Friday 3/20/20 UPDATE: Our HD Rear Output shafts are finally back! We are processing inventory and building kits now, and will be shipping these out by mid next week!
Due to the enormous demand, they are not eligible for our Spring Sales event. Thank you for your understanding!
Also, we've raised the Core Charge to $125 because people are not returning their old core parts. We don't like charging for a Core and it would be free if everyone would comply...
We just need three parts returned: • Your old Tail Housing, • Your old Oil Pump Gear, and • Your old Speedometer Drive Gear, and we will refund your hostage core charge! Thank you! (see second image above for parts reference)
Thursday 3/26/20 UPDATE: In stock and now shipping!
Proven 30-spline Marlin Crawler Design: 2-time National Formula Toy Champion and World-Record 6-time King Of the Hammers Top 25 finisher!
Our Toyota 1979-95 gear drive transfer case output shaft is the only RF1A shaft to feature 30-splines. It features an 52.3% larger cross section compared to the stock output, and it is made from super strong heat treated Chromoly steel. The increased spline count helps spread the load through our 135% thicker "4-30" HD flange. Additionally, our output shaft retains the factory oil pump so daily drivers can take part in the torque fest and we include an oversized version of our world famous EcoSeal rear output seal to keep your rig and the environment clean.
Kit includes everything you need to convert your rear output shaft to our massively oversized 30-spline Chromoly shaft:
Includes everything needed to install: Bored & oversized transfer case tail housing, oil pump, and speedometer gear, new front output drive hub, oversized bearing, "4-30" HD 30-spline flange, and chromoly 30-spline output shaft with matching flange nut. It fits any style RF1A gear drive transfer case, top or forward shift, 21- or 23-spline, stock gears or aftermarket gears.
This product requires a refundable core charge on your stock tail-housing.
