35% secondary 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. Wide open throttle auto shifting is affected but drivability is retained. If you choose to correct wide open auto shifting you will need to add one of our ES modules. The ES 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.
