MPx Billet Input Shaft (23 spline!) w/ Straight Cut 1st & 2nd Gears, 03-05 Neon SRT-4

Model Number: 220168-23IPS-SET

We've done two things to drastically improve the strength of this input shaft over stock input shafts and our regular KW input shaft. We have removed the neck down after the clutch splines, and made this as large as physically possible.

With this input shaft you'll need to change your clutch disc to a 23 spline (stock is 17 spline) type. We can help with either custom ACT clutch disc that we keep in stock, or a full blown ACT clutch with 23 spline disc. Clutchmasters can also custom make single disc or with twin disc clutches with 23 splines. Contact us by email to discuss further.

Achieve the ultimate in acceleration with a stronger input shaft and close ratio gears. Not only will you have a stronger input shaft for your Neon SRT-4, you'll also experience an increase in acceleration in the lower gears.

  • Made from Japanese SAE 8620 and 4320 Steel
  • Forged, Double Tempered and Sub Zero treated for unsurpassed toughness
  • Advanced Shot Peening technology increases surface hardness
  • Uses a 3.00 taller gear ratio instead of a factory 3.65 gear ratio for first gear.

This item includes free shipping anywhere in the continental USA.

Please note, due to the design difference between 2003 and 2004-2005 transmissions, this input shaft/gear set will ONLY work on 2004-2005 SRT-4's.
