These are our USA-made secondary (final transmission) reduction offerings for Rancher 420 DCT Auto+ES. Frame decal model designation must include an "A" such as TRX420FA or similar. No internal clearance mods needed but will require VSS(speed sensor) modification by installer or use our modded sensors found in the "Parts" section. Check our install guide page or send us a message for VSS mod details. The reduction changes the speed readings to the ECM so full throttle auto shifting is affected but driveability is retained. If you choose to correct full throttle auto shifting we offer ES modules that correct the speed readings. The modules and rear seal kits are listed in the TRX420 section and also located in the "Parts" section of the site. Pic is for example only and may not show correct size.
All of our reductions carry a lifetime warranty to the original purchaser. We've been making reductions for approximately 10 years now with 20+ years of machining and metal-working experience. We've been repairing and modifying ATV's in general since the late 90's.
All reduction orders come with a free t-shirt! Please include your shirt size in the notes of your order (M, L, XL or 2XL). To purchase additional shirts use the link below.
