    are there any advantages to running a lenco reverser with the shift lever on either side - the passenger side vs the driver's side of the lenco? does the side of the lenco reverser lever effect the internal oiling of this case? any side of the lever more prone to internal breakage than the other side?

    just personal preference. which hand do you plan to use when shifting it.

    It makes almost no difference as to what side or the other. The only thing that you have to make sure is that the slot in the aluminum cover that goes over the sprag assemble has the slot in the most down position that you can put it in. Nothing else changes. The strength and relaibilty is the same.

    lenco/reverser

    thanks for the answers - i run a pnut 3 speed in a dragster. i have run the reverser lever on both sides. just wondering if one side is stronger than the other. i use a synder shifter for the reverser and air pods for the front cases. i have talked with both david and matt at lenco in regards to making the reverser stronger - a pnut is only rated for 1100 hp but i have to use it due to its shorter length. i was just making sure that there wasn't some strength to be gained based upon the side of the unit that the reverser lever is located. i've had matt tweak the reverser to make it wider to help from grinding after making the burnout when shifting from foreward back into reverse. after backing up from the burnout i can have the car rocked/rolled to ease the changing from reverse to foreward.

    One thing that can make the reverser grind after a burnout is that the clutch heated up and expanded and is nor dragging so the shaft through the Lenco is turning and thedriveshaft is not....they will grind. One solution is to use more airgap or lower idle RPM. Do you know what Matt did to tweak it???

    I thought some would rotate the reverser 180 degrees to put the lever on the other side so you would actually pull back for forward position and shift the lever forward for reverse, so that it would not want to pop into neutral during the launch...??? i could be confused on this...

    Josh, that is what we have always done. I like having the reverser lever back for forward gear, just seems to make more sense to me that way - you get used to it really quickly.

    Our Lenco lever has a guide with notches in it that lock it into FWD, REV or NEUTRAL. The driver pulls up on a ring below the shifter knob to release the lock. One handed.

    lenco/reverser

    mike - i heard about a wide neutral reverser. matt either added shims to the reverser or took the reverse gear on a belt grinder to "tweak it". i could acutally feel the difference after he worked on it - the distance between reverse and foreward was farther apart thus giving me more room to adjust. the only way to change the reverse/foreward relationship for the driver is to change where the cable picks up the lever. since changing the lever from driver's side to passenge side doesn't change the relationship above or below the reverse gear - the only way to effect where foreward or reverse is for the driver - is to lengthen the lever and pick up the cable point at the opposite end of the lever. sounds complicated but look at the lever with the point where it goes into the reverser as the center of the lever - one direction pulls and the opposite end of the lever pushes. whence depending on where you pick up the lever with a cable will result in the foreward/reverse direction for the driver.

    lowcountry, by rotating the entire reverser case you can get the lever to the other side. On one side it will be pointing up, on the other down. This will change the fwd/rev relationship for the driver. This ofcourse is for a funnycar situation where the driver uses a handle that is mounted directly to the reverser lever, in a dragster you are right, you have to change where the cable attaches.

    Lowcountry,
    I believe you're correct on that, but I was referring to actually bolting the reverser to the lenco upside down (180 degrees from where it should be) So to get the slider to engage in the forward position you'd have to pull back on the for/rev shifter, as long as you still have the cable/connection point on the lever (on the reverser, no the shifter) pointing to the top of the car (up). You obviously have to then take the lever off and point it up, for it'd be pointing down with out remounting.

    Mike we use the same notched shifter bracket. They seem to still be a little sensitive on the adjustment. We had to make it where you were engaging as soon as you pulled it out of the neutral slot, yet it still sometimes will pop into neutral after completing a burnout. Nice to have that neutral cut out in the reverser gear, but makes for that much less surface area for bite.

    I just installed a new gear for the forward engagement gear in my reverser and Lenco asked me if I wanted neutral or not because the gear was a different thickness. He must have modified your gear to be like the newer ones.
