I am looking at tunnel extensions on TracksUsa for my 2001 SRX. If I extend it, will I have to purchase a longer track? 136x15x1.25? Whats the biggest lug size you can fit onto this sled safely? 1.25? 1.5"? Thanks for the help guys. Its only $110 for the extensions!

tunnels ext. has nothing to do with the track, rail ext. does, but generally people put on tunnel ext. because they extended the rails. track usa usually has complete kits rail ext, track, and tunnel ext. my friend just did his sc10III for $600ish, you can get an 1.25 in the srx without studs by removing the exchanger protectors, otherwise you need to drop to 8 tooth drivers wich may also require a gearing change depending on what type of riding you do, now your pushing a grand
