Fits 2001-2015 Allison Equipped GM Trucks

Control your torque converter from the palm of your hand with the AlliLocker™ from Fleece Performance Engineering.

The AlliLocker™ is 100% code free* when used on the track and allows you to bypass the TCM to lock/unlock the torque converter on demand. Turn the bypass switch off, and the TCM regains control of the torque converter clutch.

*The AlliLocker is NOT desinged to be used on public roadways. If used on public roadways, the AlliLocker may set a DTC causing a range shift inhibit. This can typically be cleared by a key cycle. When used on the sled pull or drag race track, where there is only one lock event, the AlliLocker will not cause a range shift inhibit.

Operation explained in plain English:

The Allilocker™ operation is simple. Leave it in normal mode until you want control of the torque converter clutch (TCC). When you engage bypass mode (left rocker switch) the TCC is completely controlled by the pushbutton on the right (it is a latching pushbutton). If you press it down it locks the TCC and stays locked until you push it again which raises the switch back to the open/unlocked position. 

WARNING: This product is intended for closed course race use only. Do NOT use on public roadways.

WARNING: Always disengage the bypass switch and unlatch the lock switch when not in use.

Decent Slim Fit Tux
Color: Midnight Black, Size: Large
This will work. In ordering the tux I don't recall seeing the set advertised as slim fit but it definitely is. My husband is 6'2" and 185 lbs. and is a runner. This suit just fits. The pants are thankfully long enough (he wears a 34/34) and the vest fits well however there doesn't seem to be an inch to spare in the jacket. He says it feels fine on, doesn't feel too snug, so that's all that matters. He needed a tux for a black tie wedding we'll be attending next month and this will fit the bill at a good price for something he'll likely never wear again. Note: the Suit comes folded up in a plastic bag and will need to be pressed before wearing.

Can’t believe it was this cheap! Looked just like the suits friends were paying hundreds of $ for to not even buy but to rent. Would definitely recommend buying from here!

I'm going to be fair on this one
Color: Black, Size: XX-Large
TLDR; Ordered one (XL), too tight. Then ordered a size up (XXL), it was ok-ish but the sewing was horrible. Ended it up returning both and I still give them 4 stars (because this review is fair) So to my review: I wanted to like this suit. It had great reviews and it is, in all honesty, not that expensive. When I ordered the first suit (XL) I noticed that the fabric was super cheap but somewhat passable. The jacket did not close at all but the pants fit and they were surprisingly decent-ish. It is a slim fit suit so take it from there... the pants were tight in the leg BUT I did welcome A LOT the fact that comes with an elastic waist so it is pretty adjustable. THAT right there is probably one of my favorite things about this suit. I was on the fence of liking this suit so I thought maybe if I tried a bigger size it would made a difference. So then I ordered an XXL and arrived the next day, great. Tried it and the jacket now fit but the pants were not the best fit of all... don't get me wrong, the elastic waist worked great and it was helpful but I definitely needed a belt for this one. Regardless, upon inspection of the new jacket I noticed that the one side was uneven. In the back, there is a separation between both sides, joined by a thin thread that joins both flaps together. You could tell that one side was longer than the other. I was upset but gave it some thought because this is what happens when you buy these type of things online, you are bound to find some items that may or may not work for you. By the way, it comes with a nice vest (waaaaay too tight regardless the size) and a bowtie, which, in my opinion, just don't bother with this one guys Truth be told, you can get a suit from a brand name retailer (on sale) for about $150- $200 that you might not encounter those QC issues but you might not have the same features as this one. Unfortunately, I don't have the time hoping the next one will be perfect. It has it place in your life. If this is for a kid, prom, maybe a cheap wedding that you have to attend, it has its place given the price and features, but if you are going to use it for a gala event please don't, you will NOT look great.... that is why, even though I had to return both, I still gave it 4 stars and I will be buying a tux separates. More expensive, yes but it will also compliment my look completely. It won't be a one use only. Hope this helps P.S: Shipping has LOTS to be desired!! it comes in THE plastic bag that the suit comes folded in, nothing to protect it from the elements when its delivered, not even a shipping bag!!!. For that alone they will get a 1 Star (but that is on Amazon)
