Some internal clearance/cutting is required and models with speedometer 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 more details.

**ES models including Pioneer will need an ES module to prevent electronic shift issues. The ES modules and rear seal kits are listed in the 420/500/520 sections and also located in the "Parts" section of the site. Pic is for example only and may not show correct size.
