  2. REV-GEN 4 & 5 MXZ Perf. Trail 129/ Renegade 137
    Looking for feedback on what people have used when putting fresh slugs into an 850. Being stuck at home and not sledding this week has me thinking doing some PM. Wiseco has always been my go-to, I prefer a forged slug, but MCB makes a nice looking forged dual ring piston, and then BRP factory...

    I am looking for a pair of cylinders that are still within STD piston spec. The Cyl's I have are just a little too worn out to use with my brand new STD pistons. Trying to keep it a TNT engine instead of using alpine parts. If this doesn't pan out, then I am interested in oversized pistons to...

    Hello All!! Time to start working on the sleds!! I have two 2005 500ss sleds that I've owned for a while now. Love them. Both ate their second sets of pistons at the end of last year (blew top ends on last trip of season). Each engine has around 14,000 miles on the crankshafts. Cranks are...

  6. REV-XP/XS Chassis: Perf. Trail 120-129 Inch Models
    Hey guys, I was just wondering what everyone uses/recommends for a set of pistions in an 800 etec. I just bought my Dad's old sled as he's getting an 850, but the sled has 14000km on the sled and the motor is untouched. I figured I should probably do a top end rebuild to get me through the...

    I tore my 2009 600 Etec apart again after doing a complete rebuild last season (top and bottom end) because of a meltdown. Only put about 300 miles on it since the rebuild. when I pulled the top end apart last week the Pistons looked not so good. I went with wiseco forged pistons and I am...

Since then we have designed a custom piston line and offered these custom pistons to the public that allow their engine to run much stronger and longer than the OEM single ring piston design. This piston line...
