Offering this unique pair of gears (lower pair; foreground in photo) for Peerless 820-Series heavy-duty vertical-input transaxles to increase axle RPM with no increase in engine RPM. This Gearset allows the differential to be kept intact while changing the internal final-drive ratio from 8.02:1 to 5.61:1. This permits racers to run much closer to the 9:1 overall transaxle-ratio limit imposed by some class rules. If you want to run this gearset with a locked stock differential, see my Gearset Upgrade 4 Item ("Mower Racing Diffy-Lock Gearset; Peerless 1" Transaxle").

As noted above, these higher-ratio gears are shown in the foreground of the photo. The small gear has 19 teeth and the large gear has 31 teeth. These gears replace the original 15-tooth 778253 shifter/brake-shaft gear (Peerless 820 IPL Reference 7) and 35-tooth 778247 intermediate output-shaft gear (IPL Reference 6B) shown in the photo background (upper pair). The 19-tooth gear and the 31-tooth gear are custom-manufactured gears Made-In-The-USA from same-thickness SAE1117 alloy and hardened to Rc 58-62, the same alloy and heat-treat specification used for other original Peerless 820 transaxle gears.

FIT NOTE: This Gearset will only fit the 820-Series Peerless transaxles -- those with Model Numbers of 820-xxx. It will not fit any 900s, 800/801s, or the MST 200-Series transaxles. I do not have any high-speed gearsets for any Peerless Gear transaxles except the 820. If you need a faster transaxle, I would suggest upgrading to an 820.

This Gearset is not available from any other source. Being a non-stock gearset, purchaser agrees to be responsible for all usage of and liability for this gearset.

Price includes shipping within the USA: Gearset will be packaged safely and shipped USPS Priority Mail Insured with Delivery Confirmation within the USA immediately upon receipt of proper payment. I can ship this Item worldwide.

PAYMENT NOTE: If you are checking out the price on this Ad or are placing an Order, make sure the price does not say “AUD” after the Dollar amount. Also check that there is no ".au" in the Address Bar after "ecrater.com." “AUD” refers to Australian Dollars. If you are on the Australian eCrater site, it will show an “au” in the address bar. Remove the “.au” from the address bar, and you will then see the correct $90.00 U.S. Dollar amount.

QUESTIONS? I will be glad to answer any questions you might have.

No sales tax if this Item is shipped out of Missouri. Bates County sales tax of 5.225% must be charged to a Missouri Buyer.

FEEDBACK: Our Feedback is 100%, which is good. The latest Feedback, however, is in December of 2011, which may raise questions. The reason for this is because we had to drop PayPal as an Approved Payment Method in our Store due to eCrater’s restrictions, and the only way Feedback can be left is if we show PayPal as an Approved Payment Method and the Buyer pays with PayPal through the eCrater Checkout. For this reason, there are no Feedbacks since December of 2011, even though we’ve had hundreds of satisfied customers since then. If you would like to get a referral from a recent customer near you, please let us know. We have nothing to hide, and your satisfaction is our priority.
