Schaeffler LuK LSC265B Clutch Slave Cylinder, OEM Clutch Release Replacement Parts

I got this to replace a brand new sash unit that was making a crazy noise. Changed it out and no more noise.

This is a factory replacement for a C5 Corvette. Aluminum main body with different/ upgraded? hydraulic connections. Benkyo O'shimasu! (Japanese for study your stuff...)I installed this after the original slave blew its guts out. Here's why...The vehicle it went into is a 1988 Volvo 244 sedan. The engine in the car is a 2001 GM LR4 (DBC 4.8 Vortec) The transmission is an NV3500 from a 2003 4.3 V6 2wd 5spd S10 pickup rated for just under 400 ft/lbs...The NV3500 was mated to the 4.8 Vortec in 1/2 ton trucks, circa early-mid 2000's vintage. It all bolts up. Factory clutch slaves installed in those 1/2 ton pickups with the 4.8 had plastic main bodies.My Volvo is a track car. Road racing and Drift competitions. Likely runs high 12 second 1/4 mile times with a 3:31 rear differential ratio. On a good tune, it's a brilliant car. (Scary factory volvo Dana30 variant) [Ford 8.8 is in the making with 3.73s and 4.10s (spooled)]I cant afford a TKO600 or a T56 variant. Running the V6 S10 NV3500 gives better gear ratios compared to the 1/2 ton pickup NV3500 5spds. 1st gear in the pickups had a low ratio/lesser torque rating. 2nd gear may have been different too. I dunno, I didnt need it so I didnt try to put it to memory.Super high rpm gear changes (4k-6.5k), 2step launches at 3,000 rpm, a factory 1/2 ton truck plastic housing slave cylinder wont hold up. Absolutely not.How is it that I know?My cousin got married. So I drove the track car to/fro. Did a launch for my dirt track driver/NASCAR nut of an Uncle while being 200 miles from home. Plastic housing slave blew out. I shut the engine off 1 time driving it home aside from getting gas.Got the car home and up on jack stands. Pulled the motor/trans as one unit. Out the plastic crap clutch slave cylinder went. The main spring (which is inside the unit) was outboard the plastic main housing. Fluid poured right through it.I put this slave in, the C5 hydro thowout/slave cylinder with a metal housing....I'm not worried about hydraulics. I'm worried about the NV3500 holding up.Real good unit folks provided your application an fitment.

Good product. Very fast shipping. Happy with the product.

Had absolutely no problem with install or bleeding. If you have to replace the pressure plate and clitch playe, there is a kit id recommend over just this.

Replaced the slave after melting my old slave line bc it was hanging beside the exhaust. The line i used was Dorman 628-105, snug between the wheel well & firewall. I will have to install some release bearing/slave cyl shims however. Everything works as it should except my clutch does not disengage fully. I think the oil pan was too far back or had surface imperfectionsRemoved trans for NV4500 swap. The bearing is disgusting, the grey lube made its way to the face of the bearing. It's loose side to side like it could pop off. It makes awful noise when I spin it by hand. It's drivable. Leaking fluid.Replaced the slave with the same unit. What I like about this unit over the stock silverado slave is that this unit compresses more. More travel. This unit is metal instead of the plastic that comes stock in the truck

LUK throw out bearings are the best.

After 6k miles started to leak and will not go into first or reverse after 2 years of installation

Luk makes this exact piece for GM. Seems to be good quality. Installed on T56 Magnum F transmission
