [L=Better-Boards]http://www.f-bombracing.com/BetterBoards.html[/L] are an awesome mod as well)
For those that will ask, NO, TCP does not offer the bumper in Polished finish, I stripped mine, sanded and polished it... what a PITA. I would not do it again... too much ice, then snow sticks to it, powdercoated is better and my next bumper will stay that way.
